Global Genetics Study Reaches 50% Enrollment Milestone of 7,500 Participants

Researcher transferring vials

Genetics is a key step in solving Parkinson’s disease (PD). Understanding how and why Parkinson’s and genetics fit together is a mystery the Parkinson’s Foundation is looking to solve through our landmark study, PD GENEration: Mapping the Future of Parkinson’s Disease. The Parkinson’s Foundation is excited to announce that we are accelerating the path to solving the puzzle of genetics and Parkinson’s through reaching a significant study milestone of providing genetic testing and counseling to 7,500 participants — 12 months ahead of the study recruitment timeline.

“Ensuring that the entire Parkinson’s community — including the 90,000 individuals expected to receive a PD diagnosis this year — has access to their genetic status is as critical as ever,” said James Beck, PhD, chief scientific officer for the Parkinson’s Foundation. “Every PD GENEration participant plays a part not only in their own personal discovery but also in feeding results to researchers which will advance future research.”

Halfway to its goal, the study is on track to provide genetic testing and counseling at no cost to 15,000 people with Parkinson’s, which will establish the largest Parkinson’s genomic dataset in North America.

“I cannot underscore enough how relevant this landmark study is. Our current and rapidly expanding knowledge of this complex disease highly suggests that the likely ‘first cure’ to be discovered will be specific to a genetic mutation for PD, which will then serve as a stepping stone for the ultimate cure for the general PD population,” said Hubert Fernandez, MD, Head of Movement Disorders at Cleveland Clinic and co-chair of the Parkinson Study Group.

In 2022, we expanded the study and made access to genetic testing possible for people with Parkinson’s in all 50 U.S. states, Puerto Rico, the Dominican Republic and Canada. In the next two years, we will introduce PD GENEration to Israel and other countries, bringing a new level of diversity and depth to Parkinson’s genetic research, which can lead to greater insights. So far, 22% of participants represent historically marginalized racial and ethnic groups.

The study continues to expand its reach with the addition of testing sites and collaborations with clinicians in historically excluded communities. This includes a partnership with Morehouse School of Medicine, to make the study more accessible for Black and African American persons in Atlanta, GA. Similarly, the Foundation extensively engages Hispanics and Latinos and provides genetic counseling in English and Spanish, a first of its kind for a study of this scale. Roughly 11% of Latino and Hispanic participants have a 17% genetic link to PD.

“Through the expansion of the PD GENEration study to more populations, we are bringing diversity to genetics data. In turn, this will accelerate the pace of research to help all people with Parkinson’s, regardless of where they live.”     — Carlos Singer, MD, professor of neurology at the University of Miami Miller School of Medicine

The study’s data are analyzed in real-time by the Parkinson’s Disease Gene Curation Expert Panel (GCEP), an international working group of genetic experts focused on neurodegenerative diseases formed by the Foundation within the NIH-funded Clinical Genome (ClinGen) Resources. Alongside the Parkinson's Foundation, Roy Alcalay, MD, leads the study as principal investigator.

Currently, investigators have found that 14% of participants have a genetic form of PD — a significant observation compared to the long-standing estimate of 10%.

Artificial Intelligence Study Detects Parkinson’s from Breathing Patterns

Parkinson's Foundation Science News blogs

Parkinson’s disease (PD) is the fastest growing neurological disease in the world. Currently, there is no single test or biomarker that can diagnose PD or monitor disease progression. However, a new study utilizing artificial intelligence may change the way we track Parkinson’s.

A lot like a warning system, a biomarker (short for biological marker) is used to help measure what is going on in the body. For example, the A1C blood test can help detect prediabetes. Early detection, treatment and expert care is vital to maintaining quality of life.

The challenge, so far, has been the lack of biomarkers for early PD diagnosis. Usually, PD is only diagnosed years after early signs appear— when movement symptoms (such as tremor, rigidity, and difficulty walking) are present. However, a new study may have found an early biomarker for PD.

