Epilepsy Behav 2023; 140:109087. [PMID: 36702055 DOI: 10.1016/j.yebeh.2023.109087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Revised: 01/02/2023] [Accepted: 01/03/2023] [Indexed: 01/26/2023]
Abstract
OBJECTIVES To clarify the pathophysiology of psychoses after the new administration of antiepileptic drugs (AED), we analyzed the annual incidence, timing of development, and duration of episodes. METHODS Psychotic outcomes in the first 6-month period after an AED or non-AED administration in patients with focal epilepsy were exhaustively reviewed in eight Japanese neuropsychiatry institutions. In cases with psychotic episodes, the subtype of psychosis, timing of development, previous history of psychosis, and duration of the episode were evaluated. RESULTS Between 1981 and 2015, 5018 new drugs (4402 AED and 616 non-AED) were administered to 2067 patients with focal epilepsy. In the first 6-month period, 105 psychotic episodes occurred (81 interictal psychosis [IIP] and 24 postictal psychosis). Furthermore, 55 cases were first episodes and 50 were recurrent episodes. The frequency of psychoses is significantly higher after AED administration (n = 102) compared with non-AED administration (n = 3). Psychosis occurred most frequently in the initial 1-month period after new-AED administration and tended to decrease with increasing time. The estimated annual incidence of all psychoses after a new AED administration was 3.5% (2.0% for first-episode psychosis and 1.8% for first-episode IIP). Duration of psychoses (mean, 38.5 weeks) was equivalent to overall IIP. Duration of IIP did not shorten with discontinuation of newly administered AED. SIGNIFICANCE Patients with epilepsy exhibit psychosis more frequently after new AED administration than after non-AED administration. This study shows the pathophysiology of psychoses after AED administration with annual incidence, the timing of development, and the duration of PAP, which have rarely been reported.

Abstract
Psychotic disorders can have a primary or secondary origin. Primary psychosis includes pathologies such as paranoid schizophrenia, acute psychotic episodes, schizoaffective disorder, and other chronic psychiatric disorders. However, in secondary psychosis, there is an organic cause that explains the appearance of psychotic symptoms, such as those secondary to the consumption of psychoactive substances or some neurological or systemic diseases. Psychosis in epilepsy falls under secondary psychosis. It may present as hallucinations and delirium reminiscent of some primary psychoses such as schizophrenia. We present the case of a 57-year-old female suffering from temporal lobe epilepsy who developed psychotic symptoms and whose definitive diagnosis was a challenge given the similarities between some alternative diagnoses, mainly between interictal psychosis of epilepsy and late-onset schizophrenia. We also review the relevant literature. We consider that more studies are required to clarify the relationship between epilepsy and psychosis.

Quantitative psychopathology of interictal psychosis in epilepsy; interaction between epilepsy-related and psychosis-general effects. Epilepsy Behav 2021; 123:108214.

Abstract
OBJECTIVE There is a historical debate whether psychopathology of epilepsy psychosis is unique to epilepsy or common to other psychoses. However, a large comprehensive studies on this issue are scarce. To clarify the characteristics of interictal psychosis (IIP), we evaluated psychopathology quantitatively. METHODS This study included 150 patients with IIP (epilepsy+/psychosis+), 187 patients with schizophrenia (SC: epilepsy-/psychosis+), 182 patients with epilepsy (EP: epilepsy+/psychosis-), and 172 non-clinical individuals (NC: epilepsy-/psychosis-). The IIP group comprised 127 chronic and 23 brief psychoses. Age, sex, and years of education, onset and duration of psychosis, and onset and duration of epilepsy were matched among the groups. The psychopathology was evaluated using the 16-item Brief Psychiatric Rating Scale (BPRS), which comprises three symptom factors namely negative symptoms (NS), positive symptoms (PS), and anxiety-depressive symptoms (ADS). RESULTS For overall 16-BPRS and NS factor scores, there were significant interactions between epilepsy-related (epilepsy+/-) and psychosis-general (psychosis+/-) effects. The EP exhibited higher scores than did the NC, whereas the IIP exhibited lower scores than did the SC. For PS and ADS factor scores, the IIP and SC exhibited a significant psychosis-general effect. Chronic IIP was associated with more serious psychopathologies than was brief IIP. However, limited with chronic IIP, there was a significant interaction between epilepsy-related and psychosis-general effects on the overall 16-BPRS and NS factor scores. CONCLUSION These findings demonstrate the first large quantitative evidence on the unique psychopathology of IIP which has been only narratively described. The psychopathology is associated with the interaction between epilepsy-related and psychosis-general effects.

Abstract
Objectives: Psychiatric symptoms and disorders are commonly reported with epilepsy. This study aimed to determine the prevalence of interictal psychosis (IIP) in adults with epilepsy and its risk predictors. Methods: The study included 710 patients (mean age: 36.40 years; age at onset: 13.58 years; duration of epilepsy: 22.80 years). All underwent neurological and psychiatric interviewing, electroencephalography and brain imaging. Results: IIP was reported in 20.65%, of them 50% had temporal lobe epilepsy with impaired awareness and/or to bilateral tonic clonic, 42.47% had frontal lobe epilepsy with impaired awareness and/or to bilateral tonic clonic and 7.53% had generalized tonic-clonic seizures. Compared to patients without psychosis, patients with psychosis were older at age of examination, had earlier age at onset, frequent seizures, longer duration of epilepsy and long-term antiepileptic drugs therapy and many relatives with epilepsy. Nearly 76.71% had history of postictal psychosis (PIP). The mean age of onset of IIP was 30.45 years and its mean duration was 3.84 months. Approximately 22% of patients with IIP had family history of psychosis. Patients developed IIP 10 years or more after epilepsy onset. Multivariate logistic regression analyses showed that predictors for IIP were the age at onset and duration of epilepsy, number of seizures, family history of epilepsy or psychosis, history of PIP and different types of epilepsy. Conclusion: IIP is not infrequent with chronic epilepsy regardless to its type. These findings emphasize the importance of optimizing patients' treatment and early recognition and management of IIP. Abbreviations: IIP: interictal psychosis; PIP: post-ictal psychosis; TLE: temporal lobe epilepsy; FLE: frontal lobe epilepsy; GTC: generalized tonic clonic; AEDs: antiepileptic drugs; CBZ: carbamazepine; VPA: valproate; LEV: levetiracetam; APDs: antipsychotic drugs.

Epilepsy Behav 2018; 88:54-60. [PMID: 30241054 DOI: 10.1016/j.yebeh.2018.09.001] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2018] [Revised: 08/28/2018] [Accepted: 09/01/2018] [Indexed: 11/28/2022]
Abstract
The recognition and treatment of psychosis in persons with epilepsy (PWE) is recommended with the apparent dilemma between treating psychosis and opening the possibility of exacerbating seizures. The pooled prevalence estimate of psychosis in PWE is 5.6%. It has been proposed that a 'two hit' model, requiring both aberrant limbic activity and impaired frontal control, may account for the wide range of clinical phenotypes. The role of antiepileptic drugs in psychosis in PWE remains unclear. Alternating psychosis, the clinical phenomenon of a reciprocal relationship between psychosis and seizures, is unlikely to be an exclusively antiepileptic drug-specific phenomenon but rather, linked to the neurobiological mechanisms underlying seizure control. Reevaluation of antiepileptic treatment, including the agent/s being used and degree of epileptic seizure control is recommended. The authors found very few controlled studies to inform evidence-based treatment of psychosis in PWE. However, antipsychotics and benzodiazepines are recommended as the symptomatic clinical treatments of choice for postictal and brief interictal psychoses. The general principle of early symptomatic treatment of psychotic symptoms applies in epilepsy-related psychoses, as for primary psychotic disorders. In the authors' experience, low doses of antipsychotic medications do not significantly increase clinical risk of seizures in PWE being concurrently treated with an efficacious antiepileptic regimen.

Abstract
We retrospectively analyzed data of patients with epilepsy (n=1434) evaluated with prolonged EEG monitoring in order to estimate the prevalence of postictal psychosis (PP) and interictal psychosis (IP), to investigate a potential association of psychosis subtype with epilepsy type, and to assess differences between PP and IP. The overall prevalence of psychosis was 5.9% (N=85); prevalence of PP (N=53) and IP (N=32) was 3.7% and 2.2%, respectively. Of patients with psychosis, 97.6% had localization-related epilepsy (LRE). Prevalence of psychosis was highest (9.3%) in patients with temporal lobe epilepsy (TLE). When comparing PP with IP groups on demographic, clinical, and psychopathological variables, patients with IP were younger at occurrence of first psychosis (P=0.048), had a shorter interval between epilepsy onset and first psychosis (P=0.002), and more frequently exhibited schizophreniform traits (conceptual disorganization: P=0.008; negative symptoms: P=0.017) than those with PP. Postictal psychosis was significantly associated with a temporal seizure onset on ictal EEG (P=0.000) and a higher incidence of violent behavior during psychosis (P=0.047). To conclude, our results support the presumption of a preponderance of LRE in patients with psychosis and that of a specific association of TLE with psychosis, in particular with PP. Given the significant differences between groups, PP and IP may represent distinct clinical entities potentially with a different neurobiological background.

Abstract
Psychosis of epilepsy (POE) is a term applied to a group of psychotic disorders with a distinct phenomenology in which potential etiopathogenic mechanisms are believed to be closely related to a seizure disorder. POE can present as interictal psychotic episodes, which may often differ semiologically from primary schizophrenic disorder. They may present as ictal or postictal psychotic episodes and may be the expression of an iatrogenic process to pharmacologic and/or surgical interventions.Epilepsy and POE have a complex and bidirectional relation, as not only are patients with epilepsy at greater risk of developing a psychotic disorder, but patients with a primary psychotic disorder are also at greater risk of developing epilepsy. The prevalence of POE is more than 7 times higher than the frequency of primary schizophreniform disorders in the general population. While POE has been associated with focal epilepsy of temporal and frontal lobe origin, its etiology and pathophysiology of POE have yet to be established.The treatment of all forms of POE, with the exception of ictal psychotic episodes, requires the use of antipsychotic drugs, preferably the atypical antipsychotic agents with a very low or negligible potential to lower the seizure threshold (eg, risperidone, apiprazole), starting at a low dose with stepwise increments.

Abstract
Psychiatric disorders represent a frequent comorbidity in patients with epilepsy affecting quality of life, morbidity and mortality. Evidence-based data on the management of these conditions are limited but a number of recommendations are now available to guide clinical practice. The present paper reviews the pharmacological treatment of psychiatric problems in epilepsy with special attention to data coming from randomised controlled trials (RCTs), pharmacological interactions with AEDs and the issue of seizure worsening during treatment with psychotropic drugs. Epidemiologically or clinically relevant psychiatric conditions are discussed namely mood and anxiety disorders, psychoses and attention deficit hyperactivity disorder.

Abstract
Epilepsy is one of the most common neurologic illnesses. This condition afflicts 2.9 million adults and children in the US, leading to an economic impact amounting to $15.5 billion. Despite the significant burden epilepsy places on the population, it is not very well understood. As this understanding continues to evolve, it is important for clinicians to stay up to date with the latest advances to provide the best care for patients. In the last 20 years, the US Food and Drug Administration has approved 15 new antiepileptic drugs (AEDs), with many more currently in development. Other advances have been achieved in terms of diagnostic modalities like electroencephalography technology, treatment devices like vagal nerve and deep-brain stimulators, novel alternate routes of drug administration, and improvement in surgical techniques. Specific patient populations, such as the pregnant, elderly, those with HIV/AIDS, and those with psychiatric illness, present their own unique challenges, with AED side effects, drug interactions, and medical-psychiatric comorbidities adding to the conundrum. The purpose of this article is to review the latest literature guiding the management of acute epileptic seizures, focusing on the current challenges across different practice settings, and it discusses studies in various patient populations, including the pregnant, geriatric, those with HIV/AIDS, comatose, psychiatric, and "pseudoseizure" patients, and offers possible evidence-based solutions or the expert opinion of the authors. Also included is information on newer AEDs, routes of administration, and significant AED-related drug-interaction tables. This review has tried to address only some of these issues that any practitioner who deals with the acute management of seizures may encounter. The document also highlights the numerous avenues for new research that would help practitioners optimize epilepsy management.

Abstract
Psychosis temporally related to seizure episodes has been a recognized entity with much clinical attention, yet there are less clear guidelines for treatment. Presence of perceptual disturbances and cognitive impairment symptoms make the differentiation between primary psychoses and seizure- related psychoses blurred. Moreover, there are only a few reported cases describing clinical presentation, diagnostic dilemma and treatment challenges when these two entities are present at the same time, with overlapping symptomatology. We describe such a case where the presence of these two problems complicated the diagnoses and the patient's subsequent management required a very intricate collaboration between psychiatry and neurology. In addition, we review available published articles including case reports, studies, and review articles regarding the diagnosis and treatment of this complicated clinical presentation. Some of the analyses were reviewed in detail and resulting outcomes are discussed. Finally, we review the diagnostic and treatment guidelines in the context of the presenting case.

Abstract
To investigate whether addition of antipsychotic drugs (APD) would increase seizure frequency in epilepsy patients who were already treated with anti-epileptic drugs (AED), we compared a one-year seizure control outcome in 150 epilepsy patients with APD treatment for psychiatric conditions and 309 epilepsy patients without APD treatment matched for ages at epilepsy onset and the baseline evaluation and types of epilepsy. The seizure frequency was recorded at the baseline (immediately before the start of APD) and after the 1st, 3rd, 6th and 12th months. The seizure outcome at each of the four follow-up points was compared with the baseline. The seizure outcome was compared between the two groups as a whole and according to the types of epilepsy (idiopathic generalized and partial epilepsies). In the APD group, the seizure outcome was also analyzed according to the types of APD (first and second generation APD and combination of first and second generation APD) and the types of psychiatric conditions (psychosis and non-psychosis). The seizure outcome was significantly better in the APD group than control group at all the four follow-up points. According to the epilepsy types, the improvement in the seizure outcome was only observed in the patients with partial epilepsy. Of the APD group, there was no significant difference in the seizure outcome according to the types of APD or the psychiatric conditions. In epilepsy patients who are already treated with AED, APD treatment seems safe in seizure control outcome for treatment of psychiatric conditions.

Abstract
Childhood-onset epilepsy is associated with psychiatric and cognitive difficulties and with poor social outcomes in adulthood. Some antiepileptic drugs adversely affect behavior in susceptible children with easy-to-control or refractory epilepsies, contributing to a high risk of psychological and psychiatric disturbance. Studies had demonstrated that patients with benign rolandic epilepsy and absence epilepsy had more aggressive behavior, depression, and anxiety disorders than control children. Psychiatric comorbidities are strongly associated with a poor long-term health-related quality of life in childhood-onset epilepsy, which suggests that comprehensive epilepsy care must include screening and long-term treatment for these conditions, even if seizures remit.

Abstract
Treatment protocols for interictal psychosis (IIP) of patients with epilepsy have not yet been established. We aimed to clarify the effects of antipsychotic drugs (APDs) on duration of IIP episodes. We studied 393 IIP episodes in 200 patients with epilepsy in accordance with our empirical treatment protocol. The duration of all the episodes and APD treatments were reviewed. Antipsychotic drugs were used in 338 episodes and not used in 55 episodes (non-APD group). The APDs used in the treatment of IIP episodes were divided into the following three groups: first-generation APDs (FAPD, n=252), second-generation APDs (SAPD, n=44), and the combination of first- and second-generation APDs (CAPD, n=42). The non-APD group showed a significantly shorter episode duration than did the APD group (F=6.05, p=0.014). Among the 3 APD groups (FAPD, SAPD, and CAPD), there was a significant difference in duration of IIP episode (F=8.65, p=0.000). Whereas the duration of episodes was significantly longer in the CAPD group than in the other two groups, it was not significantly different between the FAPD and SAPD groups. Our findings further to clarify the nature of IIP and add further perspectives on treatment protocols for IIP.

Abstract
In patients with epilepsy, coexisting psychoses, either interictal (IIP) or postictal (PIP), are associated with serious disturbance in psychosocial function and well-being, and often require the care of a specialist. Unfortunately, evidence-based treatment systems for psychosis in patients with epilepsy have not yet been established. This article aims to propose concise and practical treatment procedures for IIP and PIP based on currently available data and international consensus statements, and primarily targeting nonpsychiatrist epileptologists who are often the first to be involved in the management of these complex patients. Accurate and early diagnosis of IIP and PIP and their staging in terms of acuity and severity form the essential first step in management. It is important to suspect the presence of psychosis whenever patients manifest unusual behavior. Knowledge of psychopathology and both individual and epilepsy-related vulnerabilities relevant to IIP and PIP facilitate early diagnosis. Treatment for IIP involves (1) obtaining consent to psychiatric treatment from the patient, whenever possible, (2) optimization of antiepileptic drugs, and (3) initiation of antipsychotic pharmacotherapy in line with symptom severity and severity of behavioral and functional disturbance. Basic psychosocial interventions will help reinforce adherence to treatment and should be made available. Due consideration must be given to patients' ability to provide informed consent to treatment in the short term, with the issue being revisited regularly over time. Given the often prolonged and recurrent nature of IIP, treatment frequently needs to be long-term. Treatment of PIP consists of two aspects, that is, acute protective measures and preventive procedures in repetitive episodes. Protective measures prioritize the management of risk in the early stages, and may involve sedation with or without the use of antipsychotic drugs, and the judicious application of local mental health legislation if appropriate. As for preventative procedures, optimizing seizure control by adjusting antiepileptic drugs or by surgical treatment is necessary.
