title: Clinical features and long-term follow-up of patients with reversible ischemic attacks (RIA).
abstract: The clinical features of 102 cases with transient attacks due to cerebral ischemia were evaluated, and 94 out of 102 cases were followed for an average of 6 years. 1) The clinical study makes comparisons between two groups of patients grouped under the somewhat new definition of Reversible Ischemic Attacks (RIA): classical Transient Ischemic Attacks (TIA) and Stroke with Full Recovery (SFR), in which a complete recovery took place over a longer period, on the average 3 weeks. 2) SFR constitutes the 34.31% of the total cases with transient ischemic episodes. In the carotid district the onset was more frequently gradual in SFR than in TIA and aphasia more frequent in TIA than in SFR. Multiple attacks prevailed in TIA over the SFR group. The definition of transient attack due to ischemia is discussed. 3) Completed strokes occurred in 11 cases (11.7%) with RIA. Hypertension and cardiac disease were significantly frequent in cases with subsequent stroke. The conclusion was reached that TIA is a symptom, not a pathological state, and TIA should be considered an important symptom but not a specific harbinger of completed stroke.