In a groundbreaking study published in the journal Nature Medicine, “Artificial intelligence-enabled detection and assessment of Parkinson's disease using nocturnal breathing signals” (Yang et al., 2022), the authors developed an artificial intelligence (AI)-enabled system that could reliably:

  1. Wirelessly identify people who have PD from their breathing patterns during sleep
  2. Accurately assess people’s PD disease severity
  3. Track PD progression over time
Xray scan of lungs

Study authors point out that the relationship between Parkinson’s disease and breathing is documented in various studies. Further, the authors note that this breathing link has been reinforced by more recent PD studies that go a step further, reporting that degeneration in the brainstem helps control breathing, issues of respiratory muscle weakness, and sleep breathing disorders. According to the study, “Since breathing and sleep are impacted early in the development of PD, we anticipate that our AI model can potentially recognize individuals with PD before their actual diagnosis” (Yang et al., 2022, p. 2207).

Artificial intelligence is a highly sophisticated technological tool that mimics human-like thinking to analyze enormous amounts of data, find patterns, make predictions and recommendations. Researchers designed an AI-based system for detecting PD, predicting its severity, and tracking disease progression over time using nocturnal breathing. The system can take the breathing input signals in two different ways:

  1. Using a breathing belt placed in the person’s chest or abdomen, or
  2. Using a Wi-Fi-like router that sends a low radio signal placed somewhere in the room. The signals transmitted are reflected off the person’s body and further analyzed.

Regardless of the signal source (belt or radio waves), once collected, the AI-based model processes the signals using a neural network. This network uses a series of instructions, called algorithms, that tells a computer how to transform the enormous amounts of data into useful information. Importantly, the person’s breathing patterns are automatically fed to the neural network to assess their PD status and its severity. No state-of-the-art equipment is required, and no special training is needed for the person with PD or caregiver.

To test their AI technology, researchers used a large and diverse dataset that included data from 11,964 nights of sleep with more than 120,000 hours of nighttime breathing among 757 people with PD and 6,914 control subjects (people without Parkinson’s). They sought to determine whether the AI diagnostic findings (from both belt and radio wave users) could compare to standard PD tests, such as the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS). PD diagnosis was evaluated using: 1) diagnosis made by a clinician using the MDS-UPDRS PD rating scale, 2) the AI model developed by the authors.

Results

The AI system can:

  • Predict the presence or development of PD with 90% accuracy
  • Track PD progression and estimate PD severity as well as the MDS-UPDRS (PD rating scale used by doctors)
  • Provide an objective, non-invasive, at-home assessment of PD while a person is asleep, without touching the body
  • Combine measurements from multiple nights to achieve optimal test accuracy
  • Provide nightly and weekly measurements in a person’s home, that tests such as the MDS-UPDRS would not be able to capture
  • Eventually be deployed in the homes of individuals at high risk for PD (e.g., those with the LRKK2 gene mutation) to passively monitor their status and provide feedback to their provider

What does this mean?

With impressive accuracy, this AI system was able to successfully detect, assess and track disease severity of PD in a home setting by extracting breathing from either a wearable belt or from radio waves that bounce off a person's body while they sleep.

This AI model also provided initial evidence that a touchless, non-invasive system may be a useful biomarker for early detection or risk of PD. Further, according to the study authors, this method is low-cost, and would bring accessibility to PD care to people who live in rural areas not near medical centers that specialize in PD care. The system could be mailed to the person’s home, used for a few nights, and returned for evaluation.

Meet Two Parkinson’s Researchers Studying Key Protein in PD

Shahmoradian and Bellomo headshots

The Parkinson’s Foundation is proud to invest in research initiatives that aim to improve our understanding of Parkinson’s disease (PD), work toward new treatments and, ultimately, a cure.

Two of our current researchers are investigating what happens when a protein integral to the development of Parkinson’s — called alpha-synuclein — begins to accumulate in the brain, and whether this early accumulation can lead to earlier diagnosis of Parkinson’s. Both studies could lead to important breakthroughs in diagnosing PD and understanding how PD develops and progresses.

Sarah Shahmoradian, PhD: Learning About Early-Stage Accumulation of Alpha-Synuclein in the Parkinson’s Brain

Sarah Shahmoradian, PhD, of the University of Texas Southwestern Medical Center, received a Parkinson’s Foundation Stanley Fahn Junior Faculty Award to study early-stage build-up of a protein called alpha-synuclein in the brain.

In Parkinson’s, the alpha-synuclein protein misfolds into an abnormal shape, causing the protein to clump together. These protein deposits have been linked to the loss of brain cells. In addition, alpha-synuclein deposits have been correlated with cognitive decline in PD.

