Clinical and sociodemographic characteristics of patients with epilepsy attended at a regional reference psychiatric emergency unit.

Objective: Epilepsy is one of the most prevalent chronic neurological diseases, presenting a high frequency of psychiatric disorders (PD). This study sought to evaluate the clinical and sociodemographic profile of patients with epilepsy (PWE) attended at a regional reference psychiatric emergency unit.

Methods: A retrospective, cross-sectional, and descriptive observational study was conducted utilizing a patient record database of individuals with epilepsy who were attended in a regional reference psychiatric emergency unit between January 2018 and August 2022.

Generalized Joint Hypermobility: A Statistical Analysis Identifies Non-Axial Involvement in Most Cases.

Context: Joint hypermobility (JH) represents the extreme of the normal range of motion or a condition for a group of genetically determined connective tissue disorders. Generalized joint hypermobility (GJH) is suspected when present in all four limbs and the axial skeleton, scored in prepubescent children and adolescents by a Beighton Score (BS) ≥ 6. Parameters are also used to identify GJH in hypermobile Ehlers-Danlos syndrome (hEDS) and hypermobility spectrum disorders (HSDs).

Clinical and epidemiological profile of patients with mental disorders in a specialized outpatient clinic and its role in the psychosocial care network.

Introduction: Mental health disorders (MHDs) are responsible for much impairment of quality of life in Brazil and worldwide. Early diagnosis and effective treatment strategies are required due to the heterogeneous symptoms and multifactorial etiology.

Methods: A descriptive retrospective observational study was performed aiming to characterize the clinical and psychiatric profiles of patients with MHD attending a Brazilian public tertiary psychiatric outpatient clinic, which is a reference health service for more than 2 million inhabitants.

Conceptions about the Use of Cannabis among Medical Students from Public Universities.

Background: Substance abuse is a public health concern given its high prevalence worldwide. The early onset of such abuse predicts greater severity of addiction, morbidity, and use of multiple drugs. The use of psychoactive substances among Brazilian university students is frequent and cannabis stands out as the most consumed illicit drug.

Oxidative stress biomarkers in treatment-responsive and treatment-resistant schizophrenia patients.

Introduction: Schizophrenia is a complex psychiatric disorder that affects approximately twenty million people worldwide. Various factors have been associated with the physiopathology of this disease such as oxidative stress, which is an imbalance between pro-oxidant and antioxidant molecules.

Objective: This study evaluated the association between biomarkers of oxidative stress and response to pharmacological treatment among patients with schizophrenia in the context of their clinical information, demographic data, and lifestyle.

Do Hippocampal Neurons Really Count for Comorbid Depression in Patients With Mesial Temporal Lobe Epilepsy and Hippocampal Sclerosis? A Histopathological Study.

Depression is the most frequent psychiatric comorbidity seen in mesial temporal lobe epilepsy (MTLE) patients with hippocampal sclerosis (HS). Moreover, the HS is the most frequent pathological hallmark in MTLE-HS. Although there is a well-documented hippocampal volumetric reduction in imaging studies of patients with major depressive disorder, in epilepsy with comorbid depression, the true role of the hippocampus is not entirely understood.

Can We Anticipate and Prevent the Occurrence of Iatrogenic Psychiatric Events Caused by Anti-seizure Medications and Epilepsy Surgery?

Psychiatric disorders and behavioral manifestations in patients with epilepsy have complex and multifactorial etiologies. The psychotropic properties of anti-seizure medications (ASMs) and psychiatric effects of epilepsy surgery can result in iatrogenic psychiatric symptoms or episodes or can yield a therapeutic effect of underlying psychiatric disorders and have a significant impact on the patients' quality of life. The aims of this chapter are to review the available evidence of psychotropic properties of ASMs, which may be responsible for iatrogenic psychiatric symptoms and/or disorders.

Neuropsychological findings related to the presence of pre-surgical comorbid depression in Latin-American patients with mesial temporal lobe epilepsy and hippocampal sclerosis.

Purpose: To evaluate the neuropsychological findings related to the presence of pre-surgical comorbid depression in Latin-American patients with mesial temporal lobe epilepsy (MTLE) and unilateral hippocampal sclerosis (HS).

Method: Patients with drug-resistant MTLE and unilateral, left (L-) or right (R-) HS were studied. To diagnose depression, psychiatrists with expertise in epilepsy applied a semi-structured interview based on DSM.

Electroencephalogram alterations associated with psychiatric disorders in temporal lobe epilepsy with mesial sclerosis: A systematic review.

Temporal lobe epilepsy (TLE) is the most frequent focal epilepsy in adults and has been associated with psychiatric disorders (PD), especially the TLE with mesial temporal sclerosis (MTS). Electroencephalogram (EEG) could help in locating the epileptogenic zone and supply information regarding cerebral electric activity in these patients. However, there is a scarcity of knowledge about the association between EEG findings and comorbid PD in TLE.

Effects of a brief psychotherapeutic intervention on resilience and behavior in patients with drug-resistant mesial temporal lobe epilepsy and late seizure recurrence after surgery.

Seizure recurrence (SR) after epilepsy surgery in patients with medically resistant temporal lobe epilepsy and mesial temporal sclerosis (TLE-MTS) can compromise medical treatment and quality of life (QOL). However, there is a scarcity of interventions specifically addressing this issue in the literature. We aimed to evaluate the impact of a four-week psychotherapeutic intervention on the levels of resilience, behavioral symptoms, and QOL of patients with drug-resistant TLE-MTS who underwent corticoamygdalohippocampectomy (CAH) and who presented with late SR.

