Abstract:
Objective To explore the characteristics of event-based prospective memory (EBPM) and time-based prospective memory (TBPM) impairments in patients with Parkinson's disease (PD). Methods EBPM and TBPM were examined in 87 PD patients and 85 healthy controls. And both of them were divided into two groups: aged group (≥60 years old) and non-aged group (＜60 years old). Results (1) The scores of EBPM were significantly lower in aged PD patients and non-aged PD patients than in age-matched control groups [(2. 5±0. 4) vs. (5.8± 1.3),(3.9±2.4) vs. (6.3±1.5), both P＜0. 01]. There were no significant differences in the scores of EBPM between aged PD patients or non-aged PD patients and their age-matched control groups [(3.6±0.5) vs. (3.8±0.8), (4.8±0.9) vs. (4.9±0.9), both P＞0.05]. (2)The Hoehn-Yahr grade in PD patients was significantly correlated with scores of EBPM, but not with scores of TBPM.Conclusions The patients with PD have an impairment in EBPM, but not in TBPM. The impairment of EBPM may be related to the disease severity of PD.
