Healthy volunteers needed for parkinsonism research study

Healthy adults age 40 or older are needed for a clinical research study that requires three annual visits to a Johns Hopkins neurology clinic at the Green Spring Station campus (Lutherville, Md.). The study team is seeking adults without any cognitive impairment (e.g., learning or memory difficulties) and no personal or family history of Parkinson's disease or progressive supranuclear palsy (PSP). Each annual visit takes up to eight hours and includes memory questionnaires, health history, a blood draw, urine sample, and lumbar puncture by a JH neurologist. Participants can earn up to $450 for completing the study; free parking and meals are provided.

Interested volunteers are welcome to contact the study manager, AJ Hall, directly at with any questions or to determine eligibility.
