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. Statistical analysis consisted of the mean and standard deviation (SD) of each variable. Student's t-test or Fisher exact test were used according to the variable studied. RESULTS: The three groups were within the average range of NEO-PI-R and NBI, although 'tendencies' and differences were demonstrated. The MTLE/HS and control subjects had a similar profile: low scores in Neuroticism and high in Conscientiousness (r = -0.330; p < 0.001/r = -0.567; p < 0.001, respectively) in opposition to what occurred in JME, low in Conscientiousness and high in Neuroticism (r = -0.509; p = 0.005). The NBI 'sense of personal destiny' trait was higher (3.15; p = 0.003) in MTLE/HS than in JME and controls. The JME 'law and order' scores were lower than in other groups (p = 0.024). A tendency towards specific NBI traits differentiates MTLE/HS (Factor 3) from JME (Factor 1) groups. Psychiatric symptoms and seizure frequency were correlated with worse scores in NBI and, especially, in Neuroticism domain of NEO-PI-R. CONCLUSION: Specific personality features were linked to each epileptic disease. These findings highlight the importance of considering unique features linked to epilepsy conditions in daily clinical observation to develop support programmes.

Epilepsy for primary health care: a cost-effective Latin American E-learning initiative.

A lack of neurologists in Latin America forces primary health care providers to manage epilepsy. With the main goal of improving diagnostic and therapeutic management of patients with epilepsy through training of physicians in the primary health care level, the International League Against Epilepsy Education Commission (2013-2017) created a low-cost, regional, virtual course. The course, set-up in Moodle platform, was structured in eight modules, each lasting for a week. Teaching was based on written didactic material, videos, and interactive discussions, both in Spanish and Portuguese. Topics included epidemiology, diagnosis, classification, treatment, prognosis, social issues, and epilepsy policies. Each course was limited to 50 participants and priority was given to general practitioners. Certification was given to those approving the final examination. Since 2015, five courses have been developed, involving 143 participants from 17 countries and 21 tutors. Of the participants, 61% worked in primary health care services. A total of 129 participants (90%) completed the course, and 110 submitted the final examination with an approval rate of 95%. From 85 participants completing the course evaluation, 98% would recommend the course to other colleagues, and 99% showed interest in taking other similar courses. High self-confidence for the management of patients with epilepsy increased from 21% at baseline to 73% after the course. The online course on epilepsy for primary care physicians in Latin America was shown to be a cost-effective course, with good retention and excellent approval rates. Our current challenges include periodic updating, complete self-sustainability, and exploring different strategies to reach our target audience more effectively.

Association between leisure time, physical activity, and mood disorder levels in individuals with epilepsy.

The aim of this study was to investigate the association between physical activity levels (occupational, sports, and leisure time activities), depression, anxiety, and epilepsy. The behavioral outcomes of individuals with epilepsy (E) were also compared with healthy control subjects (C). The sample included 31 individuals with epilepsy (12 with idiopathic generalized epilepsy and 19 with partial epilepsy) and 31 control subjects. Self-rating questionnaires were used to assess mood (State-Trait Anxiety Inventory and Beck Depression Inventory), anxiety, and depression as well as habitual physical activity. Patients with epilepsy were more severely impaired compared to control subjects in both mood questionnaires and presented higher levels of depression (35%), state anxiety (18%), and trait anxiety (12.6%) when compared to the C group. Although physical activity level did not differ significantly between groups, linear regression analyses showed that the physical activity leisure level predicted 31% of depression levels and 26% of anxiety levels in the E group. These data suggest that low levels of physical activity may be considered a risk factor for the development of depression and anxiety and can play an important role in the quality of life of individuals with epilepsy.

Serum levels of magnesium in sudden cardiac deaths among people with schizophrenia: hit or miss?

Schizophrenia is a devastating mental disorder, affecting cognitive, emotional, and behavioral conditions, ability to work, social functioning, family stability and self-esteem of the patient. People with schizophrenia show a two to three-fold increased risk to die prematurely than those without schizophrenia. Understanding the mechanisms behind sudden cardiac death in individuals with schizophrenia is a key to prevention. Although different mechanisms may be related, there are clear indications that cardiac abnormalities play a potential role. Some antipsychotics may be associated with cardiovascular adverse events, e.g., QT interval prolongation, metabolic dysfunction, blood pressure and heart rate alterations. Magnesium (Mg) abnormalities may lead to various morphological and functional dysfunctions of the heart and low levels of serum Mg are considered to be at high risk for sudden cardiac death. As low serum Mg is associated with detrimental effects on the heart and that antipsychotic-treated schizophrenia patients frequently affect the heart rate, possibly, these factors together must change the normal functioning of the heart and consequently being able to culminate in a catastrophic event.

Serum levels of magnesium in sudden cardiac deaths among people with schizophrenia: hit or miss? / Níveis séricos de magnésio em morte súbita entre pessoas com esquizofrenia: erro ou acerto?

A esquizofrenia é uma doença mental que afeta as condições cognitivas, emocionais e comportamentais, a capacidade de trabalho, a estabilidade familiar e social e a auto-estima do paciente. Pessoas com esquizofrenia apresentam um risco de duas a três vezes maior de morrer prematuramente em relação às pessoas sem esquizofrenia. A compreensão dos mecanismos envolvidos na morte súbita em indivíduos com esquizofrenia é de suma importância para sua prevenção. Apesar de diferentes mecanismos associados à doença, evidências mostram que as anormalidades cardíacas desempenham papel importante neste contexto. Alguns antipsicóticos podem estar associados com eventos cardiovasculares adversos, como o prolongamento do intervalo QT, disfunção metabólica e alterações na pressão arterial e no ritmo cardíaco. Anormalidades do magnésio (Mg) podem levar a várias alterações morfológicas e funcionais do coração assim como a um alto risco para a morte súbita. Como baixos níveis séricos de Mg estão associados a efeitos nocivos ao coração e indivíduos com esquizofrenia tratados com antipsicóticos frequentemente apresentam alteração do ritmo cardíaco, possivelmente, estes fatores em conjunto podem alterar o funcionamento normal do coração e, consequentemente, culminar em um evento catastrófico.

Sudden unexpected death in epilepsy: an important concern.

Epilepsy is one of the most common neurologic problems worldwide. Unfortunately, individuals with epilepsy are at higher risk of death than the general population, and sudden unexpected death in epilepsy is the most important direct epilepsy-related cause of death. In this review article, our research group focused on the risk factors, mechanisms and preventative measures obtained from clinical and experimental studies on sudden unexpected death in epilepsy.

Thyroid gland and cerebella lesions: New risk factors for sudden cardiac death in schizophrenia?

People with schizophrenia show a two to threefold increased risk to die prematurely than those without schizophrenia. Patients' life style, suicide, premature development of cardiovascular disease, high prevalence of metabolic syndrome and sudden cardiac death are well-known causes of the excess mortality. The exact pathophysiological cause of sudden death in schizophrenia is unknown, but it is likely that cardiac arrhythmia and respiratory abnormalities play potential role. Some antipsychotics may be associated with cardiovascular adverse events (e.g., QT interval prolongation) and lesions in specific brain regions, such as cerebella may be associated with respiratory abnormalities, suggesting that metabolic and brain dysfunction could lead to sudden cardiac death in patients with schizophrenia. However, exact knowledge regarding the association of these findings and schizophrenia is lacking. As subclinical hyperthyroidism has been linked with increased risk of cardiovascular disease and cerebella progressive atrophy has been observed in patients with schizophrenia, we propose in this paper that subclinical thyroid dysfunction and cerebella volume loss could be considered as new risk factor for sudden cardiac death in schizophrenia.

Mothers of children with cerebral palsy with or without epilepsy: a quality of life perspective.

