A person with Parkinson’s disease (PD) may experience visual, cognitive and mobility challenges as symptoms progress or as side effects from certain medications. Compromised vision can make it difficult to distinguish objects, perceive depth and safely maneuver a space while cognitive changes may make previously automated tasks (such as walking) more cumbersome.

Visual cues, however, can help a person with PD stay on track. See how members of our PD community have embraced color to train their brains:

Comfort in the Home

Our surroundings are important to us and contribute to our overall mood. Soft, warm colors are calming. Incorporate tranquil shades of orange, brown, red, yellow, orange and yellow-green to make large spaces feel cozier.

Flooring Around the Home

Carpet

A solid-color carpet is best. Solid colors emphasize boundaries between the wall and the floor and any changes in surface level. Large patterns or multiple colors can be distracting and make it more difficult to maneuver across a space. Be particularly cautious and try to avoid using patterned carpets and rugs on steps and stairways.

Stairs

Apply brightly colored tape on the top and bottom steps to signal the beginning and end of the steps.

Doorways and Hallways

Placing colored tape lines in a doorway can make it easier for people with Parkinson’s who have difficulty moving and experiencing freezing episodes. The tape provides a visual cue for where to place each foot when moving through the door. Taped lines can be placed down a hallway or in other places where freezing often occurs.

Bathroom Safety

Consider color contrast when installing grab bars and other safety items. For example, put a dark grab bar on a white wall. Also consider adequate lighting with few darkened or shadowy spaces.

Sitting

Changes in the brain can make it difficult for a person with Parkinson’s to determine proper body alignment when moving to sit down in a chair. This can result in the person attempting to sit down before his or her body is close enough or in proper position to sit safely. Marking the floor with a taped “x” provides the proper cue for where a person’s foot needs to be before sitting.

Maintaining Independence

Dressing

Choices allow a person to maintain their self-esteem and dignity.

Allow the person with Parkinson’s to provide as much help as he or she can with dressing. Even if physical or thinking changes prevent a person from accomplishing this on their own, it is important to offer choices. For example, asking whether they would prefer a red shirt or blue shirt can encourage participation.

Cognitive

Keep things simple to avoid confusion. Limiting options can help streamline an activity.

Remotes that only offer the “off”, “on”, “volume” and “channel” options can restore self-sufficiency when watching TV. Consider covering remote control buttons with tape to help minimize visual distractions and streamline productivity.

Overcoming Freezing

Use a mobile laser device that creates a colored line for you to step over. To combat freezing of gait, there are canes and walkers available that project a laser line to help cue steps.

Eating and Food

Utensils

Due to vision changes, contrast sensitivity in the eye makes it hard to discern objects that are similar in color.

People with Parkinson’s may have difficulty if the color of the food is the same color as the dish. Consider using dark dishes when serving light colored foods and light dishes when serving dark foods.

You can also use contrasting placemats under the person’s dish to outline the edges of his or her bowl or plate.

Nutrition

Incorporate foods high in antioxidants (which are important for overall brain health) into your diet. Eat brightly colored and dark fruits and vegetables. Cranberries, strawberries, oranges, beets, cherries, broccoli, blueberries and red kidney beans all deliver high concentrations of vitamins, minerals and antioxidants.

All Science News articles summarize a research study and are not an official opinion, endorsement or position of the Parkinson’s Foundation’s.

People with Parkinson’s disease (PD) commonly suffer from tremors and other movement symptoms, such as slowness and stiffness, caused by the loss of dopamine-producing nerve cells in an area of the brain called the substantia nigra. The cornerstone therapy for reducing these symptoms is the drug, levodopa. Often referred to as simply L-dopa, this drug works by helping to replenish the brain’s supply of dopamine. However, with long-term use of L-dopa, upwards of half of people with PD can develop levodopa-induced dyskinesia (LID) — a side effect that causes involuntary rapid jerking and twisting, or slow and extended muscle spasms. The severity of these side effects can range from bothersome to incapacitating.

