Summary:Purpose: To determine if, and how, epileptiform EEG discharges in children were influenced by physical exercise. Methods: Twenty‐six children with intractable partial and generalized epilepsy exercised during video‐telemetry recording, aiming at exhaustion after ∼10 min. Results: During the exercise, epileptiform discharges decreased in 20 of 26 children (17 children had at least 25% reduction) and showed a rebound increase after the exercise (17 of 26 children) compared to baseline conditions. This exercise‐induced reduction in epileptiform discharges reached statistical significance only in the 16 patients with localization‐related epilepsy. Five patients showed an atypical EEG response to exercise with either unchanged or increased epileptiform activity while exercising. As compared to the other patients, these 5 children had experienced frequent clinical seizures during or immediately after exercise in their leisure time. Conclusions: In the majority of the tested children, epileptiform EEG discharges decreased during exercise. “Exercise‐EEG” may be a helpful diagnostic tool to identify patients who are disposed to have exercise‐induced seizures.