Prior research has largely focused on the late stages of alpha-synuclein accumulation. However, much is still not known about the critical early events that cause a single abnormal alpha-synuclein molecule to recruit and transform additional molecules to become toxic. This leads to build-up and spreading to other brain cells.

Dr. Shahmoradian will apply state-of-the-art, high-resolution imaging techniques to uncover the molecular structure of alpha-synuclein within the brain cells, and to study how alpha-synuclein contributes to the disease process in Parkinson’s. This research will define where and how alpha-synuclein buildup first occurs within human brain cells.

MY PD STORY: Sarah Shahmoradian, PhD

“Results from these studies will fundamentally advance our understanding of how Parkinson’s disease develops. They could thereby inform on novel therapeutic strategies.”

Giovanni Bellomo, PhD: Creating A Diagnostic Test Could Detect Parkinson’s Earlier

Giovanni Bellomo, PhD, of the University of Perugia in Italy, received a Parkinson’s Foundation Postdoctoral Fellowship for Basic Scientists to improve the usefulness of a group of testing techniques called seed amplification assays (SAAs) in the early diagnosis of Parkinson’s disease.

Currently, there is no single test to diagnose PD, and movement disorders specialists often rely on the presence of movement symptoms to make a diagnosis. However, by the time someone with PD shows symptoms, the disease is already past its early phase. Early detection would allow earlier disease-modifying treatment, which could potentially benefit people with Parkinson’s.

One of the earliest known changes that occurs in brains affected with PD is the emergence of alpha-synuclein deposits. Tests like the seed amplification assays are used to detect a biomarker (a biological molecule that is a sign of disease). Having a biomarker for Parkinson’s could lead to earlier diagnosis and can improve outcomes for people living with PD.

Seed amplification assays have been successfully used to detect alpha-synuclein pathological changes in the cerebrospinal fluid (CSF) of people with Parkinson’s. However, several factors limit their use in clinical practice. To overcome the existing limitations, Dr. Bellomo will study whether the olfactory mucosa (i.e., nasal cells) can be used in SAAs. Collecting these samples is easily achieved by using a swab to scrape small amounts of olfactory mucosa from inside the nose. This non-intrusive test would represent a breakthrough in Parkinson's diagnosis, as no such test currently exists.

Second, Dr. Bellomo also aims to improve current CSF SAAs by making them capable of estimating the amount of disease-causing alpha-synuclein present in CSF samples. This is a key step toward testing treatments against pathological forms of alpha-synuclein.

2022 Postdoctoral Fellowship 

Utilizing Lampreys to Explore New Drug Target for Parkinson’s

Cristina Roman-Vendrell, PhD, from the Marine Biological Laboratory is utilizing an invasive species from the Great Lakes to further Parkinson’s disease (PD) research. She received a Parkinson’s Foundation Postdoctoral Fellowship for Basic Scientists to conduct a study using the sea lamprey (a jawless vertebrate fish) that will work to discover how buildup of the protein alpha-synuclein affects synapses — the contacts between brain cells. The findings could lead to new targets for Parkinson’s medications.

“This research will provide insights into the earliest features of PD,” Dr. Roman-Vendrell said. “It has the potential for identifying treatments that can improve synaptic function. This will help in the development of therapies to slow or halt PD progression.”

Parkinson’s is characterized by the misfolding of a protein called alpha-synuclein, which causes the protein to form deposits (or “build-up”) in the brain. In addition to limiting the brain’s ability to produce dopamine, this abnormal build-up of alpha-synuclein at synapses is linked to thinking changes and dementia in PD. This build-up appears to occur early in the disease — before other signs of nerve cell degeneration.

About Alpha-Synuclein: When it comes to Parkinson’s disease, the protein called alpha-synuclein plays a key role. This protein begins to form sticky clumps in neurons (cells in the brain) in people with PD. Over time, the clumping kills healthy neurons and impairs the brain’s ability to produce dopamine, leading to Parkinson’s symptoms and ultimately a diagnosis.

This makes synapses an excellent target for treatment. However, not much is known about how alpha synuclein builds up at synapses. This slows down research and the ability for scientists to develop new treatment strategies.

