Mini-Mental Parkinson: first validation study of a new bedside test constructed for Parkinson's disease.
We have developed a brief screening test aimed at identifying cognitive disorders in Parkinson's disease. The Mini-Mental Parkinson derives from the Mini-Mental State Examination of Folstein. It includes seven ordered subsections, with a total score of 32. A pilot study was conducted in 50 community-dwelling parkinsonian patients, in order to establish its metrological qualities. Comparisons were made with a neuropsychological battery including several tests widely used in the assessment of specific cognitive disorders in Parkinson's disease. The correlations between the Mini-Mental Parkinson and each component of this battery were substantial, especially for the performance subtests of the WAIS-R (r = 0.62 to 0.72), the Stroop test (r = 0.65) the 15-objects test (r = 0.64), the word fluency (r = 0.63) and the Odd Man Out test (r = 0.61). The validity of each subtest of the Mini-Mental Parkinson was adequate except for one, based on a word choice, which requires a modification in French before definitive use. The test-retest reliability was high (r = 0.84). There was a significant difference in the mean scores in cases with confusional event (22.4), even without current signs of dementia, compared with patients with no such history (27.2). In conclusion, this brief test is suitable for assessment of parkinsonian patients.
