Abstract: Type 2 diabetes is one of the fastest growing public health problems in both developed and developing countries. It is estimated that the number of diabetic people in the world will double from 171 million in 2000 to 366 million in 2030. Cardiovascular disease accounts for more than 70% of total mortality among patients with type 2 diabetes. The associations of type 2 diabetes and hyperglycemia with the risk of stroke have been assessed by a number of prospective studies and the results are inconsistent. Some, but not all studies have identified type 2 diabetes or hyperglycemia as an independent risk factor for stroke among women. Most of the previous studies have focused on total or ischemic stroke alone because type 2 diabetes is not a prominent risk factor for hemorrhagic stoke. Our review based on the scientific evidence confirms that type 2 diabetes may increase the risk of stroke.
