[New results of neuroscience research – the background of symptomatological and etiological diversity of mental disorders]

OSVÁTH Péter

[Nowadays, the focus of genetic, neurobiological, neuropsychological and psychosocial research is on a more accurate discovery of the etiology of mental illnesses, especially with regard to the role and complex interactions of certain risk factors. It is increasingly challenging to interpret the results of different aspects and methodologies in a coherent theoretical framework, as this can only lead to a more accurate understanding of the complexity and mechanism of the psychiatric disorders. The main aim of this paper to overview recent studies on etiological background of mental disorders and to present the most important aspects of the Research Domain Criteria (RDoC) system. Review of reports from comprehensive studies published in the most important psychiatric journals over the past five years summarizing new findings on the etio­logy of mental disorders. Although current classifications indicate that mental disorders are strictly distinct diagnostic categories, new findings suggest that these marked differences in symptomatic, genetic, and neurobiological backgrounds are not detectable, as many mental disorders have been identified as having common molecular genetic risk factors, which may indicate common neurobiological pathomechanisms. Research results support the need for a rethinking of psychiatric nosology on an etiological basis and represent an important step forward in the more accurate exploration of the neurobiological background factors of mental disorders and thus in the development of more targeted therapeutic approaches. The development of the RDoC system can be a great help in this, as this dimensional approach offers the possibility of integrating the - often diffuse or even contradictory - neuroscientific research findings into a unified theoretical framework for the etiology, nosology and treatment of mental disorders. ]

[The role of stress management in the care of hypertension and the treatment of cardiovascular disease]

SOMOGYI Éva, KISS Zoltán, STAUDER Adrienne

[The aim of this paper is to give an overview of the relationship between stress and hypertension and cardiovascular diseases, furthermore to introduce an evidence based stress management intervention available in Hungary. The correlation between cardiovascular disease and psychosocial factors (including concomitant mental disorders as well as personality traits or the effect of social environment) has been established in numerous studies aimed at investigating pathogenesis or various clinical endpoints. The 2016 Guidelines of the European Society of Cardiology include the assessment and the management of psychosocial problems with behavioral medicine interventions as a I.A level recommendation. The implementation of these guidelines in everyday clinical practice is crucial to decrease cardiovascular risk. This involves the training of health care professionals, the facilitation of multidisciplinary collaboration and the integration of behavioral intervention into everyday care. The Williams Life Skills (WLS) program is an evidence based behavioral medicine intervention aiming to improve stress management and communication skills which implemented internationally and also available all over Hungary. It involves the learning of simple coping strategies that facilitate the successful management of every day psychosocial stress situations and the self-conscious reduction of bodily and psychological tensions. In cardiovascular disease, this improves quality of life and survival. The WLS program is especially recommended for healthcare workers to decrease the negative health consequences of their high stress load and to prevent burnout. Stress may affect both doctors and patients during their interactions. Bálint groups have a positive impact on the physician-patient collaboration and help to reduce burnout by improving the understanding of the diseases from a more complex approach.]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Suicide endangering elderly people: risk factors, prevention and care]

BARACZKA Krisztina

[According to the data of the Hungarian Central Statistical Office (HCSO), the Hungarian citizens aged over 65 represented in 2001 11.8%, 2011 13.2% and 2019 19.3% of the total population. Providing services for aging (>60 years), aged (>75 years), very old (>90 years) and Matusalem (>100 years) individuals burdens heavily the health system and the socio-economic sector. Maintaining these people’s physical and mental health and self-perceived well-being is a pre-eminently important task. According to the World Health Organization (WHO) statistics based on data providing countries, the number of suicides committed in the population aged 60-79 has risen approximately by 21% between 1987 and 2006. The suicide rate in Hungary has decreased steadily and significantly since 1980 (4809 in 1980, 1656 in 2018, i.e. a decrease of 66%). Thus since 2018, Hungary is not among the top three countries in Europe and the top 15 in the world. However, the number of completed suicides and suicide attempts remains high and shows rising tendency in the elderly. Preventing suicide, exploring the risk factors and caring patients after attempted suicide we need to analyse thoroughly and disseminate widely the results of the recent researches. In this study, we re­viewed international and domestic literature data to find answers primarily to prevention issues. ]

[Minority students in Hungarian medical training]

SZÉL Zsuzsanna

[General health of minority people is usually worse than that of their majority peers and they often expe rience discrimination in the healthcare system. According to international literature, physicians belonging to any minority group are more likely to care for other mi nority people, therefore they may play a key role in reducing healthcare inequities. Anonymous, online questionnaire was distributed to medical students of the four Hungarian universities with medical schools (response rate was 8.86%). In this paper, we analyze our collected data about perceived discrimination with descriptive statistical methods. Results of confirmative statistical analyses (statistical tests) were considered exploratory in nature. 29.6% of respondents self-identified as a member of any minority. 63.0% of minority students and 53.8% of women indicated that they realized discriminated or were harassed in the last 12 months, meanwhile, 37.8% of non-minority students and 31.9% of males have experienced discrimination. Dis­cri­mi­na­tion related to ethnic origin, sexual orientation and disability are regarded as the most widespread forms of discrimination according to our respondents. Students are most likely to say that there is no age related discrimination on the grounds of age – both being under 30 years old (12.0%) and being over 55 (8.6%). Being the member of any minority group seems to have no effect on student’s/ one’s opinion how widespread the forms of dis crimination are. Minority students are more comfortable to work with a member of another minority. However male students feel more uncomfortable to work with a member of sexual or gender minorities compared to female counterparts. Mi­no­rity students tend to be more critical to the universities’ efforts to enhance diversity. Minority students and females may play a key role in reducing discrimination in medical training and in the healthcare system and in providing high-quality care for individuals who belong to any minority. Although there are more females than males in medical training they still report higher occurrence of perceived discrimination. However, it is important to emphasize the low response rate in our study, which does not allow us to draw any general conclusions.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

