Strokes in young adults are relatively uncommon and have more various and diverse possible causes or risk factors than elderly strokes. We evaluated 222 patients aged 15-45 years who were admitted to our hospital during 1989-1991 under diagnose
of
cerebral infarction, intracerebral hemo9rrhage, and subarachnoid hemorrhage. These age groups comprised 13.0% of all patients admitted for stroke.
Cerebral infarction was diagnosed in 47 patients who had atherosclerossi (hypertension, diabetes mellitus, hyperlipidemia etc), heart disease (valvular heart disease, atrial fibrillation, cardiomyopathy, endocarditis), meningitis. Moyamoya
disease,
leukemia, alcohol, migraine, Cushing's syndrome. Takayasu arteritis, polycythemia etc. as their underlying diseases.
Intracerebral hemorrhage was diagnosed in 85 patients who had hypertension, ruptured arteriovenous malformation, ruptured aneurysm. Moyamoya disease, leukemmia, tumor, pregnancy etc. as their underlying diseases. Subarachnoid hemorrhage was
diagnosed in
90 patients; the causes were ruptured aneurysm, ruptured arteriovenous malformation, and Moyamoya disease.
From the above results, we confirmed young adult strokes were related to various underlying diseases and extensive studies were needed for diagnosis of causative diseases.
