Read our Parkinson Disease research guide →Researchers are building a database of people with familial Parkinson's disease—that is, Parkinson's that runs in families. By collecting medical information, blood samples for genetic testing, and answers to questionnaires about lifestyle and environment from patients and their relatives, the study aims to understand why some families are affected by Parkinson's and what factors (genetic, environmental, or both) play a role.
Parkinson's disease that runs in families has different patterns and causes than cases that appear randomly. By studying families together, researchers hope to identify the genetic and environmental factors that contribute to familial Parkinson's, which could eventually lead to better prevention and treatment strategies.

You would visit the study center where researchers would perform neurological exams and ask you to complete several questionnaires about your symptoms, sleep, mood, and lifestyle (including questions about smoking, drinking, and exposure to pesticides or heavy metals). You would also have a blood sample drawn for genetic testing. Your relatives who are part of the study would undergo similar assessments. The study is ongoing, so participants may be asked to return for follow-up visits.
