Sleep correlates of trait executive function and memory in Parkinson's disease.

ABSTRACT:

Background

Sleep disturbance and cognitive impairment are correlated in non-diseased populations, but their association in Parkinson's disease (PD) is uncertain. Prior studies examining measures of cognition in relation to sleep have used either self-report or actigraphically measured sleep and have produced conflicting findings.

Objective

In this descriptive study, we correlated measurements of sleep in PD patients derived from the gold-standard measurement, in-lab polysomnography, with an extensive battery of cognitive measures. We hypothesized that poorer sleep would be related to relatively more impaired cognition.

Methods

Idiopathic PD patients (n = 34) completed a cognitive battery encompassing three broad domains (executive function, immediate memory and delaye
