Abstract

Two children with seizures induced by physical exercise are described. Epilepsy was present from early childhood (age: 4 and 5 months), but the precipitating effect of exercise became evident only later (age: 20 months and 3.5 years). Several treatment regimes were tried, but no satisfactory seizure control could be achieved. In both children no etiological factor was known. MRI, CT and repeated interictal waking and sleeping EEG recordings were normal. Hyperventilation and photostimulation had no effect on the EEG. Physical exercise (e.g., playing football [soccer]) induced clinical seizures and generalized epileptiform EEG abnormalities as recorded by ambulatory cassette EEG (Oxford). Cardiac arrhythmias were excluded by concomitant EEG recording. Extensive metabolic and endocrinologic investigations during and after seizure induction gave normal results. Thus, the pathophysiologic mechanism for exercise-induced seizures remained unclear.
