The cause and prognosis of strokes in people under 50 years.
A study of 192 personal cases of completed stroke, reversible ischaemic neurological deficit (RIND) or transient ischaemic attack (TIA) in patients aged 10-49 years seen between 1961 ad 1979 inclusive is reported. Three died acutely; 189 were followed for up to 15 years. The main cause of the initial event was atheromatous or hypertensive vascular disease. Of the 90 patients whose initial event was a completed stroke 19(21%) developed a second stroke, whereas only 4 of the 78 patients with TIA suffered a stroke later. In the entire series there were 6 cardiac deaths and one from mesenteric thrombosis during the follow-up period. The risk of stroke following TIA is less in persons under 50 years than in the older age group. The risk of a second stroke following an initial stroke depends on whether or not there is evidence of vascular disease. In the absence of such evidence the risk is small; in the presence of evidence it is high, being of the order of 20%.
