Brief Summary
The goal of this study is to investigate neurophysiologic tests that have the potential of serving as screening tools for Parkinson's disease. These neurophysiologic tests will be administered to individuals with Parkinson's disease and parkinsonian syndrome and validated against a healthy control population. Specifically, this study will look at changes in motor function, cognitive function, handwriting, speech, and olfactory function in individuals with Parkinson's disease, individuals at risk for Parkinson's disease and healthy controls.

PD/PS
Interventions
This study will evaluate a profile of neurophysiologic tests for potentially predictive signs of PD or PS in individuals with PD or PS, those who may be at risk for PD or PS and in a population of individuals without parkinsonian symptoms or any other neurologic conditions. In addition, the study will evaluate serum samples for changes in proteins or metabolites that may be indicators of early changes associated with Parkinson's disease or parkinsonian syndrome.
Eligibility Criteria
These neurophysiologic tests will be administered to individuals with Parkinson's disease and parkinsonian syndrome and validated against a healthy control population.
You may qualify if:
- As a participant with PD or PS:
- Age \>21
- Clinical diagnosis of PD or PS (at least two of the three cardinal symptoms: resting tremor, rigidity, bradykinesia) and a clinical response to dopaminergic therapy
- For Healthy Control:
- Age \>21
You may not qualify if:
- As a participant with PD or PS:
- Any other concomitant neurologic condition likely to interfere with handwriting, use of the computer, or other motor tasks tested in this study (e.g. stroke, demyelinating disease, visual loss)
- For Healthy Control:
- Any indication of parkinsonism on examination
- Any other concomitant neurologic condition likely to interfere with handwriting, use of the computer, or other motor tasks (e.g. stroke, demyelinating disease, visual loss)