Revisiting personality in epilepsy: Differentiation of personality in two epilepsies starting in adolescence.

Purpose: The purpose of this study was to investigate personality characteristics and clinical parameters in two well-defined epilepsies: mesial temporal lobe epilepsy related to hippocampal sclerosis (MTLE/HS) and juvenile myoclonic epilepsy (JME) through NEO Revised Personality Inventory (NEO-PI-R) and Neurobehavior Inventory (NBI) standardized instruments.

Methods: One hundred patients undergoing corticoamygdalohippocampectomy (CAH), 100 patients with JME, and 100 control subjects answered the personality measures. Clinical parameters such as psychiatric symptoms, seizure frequency, duration of epilepsy, and side of the lesion in MTLE/HS group were investigated.

Are psychogenic nonepileptic seizures risk factors for a worse outcome in patients with refractory mesial temporal epilepsy submitted to surgery? Results of a retrospective cohort study.

Objective: The objective of this study was to verify if the presence of psychogenic nonepileptic seizures (PNES) could be a risk factor precluding corticoamygdalohippocampectomy (CAH) in patients with refractory temporal lobe epilepsy (TLE) and mesial temporal sclerosis (MTS) (TLE-MTS).

Methods: This retrospective cohort study analyzed medical data of patients with refractory TLE-MTS accompanied in a Brazilian epilepsy surgery center. Presurgical psychiatric evaluations were performed using the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria.

Prognosis of Juvenile myoclonic epilepsy with eye-closure sensitivity.

Purpose: Eye closure sensitivity (ECS) has been described as a reflex trait in juvenile myoclonic epilepsy (JME). However, there is no consensus regarding its significance on prognosis. The aim of this study is to clarify the long-term impact of ECS documented by a clinical interview and a video-EEG neuropsychological protocol (VNPP) in a series of 133 JME patients.

Effects of a psychotherapeutic group intervention in patients with refractory mesial temporal lobe epilepsy and comorbid psychogenic nonepileptic seizures: A nonrandomized controlled study.

Purpose: Psychogenic nonepileptic seizures (PNES) are paroxysmal episodes superficially resembling epileptic seizures but are not associated with any electrical abnormalities. Despite the existence of recent evidence addressing psychological interventions on PNES, there is a scarcity of studies investigating such interventions on patients with dual diagnoses, such as in temporal lobe epilepsy/mesial temporal sclerosis (TLE-MTS) with comorbid PNES; TLE-MTS is a very frequent epilepsy syndrome found in tertiary centers. We aimed to investigate the effects of a group psychotherapeutic intervention program based on cognitive-behavioral therapy (CBT) on patients dually diagnosed with TLE-MTS and PNES treated in a tertiary center.

Oxidative stress in patients with refractory temporal lobe epilepsy and mesial temporal sclerosis: Possible association with major depressive disorder?

Objective: The objective was to evaluate the genetic and biochemical profiles associated with oxidative stress (OS) in patients with temporal lobe epilepsy with mesial temporal sclerosis (TLE-MTS) and a healthy control group, and also to verify the possible existence of association between OS markers and psychiatric disorders (PD) in group with TLE-MTS.

Methods: Forty-six patients with refractory TLE-MTS and 112 healthy controls were included. Psychiatric evaluation occurred through Diagnostical and Statistical Manual of Mental Disorders (DSM-5) criteria.

Attention and memory deficits in crack-cocaine users persist over four weeks of abstinence.

Background: Crack-cocaine addiction is an important public health problem worldwide. Although there is not a consensus, preliminary evidence has suggested that cognitive impairments in patients with crack-cocaine dependence persist during abstinence, affecting different neuropsychological domains. However, few studies have prospectively evaluated those deficits in different phases of abstinence.

Clinical and sociodemographic variables associated with interictal dysphoric disorder and interictal personality in patients with drug-resistant temporal lobe epilepsy: A controlled study.

Psychiatric disorders (PD) have an elevated prevalence and an important negative impact on patients with epilepsy (PWE) since they are associated with lower quality of life and clinical refractoriness. However, it is also necessary to identify behavioral conditions possibly associated with epilepsy that are not part of the standard psychiatric classifications, such as Interictal Dysphoric Disorder (IDD) and Interictal Personality (IP). The frequency of IDD and IP in patients with drug-resistant temporal lobe epilepsy and mesial temporal sclerosis (TLE-MTS) was assessed.

The approach to patients with psychogenic nonepileptic seizures in epilepsy surgery centers regarding diagnosis, treatment, and education.

Previous studies, using surveys, provided an understanding about how health-care providers address patients with PNES. To date, there is limited information on the management of patients with PNES by tertiary referral centers for epilepsy. In this study, we surveyed 11 Brazilian epilepsy center directors about diagnosis, treatment, education and research on PNES.

Factors predicting the outcome following surgical treatment of mesial temporal epilepsy due to mesial temporal sclerosis.

Background: Mesial temporal sclerosis (MTS) is the most common disease found in an epilepsy surgery series. Early age of onset, a history of febrile convulsions, epileptiform discharges on EEG, duration of epilepsy, number of generalized seizures and severity of psychiatric disorders are possible prognostic factors in patients with MTS.

Objective: The aim of this study is to review the clinical, semiotic, psychological, electrophysiological and neuroradiological researches and relate their findings to the prognosis of patients with MTS who underwent anteromedial temporal lobectomy (ATL).

Microsurgical treatment of patients with refractory epilepsy and mesial temporal cavernous malformations: Clinical experience of a tertiary epilepsy center.
