Healthy people needed for Parkinsonism research study

Healthy individuals at least 40 years old are needed to participate in a research study at Johns Hopkins Green Spring Station in Lutherville, Maryland. The study is looking at the differences in cognition (thinking) and biospecimens (body fluids) between healthy people and individuals diagnosed with parkinsonism.

Eligible individuals must:

  • Be fluent English speakers
  • Not have any family history (1st or 2nd degree relatives) with Parkinson's disease (PD), Alzheimer's disease (ALZ), or progressive supranuclear palsy (PSP)
  • Be 40-89 years old
  • Not have a severe deformity of the lower spine

Individuals will be asked to complete memory questionnaires, have some body fluid collections done, and undergo a brief exam by the study neurologist. The study involves an annual one-day visit, which takes place once every two years, for a total of three years, and participants are compensated $150 each visit. All meals and travel expenses are covered by the study.
