[Electroencephalographic changes in reversible ischemic cerebral infarction].

In 246 patients with reversible ischaemic neurological deficit eeg investigations were carried out. The eeg curves were compared with the clinical symptoms, with reference to the region of vascularisation, intensity of neurological signs, and time of regression of the clinical symptoms. The obtained results demonstrated, that in 246 EEG records made during acute phase of the disease 110 were normal, and from 136 abnormal records the majority (85 curves) showed only small changes. We have noticed that eeg records with no or small changes we met in patients whose clinical symptoms disappeared during 10 days from the beginning of the disease, where with the neurological syndrome lasting for a longer period, the number of the records with more severe changes was considerably larger. In our opinion, an eeg record showing no, or slight degree of pathology may suggest a reversible character of the ischaemic stroke.
