Abstract:Prospective memory(PM) plays an important role in human’s daily life. Its impairment may significantly affect the correct execution of common daily activities. Patients with Parkinson’s disease (PD) present with cognitive impairments in many aspects. Some recent studies indicate that PM is impaired early in individuals with PD. These patients are selectively impaired in time-based PM, event-based PM or different components of PM. The deficit might be related to dysfunction of prefrontal lobe. In this paper, we reviewed the studies on the characteristics and physiological mechanism of PM, the characteristics of PM in PD patients, and possible underlying physiological mechanism. The further studies will certainly help the daily life and improve quality of life for PD patients.
