hi, this could be due to febrile seizure. In Febrile seizure, there is seizure followed by history of high grade fever. it is usually not associated with intracranial infection or other identifiable cause. It usually occurs within 24 hours of a fever. if diagnosis of Febrile seizure is confirmed, then you should give an antipyretic drug like Paracetamol as soon as fever occurs so that incidence of February seizure can be prevented. If episode of season occur then child should be immediately taken to hospital for examination. And imaging like CT scan or MRI brain should be done. Take care.
