Paroxysmal motor disorders during sleep in children are a diagnostic challenge, and careful anamnesis, direct observation of the nocturnal episodes, preferentially with concomitant video-EEG recording, are essential for correct diagnosis and adequate treatment. We present the case of an 11 year-old-boy with frequent, predominantly nocturnal episodes, initially interpreted as genera­lized seizures, with no response to sodium valproate. Video-EEG during sleep showed a seizure characterized by asymmetric tonic posturing of upper limbs followed by left lower limb cycling mo­vements, with right hemispheric epileptiform discharges at onset of the episodes. The patient had had a concussion three years earlier, and brain MRI was normal. Video-EEG findings supported replacement of anticonvulsant drug to oxcarbazepine, which resulted in complete remission of seizures. Seizure semiology and etiology of this particular case of nocturnal frontal lobe epilepsy are discussed.
