What are the consequences of a prolonged epileptic crisis?

The repercussions of a long-lasting epileptic seizure, especially if it is a tonic-clonic seizure ('grand mal'), can include damage to the brain due to lack of oxygen. This can result in various neurological or muscular consequences, and it is important to seek emergency medical attention after experiencing a prolonged seizure. Memory loss can be a potential outcome of a long seizure and may last for hours, days, or even be permanent. If you have recently experienced a seizure, it is crucial to go to the emergency room for evaluation and possible adjustment of medication.
