[Complex focal seizures: studies based on the cranial computer tomogram, clinical aspects and longitudinal EEG studies].

Investigations were made on 113 patients suffering from CFS. Definite or highly probable diagnosis often was set up by anamnesis, observation and clinical findings. In 93.8% the EEG was abnormal (seizure patterns 35.8%, focal abnormalities 5 8.4%, focal seizure discharges 14.1%). CCT showed pathological findings only in 58.4%. It was unavoidable in the diagnosis of tumors which were rarely found (8.8%). It showed localised brain lesions of various etiology in 31.8%, seldom perinatal brain damage or unspecific hydrocephali (17.7%). It is concluded that anamnesis, observation, clinical findings and EEG are the primary diagnostic steps in suspected CFS. EEG is the best for the patients survey, CCT, even if mostly indispensable because of its high evidence in morphological brain impairment often is of little or no use in he diagnosis of CFS, EEG and CCT are unavoidable in medical certificates.
