Abstract: This study was carried out in Al-Thawrah General Hospital and Al-Gamhori Teaching Hospital in Sana'a, in the period from 1st January to 30th June 1998. The study aimed to determine the pattern, presentation, risk factors, predictors of outcome of stroke in Yemeni patients, and to estimate the accuracy of clinical diagnosis of subtypes of stroke. Data analysis was done using IBM compatible personal computer SPSS/PC Software Package. The significance of association between individual variables and outcome and subtypes of stroke was determined with Chi-square test (P greater than 0.5). Male to female ratio was 1.6:1 Age ranged between 19-99 years. The majority of patients were in their 5th and 6th decade of age; one to two decades earlier than in developed countries. Motor weakness was the most presenting features, mainly as hemiplegia (92 percent). The major risk factors were hypertension (34.1 percent), diabetes mellitus (12.5 percent), cardiac diseases (17.5 percent), smoking (64.8 percent) and khat chewing (69.3 percent). On the first day of admission 69 (78.4 percent) patients were unable to walk, 6 (6.8 percent) could walk with help and 13 (14.8 percent) independent. Stroke subtypes by C.T. scan in 76 patients were ischemic stroke in 58 percent, intracerebral haemorrhage in 31.5 percent, subarachnoid haemorrhage in 3.9 percent and not determined in 6.6 percent. Within a period of 30 days of follow up, 26.1 percent of patients died, 62.5 percent discharged with residual deficit and 11.4 percent completely recovered. Depression of consciousness, severity of hemiplegia and papilloedema were significantly related to mortality. Accuracy of clinical diagnosis for all patients was 71.8 percent. Thus C.T. scan is needed for more accurate distinction between hemorrhagic and ischemic stroke .
