ABSTRACT
The aim of the present work was to identify risk factors in different ischemic stroke subtypes, namely; cortical, large subcortical and lacunar infarctions and to correlate between clinical presentation and radiological findings in each of the previous stroke subtypes. Eighty one patients were included in this study. According to computed tomography and/or magnetic resonance imaging results, the patients were subdivided into cortical, large subcortical and lacunar infarct groups. Risk factors were studied according to Stroke Risk Assessment Form. The clinical picture was studied according to Mini-Mental Scale and Canadian Neurological Scale. In cortical infarctions, atrial fibrillation and high mean platelet count were more common. In large subcortical infarctions, oral contraceptives were more commonly used. Pure lacunar infarctions were more related to positive history of hypertension, and high mean systolic blood pressure. As regards Mini-Mental Scale; orientation, registration and total score were lower among cortical infarctions. There were no statistically significant difference between the three groups as regards the Canadian Neurological Scale; mentation score, total motor score with or without comprehension deficit. There are differences between different stroke subtypes as regards clinical picture and risk factors
