What is Postictal psychosis?
Postictal psychosis has been estimated to affect between 6% and 10% of people with epilepsy. It involves psychiatric symptoms that occur within 7 days (usually within 1 to 3 days) after a seizure or seizure cluster in a person who does not have these symptoms at other times (or at least has them in a much milder form).
