[Prognosis of transient ischemic accidents disclosing infarction].

In a prospective study, thirty six out of 175 consecutive patients (21%) with transient ischemic attack (TIA), had cerebral infarction on CT-scan. This group of patients differed from the group without cerebral infarction by a higher age, a longer duration of neurological deficit, a greater frequency of neurological history, vertebro-basilar TIAs, cephalagia and, cardiac arrhythmia, and by a higher 2-year mortality rate. Due to their difference in etiological factors and prognosis, TIAs with cerebral infarction on CT-scan should be differentiated from those without cerebral infarction.
