Research Study Makes Case for Palliative Care Early in Parkinson's Treatment
When many first hear the term palliative care, they can misinterpret it as end of life care. However, palliative care is an option for anyone with Parkinson's disease (PD) to receive additional support, even at the point of diagnosis. It can help at any PD stage, specifically with treating pain management; encompassing spiritual care and helping people with Parkinson’s and their family navigate emotional challenges. It can also compassionately create a safe space for one to explore, and ultimately share, their end-of-life directives.
What if that level of holistic care wasn’t reserved for the final weeks of life, but rather was incorporated into standard care in the PD population? How might that impact the quality of life and symptom burden for people with Parkinson’s and their caregiver?
Recently published in the journal, JAMA Neurology, “Comparison of Integrated Outpatient Palliative Care With Standard Care in Patients With Parkinson Disease and Related Disorders: A Randomized Clinical Trial” (Kluger et al., 2020), a one-year comparative study investigated palliative care and its effects on patient and caregiver.
Study participants included 210 patients (135 men, 75 women), predominantly white, married, college-educated, with an average age of mid-60s. The caregiver participants were composed of 175 people (47 men, 128 women) — 143 of whom were the patients’ spouse. The study was conducted at three academic medical centers: University of Alberta (Alberta, Canada), the University of Colorado (Aurora, CO), and the University of California (San Francisco, CA).
Participants were randomly assigned to receive one of two courses of treatment:
The standard of care option: provided by a neurologist and a primary care physician.
The integrated palliative care option: included the standard of care, plus a chaplain, a social worker and a nurse using a palliative care checklist — who could also access additional guidance from a palliative medicine specialist. Palliative care visits were performed either in person or by telemedicine every three months.
The study primarily measured a change in quality of life of patient and caregiver burden. Also measured were: symptom burden; patient and caregiver mood (anxiety and depression); patient and caregiver grief and spiritual well-being; patient and caregiver patterns of health care use; motor symptoms; and, cognitive functioning.
Results
Comparing participants receiving palliative care with those who received standard care alone, after six months:
Patients receiving palliative care had better quality of life
Patients receiving palliative care had better symptom burden
Patients receiving palliative care experienced less grief
Patients receiving palliative care had better rates of completing their Advanced Directive Completion (end-of-life preferences)
Patients receiving palliative care had statistically and clinically significant benefit in motor symptoms
Comparing palliative care and standard of care caregivers:
Palliative care caregivers experienced less anxiety
No other significant differences were found in caregiver burden
What Does It Mean?
This study found that introducing palliative care significantly improves quality of life for people with Parkinson’s — not just emotionally, but also physically. The study authors share that while these motor improvements were unexpected, they may reflect, “an unanticipated benefit of our palliative care team’s general goal of encouraging activities that promoted joy, meaning and connection.” Additionally, the caregivers in the palliative care group also experienced less anxiety themselves — with no increase in caregiver burden. Interestingly, not a single outcome measure favored receiving standard care alone.
Of note, the study’s main limitation was its lack of diversity among study participants; more than 70% of the participants were white. Incorporating a far more diverse population needs to be included as this important research moves forward.
At its core, palliative care is a caring, holistic approach that optimizes quality of life for as long as possible. Loved ones and caregivers benefit as well, often transforming an otherwise frightening, overwhelming and painful journey into a sacred passage. Introducing this level of care and connection could make all the difference in quality of life.

Coping with COVID-19: Survey Results from People with Parkinson’s During the Pandemic
During the time of COVID-19 are people with Parkinson’s disease (PD) frequently experiencing anxiety? Are they using telehealth services to see their medical team? Are they exercising less or more often than before the pandemic? A Parkinson’s Foundation survey sought to answer these questions and more.
As the COVID-19 pandemic continues, little is known about its impact on the health and day-to-day activities of people with Parkinson’s. The Parkinson’s Foundation and Columbia University Parkinson’s Disease Center of Excellence administered a survey to people with Parkinson’s to provide guidance to clinicians, policy makers and the PD community on how COVID-19 has transformed the lives of people with Parkinson’s and their access to care.
“People with Parkinson’s encounter numerous difficulties during normal times, especially when it comes to receiving proper PD medications when admitted to hospitals,” said Phil Gee, Parkinson's Foundation People with Parkinson’s Advisory Council Member. “I am grateful that the Parkinson’s Foundation initiated this COVID-19 survey to capture how people with Parkinson’s disease are coping during this pandemic.”
What did the survey measure?
This survey was administered between May 2020 and June 2020, receiving 1,342 completed responses from people with PD.
The survey asked people with PD about their:
COVID-19 health status
Emotional health
Attitudes and practices related to changes in their routine since the pandemic began
Telehealth use and satisfaction
Results
Almost all survey respondents came from within the U.S. Respondents live across states that experienced all levels of COVID-19 infection. The average age for respondents was 71, and the average time they have lived with Parkinson’s was seven years.
Diagnosed with COVID-19 and Parkinson’s
Only 17 (1.3%) survey respondents with PD reported a COVID-19 diagnosis by a health provider, five of which had a test to confirm the diagnosis. Within this small group, the most reported COVID-19 symptoms included: fatigue (71%), muscle pain (59%), body aches (59%), cough (63%), headache (47%) and shortness of breath (47%). COVID-19 symptoms lasted an average of 13.5 days.
Mood
More than half of respondents experienced nervousness or anxiety (67%), feeling down or depressed (51%), reduced interest or pleasure in doing things (54%) or sleep disturbances (66%) in the six weeks prior to the survey. Women were more likely to experience these symptoms than men, with the exception of experiencing a reduced interest or pleasure in doing things.
Respondents who reported experiencing frequent mood disruptions (anxiety, worry, depression, reduced interest, sleep disturbances or isolation) during the pandemic where asked to explain why.
Anxiety was most often attributed to the fear of respondents getting infected (22%) and not knowing when COVID-19 would be resolved (13%).
Depression was most often attributed to the inability to see or have physical contact with family and friends (16%) and having a history a depression unrelated to COVID-19 (12%).
Loss of interest was most often attributed to not leaving the house (14%), having lost interest and apathy prior to COVID-19 (14%) and hopelessness or negative feelings about the future (13%).
Sleep problems were attributed to problems not related to COVID-19 (36%) or worry related to COVID-19 (34%).
Physical and Social Activities
Most people with PD (85%) felt that their personal life had changed during the COVID-19 pandemic. Nearly half of people with Parkinson’s noticed some negative change in their Parkinson’s symptoms during the pandemic, but most people with PD said they had no negative change in their relationship with members of their household (65%) or the frequency of their communication with others (75%).
