Abstract: Background:The relationship between statins and cognition in Parkinson’s disease (PD) is poorly understood. Objectives:Analyses were performed to determine associations between statin use and cross-sectional and longitudinal cognitive performance in PD. Methods:Neuropsychological tests, medication logs, and ratings of functional abilities were collected from 313 PD participants longitudinally. Results:At baseline, statin users (SU; N = 129) were older, more likely male, and had shorter PD duration than non-statin users (NSU; N = 184). In Cross-sectional analysis, SU performed better on global cognition, Trails B, semantic fluency, and phonemic fluency tasks. Rate of long-term global cognitive (Dementia Rating Scale-2 and MoCA) decline was significantly less in SU.
