概要: We assessed the anatomical findings and language impairment of eleven right-handed patients with fluent aphasia followin g frontal lesion(5 men, 6 women:aged 42~79, mean 64.5 years). All the patients showed fluent speech from the onset, and excellent repetition. However, they showed difficulty in word finding and impairment of language comprehension. We administerd all the patients Western Aphasia Battery, 50 words pointing tasks using line drawings selected from among common Japanese words for language training for aphasics, and Token test. Anatomical analysis was done on the basis of brain CT and/or MRI. The patients were devided into three groups on the basis of the impairment of comprehension of single words. One group had no impairment of comprehension of single words, another showed slight impairment and the other showed severe impairment. Each group had different lesion site. We concluded as followings:first, lesions in the Broadmann area 6 and 9 produce impairment in comprehension of single words and the lesion extended to anterior to Broca’s area worsen the impairment. Second, any lesions in the left frontal lobe can produce impairment of comprehension of complex sentences. 続きを見る

概要: Among the various approach to dementia disease, neuropsychological approach have a specific role to reveal the mechanism of the disturbances of the patients. The basic way of neuropsychological approach demands the detailed observation of what the patient can and cannot do and find out the core of the disturbance. Regarding the main purpose for the diagnosis, it is most important to pick up the findings which indicate the lesion sites or the specific and reliable signs for a certain disease. Herein some of the represented and useful focal signs are introduced. Regarding the parietal lobe lesion, constructional disturbance can be useful to distinguish Alzheimer's disease and Simple dementia. The occipital lobe signs such as Balint's syndrome and visual agnosia, indicates Alzheimer's disease or posterior cortical atrophy. As to temporal lobe, various language disturbances are specific signs, for example Gogi aphasia is found only in the cases of Pick's disease or post herpes encephalitis. Anarthria is specific focal sign of the posterior part of left inferior precentral gyrus, and limb clumsiness (limb-kinetic apraxia) is related to the lesions of pre and post central gyrus. Neuropsychological approach can be useful not only for the diagnosis, but also for promoting the way to find out the clinical characteristics related to the diseases. 続きを見る
