Abstract
Patients (80) with transient ischemic attack (TIA) were examined via computer tomogram (CT) and EEG. In 53 patients a normal CT was found and in 32, a normal EEG. In the patients with pathological CT findings (27) a significantly lower number of normal EEG (22) was seen. Further subdivision of the 27 pathological CT findings revealed 12 patients with hypodense areas (infarctions) and 15 patients with an atrophy only. A normal EEG was significantly rarer in patients with a hypodense lesion (2) and in those with atrophy (3), focal EEG changes being significantly more frequent. EEG findings facilitate the etiological linking of an atrophy to an ischemic stroke, especially when EEG follow-up examinations are included in the diagnostic procedure.
