[Age-related variants of absence in epilepsy in children and adolescents].

Epilepsy consequent to traumas, neuroinfection and perinatal pathology was registered and followed up for 0.5-8 years in 82 patients. At the age of 1.5-15 years they developed absence epileptica. 5 groups of patients were distinguished by type of attack transformation: 1) addition of primary generalized convulsive seizures, 2) addition of secondary generalized convulsive seizures. 3) subsequent addition of absence epileptica to primary generalized convulsive seizures, 4) subsequent addition of absence epileptica to secondary generalized convulsive seizures, 5) transformation of absence epileptica into temporal psychomotor and psychosensory fits. Characteristic for each group EEG readings are delineated.
