[Tardy epilepsy--clinical analysis of 292 cases]

292 cases of tardy epilepsy were studied. 242 cases of them had undertaken CT scanning, these results were compared with the results of EEG the patients with local seizures or local abnormalities on EEG had a significantly high abnormality rate on the CT scans. In 114 cases (39%) the causes of the seizures were due to head injury, cerebrovascular disease, encephalitis or meningoencephalitis, brain tumor, or excessive alcoholic drinking. The authors were of the opinion that although no relation could be found between the history and abnormal findings on CT scans, the patients with tardy epilepsy should undertake CT scanning early.