A recently published study, titled, “Safety and tolerability of IRL790 in Parkinson’s disease with levodopa-induced dyskinesia—a phase 1b trial” (Svenningsson et al., 2018), investigated an experimental small molecule compound called, IRL790, which blocks a dopamine receptor called D3. Why D3? Studies in both animals and people with PD have found that long-term treatment with levodopa results in higher levels of D3 in the brain, which is believed to be what’s causing the LID side effects. Conducted at three university hospital outpatient clinics in Sweden, this was a randomized, double‐blind, placebo‐controlled study.

Ranging in age from 50 to 85, a total of 15 study participants with PD (9 men, 6 women) swallowed one oral capsule twice a day for four weeks of either IRL790 (11 people) or a placebo (4 people). All PD medications, including levodopa, were unchanged for at least 30 days and throughout the study period. Five clinic visits were required, with a follow-up phone call on day 21. A final follow-up visit was conducted within 10 days after the last dose. The starting dose prescribed for all participants was 10 mg (twice a day), with individual dose adjustments allowed up to a maximum of 40 mg twice a day, as needed. Doses were adjusted up to day 14 of the study, after which the dose remained stable.

The primary objective of this study was to investigate the safety and tolerability of the new drug, IRL790, including measuring frequency, seriousness and intensity of adverse events, physical examination, electrocardiogram (ECG) recordings, vital signs and safety laboratory measurements. To record movement data, i.e., dyskinesia and bradykinesia (slowness of movement), participants wore a kinetigraph device attached to their right or left wrist (their parkinsonian dominant side) for seven days priors to the study to establish a baseline, and then wore the device again for the last seven days of the trial.

Results

• A total of 13 participants completed the study. Two of the participants were withdrawn from the study due to possible adverse events associated with drug (one due to difficulty breathing and dizziness, and the other due to edema and redness of the feet).
• A total of 62 adverse events was reported by 14 participants (93.3%) — none were reported as serious and most could be mitigated by dose adjustments. All participants treated with a placebo experienced at least one adverse event.
• The average stable IRL790 dose was 18 mg daily.
• Among participants treated with IRL790, 55.5% were assessed as having an improved global clinical condition.
• Participants were reported to be in a steady state for plasma drug concentration after taking IRL790 for 14 days.
• Participants receiving IRL790 experienced a reduction in dyskinesia, without a reduction in the positive effects of levodopa.

What Does This Mean?

In 1961, L-dopa was hailed for its "miraculous" effect in people with PD (Hornykiewicz, 2010). However, by 1971 there were already studies investigating whether levodopa  was causing dyskinesias (Mones, Elizan, & Siegel, 1971). Today, we know that dyskinesia is a side effect associated with long-term use of L-dopa. Long term treatment with L-dopa results in making too much of the dopamine receptor called D3. While one may think that having a lot of a dopamine receptors sounds like a good thing for PD, in this case, it’s not. D3 is believed to produce the unwanted side effect of LID. The Svenningsson et al (2018) study supports this by demonstrating that by specifically blocking the D3 with the novel drug, IRL790, the negative LID symptoms could be significantly reduced without compromising the positive effects of L-dopa.

More than half of the study participants experienced less dyskinesia — and with no serious side effects. That’s not just encouraging, that’s groundbreaking. IRL790 may have the potential to become a game-changer in the treatment of PD. Of course, more research still needs to be done, as this was a phase 1 trial conducted in a small group of people. Researchers are already actively recruiting study participants for a Phase 2 clinical trial to help establish optimal dosing and are hoping to recruit 74 people with PD to participate (ClinicalTrials.gov, 2018).

This Parkinson’s Awareness Month, we want to hear your #KeyToPD.

Here are the Foundation’s top five keys to living a better life with Parkinson’s:

• ​Find a neurologist. Regular neurologist care can save the lives of thousands of people each year. Neurologist care saves about 4,600 lives each year in the U.S. alone.
• ​Get Answers. Call our 1-800-4PD-INFO (473-4636) Helpline or visit Parkinson.org to get your Parkinson's questions answered — at any stage of PD.
• Put together a care team. People living with PD who seek expert care have better outcomes — complication risks are lower, they enjoy better quality and longer lives.
• Establish an exercise routine. Increasing physical activity to at least 2.5 hours a week can slow decline in quality of life for people with PD.
• Get moving and socialize. Meet others with PD and families living in your area at your nearest Moving Day, A Walk for Parkinson's. Register at MovingDayWalk.org.

Parkinson’s disease (PD) is largely known for its motor symptoms, slow movement, tremor and stiffness, but other wide-ranging challenges, known as non-motor or non-movement symptoms — can often be most problematic. Treating these non-motor symptoms promotes optimal living.

The following article is part one of a two-part series based on a Parkinson’s Foundation Expert Briefings webinar exploring the latest research and treatments in PD-related non-motor symptoms, by Ronald Pfeiffer, MD, Oregon Health and Sciences University, a Parkinson’s Foundation Center of Excellence.

Early Parkinson’s Symptoms

Early signs of Parkinson’s can appear before a Parkinson’s diagnosis is ever made. Non-movement symptoms can begin decades before a diagnosis. Impaired sense of smell occurs in 70 to 90 percent of those living with PD, often precedes other PD symptoms. Licorice, coconut and banana are some smells people with PD have difficulty with, while scents like chocolate, strawberry and onion, are not impacted.

Another common early pre-movement symptom, constipation, can begin around age 40, sometimes preceding a PD diagnosis by 20 years. Erectile dysfunction, REM sleep behavior disorder, depression and anxiety are often also early non-motor PD symptoms. 

Vision Changes

About 14 percent of people with PD experience vision changes including tired eyes, blurred vision, intermittent double vision or difficulties reading and seeing in dim lighting. Optometrists who look closely may discover convergence insufficiency, impaired color perception, blinking irregularities or reduced contrast sensitivity (the capacity to pick out an object from its background). Playing video games may improve contrast sensitivity, but no PD-specific studies have been done. Fitting glasses with prisms can help PD-related double vision. Both blepharospasm (involuntary eye closure) or apraxia of lid opening (inability to open the eye) may benefit from botulinum toxin A (BOTOX®). At-home eye exercises called “pencil push-ups” may help with convergence insufficiency. Talk to your doctor or optometrist about how to perform these exercises, or to discuss vision treatments.

Pain

Pain related to PD is divided into five categories:

1. Musculoskeletal: pain that affects the bones, muscles, ligaments, tendons and nerves. It can occur suddenly and be short-lived or long lasting and can occur in one or several areas. Someone with PD may describe this as aching or burning in their muscles or skeleton.
2. Neuropathic/radicular: chronic pain condition where the body sends pain signals to the brain, not caused by an injury. This sharp pain comes from a nerve or nerve root.
3. Dystonic: sustained or repetitive muscle twisting, spasm or cramp that can occur at different times of day and in different stages of Parkinson’s. Can stem from rigidity and dystonia.
4. Akathisia: causes the feeling of restlessness or inability to be still. An example of this outside of Parkinson’s is Restless Leg Syndrome.
5. Central pain: neurological condition caused by a dysfunction that affects the central nervous system and is resistant to treatment. This pain is usually sharp and burning with no clear cause.

Though muscle relaxers are not usually effective, adjusting PD medications may help minimize “wearing off" episodes. Physical therapy or surgery can improve pinched nerve pain, while BOTOX® injections may improve dystonia.

Autonomic Dysfunctions

Non-motor problems include those with the autonomic nervous system, which controls bodily functions, such as heart rate, blood pressure, sweating, sexual function and both gastrointestinal and urinary function. These can be among the most serious problems for people with PD.

Oral Health Issues

Excess saliva: Experienced by up to 80 percent of people with Parkinson’s, it begins as nocturnal drooling and can progress to heavy saliva outpourings. Drooling isn’t caused by excess saliva; in PD it is due to decreased swallowing frequency and efficiency, as well as tendencies toward an open mouth and stooped posture. While surgery was used in treatment in the past, it is no longer advocated. Hard candy, medications, including sublingual atropine or glycopyrrolate, or BOTOX® injections have all been used in treatment. Discuss options with your doctor.

Dry mouth: Decreased saliva production in PD can cause dry mouth; medications can increase this dryness, raising the risks of cavities and periodontal disease. Artificial saliva products like Biotene®, which contains xylitol and glycerin, can help. Discuss treatments, including medications that increase saliva production, with your doctor or dentist.

Halitosis: Bad breath is common in PD, but rarely discussed. Many factors — dry mouth, inadequate brushing, gum disease, mouth bacteria and not drinking enough fluids — can contribute. Treatment includes adequate cleaning of teeth and mouth and alleviating dry mouth.

Recognizing and Addressing Symptoms

Non-motor PD features may also include sleep disorders, cognitive changes, hallucinations and delusions or weight changes. It’s important to stay abreast of all symptoms, and to discuss treatments with your doctor.

Understanding Medicare can be extremely frustrating for many seniors — there are so many parts involved, so many details that require research and potential changes to health care providers and their services, that some seniors become overwhelmed and find it hard to keep searching for the right coverage. As a caregiver, there are many things you can do to help the process along. From looking online for resources and information to helping your loved one make lifestyle changes that will prevent the need for medical attention, there are many simple ways you can assist in finding the right Medicare plan.

Of course, it is extremely helpful to become familiar with common terms and expressions used in Medicare plans as well as those used by doctors to describe various conditions. If your loved one has Parkinson’s disease (PD), it will be especially important to understand what the terminology is as well as what some of the treatments and medications will be. This will allow you to make sure your loved one has everything they need no matter what their health care requirements are.

Here are a few tips on how to help your loved one understand their Medicare options when you’re a caregiver.

Learn the terms

Understanding Medicare takes time, so do a little reading to learn more about the wording and what it all means. Fortunately, there are lots of resources online that explain what certain parts do and will help you sort out the various — and sometimes confusing — details. These will help you find everything from the dates of the open enrollment period to an explanation of a “coverage gap.”

Take specifics into consideration

Parkinson’s disease is considered an existing health condition that will affect coverage. People with PD may need to make sure a certain doctor accepts their plan. Look for an insurance plan that will meet their specific needs, keeping in mind budget. While some parts of Medicare come at no extra cost, medical insurance includes a copay and add-ons like vision coverage, dental care and prescription medication often require out-of-pocket payments.

Find out important dates

Keep track of important Medicare-related dates. There are specific times of the year for sign-ups and changes to existing plans and anyone who falls outside of those dates are subject to penalties. Take note of this crucial information and keep track of it for your loved one, as it can be confusing for many seniors to understand. It’s also a good idea to make sure your loved one has the type of coverage they need according to their current health status; an Advantage Plan will help cover health care needs that Part A and Part B don’t.. 

Talk to the doctor

Some changes in Medicare plans can affect a senior’s ability to have certain parts of care covered, and sometimes, those changes can cause issues with their chosen doctor. Talk to your loved one’s care provider to make sure they still accept the Medicare plan in question and that no changes need to be made to keep it current.

Helping your loved one understand Medicare is important not just for their present needs, but also for their future. In doing so, you’ll be ensuring that the senior in your life is able to get the care they require for years to come, giving them a great quality of life and keeping their health a priority. Talk to your loved one to get an idea of what their needs are, and keep detailed records related to their Medicare coverage.

Over the next three years the Parkinson’s Foundation will invest more than $50 million to Parkinson’s disease (PD) research and clinical care. At the heart of our research initiatives are scientists and researchers who have received Foundation awards to improve our understanding of Parkinson’s, which will ultimately lead us to a cure.

Gulcin Pekkurnaz, PhD, is a Stanley Fahn Junior Faculty Awardee who is working to understand how aging affects dopamine in Parkinson’s.

Parkinson’s disease develops when the cell’s energy factories, called mitochondria, start to fail in dopamine neurons or nerve cells. Dopamine is a brain chemical messenger that carries information between neurons and helps us to move smoothly. People with Parkinson’s have low levels of dopamine in the brain due to dopamine neurons dying.   

