Do you have moderate Parkinson's disease with motor symptoms? Are you over 45 years old? You may be able to participate in a research study to find out if a new treatment involving surgery can help with your symptoms. Compensation provided.

Do you have problems with your thinking or memory? Or a parent or sibling with dementia? If so, we'd like you to join this registry about the brain and Alzheimer's disease. In return for providing us with a little bit of your health history and background, we will connect you with researchers doing studies you can join, without obligation. Many studies pay a stipend and some offer a possible treatment.

In this study, we want to compare a new drug for multiple sclerosis (MS) with a drug that is already being used. We want to see how the new drug works and if it might be a better option for treating MS.

The purpose of this study is to see if batoclimab is safe and helps people with chronic inflammatory demyelinating polyneuropathy (CIDP), an autoimmune disorder. Batoclimab is also known as IMVT-1401. Batoclimab is injected under the skin (subcutaneously) and targets the immune system.

Are you between 18 and 45 years of age and diagnosed with multiple sclerosis, without MS relapses within the past year? Are you currently prescribed with MS medication? If so, you may be able to participate in a research study examining whether a switch to a high-efficacy medication- Ofatumumab, would work better for you than your current treatment.

Have you or a family member been diagnosed with Parkinson's Disease? Would you be interested in helping researchers learn more about Parkinson's by giving a blood or saliva sample? If so, you may be eligible to participate in a research study that will utilize genetic testing to provide you more information about the possible roles of your genes in your diagnosis.

In this study, we want to understand whether we can use non-invasive brain stimulation to treat non-moto symptoms like autonomic nervous system dysfunction and depression in people with Parkinson's disease.

The purpose of this study is to identify and genomically-characterize individuals with genetically unexplained neurodevelopmental disorders, such as epilepsy. The overarching goal is to provide patients with improved information about the underlying genetic basis of their disorder and illuminate novel genetically-defined treatment approaches in the future.

Do you have probable Dementia with Lewy Bodies (DLB), Mild Cognitive Impairment with "high likelihood" DLB, or Parkinson's Disease Dementia (PDD)? You may be able to participate in an observational study to track your disease progression and promote future research.

The purpose of this study is to test the efficacy of ZX008 for kids and adults with CDD. We will measure this based on a decrease in motor seizures and using the Clinical Global Impression- Improvement rating scale.
