MoCA and MMSE subitems’ sensitivity across the PD-cognitive spectrum

A sample of PD patients was administered MMSE (Mini-Mental State Examination) and MoCA (Montreal Cognitive Assessment). The aim of the study is to determine which MoCA and MMSE subitems are more sensitive in detecting cognitive abnormalities in patients with PD across the entire cognitive spectrum, ranging from PD with normal cognition (PD-NC), mild cognitive impairment (PD-MCI) and dementia (PDD). The findings could shed new light on the development of a PD-specific brief cognitive scale with good psychometric properties.
