title: [Mental competence and neuropsychologic impairments in demented patients].
abstract: The study aim was to examine if neuropsychological tests and clinical dementia scales identify incompetent patients with dementia. Eighteen demented outpatients (ICD-10: F00-F03) underwent psychiatric examination, neuropsychological testing, and formal (MacArthur Competence Assessment Tool Treatment, Hopkins Competency Assessment Test) and clinical assessment of competence. Clinical dementia scales but not neuropsychological testing correlate with formal and clinical assessment of competence in patients with dementia. Our results do not support a neuropsychological model of competence assessment. However, in cases with poor results in clinical dementia scales, clinicians should assess the patients' competence in more detail. It remains open which is the best and ethically grounded methodology for competence assessment.
