Feasibility and Optimization of a Cognitive Intervention for Parkinson Disease

Cognitive impairment is common in Parkinson disease (PD) and is a significant source of disability and reduced quality of life. Existing rehabilitative interventions, which focus on cognitive process training, have not been successful in mitigating its negative functional consequences. We have developed a client-centered cognitive strategy training intervention to enable people with PD to work around their cognitive deficits and maintain their functional performance. This study is an exploratory case series to assess aspects of its feasibility. Specifically, we will assess participant responsiveness to the intervention (acceptance, engagement, adherence), and we will track logistical information (e.g., scheduling). We will also administer an exploratory outcome measure of treatment effect to gain preliminary evidence on the effect of the intervention on self-identified cognitive performance problems. This information will guide modifications and enhancements in preparation for future clinical trials.