People with Parkinson’s do not develop disease symptoms until later in life. This indicates aging-associated changes are involved in the development of the disease. With aging, both mitochondrial function and cellular metabolism decline. We hope to gain a better understanding of why this happens.

Dr. Pekkurnaz at University of California San Diego received a research grant to study the mitochondria from dopamine nerve fibers in animals. Her goal is to identify what happens to dopamine neuron mitochondria before Parkinson’s symptoms start. To accomplish this, she will develop new technology that will allow us to analyze unique mitochondrial features from dopamine neurons as a function of age.

We hope to gain fundamental insights into how the dopamine neuron energy supply works and they start to fail. These findings can lead to potential drug targets for Parkinson’s.

The Parkinson’s Foundation Stanley Fahn Junior Faculty Award helps ensure promising early career scientists stay in the PD research field. This award provides junior investigators the support they need to develop their own independent funding source.

What’s Next: Reporting Our Findings

Parkinson’s Foundation research awards fund Parkinson’s studies than can span up to three years. Scientists submit yearly progress reports to the Parkinson’s Foundation, and we report findings once the studies have concluded. Stay up to date with our latest research findings at Parkinson.org/Blog.

Since its launch in the late 1960s, carbidopa/levodopa (brand name SINEMET®) is still the most effective Parkinson’s disease (PD) motor symptom treatment. However, it doesn’t address all facets of the disease. Medications to bolster its effectiveness and treat PD-related non-motor symptoms are newly available or just on the horizon.

This article is based on a Parkinson’s Foundation Expert Briefings webinar exploring innovative PD treatments by Rajesh Pahwa, MD, Director, Parkinson and Movement Disorder Division, University of Kansas Medical Center, a Parkinson’s Foundation Center of Excellence.

Pioneering Medicine

It’s an exciting time for PD drug advances. While gene therapy benefits are still being studied, many new medications are on the market or are soon to be. These new treatments are designed to tackle Parkinson’s disease challenges, including:

• Psychosis – hallucinations and delusions.
• Orthostatic hypotension – a blood pressure drop when rising or standing.
• “Off” time – when symptoms and movement difficulties increase.
• Dyskinesia – abnormal, involuntary muscle movement.
• Dementia – memory and thinking declines.
• Falls – PD can cause slowness of movements, increasing falling and other risks.

Current Treatments

Parkinson's Disease Psychosis

PD-associated psychosis can be caused by the disease itself or PD medications. Challenging for people with PD and caregivers, symptoms include confusion, delusions and hallucinations. Report any changes to your medical team.

Pimavanserin (Nuplazid®), newer to the market, is the only approved treatment for PD psychosis. It does not block dopamine or worsen motor symptoms. It can improve hallucinations, delusions, night-time sleep and daytime sleepiness. Side effects include nausea, confusion and hallucinations.

Orthosstatic Hypotension

From 20 to 50 percent of people living with PD experience a significant blood pressure drop upon standing, known as orthostatic hypotension; certain medications can worsen this. This drop can cause lightheadedness or fainting, and other symptoms.

Droxidopa (NORTHERA®) treats lightheadedness. It should not be taken within five hours of bedtime. Side effects include headache, dizziness, nausea, fatigue and high blood pressure when lying down.

"Off"-Time Advancements

Levodopa is synthesized in the brain into dopamine, making it key to PD symptom management. But several factors can interfere with steady, accurate dose delivery. When medication is not taken on time, or absorption is delayed, freezing and other sudden and debilitating motor symptoms can occur. These newer medications can help tackle “off” periods.

Carbidopa/Levodopa Enteral Suspension (Duopa™)

Duopa™ therapy, a newer carbidopa/levodopa treatment, can benefit people with advanced PD who respond well to levodopa and experience three or more “off” hours daily. It’s delivered in gel form (called enteral suspension). Duopa™ users must first have surgery to place a tube in their intestine that is later connected to a pump that delivers Duopa™.