Almost half of People with Parkinson’s (45%) reported reduced hours of exercise, and 73% reported a reduction in activities outside of their home. However, most respondents reported that activities were available online (82%), among whom 92% participated. The most common virtual sessions attended included exercise/wellness class (58%), support groups (32%), recreational classes (13%, religious services (46%), educational events (36%) and other (22%).
As a response to COVID-19, to help ease the challenges of physical distancing, the Parkinson’s Foundation launched PD Health @ Home ― an interactive series of virtual events designed for the Parkinson’s community. To date, more than 230,800 participants have participated in the virtual programming. Currently, PD Health hosts innovative weekly expert-led educational webinars, guided mindfulness sessions and tailored fitness videos. See all upcoming PD Health @ Home events.
Telehealth
This survey measured the use of telehealth services for people with PD during COVID-19. Telehealth use increased from 10% prior to the pandemic to 64% during the pandemic. Those with higher income and higher education were associated with telehealth use.
People used telehealth most often for a doctor’s appointment compared to other health therapies (mental health, physical therapy, occupational therapy and speech and language pathology). Among those who had utilized services, almost half (46%) preferred to continue using telehealth always or sometimes after the coronavirus outbreak had ended. However, having received support or instruction for telehealth and having a care partner, friend, or family member help with the telehealth visit increased the likelihood of using telehealth after the pandemic ended.
Key Takeaways
While better understanding the COVID-19 experiences of people with PD, looking at the bigger picture, survey results suggest several urgent unmet community needs.
Telemedicine or telehealth: the distribution of health-related services and information using technology. Prepare for your next telemedicine appointment with this blog article.
The most notable shift within the PD community is the widespread use of telehealth. Telehealth use significantly increased 54% during the COVID-19 pandemic. However, results made it clear that the PD community urgently needs the expansion of telehealth services to include additional physical, occupational psychological and speech therapies, along with more support for how to use telehealth services and better reaching underserved (low income) populations.
New strategies must be developed to make telemedicine more available to all prospective users. The COVID-19 pandemic has differentially impacted people from lower socioeconomic status and extending telemedicine services to economically disadvantaged populations may help reduce disparities.
Depression and anxiety symptoms were prevalent in people with PD during the pandemic. Household income and employment status were found to be important factors in predicting mood disturbances. Our data strongly suggest disparities across socioeconomic status in people with PD during the COVID-19 pandemic, with those of lower income far more affected by financial and employment uncertainties. Interestingly, factors such as location and local COVID-19 rates were not associated with mood symptoms. This suggests that communities deemed at lower risk of spread are not immune from the overwhelming influence of the COVID-19 pandemic on everyday life.
We must further explore the relationship between PD and COVID-19. Given the uncertainty of how long the hardship of COVID-19 and social distancing requirements may persist, we must identify ways to help the PD community throughout this period. Gathering accurate data on COVID-19 risk among people with PD and improving telemedicine by providing a wider range of services and making it more accessible is essential.
Symptom Management: Is it PD, Medication or Aging?
Shakiness, slowness and stiffness – key Parkinson’s disease (PD) motor symptom challenges – can be frustrating. Your PD doctor and other PD healthcare experts, such as an occupational therapist (OT), can offer management strategies to ease movement difficulties. Addressing movement issues early can keep you living your best life.
This article is based on a Parkinson’s Foundation Expert Briefing series on Symptom Management: Is it PD, Medication or Aging? “Exploring Motor Symptoms Co-Management: Occupational Therapy and Neurology” was presented by Lisa Warren, MHS, OTR/L, Occupational Therapist and Rehabilitation Manager, University of Florida Health Rehab, Norman Fixel Institute for Neurological Diseases, a Parkinson’s Foundation Center of Excellence; Parkinson’s Foundation National Medical Advisor Dr. Michael S. Okun, Adelaide Lackner Professor, Chair of Neurology and Executive Director Norman Fixel Institute; and Gretchen Rosswurm, 2020 Chair of the Parkinson's Foundation People with Parkinson's Council.
Cardinal PD Motor Symptoms
While there is no specific test to identify Parkinson’s disease, there are telltale primary – or cardinal – motor signs. These include:
bradykinesia, the medical term for slowness of movement.
These symptoms stem from a drop in the brain’s production of the chemical dopamine. When considering a PD diagnosis, a neurologist who has PD expertise looks for bradykinesia accompanied by either stiffness or tremor.
Co-Managing Movement Issues
Both your neurologist and occupational therapist use different methods to tackle motor difficulties. Integrating multidisciplinary movement therapies can help you move easier.
Bradykinesia
We all tend to move a bit more slowly as we age. Bradykinesia – PD-associated physical slowness – is more unpredictable and exaggerated than typical age-related slowness. It can manifest as difficulty initiating movement. Or you may experience unusual stillness, decreased facial expression or need more time to complete daily tasks.
Your doctor may review the medications you are taking to ensure optimal delivery or might recommend taking your medications up to an hour before tasks that require dexterity.
An occupational therapist may recommend allowing extra time to accomplish tasks or can suggest activities that boost dexterity, such as shuffling and dealing cards. And remember, it’s OK to choose accuracy over speed. Give yourself permission to take the time you need.
The formula to living well with Parkinson’s is different for everyone. Be flexible and commit to working with your healthcare team to discover what works for you.
Tremor
People who live with Parkinson’s generally experience tremor as a shaky hands, legs or chin, often occurring at rest. Tremor typically affects one side of the body. Severity can fluctuate throughout the day – and from day to day.
Doctors often treat resting tremor with combination carbidopa/levodopa medication therapy. This temporarily replenishes dopamine to ease movement. But more than 20 percent of people living with PD can experience medication-resistant tremor. In these cases, a movement disorder specialist can recommend other therapies, including deep brain stimulation (DBS) – a procedure where electrodes are implanted into certain areas of the brain and connected to an implanted pulse generator to block nerve signals that make movement difficult.
Emotional and physical stress can also increase tremors. An occupational therapist can recommend therapies to combat your specific triggers – from meditation and creating a comfortable sleeping environment to adapting a favorite hobby.
Check out the PD Health @ Home online program called Mindfulness Mondays to discover ways to decompress.
Rigidity
This PD-related stiffness can occur throughout the body. Rigidity may cause painful cramping, such as dystonia – muscle spasms and clenching associated with Parkinson’s. Stiffness can occur on one or both sides of the body.
One of the best things you can do to combat rigidity is to take your medication on time, every time. If that isn’t working, your doctor may augment your medications or consider Botulinum toxin injections, which can sometimes relax overactive muscles.
Stress management and regular exercise can also ease rigidity and improve many other symptoms of Parkinson’s. An occupational therapist can recommend stretches specific to your needs. Warm up, then stretch your muscles before putting them to work. Be sure to talk to your doctor before starting any new exercise.
