Abstract
Creativity is a particularly complex entity that can be best conceptualized along dimensions of opposite polarities. It can simultaneously be considered as a phenomenon that comprises a multitude of processes but also be interpreted as a complex construct which indeed does not have a uniformly accepted definition despite extensive literature on creativity. Creativity researchers of various approaches offer alongside methodological diversity a vast array of paradigms and definitions, leading, on the other hand, to contradictions of results. Nevertheless, the concept of creativity is to be maintained in the sense that it encompasses the ability to produce innovatively original, valuable, adaptive solutions breaking with pre-existing categories and developing unconventional alternatives. Since creativity cannot definitely be subject of scientific investigations as an overarching entity and its essence has not been grasped so far, some of its components can be measured and defined such as specific cognitive processes (divergent and convergent thinking, remote associations, conceptual expansion, working memory), motivational factors, emotional/affective conditions or personality traits considered as predictors of creative performance (schizotypal, autistic spectrum traits). Even though definitional inconsistencies persist, gradually neurobiological approaches have become the main issue of creativity research. Recently, the analysis of brain network activity applying methods of electrophysiology and brain imaging seems to promote the understanding of the functional localization of creative performance. Certain brain regions were initially identified as correlates of creativity, such as lateral prefrontal cortex, inferior parietal lobe, insula, striatum. More recent studies emphasize the activation and effective functional connectivity of large brain networks (default mode network, frontoparietal executive control, and others) as well as highlight the importance of their brain and neurochemical substrate (gray matter volume, white matter integrity, dopamine), connecting with cognitive processes of opposite style (flexibility versus persistence). While this paradigm seems to converge toward the delineation of a coherent neurobiological model of creativity, obviously we would not infer the essence of such a complex phenomenon from a simplified sub-process.

Abstract
INTRODUCTION Due to the high rate of mortality, recognizing the contributing factors of alcohol-related delirium tremens (DT), which is the most severe form of alcohol withdrawal state (AWS) is pivotal in clinical settings. Previous studies suggested relationship between seasonality and other types of delirium; however, to our knowledge, this is the first empirical study which examined the role of seasonality in DT in alcohol dependence syndrome (ADS). METHODS A retrospective study was undertaken between 2008 and 2015; medical records of 1,591 patients were included, which yielded 2,900 hospital appearances. Three groups were formed based on the ICD-10 diagnoses: ADS, AWS, and DT. The characteristics of the groups were analysed with one-way ANOVA and χ2 tests. Multinomial logistic regression was used to explore the potential predictors of DT, including seasonality. RESULTS The highest incidence of DT was in spring (36.8%; χ2 (3) = 27.666; p < 0.001), especially in March (13.9%; χ2 (11) = 33.168; p < 0.001). Spring, higher mean age, higher presence of comorbid somatic disorders, and lower occurrence of comorbid psychiatric disorders were significant predictive variables for DT with the control of socio-demographic and clinical variables. CONCLUSIONS The present study revealed that spring, especially March is a critical period in temperate climate zone regarding DT. This can be interpreted as a late winter effect since the temperature is lower in this month compared to other spring months. Furthermore, higher age and the occurrence of comorbid somatic disorders can be considered as risk factors in case of DT. These results support the need of further clinical studies to better understand the impact of seasonality on DT.

Abstract
AIMS Higher levels of externalizing characteristics, i.e. impulsivity, novelty seeking and aggression, could contribute to the development, progression and severity of alcohol use disorder (AUD). The present study aims to explore whether these externalizing characteristics together have a potential group-forming role in AUD using latent profile analysis (LPA). METHODS Externalizing characteristics of 102 AUD patients were analyzed using LPA to explore the group-forming role of externalizing symptoms; groups were compared in terms of demographic and alcohol-related variables, indices of psychopathological, depressive and anxiety symptom severity. RESULTS LPA revealed and supported a two-group model based on externalizing symptoms. The group with higher levels of externalizing symptoms showed significantly elevated levels of alcohol-related and anxio-depressive symptoms. CONCLUSIONS Externalizing characteristics converge and have a group-forming role in chronic AUD, and are associated with a more severe form of AUD. By making the diagnostic category less heterogeneous, these different subtypes within AUD may provide aid in tailoring treatments to patients' specific needs.

Abstract
INTRODUCTION In the recent research and interpretation of the genetical-biological and environmental-social factors shaping psychosexual development, in addition to scientific arguments, more and more ideological and political aspect have received unfortunate emphasis. OBJECTIVE Since the literature investigating the development of gender identity and gender orientation has not only increased, but also polarized, it is timely to look at the scientific exchange of ideas and debates among the differing positions. METHOD Exploring the significance of genetic, biological and social factors involved in the development of gender identity and gender orientation based on international literature data. RESULTS Based on the current state of science it can be concluded that, in addition to the indisputably marked genetic-biological factors, education and social patterns, as well as the extremely complex environmental and media-related influence with its variable intensity and diverse emotional content also play a significant role in the psychosexual development. This is supported, among other observations, by the data indicating that homoerotic behavior is more common in people raised by same-sex couples. CONCLUSION As psychosexual development is determined jointly by both genetic-biological and social factors (like education, media etc), belonging to a sexual minority group is not a choice, not the result of a personal decision. Therefore, any kind of discrimination in this regard is unacceptable. Further scientific studies are necessary to answer a large number of questions that still remain open.

