An overview is given over etiology and prognosis of cerebral ischemias until the age of 40. In a time period of 19 years, 168 patients were diagnosed with cerebral ischemia until the age of 40 (91 females, 77 males). The most frequent etiology is premature atherosclerosis in patients with vascular risk factors (up to 50%). Cardiogenic embolism is responsible for 1 to 34% of the cases: cardiac valve diseases and endocarditis being the most frequent sources. In 2 to 19% a vasculitis is diagnosed. While infectious arteritis is especially frequent in countries of the third world, immunovasculitides are common in Europe and the USA. Noninflammatory vasculopathies include spontaneous or traumatic dissection, fibromuscular dysplasia and vascular malformations. A migrainous stroke is especially frequent in female smokers with intake of oral contraceptives. During pregnancy both sinus thrombosis and arterial ischemia occur. Hematologic causes for ischemia are polycythemia, thrombocytosis and genetic diseases (sickle cell anemia, AT3-deficiency). Cerebral ischemia may occur in connection with the ingestion of ergot-derivates. The prognosis of cerebral ischemia in young adults is better than in older stroke-patients.