Safinamide (XADAGO®)

Safinamide tablets (XADAGO®) are an add-on treatment for people with Parkinson’s taking carbidopa/levodopa and experiencing “off” times. Safinamide is a monoamine oxidase B (MAO-B) inhibitor that can reduce “off” times up to 55 minutes a day, without dyskinesia. Interactions include other MAO-B class drugs, certain antidepressants and the cold medicine dextromethorphan. Anyone taking a PD medication should talk to their doctor and pharmacist about potential drug interactions.

On-Demand Therapy

Levodopa Inhalation (INBRIJA™)

The levodopa inhalation powder INBRIJA™ is an add-on drug for “off” periods in people taking carbidopa/levodopa. Administered via inhaler, it can be used up to five times a day, improving “off” symptoms as soon as 10 minutes and lasting up to 60 minutes. This can improve symptoms for people with decreased gut motility while waiting for oral carbidopa/levodopa to take effect.

Amantadine ER capsules (GOCOVRI®)

This is the only medication to treat dyskinesia and “off” time in people with PD taking carbidopa/levodopa. It must be taken before bedtime and provides control of dyskinesia upon awakening and throughout the day. It can cause hallucinations and lightheadedness. This medication is different from immediate-release amantadine and amantadine ER tablets (OSMOLEX ER™) which are not approved for dyskinesia or “off” time.

IncobotulinumtoxinA (XEOMIN)

More than 50 percent of people with PD can have excessive drooling, causing skin breakdown around the mouth, odors, embarrassment or choking. Two injections on the face, every 3-4 months of XEOMIN, can manage symptoms.

Future Therapies

Sublingual Apomorphine

Apomorphine is administered through injections under the skin. Sublingual apomorphine, dissolved under the tongue, can relieve “wearing off” episodes for people with Parkinson’s disease in 15 minutes and lasts up to 90 minutes. Side effects can include nausea, sleepiness, and dizziness.

Rimabotulinumtoxin B (MYOBLOC®)

Rimabotulinumtoxin B is currently approved for dystonia and used off-label for drooling. It is undergoing trials to treat drooling. Side effects include dry mouth, mild swallowing difficulty, mild chewing weakness and saliva thickness changes.

Adenosine A2 Antagonist: Istradefylline

A group of brain circuits called the basal ganglia play a role in causing PD symptoms. The basal ganglia have adenosine A2A receptors that are located next to dopamine receptors. Scientists believe that activating the dopamine receptor or blocking the adenosine A2 receptor can improve PD symptoms.

Istradefylline, an adenosine A2A receptor antagonist shows mild motor symptom fluctuation improvements. Approved for use in Japan, Istradefylline has also received U.S. FDA approval.

Subcutaneous Apomorphine Infusion

Available in Europe, subcutaneous apomorphine treatment offers a less invasive motor fluctuation treatment option. A small delivery tube placed under the skin is connected to an apomorphine-filled pumping device. It can reduce daily “off” time and possibly dyskinesia by reducing needed levodopa dose. Those with hallucinations and dementia might not be candidates.

Subcutaneous Carbidopa/Levodopa Pump

Two companies are currently developing pumps for continuous under-skin carbidopa/levodopa therapy to reduce “off” times and motor symptom fluctuations. The pumps can be used around the clock and don’t require surgery.

Carbidopa/levodopa extended release

New tests are underway for extended-release carbidopa/levodopa therapy to reduce “off” times and motor symptom fluctuations.

• Accordion Pill™, Carbidopa/Levodopa (AP-CD/LD) maker, will begin its Phase 3 clinical trial of new delivery technology. The Accordion Pill slowly releases treatment in the stomach for more steady absorption.
• IPX203, an investigational extended-release oral carbidopa/levodopa formulation that increases “on” time, is currently enrolling participants in its Phase 3 clinical study.

Opicapone

Experimental opicapone is a COMT (catechol-o-methyl transferase) inhibitor. This drug class can extend levodopa benefits. Available in Europe, opicapone reduces “off” time for people with PD experiencing levodopa effectiveness fluctuations.

