title: Electroencephalography and computerized transaxial tomography in epilepsy diagnosis.
abstract: Over a 6-month period 89 patients with epileptic seizures were systematically examined by EEGs and CT. Forty-two percent of all cases showed pathological findings in CT compared to 89% with abnormal EEGs. CT is very useful in identifying organic lesions in the epileptic patient. CT identified 11 cases of supratentorial tumour which were correctly localized by EEG. In patients with seizures after trauma or encephalitis the EEG abnormalities were more than could be detected by CT. The EEG and CT findings in cerebrovascular disorders, alcoholism and other diseases are discussed. A remarkable result is the relatively high percentage of hydrocephalus (23%) in the group of cryptogenic epilepsy. Positive EEG findings as to epilepsy could be seen in 62% of the cases.
