RESUMO
Objective:To compare the cognitive functions between elderly of Shanghai, Hong Kong and San Diego.Method:104 elderly in Shanghai was evaluated by the Chinese version of Mattis Dementia Rating Scale (DRS)and mini-mental state examination (MMSE), the results were compared with that of 104 persons in Hong Kong and 150 elderly participants in San Diago.Result:Compared with Hong Kong participants, Shanghai participants performed significantly higher on one item, but there were significantly differences in five items between Shanghai participants and the San Diego participants which age and education were matched.Conclusion:Some DRS subscales or individual items may be susceptible to cultural differences.
RESUMO
Objective: To analyze auditory verbal memory impairment after isolated stroke lesions in subcerebral structure. Methods: Auditory verbal memory function was examined in 25 normal elderly and 83 patients at 20th day after their admission to hospital for acute cerebrovascular disease with non-aphasiaand solitary lesions as identified by cranial CT or MRI. Results: Test findings suggested patients with stroke of internal capsule-basal ganglia, cerebellum and pons lesion have processing impairments of recent memory and subjective organization which are related to concentration and arousal levels. Conclusion: Stroke of subcortical regions such as lesions of thalamus,internal capsule-basal ganglia,cerebellum and pons may induce memory impairments with unique impaired cognitive coding modalities.