Abstract
BACKGROUND Multiple psychological factors of suicidal behaviour have been identified so far; however, little is known about state-dependent alterations and the interplay of the most prominent components in a suicidal crisis. Thus, the combined effect of particular personality characteristics and decision-making performance was observed within individuals who recently attempted suicide during a major depressive episode. METHODS Fifty-nine medication-free major depressed patients with a recent suicide attempt (within 72 h) and forty-five healthy control individuals were enrolled in this cross-sectional study. Temperament and character factors, impulsivity and decision-making performance were assessed. Statistical analyses aimed to explore between-group differences and the most powerful contributors to suicidal behaviour during a depressive episode. RESULTS Decision-making and personality differences (i.e. impulsivity, harm avoidance, self-directedness, cooperativeness and transcendence) were observed between the patient and the control group. Among these variables, decision-making, harm avoidance and self-directedness were shown to have the strongest impact on a recent suicide attempt of individuals with a diagnosis of major depressive disorder according to the results of the binary logistic regression analysis. The model was significant, adequately fitted the data and correctly classified 79.8% of the cases. CONCLUSIONS The relevance of deficient decision-making, high harm avoidance and low self-directedness was modelled in the case of major depressed participants with a recent suicide attempt; meaning that these individuals can be described with the myopia for future consequences, a pessimistic, anxious temperament; and a character component resulting in the experience of aimlessness and helplessness. Further studies that use a within-subject design should identify and confirm additional characteristics specific to the suicidal mind.

Abstract
AIMS Non-invasive and simultaneous recording of gastrointestinal (GI) activity during stress induction is still an unexplored field. In our previous investigation, the stress-induced alteration of the gastrointestinal tract was explored in rats. Our aims were to expand our previous rat experiment and to induce stress response in rats (Study 1) and humans (Study 2) to detect the GI tract activity, heart rate and body temperature. MATERIALS AND METHODS In the preclinical sample, acute stress was induced by immobilization in Sprague-Dawley rats (N = 10). Acute stress response was generated by the Trier Social Stress Test among healthy volunteers (N = 16). Detection of acute stress was measured by using smooth muscle electromyography, which recorded the myoelectric waves of the gastrointestinal tract (stomach, ileum and colon) simultaneously with heart rate and body temperature in rats and humans. KEY FINDINGS The myoelectric waves of the stomach, the cecum and the ileum increased during immobilization in rats, rising in parallel with heart rate and the dermal temperature of the abdominal surface. The same alterations were found during the stress period among humans, except in the case of the colon, where no change was detected. SIGNIFICANCE The crucial role of the GI tract in stress response was revealed by translating the outcome of basic research into human results. The similar GI alterations during stress in rats and humans underpin the robustness of our findings. In summary, our preliminary translational-based study can serve as an appropriate basis for further human studies.

Abstract
BACKGROUND Although the Clinical Institute Withdrawal Assessment for Alcohol - Revised (CIWA-Ar) is a gold standard tool for the clinical evaluation of alcohol withdrawal syndrome (AWS), a systematic analysis using the total scores of the CIWA-Ar as a means of an objective follow-up of the course and treatment of AWS is missing. The aims of the present study were to systematically evaluate scientific data using the CIWA-Ar, to reveal whether the aggregated CIWA-Ar total scores follow the course of AWS and to compare benzodiazepine (BZD) and non-benzodiazepine (nBZD) therapies in AWS. METHODS 1054 findings were identified with the keyword "ciwa" from four databases (PubMed, ScienceDirect, Web of Science, Cochrane Registry). Articles using CIWA-Ar in patients treated with AWS were incorporated and two measurement intervals (cumulative mean data of day 1-3 and day 4-9) of the CIWA-Ar total scores were compared. Subgroup analysis based on pharmacotherapy regimen was conducted to compare the effectiveness of BZD and nBZD treatments. RESULTS The random effects analysis of 423 patients showed decreased CIWA-Ar scores between the two measurement intervals (BZD: d = -1.361; CI: -1.829 < δ < -0.893; nBZD: d = -0.858; CI: -1.073 < δ < -0.643). Sampling variances were calculated for the BZD (v1 = 0.215) and the nBZD (v2 = 0.106) groups, which indicated no significant group difference (z = -1.532). CONCLUSIONS Our findings support that the CIWA-Ar follows the course of AWS. Furthermore, nBZD therapy has a similar effectiveness compared to BZD treatment based on the CIWA-Ar total scores.