Stretch frequently, minimize stress and consider practicing yoga. The Parkinson’s Foundation offers online PD Health @Home Fitness Fridays to help you stay active at home.
Postural Instability
It's important to remain active with Parkinson's. However, people who live with PD can experience balance changes that increase the risk for falls and injury. Your healthcare team can give you strategies to keep moving safely.
Your movement disorder neurologist should perform a balance test that involves your shoulders at every visit. Your reaction to the test helps your doctor determine instability issues and potential treatment.
Integrate early, consistent, year-round physical and occupational therapy and exercise that focuses on balance. Ensure your home is free of clutter. Make it safe and easy to navigate. Minimize multitasking when you are walking; focus on walking and moving safely. Take big steps and walk with confidence.

Weeding Through the Haze: People with Parkinson’s Share Medical Cannabis Experiences
Medical cannabis (or marijuana) is a complementary and alternative therapy of high interest for the Parkinson’s disease (PD) community. The Parkinson’s Foundation believes that this topic should be better understood, and has committed to doing so with a medical marijuana convening and its published guidelines, new articles, interviewing experts on our podcast and most recently, conducting a survey to better understand cannabis use among the PD community.
In the U.S., cannabis has become more widely available for medical and recreational use. However, little is known about the attitudes towards, and experiences with, cannabis use among those living with PD. To address this shortcoming, the Parkinson’s Foundation distributed a survey, Weeding Through the Haze: A Survey on Cannabis Use Among People Living with Parkinson’s, Disease in the U.S., to 7,607 people with PD in January 2020 and analyzed the 1,064 complete responses we received.
“It is important to understand how people with Parkinson’s disease are using cannabis, and whether they are basing their use on evidence-based recommendations or trial and error. This survey will help shed light on the community viewpoints and experiences surrounding cannabis use for Parkinson’s disease symptoms,” said Megan Feeney, MPH, Parkinson’s Foundation Associate Director of Community Engagement and survey lead.
Medical Cannabis and Parkinson’s
Managing Parkinson’s is complex. As the neurodegenerative disease progresses, so do its symptoms for most. Many symptoms, especially non-motor symptoms, are not effectively addressed with current medications. Many people with Parkinson’s have looked to medical cannabis to provide some relief. However, more research is needed to prove if and how PD symptoms are relieved when using cannabis, and if so, what type of cannabis and what dosage are most effective and safe for the consumer.
Nevertheless, there is an increasing interest in the use of medical cannabis. Currently, 47 of 50 states in the U.S. permit the sale or consumption of hemp-sourced cannabidiol (CBD) products with less than 0.3% tetrahydrocannabinol (THC), while 35 of 50 states have approved marijuana for medicinal purposes and 15 of 50 states permit recreational use of marijuana. Today, broad numbers of people with PD have access to cannabis.
Survey Results
The 1,064 survey respondents came from 49 states. The average age for respondents was 71, and the average time they have lived with Parkinson’s is seven years. The survey asked specific questions about cannabis use ― from symptom management to motivation for use and side effects ― and questions for those who do not use cannabis and why.
Experiences with Cannabis and Managing PD
Of the respondents who consumed cannabis:
25% used cannabis within the previous six months.
57% learned about cannabis use from the internet, friends or other people with PD.
64% had not received a cannabis recommendation from a licensed doctor or provider.
56% were not provided any information on how to use cannabis (such as dosage, type and frequency of use).
Most consumers reported their most common time of cannabis use is either in the evening or at bedtime.
Interestingly, 23% of consumers stated they stopped cannabis use in the previous six months, primarily due to a lack of symptom improvement. Of note, 76% of respondents did not use cannabis, primarily because there was a lack of scientific evidence supporting any benefits.
Experiences with Cannabis and Managing PD Symptoms
Among respondents, cannabis was used to treat motor and non-motor symptoms. When asked about associated symptom relief, most consumers reported that cannabis use led to a moderate or considerable improvement in the severity of anxiety, pain, sleep disorders, stiffness and tremor. Overall use and the level to which cannabis was reported to address motor and non-motor symptoms varied widely.
Negative Side Effects
Less than 13% of consumers reported negative side effects from cannabis use. We also asked non-consumers of cannabis if they had experienced any previous negative cannabis experience. Of these, about half reported negative side effects.
Combined, both groups listed their negative side effects as an increase in anxiety (30%), impaired coordination (20%), dizziness (20%) and “other reasons” (38%), which included sleepiness, confusion, worsening orthostatic hypotension.
PD Medication and Cannabis Consumption
Cannabis consumers rated non-motor prescription medications as less efficacious than non-consumers. Among all consumers, 85% reported that cannabis use had no impact on their prescription medication usage, and 89% said cannabis was not a replacement for their PD prescription medications.
Clinical Trials
Among all who responded, 82% were interested in learning more information about a clinical trial exploring the impact of cannabis on PD symptoms, and 62% were interested in enrolling in a clinical trial.
Key Takeaways
While better understanding cannabis experiences of people with PD, looking at the bigger picture, survey results show that:
A knowledge gap among people living with PD, which may be impacting their decisions about cannabis use, as a large portion of consumers reported not knowing the type, brand or dosage of cannabis they primarily use.
Among some consumers, reported cannabis use may have been beneficial for motor and non-motor PD symptoms including anxiety, pain, sleep disorders, stiffness and tremor. This is consistent with other research studies.
One in five survey respondents are current cannabis consumers.
Cannabis use did not have an impact on PD prescription medications.
Cannabis consumers see the limited effectiveness of cannabis for symptom management. Most consumers recognize that cannabis is not a substitute for their PD medications.

New Study: Parkinson's Foundation Center of Excellence Sheds Light on COVID Vaccine and Parkinson's
Life as we knew it changed on January 30, 2020. That was that day when the World Health Organization (WHO) officially declared the COVID-19 outbreak to be a Public Health Emergency of International Concern. Caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), COVID-19 can result in serious, life-threatening complications, regardless of one’s age, race, health status, geographical location, or socio-economic income and including people with Parkinson’s disease. In this article, we’ll examine a new study from a Parkinson’s Foundation Center of Excellence, Nijmegen Parkinson’s Center in the Netherlands, which recommends the COVID-19 vaccination for people with Parkinson’s, unless there is a specific contraindication.
Overall, we know that people with PD who contract COVID-19 are more likely to experience severe respiratory issues and have more difficulty recovering from COVID-19 – particularly among those with advanced PD, compared to people who do not have PD. Another additional concern for those with PD is that COVID-19 may trigger a worsening of both motor and non-motor symptoms and also may increase the risks of mental health challenges. These mental health challenges are known to be higher for people with PD living under social isolation, higher stress levels and without adequate exercise.