This Parkinson’s Awareness Month, we asked our Parkinson’s disease (PD) community to share their keys to Parkinson’s with us. We received hundreds of keys to living well with Parkinson’s!

Whether you are living with PD, are a caregiver or a healthcare professional, thank you for sharing your tips that make life a little easier. We will be posting your keys at Parkinson.org/Blog throughout the year but check out our top 10 keys submitted by YOU.

Exercise

“I listen to audiobooks and love good thrillers. I tease myself into exercising by allowing myself the satisfaction of hearing what happens next only when I’m exercising.”
- Patricia

“Create a playlist for walking. My symptoms get worse towards the end of long walks as I tire. By creating a playlist of songs with a good strong walking beat, the muscle memory kicks in and helps my body finish the walk strong instead of dragging one heel and not having one arm swing.”
- Fred

“For me, I have been blessed to be part of the Rock Steady Boxing (RSB) family for the last 3 plus years. Our coaches encourage us to push ourselves to continue to improve our strength, balance, movements, stamina and endurance. We have class 4 times a week and what a great and supportive new family of friends we have in each other! If you had told me that I would be doing a boxing workout at age 71 for an hour 3-4 times a week, I probably would have laughed. Rock Steady Boxing has given me a whole new positive outlook on my Parkinson's.”
- Wayne

Medication

“I use a black container to put all my husband’s medications in when I get them ready for him to take. I used to use little clear plastic cups that fruit snacks come in, but since most of his pills are white or light colored it was sometimes for him to see if he took them all. Then I found some black sauce cups from an Italian restaurant and he said he could see the pills much better against the black.”
- Susan

“Planning. I am the live-in caregiver for my mom with PD. I set aside a few hours one day a month to set up her pills in four, seven-day containers. That way in case something comes up with her or me at least we have her pills ready. I also set alarm timers in her phone and mine for her pill times. Such a big help!”
- Megan

Daily Living

“My key to living well with Parkinson’s is a metronome. When I get up in the morning, I have trouble walking because of freezing issues. It is very frustrating. There are ways to trick your brain into walking, but the best thing I have found is a metronome. The tick, tick, tick helps me to get going. Now I don’t want to carry a metronome around and as they say, ‘there’s an app for that.’ I have it on my phone and it is my key to get my morning moving!”
- Joyce

“I have rather severe tremors and eating gets pretty messy. I find that if I put my plate of food on top of a large bowl, the distance from plate to mouth is much reduced, which makes more food stay on the spoon or fork during that journey. It is a very small thing but for me, it makes a big difference.”
- Carole

“Use supermarket gift cards so you don't have to sign for a credit card or fumble with paper money and coins.”
- Sandra

“To decrease my leg pain/stiffness when I go to sleep, I do an Epsom salt soak. Heat the water as hot as you can stand it (without sustaining a burn). Add two cups of Epsom salts (there are some that are infused with lavender) and 1/2 cup baking soda. To enhance the experience, light a candle and/or play soothing music. Soak for 20 to 30 minutes.”
- Moises

"Since my hands are weak, I use a Waterpik, face scrubber, button hook, electric toothbrush and hair dryer holder to help me get dressed and out the door faster. My best tip is using a seat belt extender in my car so that I can buckle up with my right hand. These things are small but make life so much easier. Also, it's important to have a 'happy place' and parrots are mine!"
- Martha

Many people with advanced Parkinson’s disease (PD) suffer from gait (walking) dysfunction, freezing of gait and postural instability. These symptoms can cause falling, resulting in a multitude of injuries, a loss of personal freedom, caregiver stress and a reduction in the quality of life (Pirker & Katzenschlager, 2017; Samotus, Parrent, & Jog, 2018). Medications, such as levodopa, rarely helps with these specific motor symptoms, while deep brain stimulation (DBS) results are limited and unpredictable for these particular symptoms. The fact is, current PD medications, therapies or surgical procedures do not effectively address this debilitating unmet need. This lack of options might be changing, due to an intervention called spinal cord stimulation (SCS).

