ABSTRACT: Objective
Cognitive impairment is a common nonmotor symptom among individuals with Parkinson's disease (PD). Although cognitive impairment generally develops progressively, individuals with PD-associated mild cognitive impairment (PD-MCI) may revert to being cognitively normal (CN), which is referred to as PD-MCI reversion. Previous studies are inconsistent in whether PD-MCI reverters are at greater risk for PD-MCI recurrence relative to CN individuals. Even less is known about how PD-MCI reverters compare with CN individuals or PD-MCI nonreverters in terms of neurodegenerative biomarkers. The authors examined group differences (CN, PD-MCI reversion, and PD-MCI nonreversion) in cerebrospinal fluid (CSF) markers of Alzheimer's disease (AD), including amyloid beta, tau (total [t-tau]