Electron microscope image of a sea lamprey synapse

Dr. Roman-Vendrell will inject PD-derived alpha-synuclein into the synapses of lampreys to see how it leads to synaptic dysfunction. Lampreys have large, visible neurons, making them used a lot in neuroscience research. Due to their large reticulospinal neurons, researchers can microinject antibodies and proteins to disrupt specific molecular targets at synapses. “We can then use high-resolution imaging [see image] for detailed analyses of synaptic structure and function,” Dr. Roman-Vendrell said.

For more than 10 years, the Marine Biological Laboratory has been levering the unique features of the sea lamprey's giant synapses and implementing them as a model for studying how alpha-synuclein impacts synapse structure and function. “To our knowledge, our lab is the first to utilize the lamprey synapse model to investigate impacts of PD on synapses,” said Dr. Roman-Vendrell.

“Our lampreys come from the Great Lakes, where they are an invasive species,” she said. “Scientists use them as models for neuroscience and developmental biology, as well as evolutionary biology and ecology.”

Dr. Roman-Vendrell will also investigate whether selected alpha-synuclein inhibitors can improve synapse function in PD. Of her Parkinson’s Foundation grant award, she said, “Many years ago, a dear family friend was diagnosed with Parkinson’s disease. It was heartbreaking to see her deteriorate and unable to do even basic things on her own. As a scientist, I was motivated to pursue neuroscience research that may help us find treatments for this terrible disease. It is a great honor to receive this award and to know that people with PD may benefit from the outcomes of my research.”

2022 Stanley Fahn Junior Faculty Award  

Improving Deep Brain Stimulation to Improve Motor Symptoms in Parkinson’s

Coralie de Hemptinne, PhD, of the University of Florida, a Parkinson’s Foundation Center of Excellence, received a Parkinson’s Foundation Stanley Fahn Junior Faculty Award to study a way to improve deep brain stimulation (DBS) therapy for Parkinson’s disease (PD). She aims to develop a process that would automatically program DBS devices.

With DBS, a surgically implanted device delivers electrical pulses to brain structures involved in movement. DBS can be an effective treatment for movement symptoms in people with Parkinson’s.

It is challenging and time-consuming to customize a DBS device for each person. Though current technology makes it possible to program the device to avoid side effects, this is complex given the nearly infinite number of possible ways to program the device.

Automated methods to program the device are needed. This will reduce the complexity and improve the efficiency and effectiveness of DBS, allowing for more long-term benefits. One approach is to develop an algorithm, or set of rules, that automatically identify the best way to program the device. The rules would be based on signals of brain activity affected by DBS.

“Developing these algorithms could increase the effectiveness of DBS and improve the ease of treatment. It will remove the ‘trial and error’ process of doctor-managed stimulator changes. It could ultimately improve the quality of life for patients with Parkinson’s disease.” - Dr. de Hemptinne.

Dr. de Hemptinne will enroll 40 people with Parkinson’s undergoing implantation of DBS to treat their movement symptoms. The range and frequency of the stimulation will be varied to study their effects on brain signals. Based on the findings, she will develop an algorithm that automatically chooses these factors. Electrical signals in the brains of study participants will be recorded both during DBS implantation surgery and in-clinic. This will allow Dr. de Hemptinne to determine whether the algorithm is effective in choosing DBS settings.

Of her Parkinson’s Foundation grant award, she said, “Receiving this award is a great honor for me. It is especially meaningful to get this grant as a new independent principal investigator. It will allow me to develop my research projects and contribute to building my laboratory. It will also foster stronger collaborations with my colleagues. This award will be a launching point for my career to get bigger awards and grants and establish my research program.”

2025 Impact Award 

Highlighting Alpha-synuclein Clumps in PD with Small Molecule Trackers 

Tracking Parkinson’s disease (PD) progression is challenging. Doctors currently rely mostly on how a person’s symptoms change over time. Because those symptoms vary from person to person and can fluctuate from day to day, this approach can make it difficult to evaluate whether treatments are truly helping. 

For other brain diseases like Alzheimer’s, scientists have developed small molecules that can attach to disease-related protein clumps and make them visible on brain scans such as PET (positron emission tomography). These imaging tools allow researchers and clinicians to see where harmful proteins are building up in the brain, providing a clearer, more objective way to track disease progression and test therapies. 

