Cognitive Testing Online in Parkinson's Disease

Deep Cognitive Endophenotyping of Parkinson's Disease: A Platform Development and Pilot Study

This is a feasibility and pilot study. Though large-scale online neurocognitive testing is increasingly being done in psychiatry, there are no such efforts in Parkinson's research. Thus a large part of this pilot study will be to demonstrate feasibility and reliability, and use this experience to develop a feasible protocol for ongoing research. The specific short-term objectives are:

1. To establish the feasibility of performing large-scale deep cognitive phenotyping using online cognitive testing.
2. To demonstrate that online neurocognitive testing is valid and reliable in a smaller sample of locally recruited participants tested both in-lab and online.

Inclusion Criteria:
