Alternative psychosis (forced normalisation) in epilepsy

Abstract: Forced normalization is a paradoxical relationship between seizure activity and behavioural problems. A 20 year old male with recurrent refractory tonic clonic epilepsy experienced forced normalization, whilst on medication with multiple anti- epileptic drugs (AEDs).(Valproate Sodium, Carbamazepine, and Topiramate). A reduction in the seizure burden correlated with sudden behavioural changes manifesting with aggressive outbursts and violence.. The present case may help clarify the mechanism of forced normaliza… Show more

“…This phenomenon is called forced normalization or alternative psychosis. Forced normalization is a paradoxical relationship between seizure activity and behavioural problems [20]. The concept was introduced in 1953 by Landolt where he described psychotic behaviours with total or partial normalization of EEG [21][22][23].…”

“…The mechanism of forced normalization is still not fully understood, some researchers however had proposed the concept of the kindling phenomenon, the phenomenon of long-term potentiation and the channel disorder theory. Another common theory is that epileptiform discharges may mimic electroconvulsive therapy in a localized area of the brain with the seizure suppression leading to psychosis [20]. Recent studies by Clancy et al have estimated that the prevalence of psychosis in a population based studies at between 2-7% while the estimated prevalence of psychosis is 10-19% in patients with Temporal Lobe Epilepsy or refractory epilepsy [24].…”

“…Hauptrisikofaktor für das Auftreten einer AP oder FN ist die Anfallsunterdrückung durch Antiepileptika [2,5,19]. Bei fast allen Antiepileptika wurde das Auftreten einer AP beobachtet, allerdings in sehr unterschiedlicher Häufigkeit [2,3,9,17,18,20,21]. Vor Einführung der neuen Antiepileptika war das Risiko einer AP bzw.…”