Expert commentary recently published in the Journal of Parkinson’s Disease, titled, “COVID-19 Vaccination for Persons with Parkinson's Disease: Light at the End of the Tunnel?” (Bloem et al., 2021), tackles the question of getting the COVID-19 vaccine for people with Parkinson’s using a scientific, evidence-based approach. Bas Bloem, MD, PhD, works at the Radboud University Nijmegen Medical Centre, a Parkinson’s Foundation Center of Excellence. The Nijmegen Parkinson Center is one 14 international Centers of Excellence and 33 others in the United States.
These experts closely studied the development and approval processes – including the thorough analyses of completed Phase III data as provided by vaccine developers in a transparent process with peer-reviewed publication of the full data sets. In other words, Bloem et al. (2021) were privy to all of the actual data, not just cherry-picked data. Additional COVID-19 vaccination information was provided by the Scientific Issues Committee (IPMDS-SIC) of the International Parkinson and Movement Disorder Society.
Results
Compared to the general population, the risk of SARS-CoV-2 infection causing serious, life-threatening disease seems higher for people living with PD, at least among those with more advanced disease.
The approved mRNA-based vaccines are not known or expected to interact with the PD neurodegenerative process.
COVID-19 vaccination is not known to interfere with the current PD therapies.
The types or incidence of side effects of these vaccines in persons with PD were observed to be no different than in the general population – pain and irritation at the injection site, fatigue, muscle pain, headache, low fever/chills.
The vaccines were observed to be safe for older adults, however caution is needed for the specific subgroup of very frail and terminally ill elderly persons with PD living in long-term care facilities; or for people with PD who have additional chronic illnesses.
Taken together, (Bloem et al., 2021) recommend COVID-19 vaccination with approved vaccines for persons with PD, unless there is a specific contraindication.
Vaccinated persons with PD must continue to comply with the public health guidelines to reduce exposure and to possibly reduce transmission of COVID-19.
Insights may change, conscious monitoring of newly emerging data from both trials and real-life vaccination programs is critical.
The authors did not examine the recently US FDA approved vaccine produced by Johnson & Johnson so persons with Parkinson’s and family members should not extrapolate the data from this recent study to apply to the new single dose vaccine. Hopefully more information on this approach will be available soon.
Key Facts about COVID-19 Vaccines
1. Vaccines do not use the live virus that causes COVID-19. The new Johnson & Johnson vaccine uses DNA and not RNA and uses an adenovirus (not the corona virus) to deliver the information necessary to protect against COVID-19.
2. Vaccines cannot give someone COVID-19
3. Vaccines do not interact or affect our DNA in any way
4. Vaccines never enter the nucleus of the cell – which is where our DNA (genetic material) is stored
What Does It Mean?
Both the Pfizer/BioNTech and Moderna mRNA vaccines met the high standards required for use authorization after rigorous data scrutiny and validation – as required in the normal US FDA vaccine approval process. This process is essential in determining not only safety and efficacy, but also that the vaccine benefits outweigh its risks. Today, in the United States, the death toll from COVID-19 topped 500,000 people; worldwide, it has been associated with more than 2,462,000 deaths.
Based upon the available data, the incidence of side effects in persons with PD have not been different than in the general population. The approved mRNA-based vaccines, Pfizer/BioNTech and Moderna:
do not interact with the neurodegenerative process in PD
have been shown to be highly effective in preventing the severe and even the mild forms of the disease
help the body more rapidly clear the infection. High efficacy (>90%) has been demonstrated regardless of race, gender, age, and medical conditions. How big of deal is greater than 90 percent efficacy? During the 2019-20 flu season in the United States, the overall effectiveness of the seasonal flu vaccine in children and adults was about 45 percent.
In their MDS COVID-19 Vaccine Statement for Patients, the International Parkinson and Movement Disorder Society and its Scientific Issues Committee included the following, “All considered, we have encouraged our community of health specialists to recommend COVID-19 vaccination to their patients with PD (or their responsible caregivers) unless there is a specific reason that precludes administration. We also recommend that patients come forward to seek the vaccine as quickly as it is available.”
Finally, as stated by the experts, Bloem et al., (2021), even after being fully vaccinated, it is important that persons with PD continue complying with the public health guidelines to reduce exposure and transmission of COVID-19 as recommended by WHO and the CDC.

While it’s known as a movement disorder, people who live with Parkinson’s disease (PD) experience many non-movement, or non-motor, symptoms too – though not all of them are related to the disease. Peripheral neuropathy, or nervous system damage, fatigue and GI issues are common PD challenges that can also stem from other causes. Working with your doctor to identify the source of your symptoms is key to effective treatment.
This article is based on the Parkinson’s Foundation Expert Briefing series; Symptom Management: Is it PD, Medication or Aging? Exploring Non-motor Symptoms: Neuropathy, Fatigue, GI Issues presented by Ellen Walter, Nurse Practitioner, Cleveland Clinic, and Steven Swank, Clinical Pharmacist, University of Kansas Medical Center. Both organizations are Parkinson’s Foundation Centers of Excellence.
Causes of neuropathy, fatigue and impaired gastrointestinal (GI) function during the course of PD can be wide-ranging – and include everything from normal aging to medication side effects.
With any health challenge, it’s recommended to log symptoms. This can help your doctor rule out potential causes. When did symptoms start? Are there any patterns?
Neuropathy
Peripheral neuropathy describes damage to the nerves that carry messages between the brain and spinal cord. Although they may not know it by name, people who live with PD are more likely than others to experience peripheral neuropathy. It can cause pain, numbness, tingling or muscle weakness, or greater sensitivity in certain areas.
This condition can also cause loss of coordination or sometimes make people feel as if they're wearing gloves or socks. Due to increased risk for walking problems and falls, a falls risk assessment is critical for anyone living with Parkinson’s who experiences peripheral neuropathy in their legs.
Possible Causes
While there can be a connection to peripheral neuropathy and Parkinson’s medications, research shows people with PD can have neuropathy even before beginning treatment.
Other types of neuropathy are also more common in PD, including:
neurogenic orthostatic hypotension –is a sharp drop in blood pressure that happens when a person gets up from bed or from a chair, causing dizziness or even loss of consciousness
gastroparesis, a slowed down or delayed emptying of the gut
damage to nerves in the bladder can cause urinary incontinence
Neuropathy can also be related to more serious issues, such as alcoholism, diabetes, thyroid or kidney disease and even cancer. Let your doctor know right away if you experience neuropathy with any red flag symptoms, including:
bone pain
weakness
frequent unexplained infections
Early diagnosis and treatment can prevent permanent damage.
