Clinico-Statistical Studies on Epilepsy: A Review of Cases during 1976 at the Department of Neuropsychiatry of the Yamaguchi University School of Medicine

EEG examination and cranial CT scan were performed almost at the same time on 61 epileptics age 7 to 66 years. In CT scan, abnormal findings in one form or another were found in 32 out of the 61 patients. In three cases, two or more findings such as cerebral atrophy and calcification were shown at the same time. Intracranial tumor was discovered in four cases with late-onset epilepsy. The rate of abnormal findings in CT scan being found was high in partial epileptics, particularly in cases exhibiting elementary seizures. Abnormal CT findings were found very frequently even in the group in which seizures were suppressed by anticonvulsants. Cases showing abnormal CT scan findings were numerous among patients with late-onset epilepsy, thus attesting to the usefulness of CT scan for this group. Coorelation between abnormality in EEG and abnormal findings in CT scan was not too high, but the technique in performing the CT scan and the performance of the scanner should be taken into consideration with this result. It was stressed that examination of epileptics by a combination of EEG and CT scan is very useful.
