A stroke or cerebrovascular accident is defined as the abrupt onset of a neurologic deficit that is attributable to a focal vascular cause. Thus the definition of stroke is clinical and laboratory studies including brain imaging are used to support the diagnosis1 . As reported by Frederic2 , 11.3% of cases of stroke gave history of diabetes when compared with 2% in the general population. The incidence of diabetes was found to be twice as high in patients admitted to hospital with any type of stroke than in patients with other neurologic diseases. The increased risk of stroke in diabetes and the increased prevalence rate of stroke in diabetes as compared to the general population was confirmed by a study done by Wolf et al3 . Diabetics as well as patients with stress hyperglycaemia have severe stroke and these patients are associated with poor prognosis. The mortality rate from stroke in diabetics was twice that of the general population4. Glucose tolerance also deteriorates with age5 . Multivariant studies also show that blood glucose is a significant predictor of death6 . Diabetic macrovascular diseases including coronary heart diseases, stroke, and peripheral vascular diseases were common causes of morbidity and mortality among people with diabetes mellitus7 . As reported by several studies, it was found that hyperglycaemia in non-diabetic patients after acute stroke is a stress response reflecting more severe neurological damage. However, it is also