Medication-related Neuropathy
Some medications can also cause neuropathy or vitamin deficiencies that lead to neuropathy. Proton pump inhibitor (PPI) medications such as esomeprazole (Nexium) and omeprazole (Prilosec) block stomach acids and can also lead to vitamin deficiencies that spur neuropathy.
The diabetes medication metformin can lower vitamin B12 levels which can also cause neuropathy. People taking it should have their B12 levels checked regularly.
Though it’s not completely understood how it happens, long-term carbidopa/levodopa use can increase neuropathy too. Duopa carbidopa/levodopa intestinal gel therapy is more likely to cause peripheral neuropathy than oral tablets or capsules.
Other therapies that can cause neuropathy include:
Some chemotherapy treatments
Some immune suppressants
Nucleoside reverse transcriptase inhibitors (NRTIs), HIV medication
Amiodarone
Colchicine
Disulfiram
Hydralazine
Hydroxychloroquine
Metronidazole
Nitrofurantoin
Phenytoin
Similar Conditions
Restless leg syndrome and peripheral neuropathy can both cause an uncomfortable sensation in the legs. Sometimes people will say they have restless leg syndrome but actually what they're describing is neuropathy.
Neuropathy pain can sometimes be mistaken for arthritis, too. Neuropathy is often described as a burning, prickly, sharp or throbbing pain. Arthritis can also be described as throbbing pain, but it’s often accompanied by tenderness and joint stiffness
A common misconception is that deep brain stimulation (DBS) – a procedure where electrodes are implanted in the brain and block nerve signals that impair movement by way of a pulse generator – can cause peripheral neuropathy. It doesn’t, but tingling can be a stimulation side effect. An in-office device adjustment can usually fix this.
Treatment
Neuropathy treatment requires identifying the underlying causes. When vitamin deficiency is the cause, supplementation can lessen neuropathy and stop nerve damage.
Medications that can alleviate nerve pain but don’t stop nerve damage include:
Selective serotonin and norepinephrine reuptake inhibitor (SNRI) antidepressants duloxetine and venlafaxine.
Tricyclic antidepressants, such as nortriptyline.
Topical treatments including capsaicin cream and lidocaine cream or patch.
Onabotulinum toxin injections, such as BOTOX®.
Percutaneous electric nerve stimulation is a nonmedication therapy to help people with urinary incontinence due to neuropathy.
Fatigue
Excessive daytime sleepiness describes someone who falls asleep mid-conversation. Fatigue is different. Better explained as extreme exhaustion, about 50 percent of people with PD live with mental or physical fatigue. It can start early in Parkinson’s and persist throughout the course of the disease.
Possible Causes
The chemical changes that cause PD movement problems can cause fatigue. PD dyskinesias, involuntary dance-like movements, can leave those who experience it exhausted, too.
Left untreated, common PD sleep disorders can cause fatigue. Vitamin deficiencies, lifestyle habits, including a lack of regular exercise, alcohol use, poor nutrition and other diseases or disorders can also cause fatigue.
Watch for sudden onset of other symptoms associated with fatigue, including:
Shortness of breath
Weight loss
Signs of abnormal bleeding
Fever
Enlarged lymph nodes
Irregular heart rhythm
While not necessarily connected to fatigue, PD dopamine agonist medications such as pramipexole, ropinirole and apomorphine can cause sleepiness and sleep attacks. People with PD who drive or operate machine and take such medications should pull over if they feel tired. Rest or have someone else drive.
Medication-related Fatigue
Some medicines and PD treatments can cause fatigue, too. These include:
Medications that treat depression, a common PD symptom
Over-the-counter sleep and allergy medications, such as diphenhydramine
Beta blockers, such as metoprolol or carvedilol, sometimes used for tremor-control
Neuropathy medications
Blood-pressure medications
Dopamine agonists apomorphine, pramipexole, ropinirole and rotigotine
Levodopa
Amantadine
Treatment
Treating fatigue can sometimes be as simple as making lifestyle adjustments, including eating healthier, following a regular sleep schedule and getting daily exercise.
It’s also important in Parkinson’s to limit motor fluctuations, or “off” times. Work with your doctor to ensure your PD medications are lasting as long as they should – you may need a dose or timing adjustment.
One medication that has been shown to help with PD-related fatigue is rasagiline. There is insufficient evidence for other medications, such as methylphenidate or modafinil.
GI Issues
About 80% of people with Parkinson's experience GI issues. These can occur throughout the gastrointestinal tract, from drooling and swallowing problems to intestinal blockage and constipation, one of PD’s most common GI symptoms.
Though constipation is often defined as difficulty emptying the bowels or small, hard stool, watery stool can be a sign of severe constipation or impaction. Potentially life-threatening, impaction can lead to bowel obstruction or a tear in the colon.
Constipation can cause a bloated or full feeling, acid reflux, nausea or cramping. A build-up of hard stool can also cause vomiting.
Possible Causes
Many who live with PD experience constipation long before they are diagnosed. It can stem from many causes, including the neuropathy-related delayed emptying of the gut mentioned earlier, gastroparesis. Gastroparesis slows and weakens stomach muscle contractions, delaying digestion.
PD-related movement difficulties may make it more difficult to travel to the bathroom, so someone may limit their fluid intake, increasing dehydration and constipation. Movement difficulties may also limit exercise, which can help alleviate constipation.
As people age, GI issues are more common. Diabetes, thyroid disease and others can also slow gastric emptying. Damage to the vagus nerve from childbirth or surgery can cause constipation, too.
It’s important to call your doctor right away should you experience any red flag symptoms, including:
Frequent, persistent abdominal pain
Blood in your stool
Watery stool
Unintentional weight loss
Fever
Medication-related GI Issues
Constipation, nausea and vomiting are common medication side effects. Diuretics, or water pills, such as furosemide (Lasix) can pull water out of the body, causing constipation. Doctors often avoid prescribing older people diuretic or dehydrating medications as they already face increased dehydration risks.
Used to treat blood pressure, diuretic hydrochlorothiazide (HCTZ) can also cause constipation and is associated with a drug interaction with PD medicine amantadine.
Anticholinergic medications are those that can slow gut movement. They include oxybutinin and over-the-counter diphenhydramine.
PD-related gastroparesis can also impact how medications are absorbed. Most medications taken by mouth are absorbed in the stomach or further below it in the small intestine. People with decreased gut motility may find PD medications such as carbidopa/levodopa take longer to take effect or seem less effective.
