Schizophrenia Versus Epileptic Psychosis

According to some studies, there is an increased risk of schizophrenia and schizophrenia-like psychosis in people with a history of epilepsy.1 People seem particularly liable to two types of psychosis: a chronic interictal psychosis that closely resembles schizophrenia; and episodic psychotic states, some of which may arise in close temporal relation with seizure activity.2 The more common by far is the postictal psychosis. [...]the age at onset of psychotic symptoms, its temporal relationship with antiepileptic medication discontinuation, EEG brain changes, the absence of previous psychiatric history, and the fast symptomatic improvement upon correct medication compliance favors the diagnosis of epileptic psychosis.
