    ORCA-PD is a web-based cognitive screening tool designed to assess cognitive impairments in individuals with Parkinson's Disease.

  • 2

    The tool addresses challenges of accessibility, scalability, and specificity in traditional cognitive assessments for Parkinson's Disease.

  • 3

    In a study, 112 participants completed ORCA-PD, demonstrating its feasibility and higher completion rates compared to in-person assessments.

  • 4

    ORCA-PD was validated against the Montreal Cognitive Assessment, showing its ability to distinguish between neurotypical individuals and those with Parkinson's Disease.

  • 5

    The development of ORCA-PD aims to enhance early detection of cognitive decline in Parkinson's Disease without increasing motor demands.
