[Dementia evaluated by means of a mini-mental status examination. Clinical neurologic patient material]
Abstract:
The mini-mental state examination (MMSE) was administered to a neurological patient material with various disorders. The test was found useful for detecting cognitive impairment. The test did not differentiate reliably between different causes of cognitive impairment. To detect dementia a cut-off score of 25 or less yielded 100% sensitivity and 97% specificity. The validity of the DSM-III-diagnostic criteria for dementia, primary degenerative dementia and multi-infarct dementia was high. The modified ischemic score (MIS) seemed to be of limited value in differentiating primary degenerative dementia from multi-infarct dementia.
