Multiple hypotheses exist about the pathophysiology of Postictal Psychosis (PIP). As the clinical manifestations of PIP are roughly stereotyped, we assumed the existence of a common neurological pathway. This study aimed to determine if a specific brain network sustained the psychotic episode, regardless of the localization of the epileptogenic zone. We conducted a systematic review following the PRISMA guidelines. We included a total of 24 studies providing electrophysiological results(n=22) and metabolic imaging performed during the PIP(n=5).