[Background – Contemporary neuroimaging methods disclosed structural and functional cerebral abnormalities in idiopathic generalized epilepsies (IGEs). However, individual electrical (EEG) abnormalities have not been evaluated yet in IGE patients. IGE patients were investigated in the drug-free condition and after 3-6 month of antiepileptic treatment. To estimate the reproducibility of qEEG variables a retrospective recruited cohort of IGE patients was investigated. 19- channel resting state EEG activity was recorded. For each patient a total of 2 minutes EEG activity was analyzed by LORETA (Low Resolution Electromagnetic Tomography). Raw LORETA values were Z-transformed and projected to a MRI template. Z-values outside within the [+] 1. In drug-free condition, 41-50% of IGE patients showed abnormal LORETA values. 2. Abnormal LORETA findings showed great inter-individual variability. 3. Most abnormal LORETA-findings were symmetrical. 4. Most maximum Z-values were localized to frontal or temporal cortex. 5. Succesfull treatment was mostly coupled with disappearence of LORETA-abnormality, persistent seizures were accompanied by persistent LORETA abnormality. 1. LORETA abnormalities detected in the untreated condition reflect seizure-generating property of the cortex in IGE patients. 2. Maximum LORETA-Z abnormalities were topographically congruent with structural abnormalities reported by other research groups. 3. LORETA might help to investigate drug effects at the whole-brain level.]

[Systemic thrombolysis and endovascular intervention in postpartum stroke]

BERECZKI Dániel Jr., NÉMETH Beatrix, MAY Zsolt, SZAKÁCS ZOLTÁN, GUBUCZ István, SZIKORA István, SZILÁGYI Géza

[Introduction - There are no previously published cases about intravenously applied recombinant tissue plasminogen activator in acute ischemic stroke during puerperium. Case presentation - We report a 40-year-old woman with postpartum acute ischemic stroke caused by multiple cervical artery dissections treated by systemic thrombolysis and endovascular intervention. Discussion - There are only limited data regarding thrombolytic treatment in acute stroke during pregnancy and puerperium. Current acute stroke treatment guidelines - while considering pregnancy as a relative exclusion criterion - do not deal with the postpartum state. Conclusion - As the condition is rare, randomized controlled trials are not feasible, therefore further reports on similar cases could eventually help us suggest guidelines or at least propose recommendations for the acute thrombolytic treatment of strokes occurring in pregnancy and puerperium.]

[Sleep disordered breathing and epilepsy: relationships and therapeutic considerations]

FALUDI Béla, BÓNÉ Beáta, KOMOLY Sámuel, JANSZKY József

[The importance of the sleep related breathing disorders (obstructive sleep apnea syndrome, central sleep apnea, and Cheyne-Stokes breathing) in the pathophysiology crebro- and cardiovascular disorders is well known. The relationship of sleep related breathing abnormalities and epilepsy is also important but underestimated in the daily practice. The relation is bidirectional. The breathing abnormalities in sleep may play important role in generating epileptic seizure, but the adverse effect of seizure and antiepileptic therapy (generation of apneas and hypopneas) may worsen the seizure control. The effect of new therapies (vagal nerve and deep brain stimulation) on the sleep architecture and sleep disordered breathing must be examined and discussed. Here we present a brief case of epileptic patient with deep brain stimulation therapy on sleep as well. The examination of the sleep related breathing abnormalities in epilepsy patient may help improve the effectiveness of antiepileptic therapy.]

[Attachment as a predictor of risk for eating disorders on a representative hungarian adult sample]

SZALAI Dömötör Tamás, CZEGLÉDI Edit

[Background and purpose – Many studies confirm the relationship between attachment disturbances and (the severity of) eating disorders, however among them only one Hungarian study can be found. The exact predisposing traits of attachment and the strength of relationship is still uncleared. Our aim was to explore these aspects. Methods – Study was based on a cross-sectional nationally representative survey, called „Hungarostudy 2013” (N=2000, 46.9% males, mean age 46.9 years, SD=18.24 years). Measures: Sociodemographic and self-reported anthropometric data (weight and height), short Hungarian version of Relationship Scale Questionnaire, SCOFF questionnaire and short Hungarian version of Beck Depression Inventory. Results – The frequency of risk for eating disorders (anorexia or bulimia nervosa) was 3.9% (N=76) among the respondents (N=1860). Attachment anxiety was significantly higher in the risk for eating disorders group (t(1888)=-3.939, p<0.001), and significantly predicted the risk for eating disorders after adjusting for the potential background variables (OR=1.09, p=0.040). Detachment was not a significant predictor of risk for eating disorders (OR=0.98, p=0.515). Younger age (OR=0.97, p<0.001), higher level of depression (OR=1.09, p<0.001) and higher body mass index (OR=1.08, p<0.001) were also significant cross-sectional predictors of risk for eating disorders. The explained variance of the model was 10.7%. Conclusion – The study supported, that higher attachment anxiety is associated with the increased risk of eating disorders, with a possible therapeutic relevance. Assessment of attachment’s further aspects and creating multivariable models are required for more thorough understanding and optimising of intervention points.]