Abstract
Depending on affinity, attitude, preference, understanding, and mental state, music can influence emotions, mood, motivation, psychomotor, cognitive, and spiritual functions in the receptive person. It is presumed that a given music may reflect the actual psychic condition of the composer and, if applicable, the nature of the chosen topic to be characterized. However, extreme situations may emerge from these components i.e. the music might overshoot the frontiers of normal psychological phenomena and 'heavy mental' psychopathological symptoms or syndromes may appear in it. Present search restricts the wide range of music categories to the classical one (instrumental and vocal, opera included) and attempts to screen for such 'heavy mental' psychopathological signs beside mentioning the slighter symptoms. Phenomena of amnesia, dementia/delirium, mental retardation, biased perception, chemical/behavioural addiction, delusion, misidentification, mania, depression, suicide, anxiety, obsession-compulsion, conversion, disso - ciation, para/hyper/insomnia, sexual and personality disorders are listed as examples from the wide repertoire. The figure of the 'fool' and the topic of 'madness' (in general, and folia, tarantella) are mentioned as well as the appearance of some behavioural traits ('seven deadly sins'), feigning psychic/somatic states, pathological lying, mutism, stutterism, famous oracles, mesmerism, and employing magic or various potions. Mad scenes as psychotic conditions (often tran - sient if due to psychotrauma from romantic love) occur in many operas. However, quite a few of them have been written by Donizetti. Considering his life, behaviour and composing features, the question arises about Donizetti's ailment: was it mood disorder, Barbaja, or luetic derailment?

Abstract
BACKGROUND AND AIMS The importance of personality characteristics in the diagnosis and treatment of gambling disorder (GD) and alcohol use disorder (AUD) is often highlighted in scientific literature. This study aimed to test predictions about the associations of temperament and character in chronic AUD patients with comorbid GD symptoms and without them. METHODS Chronic AUD patients enrolled from an inpatient clinic were divided in two groups based on cluster analysis, AUD patients with (AUD + GD group: n = 30) and without (AUD group: n = 68) GD symptoms. Severity of GD symptoms and personality dimensions (Cloninger's Temperament and Character Inventory Revised, TCI-R) were assessed. Associations of tested variables were analysed with analysis of covariance, one-sample and independent sample t-tests. RESULTS GD symptoms proved to be a clustering factor in terms of personality, where AUD + GD group expressed a more maladaptive personality profile. Compared to Hungarian normative TCI-R scores, both patient groups showed elevated levels of Harm Avoidance and Novelty Seeking with lower scores of Self-directedness, while the AUD + GD group scored lower on Persistence and Cooperation as well. The AUD + GD group reported significantly higher levels of Harm Avoidance, with lower scores of Reward Dependence compared to the AUD group. DISCUSSION Comorbid GD symptom severity is an important factor in chronic AUD, where AUD patients with comorbid GD symptoms exhibited a more maladaptive personality constellation than singular AUD patients. These emphasize the need of special attention for comorbid GD symptoms in AUD, since treatment recommendations and prognosis for them may also differ.

Abstract
Inflammatory processes seem to play a role in neurodegenerative diseases such as Alzheimer's disease (AD). Local inflammatory mechanisms can affect to neurotoxicity, interfere with beta amyloid expression and metabolism. The increased production of amyloid precursor protein eventually leads to the deposition of amyloid beta. Interferon (INF) gamma plays a pivotal role in the inflammatory processes.The aim of this study was to evaluate the putative role of INF gamma +874 T/A polymorphism and its association with apolipoprotein E (ApoE) 4 allele in AD.One hundred and eighty nine healthy controls (HC) and 191 patients with AD were involved in this study. The probable AD patients were diagnosed by NINCDS-ADRDA criteria. The DNA was extracted from whole peripheral blood. INF gamma +874 T/A and ApoE polymorphisms were assessed by the PCR based method.ApoE 4 allele occurrence in AD was 27% compared to 9% in HC. There were no statistically significant differences in the distribution of INF gamma genotypes (AD: A/A:30.9%, T/A:46.1%, T/T:23.0%; HC: A/A:21.7%, T/A:54.5%, T/T:23.8%, p=0.110) or alleles. The INF gamma A/A genotype was more frequent in the presence of ApoE 4 allele in AD (13.6%) than in the HC (4.8%).Our results confirm the role of ApoE 4 allele in AD. However, no association was found between the INF gamma +874 T /A polymorphism and AD. The simultaneous occurrence of ApoE 4 allele and one of the INF gamma genotypes presumably can not modify the risk for AD. (ETT 198/04/2006 and OTKA K 60589/2006).

Abstract
BACKGROUND AND AIMS Alcohol use disorder (AUD) and problem gambling are highly comorbid disorders. This study aims to explore the role of four aspects of impulsivity (trait concept of impulsivity, choice impulsivity, impulsive aggression and response inhibition/decision-making) in long-term chronic AUD patients with and without problem or pathological gambling symptoms. METHODS Cognitively intact chronic AUD patients were enrolled with (n = 32) and without (n = 71) problem gambling symptoms in an inpatient clinic for chronic alcohol users. Multiple facets of impulsivity, cognitive ability, psychopathological symptoms, alcohol and gambling severity were measured. RESULTS Chronic AUD patients with gambling disorder symptoms showed longer lifetime alcohol consumption, more severe alcohol use and higher psychopathological symptom severity than AUD patients without gambling symptoms. Gambling severity correlated with overall trait impulsivity, but not with choice impulsivity, impulsive aggression or cognitive impulsivity with controlling for lifetime alcohol consumption, lifetime alcohol use and psychopathological symptom severity. High trait impulsivity and non-planning was associated with comorbid gambling symptoms in AUD patients, which was independent of the level of intelligence, age and psychopathological symptoms. CONCLUSION Comorbid gambling disorder symptoms in chronic AUD was connected to more severe alcohol-related variables. Higher trait impulsivity was also linked with gambling disorder symptoms in patients with chronic AUD. This accents the need of special focus on comorbid GD symptoms in AUD, since prognosis and treatment for them may vary.

Abstract
Trace elements are found in the living organism in small (trace) amounts and are mainly essential for living functions. Essential trace elements are in humans the chromium (Cr), cobalt (Co), copper (Cu), fluorine (F), iodine (I), iron (Fe), manganese (Mn), molybdenum (Mo), selenium (Se), zinc (Zn), and questionably the boron (B) and vanadium (V). According to the biopsychosocial concept, mental functions have biological underpinnings, therefore the impairment of certain neurochemical processes due to shortage of trace elements may have mental consequences. Scientific investigations indicate the putative role of trace element deficiency in psychiatric disorders such in depression (Zn, Cr, Se, Fe, Co, I), premenstrual dysphoria (Cr), schizophrenia (Zn, Se), cognitive deterioration/de-mentia (B, Zn, Fe, Mn, Co, V), mental retardation (I, Mo, Cu), binge-eating (Cr), autism (Zn, Mn, Cu, Co) and attention deficit hyperactivity disorder (Fe). At the same time, the excess quantity (chronic exposure, genetic error) of certain trace elements (Cu, Mn, Co, Cr, Fe, V) can also lead to mental disturbances (depression, anxiety, psychosis, cognitive dysfunction, insomnia). Lithium (Li), being efficacious in the treatment of bipolar mood disorder, is not declared officially as a trace element. Due to nutrition (drinking water, food) the serum Li level is about a thousand times less than that used in therapy. However, Li level in the red cells is lower as the membrane sodium-Li countertransport results in a Li efflux. Nevertheless, the possibility that Li is a trace element has emerged as studies indicate its potential efficacy in such a low concentration, since certain geographic regions show an inverse correlation between the Li level of drinking water and the suicide rate in that area.

Abstract
Nalmefene is approved for as-needed pharmacological treatment in alcohol use disorder (AUD) by the European Medicines Agency. While the cellular effects of nalmefene have been thoroughly investigated, data are very limited on how this agent influences neural signals associated with inhibitory control and the visual analysis of environmental cues. This double-blind crossover study assessed the behavioral and neural effects of acute nalmefene administration in patients diagnosed with AUD. In experiment 1, we validated our experimental paradigm (electroencephalography combined with a modified Go/NoGo task using images of alcoholic and nonalcoholic drinks as prime stimuli) in 20 healthy adults to ensure that our protocol is suitable for assessing the behavioral and neural aspects of executive control. In experiment 2, we recruited 19 patients with AUD, and in a double-blind crossover design, we investigated the effects of nalmefene versus placebo on task performance (response accuracy, the sensitivity index, and reaction times), visual responses to appetitive cues (occipital P1, N1, and P2 components), and electrophysiological markers of conflict detection and response inhibition (frontal N2 and P3 waveforms). Under placebo, patients produced faster reaction times to alcohol-primed Go stimuli, an effect that was weak despite being statistically significant. However, the effect of alcoholic cues on the speed of response initiation disappeared after receiving nalmefene. We found no placebo versus nalmefene difference regarding our patients’ ability to accurately inhibit responses to NoGo stimuli or for occipital and frontal event-related potentials. Our results suggest that nalmefene might be potent in reducing the vigor to act upon alcoholic cues in AUD patients, but this effect is most probably mediated via subcortical (rather than cortical) neural circuits.

Abstract
The ATP-binding cassette, sub-family A, member 7 (ABCA7) gene has been identified as a strong genetic risk locus for Alzheimer's disease (AD). Our case-control study (416 AD patients and 302 controls) provides further data on the rs3752246 polymorphism in AD in the Hungarian population that has not been investigated so far regarding the ABCA7 gene variants. A modest, marginally significant association of the G allele containing genotypes with AD was observed (p = 0.054). In line with the previous results in other populations, the G allele carriers had an increased risk for developing AD considering C/C genotype as reference category.

