title: Behavioural and developmental aspects of primary generalized myoclonic-astatic epilepsy.
abstract: The evolution of psychomotor development and behaviour was studied in 15 children with primary generalized myoclonic-astatic epilepsy and with developmental status adequate for age at final examination at school age following a mean follow-up period of 8.5 years. Temporary arrest of mental and motor development in 4 children was related to high seizure frequency or, in 3, to non-convulsive status. Different types of behavioural abnormalities were documented frequently during the course of the disorder; they were significantly related to active seizure periods and to a lesser extent to anticonvulsant medication. Persistent behavioural abnormalities were noted in 5 children. Hyperkinesia, short attention span and emotional lability were the most frequent complaints. None of the children needed special care and those followed-up until school age were seizure-free, without medication and in classes appropriate for their age. At initial examination the high probability of a favourable prognosis may be anticipated in children with normal development before seizure onset, lack of gross brain pathology and with strong indications (family history and/or EEG criteria) for a genetic predisposition. Nevertheless, repeated systematic re-evaluation for early recognition of possible developmental and/or behavioural deviances throughout the course of illness are recommended.
