Physical activity is an important component of the management of Parkinson’s disease and is shown to mitigate cognitive decline among patients with moderate disease, said Dr. Mantri and colleagues. “Exercise levels in de novo and early disease may influence risk of future cognitive decline; early disease also presents an opportunity for early intervention and possible disease modification,” Dr. Mantri said.
Physical activity levels in early disease are known to be low, but the effects of activity on cognition are currently unclear. To assess the relationship between physical activity and cognition, Dr. Mantri and colleagues examined patients with Parkinson’s disease who were enrolled in the prospective Parkinson’s Progression Markers Initiative (PPMI) cohort. At annual study visits, participants completed the, a validated self-reported questionnaire assessing household, leisure, and work activities over the previous 7 days. The researchers used a linear mixed-effects model to compare rates of change in the according to PASE scores; covariates included age, sex, Unified Parkinson’s Disease Rating Scale (UPDRS) part III score, and baseline MoCA.
A total of 379 patients completed at least one PASE questionnaire over the course of the study. PASE scores in this cohort have been previously described (
