简要总结
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.
详细描述
One of the greatest challenges in Parkinson's research is the identification of individuals who are at risk or have early Parkinson's disease (PD) or parkinsonian syndrome (PS). Subtle signs that do not meet the diagnostic criteria for PD may occur during this period.
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.
Each study participant will be scheduled for a 90 minute study visit.
This visit may include the following procedures:
