The GBA Multimodal Study in Parkinson's Disease
This study aims to understand why some people with a specific gene change, called a GBA mutation, are more likely to get Parkinson's disease and experience memory problems. Researchers will use advanced brain scans to look at certain brain chemicals and proteins in people with this gene change, both with and without Parkinson's. They will also use a special computer test to see if typing patterns can reveal early signs of the disease. The goal is to provide new insights into Parkinson's, especially for those with the GBA mutation, and to find new ways to spot the disease early.
At a glance
What is this study about?
This research study is trying to understand more about Parkinson's disease, especially for people who have a particular gene change known as a GBA mutation. We know that if you have this GBA mutation, you might have a higher chance of developing Parkinson's. Also, if you do get Parkinson's with this mutation, you might be more likely to have memory and thinking problems.
The study wants to look closely at what's happening in the brains of people with the GBA mutation. Researchers will use special kinds of brain scans, like PET scans, to measure important brain chemicals such as acetylcholine and dopamine, and to see if a protein called tau builds up. These are all things thought to be involved in Parkinson's and memory issues. They are also using a unique computer typing test to see if the way someone types could be an early sign of movement problems linked to Parkinson's.
By doing this, the researchers hope to learn more about how Parkinson's disease starts and develops, particularly in people with the GBA mutation. This knowledge could help in finding better ways to diagnose the disease earlier, perhaps even before symptoms fully appear, and could also lead to new treatments. It might also help us understand Parkinson's more generally, even for those without the GBA mutation.
Key takeaways
- Researchers are studying the link between a GBA gene change and Parkinson's disease.
- They will use special brain scans (PET, MRI) and computer typing tests.
- The goal is to understand how Parkinson's starts and progresses, especially with the GBA mutation.
- Findings could lead to earlier diagnosis and better future treatments.
- This study is for research, not a cure, and involves several visits and tests.
Who may be eligible?
This study is looking for volunteers between 18 and 80 years old who have a specific change in their GBA gene. This includes people who have Parkinson's disease *and* the GBA gene change, as well as people who have the GBA gene change but *do not* yet have Parkinson's symptoms.
However, there are some reasons why you might not be able to join. For example, if you have other brain or nerve conditions, or if you have metal implants in your body (like a pacemaker), you wouldn't be able to participate. If you get very anxious in small spaces (severe claustrophobia) or can't stop certain Parkinson's medications, you also wouldn't be suitable.
Also, if you are currently taking medications that affect a brain chemical called acetylcholine, you would not be able to take part.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you between 18 and 80 years old?
- Do you have a GBA gene mutation (with or without Parkinson's symptoms)?
- Do you not have other serious neurological conditions?
- Do you not have metal implants that would stop you from having an MRI?
- Are you comfortable with enclosed spaces for scans?
What does participation involve?
If you join this study, you will have several appointments. First, you'll have a check-up with the study team and do a typing test on a computer. After that, you'll have a brain MRI scan and three special types of brain scans known as PET scans. These PET scans involve a small amount of a safe tracing substance being given to you to help the scanners see specific things in your brain.
Each PET scan will look at different things: one at a protein called tau, one at the brain chemical acetylcholine, and another at dopamine. You will also need to give a blood sample for further tests. The study does not specify the total duration or number of visits, but it involves these various assessments.

Common questions
What is a GBA mutation?
It's a change in a specific gene called GBA that can increase the risk of developing Parkinson's disease and experiencing memory problems.
What are PET scans?
PET scans are special brain scans that use a small amount of a safe, traceable substance to show what's happening inside your brain, like brain chemical activity or protein buildup.
Will this study cure my Parkinson's?
No, this is a research study to understand the disease better, not a treatment. It aims to gather information that could help develop new treatments or diagnostic methods in the future.
Is the typing test difficult?
The study aims to observe your natural typing patterns, not to test your typing speed or skill. It's a technology-based assessment for research purposes.
Will I get paid for taking part?
The study information typically does not mention payment, but it's a good question to ask the research team directly when you consider joining.
