The mini-mental Parkinson's (MMP) as a cognitive screening tool in people with Parkinson's disease.

Background: Cognitive decline is common in Parkinson's disease (PD) but may not be adequately identified by the mini-mental state examination (MMSE), which is better suited to Alzheimer's disease. The mini-mental Parkinson (MMP) examination is a cognitive screening tool designed in French specifically for PD. We aimed to establish the validity and reliability of the English language version of the MMP compared with the MMSE.
