Development and Preliminary Validation of ORCA-PD, an Online Rapid Cognitive Assessment for Parkinson Disease: Mixed Methods Study

Category	Detail
Condition	Parkinson's Disease (PD)
Key Mechanisms	Cognitive decline associated with PD, including challenges in task switching, working memory, and visuospatial abilities.
Target Population	Individuals with Parkinson's Disease, including those with and without mild cognitive impairment (MCI).
Care Setting	Remote, self-administered online cognitive assessment.

ORCA-PD is a web-based cognitive screening tool tailored for Parkinson's Disease.
Designed to enhance accessibility and scalability for cognitive assessments.
Evaluated for feasibility and preliminary validity against the Montreal Cognitive Assessment (MoCA).
Can distinguish between neurotypical individuals and those with PD, as well as between PD-non-MCI and PD-MCI cohorts.
Higher completion rates for ORCA-PD compared to traditional in-person assessments.

Consider potential biases in self-reported data and the need for validation against established tools.

Patients with Parkinson's Disease, including those with mild cognitive impairment.

ORCA-PD allows for cognitive assessments without the need for in-person visits, addressing accessibility issues.

Encourage the use of self-administered cognitive assessments for patients with mobility challenges.
Ensure that cognitive assessments are tailored to the specific cognitive profiles of PD.