PURPOSE: Disability in a child affects not only the child's life but also the family's life. The aim of our study is to verify the quality of life (QOL) of mothers of disabled children with cerebral palsy (CP) with epilepsy compared with non-epilepsy children evaluated in a Brazilian center. METHODS: Thirty mothers of disabled children participated in the study. The control group comprised of 18 healthy mothers of children without disabilities. All mothers agreed to participate in the study. They completed the evaluation forms of the SF-36 health survey, a well-documented, self-administered QOL scoring system. RESULTS: The results of our study support the premise that mothers of children with CP, as a group, have poorer QOL than mothers of not disabled children. CONCLUSIONS: We also observed that mothers of children with CP and epilepsy have poorer QOL than mothers of children with CP without epilepsy.

Serum magnesium: a clinical biomarker for sudden unexpected death in epilepsy? / Magnésio sérico: um biomarcador cerebral para morte súbita em epilepsia?

INTRODUCTION: Epilepsy is one of the most common chronic neurological disorder in the world and has a higher mortality rate than would be expected in a healthy population. One of the most related category of death is sudden unexpected death in epilepsy (SUDEP). Many risk factors have been related to SUDEP, but the mechanisms involved in its genesis is still unknown. OBJECTIVE: Here we describe one case of a patient with low serum magnesium levels that suffered of SUDEP. CONCLUSION: we discuss a possible cause-effect relation, suggesting that magnesium may be, in some cases, a biomarker of SUDEP.

INTRODUÇÃO: Epilepsia é uma das doenças neurológicas crônicas mais comuns, com uma elevada taxa de mortalidade quando comparada com a população saudável. Uma das principais causas de morte é a morte súbita em epilepsia (SUDEP). Muitos fatores de risco têm sido correlacionados com SUDEP, mas os mecanismos envolvidos na sua gênese são ainda desconhecidos. OBJETIVOS: será descrito um caso de um paciente com nível sérico de magnésio baixo que sofreu SUDEP. CONCLUSÕES: discutiremos uma possível relação de causa-efeito, sugerindo que o magnésio pode ser, em alguns casos, um biomarcador de SUDEP.

What are the similarities between stress, sudden cardiac death in Gallus gallus and sudden unexpected death in people with epilepsy.

Individuals with epilepsy are at higher risk of sudden unexpected death in epilepsy (SUDEP), responsible for 7.5% to 17% of all deaths in epilepsy. Many factors are current associated with SUDEP and possible effect of stress and cardiac arrhythmia are still not clear. Sudden death syndrome (SDS) in chickens is a disease characterized by an acute death of well-nourished and seeming healthy Gallus gallus after abrupt and brief flapping of their wings, similar to an epileptic seizure, with an incidence estimated as 0.5 to 5% in broiler chickens. A variety of nutritional and environmental factors have been included: but the exactly etiology of SDS is unknown. Studies had suggested that the hearts of broiler chickens are considerably more susceptible to arrhythmias and stress may induce ventricular arrhythmia and thus, sudden cardiac death. In this way, SDS in Gallus gallus could be an interesting model to study SUDEP.

Cardiorespiratory and electroencephalographic responses to exhaustive acute physical exercise in people with temporal lobe epilepsy.

We evaluated physiological and electroencephalographic responses during a cardiopulmonary exercise test (CPET) in people with epilepsy. Behavioral outcomes of people with epilepsy were also compared with those of healthy controls. Thirty-eight subjects (19 people with epilepsy and 19 controls) participated in this study. Poor outcomes in the behavioral analyses (habitual level of physical activity and quality of life) were observed in the people with epilepsy. With respect to the CPET, V.O(2max) (14.6%) and V.O(2) at anaerobic threshold (16.1%) were significantly lower in the epilepsy group than in the control group. Although not statistically significant, a decrease in the number of epileptiform discharges was observed between the rest state and exercise (82%) and between the rest state and recovery period (74%). In conclusion, the lower aerobic fitness in people with epilepsy observed may be associated with their sedentary habits. Moreover, our findings reinforce the hypothesis that exhaustive exercise is not a seizure-inducing factor.