Abstract
Abstract: Introduction and aim: The available literature and protocols have unequivocally suggested that the Clinical Institute Withdrawal Assessment of Alcohol, Revised is a psychometric scale for identifying and following the signs of alcohol withdrawal. However, there has not been any validated tool for the identification of withdrawal symptoms in Hungarian general hospital settings. The aim of the present study was to evaluate the validity and the reliability of the Hungarian version of this scale among patients hospitalized with alcohol withdrawal syndrome. Method: The translation of the scale into Hungarian was done by ‘back translation’ method, followed by testing the face validity. The empirical phase was performed in the Department of Psychiatry, University of Szeged. Patients admitted with alcohol withdrawal syndrome (n = 30) were recruited from the inpatient units of the clinic. Clinical Institute Withdrawal Assessment of Alcohol, Revised and Clinical Global Impression – Severity Scale were recorded every two days. Statistical comparisons of data were performed with repeated-measures ANOVA. Cronbach’s alpha, item-total correlation, convergent and discriminant validity were determined. Results: Significant decrease of the total scores of Clinical Institute Withdrawal Assessment of Alcohol, Revised and Clinical Global Impression – Severity Scale was observed between the six measurements (F = 202.46, p<0.001; F = 503.04, p<0.001). Cronbach alpha values were above 0.7 during the first 3 measurement days. The withdrawal and severity scores recorded the same day showed positively significant correlations (>0.45). Conclusion: Our findings demonstrate that the Clinical Institute Withdrawal Assessment of Alcohol, Revised is a reliable and valid psychometric tool for the detailed analysis of withdrawal symptoms in Hungarian general hospital settings.

Abstract
Abstract: Depending on the personal attitude toward a given style and performance, music can influence mental activities such as emotion, mood, motivation, psychomotor tempo and possibly cognition. Experimental data indicate that music can alter physiological parameters of somatic functions (blood pressure, heart rhythm, peripheral blood flow, respiration). However, efforts are taken in medicine and neuroscience to decipher brain physiological and morphological correlates in processing or performing music. Modern imaging techniques brought a significant advance in this respect. It appears that there is no single music center in the brain, but depending on the components (melody, rhythm) of the music, more cerebral areas with strong network connections participate in that. Important regions are the upper temporal area (primary, secondary, tertiary auditory cortex), and parts of the frontal and parietal lobes, limbic system, and cerebellum. Beyond the above aspects, medicine joins to music in the field of music therapy. Meta-analyses of controlled studies show that music can be suitable to decrease stress, anxiety, and depression in various disease groups (cardiovascular, oncological, mental) and in medical examinations (surgical, urological, cardiac catheterization). Improvements were observed in motor, cognitive and psychosocial functions after music interventions in stroke rehabilitation. The links between mood disorders and creativity in music belong to medicine as well, where eminent composers can be mentioned, and also the examples of scholar and practitioner physicians playing or composing music superbly.

Abstract
Current writing is a tribute of respect, on the occasion of his 80th birthday, to professor László Tringer. In a somewhat unusual way, instead of a bouquet of 80 flowers, a bunch of 80 limericks is presented for him with compliments. The origin of the idea is that professor Tringer himself also writes poems and rhymes in his leasure time. The celebrated professor is an eminently recognized person in the profession, and he is one of the founding fathers of modern psychiatry in Hungary. After receiving the diploma in medical sciences, he has obtained one in psychology and in theology as well. Beside other qualifications he has specializations in psychiatry, neurology, clinical pharmacology, clinical psychology, psychotherapy, addictology and geriatry. Thanks to the providence, the author of the current writing has many common and unforgettable experiences with him. The 80 limericks on the one hand refer to these mutual memories and on the other hand reflect the author's subjective observations on some areas of the society, life situations, character depictions, psychiatry, other medical professions, mental functions, the brain's structural and neurochemical features, and several hints for life conduct. It is assumed that professor Tringer may not necessarily agree with all of these opinions. Nevertheless, these might serve as a basis for further mutual (and for him now over 80 years) inspiring consultations and intellectual adventures.

Abstract
BACKGROUND The significance of decision-making in suicidal behaviour is often highlighted; however, the performance of persons in suicide crisis is unknown. This study aimed to explore the comprehensive decision-making profile of depressed patients following a suicide attempt. METHODS Decision-making was measured by reward- ("ABCD") and punishment- ("EFGH") sensitive versions of the Iowa Gambling Task (IGT) in 59 medication-free depressed patients within 72 h after a suicide attempt and in 46 healthy control subjects. Severity of depressive symptoms was assessed in the patient group by the Hamilton Depression Rating Scale. RESULTS Performance of the two groups differed significantly on the IGT ABCD, while a trend towards significant differences was seen on the IGT EFGH. Severity of depressive symptoms did not affect the depressed participants' decision-making performance. LIMITATIONS Subjects were not matched for years of education. Administration of the IGT ABCD and IGT EFGH was not counterbalanced. Methods of suicide attempts and history of previous attempts were not collected. CONCLUSIONS Individuals with a recent suicide attempt showed decision-making dysfunction on both IGT versions. However, on the EFGH, the overall difference between groups was not significant, depressed participants' performance remained poor during all blocks. Their behaviour reflected a focus on best immediate possible outcomes, not regarding future adverse consequences. This could be a result of psychological and cognitive alterations which modulate suicidal behaviour independent from mood. Further longitudinal studies should verify this possibility. Investigation of state-dependent neuropsychological characteristics of suicidal behaviour might be essential for detecting acute suicidal crisis.