Sarah Shahmoradian, PhD, recipient of a Parkinson’s Foundation Impact Award, is exploring whether a similar biomarker tag could work for Parkinson’s. Working with collaborators at Massachusetts General Hospital, a Parkinson’s Foundation Center of Excellence, Dr. Shahmoradian is studying a specially designed small molecule that appears to bind strongly and selectively to misfolded alpha-synuclein clumps—the abnormal protein deposits that are a hallmark of Parkinson’s disease. 

“We aim to provide the first atomic-resolution view of how a promising small-molecule PET tracer binds to alpha-synuclein fibrils in human Parkinson’s brain,” says Dr. Shahmoradian. 

Inside the brain, misfolded alpha-synuclein proteins can form dense clusters that disrupt how nerve cells work. Evidence suggests these toxic protein forms may even spread from one neuron to another, contributing to the gradual worsening of symptoms in PD. A molecule that can label these alpha-synuclein clumps could allow researchers and physicians to visualize Parkinson’s pathology directly in the living brain—an advance that could transform diagnosis, treatment monitoring and research. 

From her lab at the University of Texas Southwestern Medical Center in Dallas, Dr. Shahmoradian will use high-resolution imaging methods — developed through her earlier Parkinson's Foundation-supported research— to see precisely how this new molecule attaches to alpha-synuclein fibrils. Understanding this interaction at the molecular level will help scientists fine-tune the tracer for future clinical imaging. 

The next step is to adapt the molecule so it glows under the microscope. By applying it to neurons grown in the lab that model Parkinson’s disease, or to slices of PD brain tissue, Dr. Shahmoradian and her team hope to track where alpha-synuclein clumps appear and how they move inside cells. If successful, this work will demonstrate that the molecule can serve as a powerful diagnostic and research tool for Parkinson’s. 

“This award gives me the opportunity to pursue a line of research I see as essential for advancing how we detect and monitor Parkinson’s disease,” said Dr. Shahmoradian. “This research will help accelerate the development of clinically useful biomarkers for early diagnosis and therapeutic monitoring in PD.”

Learning About Early-Stage Accumulation of Alpha-Synuclein in the Parkinson’s Brain

Sarah Shahmoradian, PhD, of the University of Texas Southwestern Medical Center, received a Parkinson’s Foundation Stanley Fahn Junior Faculty Award to study early-stage build-up of a protein called alpha-synuclein in the brain.

“Results from these studies will fundamentally advance our understanding of how Parkinson’s disease develops,” Dr. Shahmoradian said. “They could thereby inform on novel therapeutic strategies.”

Parkinson’s disease (PD) is characterized by the misfolding of the alpha-synuclein protein into an abnormal shape. These shapes clump together to form sticky deposits in the brain that disrupt the brain’s ability to produce dopamine — and are connected to cognitive decline and dementia. This build-up appears to occur early in the disease.

About Alpha-Synuclein: When it comes to Parkinson’s disease, the protein called alpha-synuclein plays a key role. This protein begins to form sticky clumps in neurons (cells in the brain) in people with PD. Over time, the clumping kills healthy neurons and impairs the brain’s ability to produce dopamine, leading to Parkinson’s symptoms and ultimately a diagnosis.

Prior research has largely focused on the late stages of alpha-synuclein deposits. However, much is still not known about the critical early events that cause a single abnormal alpha-synuclein molecule to recruit and transform additional molecules to becoming toxic. This leads to build-up and spreading to other brain cells.

Ongoing research is focused on where alpha-synuclein first begins to accumulate in the brain. Previous studies have used high-resolution imaging to analyze alpha-synuclein that is either chemically extracted from the human brain or artificially produced. However, researchers still do not know if the molecular structure of the toxic form of alpha-synuclein can be found in a natural state within brain cells.

Dr. Shahmoradian will apply state-of-the-art, high-resolution imaging techniques to uncover the molecular structure of alpha-synuclein within the brain cells, and to study how alpha-synuclein contributes to the disease process in Parkinson’s. This research will define where and how alpha-synuclein buildup first occurs within human brain cells.

Of her Parkinson’s Foundation award, she said, “Being granted this generous support from the Parkinson’s Foundation cements my commitment to continue research in Parkinson's disease. Through receiving this award from an organization intimately linked to those affected by PD, I feel a heightened sense of personal responsibility and urgency in executing my research.”
