title: Dementia of the frontal lobe type: report of the neuroimaging and neuropsychological results of a case study.
abstract: We report the behavioural abnormalities, neuroimaging, and neuropsychological results of a 62-year-old patient, i.p., who shows a clinical profile that fulfils all characteristics of dementia of frontal lobe type. The patient has been followed up over 5 years with psychometric testing. Comparing her cognitive profiles across examinations, her performance was substantially unchanged apart from behavioural disturbances and performance on frontal tasks which showed a progressive worsening. MRI finding evidenced marked ventricular enlargement, prevalent frontal atrophy and hypertrophy of the genus of corpus callosum. SPECT investigation showed a considerable reduction of cerebral blood flow in the mesial parts of the frontal lobes, in the lateral surface of the right fronto-parietal lobe, and hypo-perfusion in the right thalamic area. The results are discussed with reference to the features (clinical and neuropsychological) which distinguish different profiles of dementia.