Abstract
Mental flexibility enabling shifts from the usual prepotent behaviour to new strategies and solutions is a significant factor in the successful adaptation to the changing environment. Components of mental flexibility comprise attention, salience detection, inhibition, working memory and switch processes which can be measured by neurocognitive tests. Data derived from examinations by the methods of cognitive neuroscience can be compared to the features, observed under resting state and during task performance, of brain structures and functions. Studying central nervous system correlates of mental flexibility by imaging, neurobiological, and pharmacological techniques revealed that certain cerebral regions (prefrontal cortex, anterior cingulate and insula, striatum, inferior parietal lobule) with their network connectivities, and some neurotransmitters (e.g. dopamine) have profound roles in this respect. Flexibility shares some similarities with artistic/scientific/everyday creativity and openness as a personality trait and this is also reflected in neurobiological parameters. According to precedents in art history, the public reception and acceptance of nonconform avant-garde artistic products are also dependent on flexibility and openness. Alterations of mental flexibility have been found in diseases (psychiatric and others), and in stress situations. Although flexible switch is generally considered as positive and beneficial, under certain conditions advantages might arise from keeping stability maintaining customs, conventions, and traditions.

Abstract
BACKGROUND AND AIMS Gambling disorder (GD) and alcohol use disorder (AD) have similar features, such as elevated impulsivity and decision-making deficits, which are directly linked to relapse and poor therapeutic outcomes. Our aim was to assess decision-making characteristics in GD and AD patients compared to healthy controls (HC) based on one of the most frequently used measures of decision-making: the Iowa Gambling Task (IGT). METHODS In our systematic literature search of three databases, we identified 1198 empirical articles that mentioned decision-making deficits with the use of the IGT in patients diagnosed with either AD or GD. Possible effects were calculated using meta-analysis. In the end, 17 studies (including 1360 participants) were suitable for inclusion in the meta-analysis reporting data for 23 group contrasts. RESULTS The random effects estimate indicated impaired IGT performance in both AD patients (N=500; d=-0.581, CI:-89.5<δ<-26.6%) and an even greater deficit in GD patients (N=292; d=-1.034, CI:-156.1<δ<50.7%) compared to HCs. Sampling variances were calculated for both AD (v1=0.0056) and GD groups (v2=0.0061), from which the z-score was calculated (z=-21.0785; p<0.05), which indicates a statistically significant difference between AD and GD groups. No significant moderating effects of age, gender or education were found. CONCLUSIONS There is enough evidence to support that decision-making deficit associated with addictive disorders, and that the deficit is more expressed in gambling disorder than in alcohol use disorder. Impaired decision-making plays an important part in poor therapeutic outcomes, thus provides a promising opportunity for cognitive intervention.

Abstract
Suspicious thinking in given situations can be useful and helps the adaptation as events occurring in the world also corroborate this. Factors participating in the development of paranoia can be listed as psychodynamic (projection), salience attributional, neurobiological (dopamine), impaired perceptual (hearing loss), sociocultural (minority, pseudocommunity), self-esteem (worrying, depression, mania), and cognitive (jump-to-conclusion) mechanisms. Along the spectrum of thinking, from the mild to the severe, enhanced worrying, salience attribution, overvalued concepts, suspicion/mistrust, paranoid ideations, and crystallized delusions may occur with different contents. In recent years intensive research has been started to reveal the presence of subclinical paranoid thoughts in the general population. Applying various screening methods developed for this purpose (delusions inventories, psychometric tests, virtual reality laboratory) it has been found that suspicious/mistrustful ideations are fairly common in nonclinical samples and some of these are comparable to that seen in patient population. From the larger occurrence of milder forms to the smaller frequency of more severe delusional thoughts the whole hierarchical phenomenon can be described as a 'paranoia pyramid'. Based on this everyday paranoid thinking style lurking in people, it may well be that 'our life is delusional'. Orv. Hetil., 2016, 157(50), 1979-1988.

Abstract
The antidepressive effect of repetitive transcranial magnetic stimulation (rTMS) has been investigated for almost 20 years now. Several studies have been published aiming to identify the exact and reliable parameters leading to the desired therapeutic effect. However, the related literature shows great variability. The current overview aims to provide a comprehensive overview of factors associated with the therapeutic effect of rTMS in major depression. High frequency stimulation of the left dorsolateral prefrontal cortex (DLPFC) for 3-6 weeks leads to mood improvement comparable to the effect of antidepressive medications in 35-40% of patients. Pharmacotherapy resistant patients treated with rTMS reach remission for 3 months on average. Low frequency stimulation of the right DLPFC appears to be similarly effective, though much less investigated so far. In addition to the exact delineation of the stimulation area, treatment outcome is also related to stimulation intensity as well as the number of sessions and impulses. Considering the safety and tolerability aspects of rTMS, it might be a significant therapeutic support for therapy resistant patients. Above this, patients diagnosed with major depression might benefit from the additional positive influence of rTMS improving the effect of antidepressive medication. Based on converging research evidence, the Food and Drug Administration (FDA) agency approved the use of rTMS as a treatment option for therapy resistant major depression in 2008. So far, in Hungary rTMS is primarily considered as a promising tool in research settings only. Hopefully, patients suffering from major depression will increasingly benefit from the positive therapeutic effect of this intervention.