Stomach acid-blocking proton pump inhibitors (PPIs) such as esomeprazole (Nexium) can increase the risk of a condition called small intestinal bacteria overgrowth (SIBO), experienced by up to 50 percent of people with Parkinson’s. SIBO can also cause levodopa and other medications to take longer to work, wear off more quickly or not work at all, because they must travel to, and through, the stomach to be effective.
Some gut bacteria, such as enterococcus faecalis, can actually breakdown levodopa itself. H. pylori, a type of stomach infection, can also decrease levodopa absorption. Antibiotics can help with SIBO and H. pylori.
Treatments
Your doctor can help discover and treat GI issues and they might refer you to a gastroenterologist, a doctor specializing in GI issues.
Eating fiber-rich foods and decreasing starchy ones, drinking more fluids and increasing exercise can all minimize constipation. Dopaminergic medications – those that replenishing or mimic dopamine in the brain – apomorphine injections, BOTOX® injections and biofeedback techniques can also alleviate the increased straining, pain and incomplete bowel evacuation common in Parkinson’s.
Treatment Tips
Bring a complete list of current medications, including any over-the-counter medications or supplements, to every doctor’s appointment. Also include a symptom log. Remember to describe what you are feeling, rather than using medical terms. This can help your healthcare team differentiate conditions and determine treatment.
Choosing one pharmacy to fill all of your medications is also helpful, as the pharmacy can flag any drug interactions.
Order or download the Aware in Care hospital kit. This can help your healthcare team understand what prescription medications you are taking, the importance of timing your medication and other vital information.
As the Pfizer/BioNTech, Moderna and Johnson & Johnson COVID-19 vaccines become more widely available across the United States, and data shows vaccine safety and benefit in those with Parkinson’s disease (PD), people are looking to brighter days ahead. This Facebook Live was conducted prior to U.S. Centers for Disease Control Announcement (CDC) that they will be pausing Johnson & Johnson vaccines out of an abundance of caution while investigating reports of rare and potentially dangerous blood clots. Dr. Anthony Fauci from NIH has stated that people who have already received the Johnson & Johnson vaccine will still receive the COVID-19 benefits. Continued monitoring for potential blood clots should be performed with your local doctor.
In an April 8 Parkinson’s Foundation Facebook Live event, “Life with Parkinson’s After the Covid-19 Vaccine,” Parkinson’s Foundation National Medical Advisor Michael S. Okun, MD, answered questions from the PD community about what post-vaccine life might look like.
“We have seen a categorical worsening of Parkinson’s symptoms during the COVID-19 pandemic and that's because people have been stuck at home without the ability to seek care,” Dr. Okun said. “Vaccines are one of the things that are going to help.”
Dr. Okun: This is one of the safest vaccines that we’ve seen. We have data on tens of thousands of people who have received the available immunizations and how they fared. The safety record has been outstanding. Nonetheless, health authorities continue to track side effects from the vaccines to ensure their ongoing safety. For example, on April 13, the FDA and CDC determined that administrations of the Johnson & Johnson version of the vaccine should be paused so researchers can investigate a possible link between it and blood clots. It should be noted that Johnson & Johnson uses a different type of platform for their vaccine than Moderna and Pfizer. The Moderna and Pfizer vaccines are not affected by the CDC and FDA’s announcement and have not been associated with blood clots.
The most common side effects of the COVID-19 vaccines are short-term, and include:
Headache
Fever
Chills
Nausea
Muscle, joint or injection site pain
Injection site swelling or redness
When these symptoms appear after a shot, they are in general all good things – it means your immune system is working. Long-term side-affects are rare from the vaccine. You have a much greater chance of having a long-term problem from COVID infection than from receiving the vaccine. In fact, although we don’t yet know why, some people living with “long-hauler,” persistent COVID symptoms – lasting fatigue, headaches and other symptoms – are improving after they receive the COVID-19 vaccine.
Dr. Okun: The COVID-19 vaccine does not cause multiple sclerosis or Lou Gehrig’s disease.
Dr. Okun: Our hearts go out to you and to everyone who has lost someone during these times. When we see possible associations to a vaccine, we look carefully at the data. We have not seen a statistical correlation that the vaccine causes death, and we're looking at very large numbers.
During the 1950’s polio epidemic, we had to pause the polio vaccine rollout to look for contaminants because we saw deaths associated with the shot. The problem was with a Cutter Laboratories vaccine that inadvertently contained live polio virus. This created a large-scale change in the way the Food and Drug Administration, and the world, treats vaccine development.
Today, the newest vaccines are designed to send the instructions to your immune system to fight COVID-19. The vaccine teaches your immune system what COVID-19 looks like and how to attack, it if you are infected. We now perform full-scale safety monitoring. If we see a concerning safety pattern, like they saw in 1955 with the polio vaccine, then we pause the program and investigate. Right now, we have paused the Johnson & Johnson vaccine to examine a potential association with blood clots.
Dr. Okun: The vaccine won’t change long-term symptoms, but you may experience short-term side effects, such as those mentioned above. These side effects are common. Your body is responding to the vaccine as the instructions in the vaccine teaches your immune system to make antibodies against COVID-19.
We also know that stress, anxiety and sleep deprivation can all worsen PD symptoms, and getting a vaccine can for some, be a source of anxiety.
Dr Okun: We don’t expect the COVID-19 vaccine to cause or to worsen Parkinson's disease.
When we administer a vaccine for any disease, we focus heavily on documentation – what we call case report forms. Every time we give a vaccine, if somebody reports something, we write it down on one of these case report forms. Regulatory authorities monitor these reports. We've also enrolled a lot of people in long-term studies to monitor how the vaccine will affect people over time.
PD is not an expected vaccine side effect, but if it did happen – if somebody sort of popped up with Parkinson's – then we would want to know about that emerging issue- and we would definitely document it.
It's amazing to think about the large number of people that have been vaccinated so far in this program without major statistical problems – it's breathtaking in terms of the number of lives that have been saved.
Dr. Okun: Moderna and Pfizer vaccines have a very similar safety record, and researchers are investigating a possible link between the Johnson & Johnson vaccine and blood clots that have been reported in six women between the ages of 18 and 48. The Pfizer and Moderna vaccines require two shots, while the Johnson & Johnson vaccine only requires one. In general, we seem to get more effectiveness against COVID-19 using a two-shot approach – but all three are effective in preventing the long-term side effects of COVID-19 and preventing hospitalizations as well as death. The Johnson & Johnson vaccine program is currently paused so researchers can investigate a possible link between it and blood clots.
Dr. Okun: We don't have the exact answer to that question, but we're starting to get some clarity. If you had COVID-19 you should still be vaccinated. The Centers for Disease Control (CDC) is looking at this question. We don’t know how long it’s safe to not be vaccinated after you’ve recovered from COVID-19 or how long does the protection last. We are assessing whether an unvaccinated previously affected person can be with someone who's vaccinated and for how long they may get protection from having had the actual COVID-19 virus.
