Dementia in Thai stroke survivors: analysis of 212 patients.
A cross-sectional designed study was done at Siriraj Hospital from 1990 to 1994 to determine the prevalence of dementia in Thai stroke survivors. Two hundred and twelve Thai stroke (both hemorrhage and infarction) survivors (132 males and 80 females) were enrolled in this study. The mean age of the study group was 62.78 (S.D. 11.12) years with the mean duration of stroke suffering of 2.09 (S.D. 2.74) years. All patients were screened for depression by using Thai Geriatric Depression Scale and patients with Alzheimer disease were excluded from the study. The Thai Mental State Examination (TMSE) is a standard test used in this study to identify stroke patients with dementia. Seventy stroke patients (33.02 per cent) scored below 23 points (cut-off point for dementia) and considered as dementia. Forty patients (18.88 per cent) scored below 20 points and were considered as having severe dementia, 30 patients (14.15 per cent) scored between 20-22 points (classified as mild to moderate dementia). Fifty-eight patients (27.36 per cent) were in the borderline group as they had TMSE scores between 23-25 points. Eighty four patients (39.62 per cent) of stroke survivors were determined as nondemented as their TMSE scores were over 25 points. The items of cognitive function tests in TMSE which were severely impaired in demented group were recall and calculation whereas registration and attention were relatively unaffected. Orientation and language were moderately impaired in the demented group.(ABSTRACT TRUNCATED AT 250 WORDS)