Abstract
In order to decipher the disease etiology, progression and treatment of multifactorial human brain diseases we utilize a host of different experimental models. Recently, patient-derived human dermal fibroblast (HDF) cultures have re-emerged as promising in vitro functional system for examining various cellular, molecular, metabolic and (patho)physiological states and traits of psychiatric disorders. HDF studies serve as a powerful complement to postmortem and animal studies, and often appear to be informative about the altered homeostasis in neural tissue. Studies of HDFs from patients with schizophrenia (SZ), depression, bipolar disorder (BD), autism, attention deficit and hyperactivity disorder and other psychiatric disorders have significantly advanced our understanding of these devastating diseases. These reports unequivocally prove that signal transduction, redox homeostasis, circadian rhythms and gene*environment (G*E) interactions are all amenable for assessment by the HDF model. Furthermore, the reported findings suggest that this underutilized patient biomaterial, combined with modern molecular biology techniques, may have both diagnostic and prognostic value, including prediction of response to therapeutic agents.

Abstract
The investigation of schizophrenia's aetiology and pathomechanism is of high importance in neurosciences. In the recent decades, analyzing event-related potentials have proven to be useful to reveal the neuropsychological dysfunctions in schizophrenia. Even the very early stages of auditory stimulus processing are impaired in this disorder; this might contribute to the experience of auditory hallucinations. The present review summarizes the recent literature on the relationship between auditory hallucinations and event-related potentials. Due to the dysfunction of early auditory sensory processing, patients with schizophrenia are not able to locate the source of stimuli and to allocate their attention appropriately. These deficits might lead to auditory hallucinations and problems with daily functioning. Studies involving high risk groups may provide tools for screening and early interventions; thus improving the prognosis of schizophrenia.

Abstract
Gambling disorder has been listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM) for more than three decades. During this time, its diagnostic set of criteria has gone through significant changes. In the DSM-5, gambling disorder has been moved from Disruptive, Impulse-Control and Conduct Disorders to Substance- Related and Addictive Disorders, which acknowledges and expresses that gambling disorder has similar features compared to substance related disorders. The aim of the present review is to reveal the reasons behind this category replacement, and to examine the similarities between gambling disorder and alcohol dependence from the perspectives of symptomatology, etiology and epidemiology.

Abstract
Association between genetic variants of the reelin (RELN) gene and the risk for developing Alzheimer's disease (AD) was examined in a sample of 432 patients and 308 controls. Single marker and haplotype analyses revealed that the strongly linked rs528528 and rs607755 polymorphisms are associated with AD risk in a gender specific manner. Among men, but not in women the rs528528 T/T and rs607755 A/A genotypes were significantly associated with the susceptibility to AD.

Abstract
Clinical diagnosis of Alzheimer's disease (AD) relying on symptomatic features has a low specificity, emphasizing the importance of the pragmatic use of neurochemical biomarkers. The most advanced and reliable markers are amyloid-β (Aβ42), total tau (t-tau), and phosphorylated tau (p-tau) in cerebrospinal fluid (CSF) with relatively high levels of sensitivity, specificity, and diagnostic accuracy. Recent advances within the field of proteomics offer the potential to search for novel biomarkers in CSF by using modern methods, such as microarrays. The purpose of this study was to identify pathognostic proteins in CSF obtained from patients whose clinical AD diagnosis was confirmed by the "core" biomarkers. CSF samples were obtained from 25 AD patients and 25 control individuals. The levels of Aβ42, t-tau, and p-tau were measured by ELISA. In the microarray experiments, ultrasensitive slides representing of 653 antigens were used. Apolipoprotein E genotyping was also determined. A decrease of seven CSF proteins in AD were found, four of them (POLG, MGMT, parkin, and ApoD) have a protective function against neuronal death, while the remaining three proteins (PAR-4, granzyme B, Cdk5) trigger multiple pathways facilitating neuronal cell death. Since these proteins from CSF samples could not be identified by western blot, their decreased levels in AD patients were not verified. Our results provide new information of pathognostic importance of POLG and granzyme B in AD. Although the function of MGMT, parkin, ApoD, PAR-4, and Cdk5 was previously known in AD, the findings presented here provide novel evidence of the significance of CSF analysis in the mapping of the AD pathomechanism.

Abstract
Preventive measures, prognosis, or selected therapy in multifactorial maladies, including Alzheimer's disease (AD), require the application of a wide range of diagnostic assays. There is a large unmet need for relatively simple, blood-based biomarkers in this regard. We have recently developed a rapid and reliable flow cytometry and antibody-based method for the quantitative measurement of various red blood cell (RBC) membrane proteins from a drop of blood. Here, we document that the RBC expression of certain membrane proteins, especially that of the GLUT1 transporter and the insulin receptor (INSR), is significantly higher in AD patients than in age-matched healthy subjects. The observed differences may reflect long-term metabolic alterations relevant in the development of AD. These findings may pave the way for a diagnostic application of RBC membrane proteins as relatively stable and easily accessible personalized biomarkers in AD.

