Abstract: Cognitive impairment is one of the most common non-motor symptoms of Parkinson's disease (PD) and a major influencing factor on patients' daily living ability. Mild cognitive impairment (MCI) is a cognitive state between normal aging and dementia, and the living capability of MCI patients relatively remains. MCI often occurs in PD, with its clinical features presenting as the impairment in working memory and (or) attention, executive function, language ability, memory and visuospatial function. Here we try to depict the general picture of PD-MCI from the view of epidemiology, pathology, clinical presentation, imaging and diagnostic criteria.
