Vascular diseases of the brain are the second reason of the death and the first cause of morbidity and disability worldwide. In tropical areas stroke has some particular features related to the nature of torrid zones. There are some special causes of the stroke, mainly infectious, although some of them are non-infectious. The most important etiologies are malaria, tuberculosis, cysticercosis, syphilis, and Chagas’ disease. The mean age of the patients with stroke in tropical areas seems to be less than that in developed countries, and the disease is more prevalent in younger adults.