Surgically implanted, SCS is a device that alters nerve activity by sending a low-voltage electrical current to select areas of the spinal cord. These voltage settings are adjustable post-implantation, which allows for personalized optimization. SCS is currently used to treat people with chronic back and nerve pain, as well as for neuropathic pain, such as diabetic neuropathy, and chemotherapy or radiation induced neuropathy. Exploring its usefulness for people with PD has just begun.

Recently published in the journal of Movement Disorders, a study titled, “Spinal Cord Stimulation Therapy for Gait Dysfunction in Advanced Parkinson's Disease Patients” (Samotus et al., 2018), a six-month pilot study recruited five PD participants with advanced PD. These participants were chosen based on convenience. Participants were an average age of 71 with average disease duration of 14 years. Participants who had a stroke (or any other neurological diseases) and moderately severe parkinsonism in the context of unstable medication treatment (Samotus et al., 2018) were not included in the study. All five participants underwent mid-thoracic spinal cord stimulation surgery and a dorsal spinal cord stimulator was implanted in the epidural space (near the lower back).

This study evaluated SCS efficacy by clinical evaluation and objective gait analysis before and after surgery. A 20-foot gait detection mat equipped with pressure sensors — a relatively new technology (Muro-de-la-Herran, Garcia-Zapirain, & Mendez-Zorrilla, 2014) — was used to measure various features of gait such as step length, stride width, stride velocity, step time, stance, swing, and percentage of time one or two feet are on the ground. To measure freezing of gait, a timed sit-to-stand test was used, as well as an automated freezing detection program that measured changes in foot pressure.

The study also evaluated different frequency and pulse width combinations via gait analysis multiple times 1-4 months after surgery. Eleven frequency and pulse width SCS combinations were tested. Of note, the freezing questionnaire, the Unified Parkinson’s Disease Rating Scale (UPDRS) motor items, Activities-specific Balance Confidence Scale (ABC), and Parkinson’s Disease Questionnaire (PDQ-8) were given to all five participants at every visit.

Results

• Six months post-implantation, there was an average improvement of 33.5%, in the UPDRS motor score, 26.8% in the FOG questionnaire and 71.4%, in the ABC score.
• Significant improvement in all participants’ confidence to complete daily activities, especially around and outside the house, occurred in week six and improvements were maintained following week 10, resulting in an average improvement of 71.4% in week 24 compared to before the SCS implantation.
• The number of freezing episodes captured on the gait mat dropped quickly from an average of 16 before surgery to zero six months after surgery, per study participant, on levodopa and off stimulation.
• Stride velocity significantly improved by 42.3%, mean step length improved by 38.8% and the time in seconds for a participant to arise from a chair to a standing position improved by 50.3%.
• By week 24, two of the five participants were able to walk without assistance whereas they needed it before surgery, and three of the five participants reported that their activities of daily living were now only moderately affected by gait dysfunction, whereas they were severely affected before surgery.
• One participant reported no longer needing to use his wheelchair and was solely using a walker by the end of the study,
• No adverse effects were reported.

What Does This Mean?

First presented at the 21st International Congress of Parkinson’s Disease and Movement Disorders, this is the first study to use objective gait technology to assess SCS efficacy for people with advanced PD.

Ranging from significant improvement in all study participants’ confidence in performing activities of daily living, to one of the participants no longer needing a wheelchair, to sustained improvements in gait, the pilot study results are encouraging. Stride velocity improved by 42.3%, average step length improved by 38.8% and the time in seconds for a participant to stand up from a chair improved by 50.3%. Perhaps most impressive was the reporting of zero freezing episodes six months after SCS surgical implantation with no adverse effects.

Further, SCS technology proved to be personalized, as doctors were able to adjust technology after implantation in order to provide the optimal therapeutic value. Unlike most surgical procedures, SCS is reversible. Also, important to note, SCS runs on batteries — some are rechargeable, and others last up to 5 years (NIH, 2019).

Although it is a small pilot study, it nonetheless demonstrated that SCS may offer some significant therapeutic value for people with advanced PD. A larger and longer clinical study is warranted to see if these rather remarkable preliminary results can be replicated.
