Transient ischemic attacks (TIA) are episodes of abrupt beginning, consisting of subjective or & objective neurological dysfunction of short duration, with complete recovery of neurological function in the & course of 24 hours. With this definition, the authors carried out a retrospective study of ISO patients suffering & from ischemic infarct in the brain in the territory of the middle cerebral artery. Thirty-eight percent of the & patients had had TIAs before their cerebral infarct. The symptoms, in order of frequency, were motor, sensory & deficits, alterations of speech and vision. Most of the patients had a definite cerebral infarct, occurring one & month after the last TIA; the symptoms of both processes were remarkably similar.The authors studied the angiographic characteristics, pharmacological and toxic antecedents, and & associated diseases in these patients. The study indicates that TIA may be the first manifestation of cerebral & vascular disease.