We have seen people with COVID-19 infection who do not have antibodies a few months down the road. The CDC is examining this issue but in general we recommend that people with Parkinson’s who had COVID-19 get vaccinated 6-8 weeks after the infection. This may change with more guidance from the CDC.
Things are evolving quickly in the field and we want to make sure that we get you as much information as we can in-real time, so be sure to frequently check Parkinson.org/COVID19 for updates on the COVID-19 vaccination.
Dr. Okun: The highest COVID-19 mortality rates are among the elderly, so many countries – including the United States, Europe and the Netherlands – have prioritized vaccinations in people over 65. Many of the elderly population reside in nursing homes. The vaccine makes a lot of sense for most cases of elderly people and for people at nursing homes.
The Dutch study is specifically referring to handful of rare exceptions – extremely frail or terminally ill people, or those who don’t want their lives prolonged. There are also a group of people who cannot consent due to memory loss and dementia.
It’s important to talk to your doctor. It’s also important to have the conversation: “What do you think this person would want us to do if they had capacity to consent?” If the goal is prolonging life and preventing COVID-19, the vaccination might be the answer. For people who are terminally ill, very frail and at the end of life, you could make an argument that you should talk about it before administering a vaccine that could prolong their life.
Dr. Okun: I wrote an op-ed for The Daily Beast a couple of months ago on exactly this question. We’re calling for an “Operation Warp Speed” for Parkinson’s disease – just like the national program that drove the rapid COVID-19 vaccine development. The National Institutes of Health (NIH), the world’s largest funder of medical research, sequenced the genetic information for COVID-19 shortly after the first case was documented in December 2019. The institution then shared the information with pharmaceutical and biotechnology companies like Moderna to quickly develop vaccines.
Not only did the industry make some of the more old-fashioned vaccines (like the flu vaccine) to protect against COVID-19, but a lot of our medical researchers were also previously working on a technology called messenger RNA (or mRNA) vaccines (intended to create and deliver specific immune system defense instructions). They were able to use this technology to create successful COVID-19 vaccines, thanks largely to prior research on viruses supported by NIH and other funders across the globe.
Dr. Okun: The Moderna and the Pfizer vaccines – with an overall efficacy of 94% and 95% – were designed as two-shot vaccines and they were tested in clinical trials as a two shot approach; they are messenger RNA (or mRNA) vaccines, which use single-stranded RNA technology to create a COVID-19 defense. The Johnson & Johnson vaccine has a 66% efficacy (but the same effectiveness at preventing hospitalization and mortality as the other two vaccines) and uses DNA technology to deliver the instructions to fight COVID-19. It was designed as a single shot.
We don't know whether two shots of the Johnson & Johnson would increase its efficacy up to where the Moderna and the Pfizer vaccines are, but all three – including the single-shot vaccine – are keeping people out of the hospital.
Dr Okun: As more data comes for each of the vaccines, we will be able to answer this question individually as it may differ. The hope is that you'll get at least a year of protection. The data on people who are in vaccine trials will tell us more about the length of protection.
Examining the length of protection of the vaccine is tricky because viruses like COVID-19 mutate to survive. The B.1.1.7 coronavirus variant – first identified in the U.K. – is the dominant strain of COVID in the U.S. today, different from the dominant strain that was here in March. We might need to administer the COVID-19 vaccine annually based on what we think the dominant strain will be, much like we do with the flu vaccine. We will need a strategy and it will likely include yearly vaccines for years to come.
Dr Okun: We can convince more people to consider the vaccine by starting out on the right foot. We have to respect each other’s points of view.
It's OK for people to be scared – it's OK to question whether the safety record is there. You should be doing that. We now know that people who are vaccinated very rarely die of COVID-19-related complications – statistically close to zero. I think that's a powerful fact.
Almost everybody wants the information. If you can share the information with them and have a positive dialogue and respect their points of view, I think more people will come around to the vaccine, particularly as the safety record continues to evolve. Sharing with people that you respect their decision and that you are grateful to have a dialogue will take us farther in overcoming vaccine hesitancy than shouting and fighting.
Dr Okun: Mutations are very common in coronaviruses. Sometimes the mutations are easier to treat and sometimes they're harder to treat. The vaccine is still active, but the longer we give the virus to continue to mutate the worse chance we have of beating this thing. This is why it’s important for us to get our vaccines, put our masks on and distance. If we don't do these things and we let this virus crawl back in, and keep mutating, eventually it could beat the vaccinations. That's why it's so important for us to continue masking even though we are vaccinating.
Dr. Okun: If you are fully vaccinated, current CDC guidelines say yes, you can gather indoors – without masks or staying 6 feet away – with vaccinated (and in some cases unvaccinated) people from one other household. It’s important to be sure none of them is at risk for severe illness from COVID-19. They can still give you COVID, although you may end up being asymptomatic, because you’re vaccinated. We still don't know if you could carry it back to them, but it's a theoretical possibility. It’s probably safest to wear a mask, but certainly some quick, masked hugs are OK. Social contact is really important, but maintaining small social groups, socially distancing and keeping your mask on are all critically important too.

Study Examines Connection Between Diabetes Medication and Parkinson's Disease
It was first suggested in the 1960’s that people with type-2 diabetes are at increased risk for developing Parkinson's disease (PD) – and when they do develop PD, its progression is faster and often more severe. This may be due, in part, to an apparent relationship in the brain between dopamine, insulin resistance, and glucose control. Insulin is not only made in the pancreas, it’s also present in the brain – where it has been shown to impact dopamine levels.
Parkinson’s is generally believed by scientists to be caused by the loss of dopamine-producing neurons. Parkinson’s symptoms, such as slowness, rigidity, and tremor, typically develop after approximately 40-80% of these dopamine-producing neurons die.
Why does this matter? Currently, more than 30 million people in the United States have type-2 diabetes, and that number is growing. The lifetime risk of developing Parkinson's is also on the rise. In light of these trends, it would be valuable to know whether any specific type-2 diabetes medications might be associated with an increased or decreased risk for developing PD.
