Subjective Cognitive Complaints and Objective Cognitive Impairment in Parkinson's Disease.

ABSTRACT:

Background and purpose

Subjective cognitive complaints (SCCs) are very common in patients with Parkinson's disease (PD). However, the relationship between SCCs and objective cognitive impairment is still unclear. This study aimed to determine whether SCCs are correlated with objective cognitive performance in patients with PD.

Methods

Totals of 148 cognitively normal patients, 71 patients with mild cognitive impairment (MCI), and 31 demented patients were recruited consecutively from a movement-disorders clinic. Their SCCs and cognitive performances were evaluated using the Cognitive Complaints Interview (CCI) and a comprehensive neuropsychological battery.

Results

The CCI score increased with age, duration of PD, and depression score, and was inversely correlated wit
