A seizure that goes away in a few seconds may be a type of petit mal seizure in epilepsy. Clinical symptoms of a petit mal seizure are usually characterized by a sudden interruption of an ongoing activity, followed by a brief upward rolling of the eyes and a double gaze. If you are talking, the seizure may slow down or stop suddenly, and if you are walking, you may suddenly freeze. If you are eating, you will stop eating in your mouth, and the entire seizure will be brief, disappearing suddenly in a few seconds or tens of seconds. Petit mal seizures belong to a type of epileptic seizure and should be treated with timely medical attention and appropriate antiepileptic drugs such as ethosuximide and lamotrigine under the guidance of a physician, with a good prognosis.
