Acute psychosis during the postictal period in a patient with idiopathic generalized epilepsy: postictal psychosis or aggravation of schizophrenia? A case report and review of the literature

Postictal Psychosis: Case Report and Literature Review

Postictal psychosis (PIP) is one of the most common types of psychosis in epileptic patients. By virtue of the paucity of research on PIP, its pathophysiology remains not completely understood. Our case report describes a clinical picture of PIP, characterized by pleomorphic features, with neither Schneider’s first-rank symptoms nor negative symptoms of schizophrenia, in a longstanding epileptic female patient with a history of nonadherence to antiepileptic treatment and poorly controlled seizures. Additionally, she had previous cognitive impairment and encephalomalacia in the right parietooccipital region as a sequela of a moderate-to-severe traumatic brain injury known to precede the emergence of the epilepsy. In light of our findings, we critically reviewed the current literature on postictal psychoses providing insight into its neurobiological underpinnings.

Persistent catatonia following epileptic seizures: a case report and systematic literature search

BACKGROUND

Catatonia is frequently associated with mood and psychotic disorders as well as with general medical conditions, especially with seizures. In the case of the latter, catatonia mostly resolves when the seizures respond to the anticonvulsive treatment. We report, to our knowledge, the first case of a patient without affective or psychotic disorder, who developed catatonia in the postictum and whose catatonia did not resolve with anticonvulsive treatment, but did so with lorazepam.

CASE PRESENTATION

We describe a 36-year-old man, with no psychiatric history, except for a possible disorder in the use of cannabis, who developed catatonia after epileptic seizures. The catatonia did not respond to the anticonvulsant therapy, but did so to lorazepam 17 mg/d. Lorazepam could be tapered slowly and stopped without reemergence of catatonic signs.

CONCLUSION

Catatonia should be part of the differential diagnosis in patients with bradyphrenia and/or remarkable postictal behavior. This report shows that lorazepam should be taken into consideration (before moving to ECT), in cases of unresolved catatonia, even if the seizures are reduced with anticonvulsants.

Diagnosis and evaluation of hallucinations and other psychotic symptoms in children and adolescents

Recognizing positive psychotic symptoms and their diagnostic context in youth is challenging. A large minority say they "hear things others do not hear," though they seldom present with complaints of hallucinations or delusions. Few have schizophrenia spectrum disorder, but many have other psychiatric disorders. Frequently, they have psychotic symptoms for an extended period before diagnosis. Clinicians should understand psychotic symptoms and their differential diagnoses. This article reviews the epidemiology, associated diagnoses, and prognosis of hallucinations and delusions in youth. Strategies for optimizing the clinical diagnostic interview, appropriate laboratory tests, indications for psychological testing, and rating scales are reviewed.

Psychotic illness in patients with epilepsy

Apart from the rather rare ictal psychotic events, such as non-convulsive status epilepticus, modern epileptic psychoses have been categorized into three main types; chronic and acute interictal psychoses (IIPs) and postictal psychosis (PIP). Together, they comprise 95% of psychoses in patients with epilepsy (PWE). Four major questions, that is, "Is psychosis in PWE a direct consequence of epilepsy or schizophrenia induced by epilepsy?", "Is psychosis in PWE homogeneous or heterogeneous?", "Does psychosis in PWE have symptomatological differences from schizophrenia and related disorders?", "Is psychosis in PWE uniquely associated with temporal lobe epilepsy (TLE)?" are tried to be answered in this review with relevant case presentations. In the final section, we propose a tentative classification of psychotic illness in PWE, with special attention to those who have undergone epilepsy surgery. Psychotic disorders in PWE are often overlooked, mistreated, and consequently lingering on needlessly. While early diagnosis is unanimously supported as a first step to avoid this delay, necessity of switching from antiepileptic drugs with supposedly adverse psychotopic effects. to others is more controversial. To elucidate the riddle of alternative psychosis, we need badly further reliable data.
