title: Validity and metric of MiniMental Parkinson and MiniMental State Examination in Parkinson's disease.
abstract: The MiniMental Parkinson (MMP) has been derived from the MiniMental State Examination (MMSE) for the screening of cognitive impairment in Parkinson's disease by adding subtests that were focused on executive and visuo-spatial impairment more than on memory or language deficits. In this multicenter study, the psychometric and validity properties of the MMP have been evaluated in 69 cognitively intact and 52 cognitively impaired patients with Parkinson's disease, classified according to their performance at the Dementia Rating Scale. The MMP showed better metrics and convergent validity, and higher screening ability. However, its performance was not fully satisfying in terms of data distribution, coefficient of variation and specificity, and Receiver Operating Characteristic curves did not show clear cut superiority of either scale at their best sensitivity-specificity trade off. The MMP seems to be slightly preferable to the MMSE only at a cut off that favours sensitivity with respect to specificity, for screening purposes. The test is simple and quick, but has limitations in terms of validity.
