Fourty-nine patinets with focal neurological deficits lasting for less than 24 hours (TIA), were followed up for 6 to 169 months averaging 65 months. During the follow-up period 9 cases (18.4%) developed stroke and 13 cases (26.5%) died. Among the latter 2 died of cerebral infarction. In relation to subsequent stroke, clinical features and angiograms of the TIA-giving artery were analysed. Angiographic findings in 12 patients with non-embolic cerebral infarction preceded by TIA were also studied. Subsequent stroke developed more frequently in patients with more than 10 episodes of TIA and with arterial stenoses of 50% and over in diameter.