A 40-month cohort study of over 100,000 patients with diabetes (Brauer et al., 2020) published in the journal, Brain, titled “Diabetes medications and risk of Parkinson's disease” examined the association between type-2 diabetes medications and the risk of developing Parkinson’s. Using patient medical records, the study authors compared the risk of developing PD in patients diagnosed with type-2 diabetes who took the following oral diabetes medications in various combinations:
1) Thiazolidinediones (also called glitazones), like pioglitazone (Actos) or rosiglitazone (Avandia), which specifically target insulin resistance
2) Drugs, like albiglutide (Tanzeum) or dulaglutide (Trulicity), that mimick glucagon-like peptide-1 (GLP-1) a hormone that promotes insulin secretion, and
3) Dipeptidyl peptidase 4 (DPP4) inhibitors, which increase GLP-1 levels, and lead to insulin secretion and lowering of blood sugar levels
The control (comparison) group were those individuals prescribed any other oral combination therapy for diabetes, such as metformin and sulfonylureas.
A wide variety of sophisticated mathematical analyses were conducted – with age, gender, smoking status, body mass index (BMI), and other known diabetes risk factors taken into account.
Results
The rate of Parkinson’s disease was 36–60% lower in the people who took DPP4 inhibitors and/or GLP-1 receptor agonists.
There was no evidence of any association between the use of glitazones and Parkinson’s disease.
No other medication or combination of medications demonstrated any statistically significant effect.
What Does This Mean?
In this large population-based cohort study, taking the medications DPP4 inhibitors and/or GLP-1 receptor agonists was associated with a lower rate of Parkinson’s disease. Based upon these findings of the possible protective effect of these medications, further studies are warranted and are currently underway. However, it is also important to note that an association is not the same as a causation. There may be other factors associated with taking certain type-2 diabetes medications that influence Parkinson’s risk.
Additionally, as noted by the study authors, while the results of this study may be useful for clinicians to take into account when choosing oral medications for treating diabetes, these preliminary results, “[…]cannot inform on the usefulness of specific drug classes on the rate of progression of Parkinson’s disease after diagnosis, nor on their efficacy among patients with Parkinson’s disease in the absence of diabetes" (Brauer et al., 2020, p. 3075). In other words, it’s too soon to tell, but the next phase of their research is already underway, where hopefully more definitive answers will be found.

Raising Awareness: The LGBTQ+ Parkinson’s Community Needs Better Care
Imagine being diagnosed with an incurable neurological disease, but afraid to reveal your identity because you might be denied care or enrollment in a clinical trial. Unfortunately, for many within the LGBTQ+ population living with Parkinson’s disease (PD), this is a common reality. Chi-Ying Roy Lin, MD, MPH, is an incoming neurologist at Baylor College of Medicine, a Parkinson’s Foundation Center of Excellence, who is advocating for the Lesbian, Gay, Bisexual, Transgender, Queer or Questioning plus other sexual identities (LGBTQ+) Parkinson’s community through research.
In his previous role as a Parkinson's Foundation Movement Disorders Fellow at New York-Presbyterian Hospital/Columbia University Medical Center, Dr. Lin noticed some life-altering issues his patients were grappling with. “Movement disorders is one of the least researched areas in the LGBTQ+ neuroscience field,” Dr. Lin said. The LGBTQ+ Parkinson’s community is so under-researched, there are currently no population estimates.
Estrogen and testosterone can be given as medically necessary gender-affirming hormones to match transgender people’s gender identity. How does this relate to Parkinson’s? At this point, testosterone was not found to affect Parkinson’s symptoms. On the other hand, the influence of estrogen on Parkinson’s symptoms remains inconclusive. Some research has shown that estrogen can play a role in providing protective benefits, such as lessening certain symptoms. Researchers also found that women with PD could have more motor fluctuations than men, challenging the idea of estrogen’s “protective effect” In PD.
What does this mean for trans women with PD who take estrogen therapy? “It is possible that trans women with Parkinson’s who take estrogen may see better or worse motor symptoms, which requires future research to tell us,” Dr. Lin said. “This is particularly important, as counseling about the stopping or altering of gender-affirming hormone for a transgender person, if necessary, is drastically different from that for postmenopausal or contraception purpose, considering the medical necessity of gender-affirming hormone to maintain mental health and life quality.”
Worse Parkinson’s Care Access and Experience
“There is a disparity in care among those in the sexual and gender minorities,” Dr. Lin said. “I have had patients who are reluctant to reveal their identity because of fear they will get denied healthcare.”
“We need to create a safe environment in healthcare institutions to disclose sexual orientation and gender identity to better impact care and access to resources,” Dr. Lin wrote in his study. Sex is a biological identifier generally determined at birth (male or female), while gender is a person’s identity (man, woman, transgender, non-binary).
Unfortunately, there is no LGBTQ+ patient guidance for multidisciplinary teams or care facilities. This coupled with ongoing discrimination and stigma against LGBTQ+ patients in healthcare, many people do not feel comfortable telling their doctor they are in a same-sex marriage or they identify as transgender. Seniors within the LGBTQ+ are particularly vulnerable. “It is not uncommon to see higher rates of violence or verbal abuse in nursing homes aimed at LGBTQ+ residents,” Dr. Lin said.
Identity Issues
Research, education, and advocacy can help address all these issues. The biggest obstacle right now for the LGBTQ+ Parkinson’s community is data. On a national level, most medical records list sex (female or male), but not gender (how a person identifies). “This continues to limit our research,” Dr. Lin said.
Knowing if a patient with Parkinson’s identifies as LGBTQ+ may help doctors provide customized treatments for movement and mood disorders. For instance, LGBTQ+ members typically experience higher rates of social isolation, so do people with Parkinson’s. If someone is LGBTQ+ and has Parkinson’s, they would be extremely prone to experience graver isolation issues that can lead to the worsening of non-movement PD symptoms, like depression or anxiety. To provide better evidence-based care, Dr. Lin would like to answer, “How does identity affect access to research and care?”
Helping the LGBTQ+ Parkinson’s Community
Policy-making and advocacy would change the course of treatment and care for the LGBTQ+ Parkinson’s community. “There are currently no guidelines at national or state level to help provide better care for the LGBTQ+ community,” Dr. Lin said. “There is a critical need for literature and best practices.”
Once created, guidelines would begin to address the disparity of care experienced by the LGBTQ+ community along with providing more tailored treatment options and help healthcare professionals follow best practices when treating LGBTQ+, Parkinson’s patients. For example, a nation-wide LGBTQ+ Parkinson’s guidelines can include affirming terminology for healthcare workers, an LGBTQ+-friendly and culturally competent provider list and proven ways to help the LGBTQ+ population feel more comfortable speaking to their care team.
“Do not be afraid to reveal your identity and community, said Dr. Lin when asked for his advice to the underrepresented LGBTQ+ Parkinson’s community. “I feel people in the medical community are relatively open-minded. If you are uncomfortable with your current specialist, reach out to other providers who may be able to give LGBTQ+ customized care. Telemedicine allows most people to find the right provider now. Also, try to be active in participating in clinical research and trials. Don’t be afraid to reveal who you are.”