Abstract
Some of the complexities of surgical interventions include neurological and psychiatric disturbances. Prompt identification and early treatment of these complications are pivotal in achieving excellent clinical results. Recognizing major adverse events such as stroke, seizure or delirium is usually straight-forward, however the discovery of less frequent or more subtle post-operative changes such as cognitive dysfunction might be delayed due to lack of appropriate diagnostic tools. This review summarizes biological markers that can be utilized as surrogates in evaluating surgery-related neuro-psychiatric disorders.

Abstract
BACKGROUND AND AIMS Mental disorders with psychotic features are overlapping in many ways and there are a growing number of comparative studies in the last decades regarding this. Cognitive deficit is well underpinned in schizophrenia, but fewer studies are conducted in this area including patients with bipolar affective disorder. Therefore the aim of the present study was to investigate the cognitive performance of these two patient groups and healthy controls. The Wisconsin Card Sorting Task is a very sensitive measure of the shifting function. Schizophrenic patients perform consistently poorer on this task than healthy controls, while there are not much data about individuals with bipolar affective disorder. METHODS The Wisconsin Card Sorting Task and clinical symptom rating scales were administered to 26 patients with schizophrenia, 24 with bipolar affective disorder and 21 healthy controls. RESULTS Significant differences were found among the performance of the three groups using four different dimensions of the Wisconsin Card Sorting Task. The schizophrenic group made more perseverative errors and achieved less conceptual level responses and completed fewer categories compared to healthy controls. Patients with schizophrenia were able to complete fewer categories and had fewer conceptual level responses than the bipolar group. No significant differences were observed between patients with bipolar disorder and healthy controls. CONCLUSIONS According to these results, patients with schizophrenia and bipolar affective disorder showed no similarities on the Wisconsin Card Sorting Task. Bipolar patients performed the task on the same level as healthy individuals did. The two mental disorders influence cognitive performance differently.

Abstract
Background: The nature of episodic memory deficit in intermediate-term abstinence from alcohol in alcohol dependence (AD) is not yet clarified. Deficits in inhibitory control are commonly reported in substance use disorders. However, much less is known about cognitive control suppressing interference from memory. The Think/No-think (TNT) paradigm is a well established method to investigate inhibition of associative memory retrieval. Methods: Thirty-six unmedicated patients with AD and 36 healthy controls (HCs) performed the TNT task. Thirty image–word pairs were trained up to a predefined accuracy level. Cued recall was examined in three conditions: Think (T) for items instructed to-be-remembered, No-think (NT) assessing the ability to suppress retrieval and Baseline (B) for general relational memory. Premorbid IQ, clinical variables and impulsivity measures were quantified. Results: AD patients had a significantly increased demand for training. Baseline memory abilities and effect of practice on retrieval were not markedly different between the groups. We found a significant main effect of group (HC vs. AD) × condition (B, T, and NT) and a significant difference in mean NT–B scores for the two groups. Discussion: AD and HC groups did not differ essentially in their baseline memory abilities. Also, the instruction to focus on retrieval improved episodic memory performance in both groups. Crucially, control participants were able to suppress relational words in the NT condition supporting the critical effect of cognitive control processes over inhibition of retrieval. In contrast to this, the ability of AD patients to suppress retrieval was found to be impaired.

Abstract
BACKGROUND The Clock Drawing Test (CDT) is a widely-used, rapid assessment tool for the screening of cognitive decline though its evaluation and interpretation are still not uniform. The aim of present study was to investigate the difference in sensitivity and specificity of two types of CDTs and to compare the clinical benefits of quantitative and semiquantitative scoring systems. OBJECTIVE To investigate the difference in sensitivity and specificity of two types of CDTs and to compare the clinical benefits of quantitative and semiquantitative scoring systems. METHODS Six hundred and ninety-two participants with or without dementia completed 10-item CDTs in nursing homes in two counties in southern Hungary. The dementia was not further subclassified. The results of the two tests, CDT1 (representing five minutes to a quarter to four) and CDT2 (representing ten past five), were evaluated quantitatively and semiquantitatively. RESULTS In the quantitative evaluation, the sensitivity and the specificity for the diagnosis of dementia at cut-off scores of 7 points were determined: 87.1% and 51.9%, respectively, for CDT1, and 81.7% and 57% for CDT2, respectively. The semiquantitative analysis revealed a sensitivity of 67.3% and a specificity of 65.3% for CDT1, and of 64.6% and 66.6% for CDT2, respectively. CONCLUSION The results of CDT tests do not appear to depend on the positions of the clock hands and additionally suggest that the quantitative evaluation method is more sensitive than the semiquantitative method.

Abstract
Stress is considered as a major contributor to the development and exacerbation of psoriasis by a significant proportion of patients and dermatologists. As both stressor and its effects are subject-dependent, thus extremely difficult to measure, our understanding of the exact role of stress in disease development was limited for a long time. In the past decade several new studies were carried out which expanded our knowledge on the pathophysiologic processes linking stress to psoriasis via with their objective measurements and the applied new techniques. The authors review the current literature of both psychological (alexithymia, personality, affect) and biological (cortisol, epinephrine, neurogenic inflammation) factors influencing stress perception and response in psoriasis. Results of recent investigations support previous reports about the interaction between stress and psoriasis with objective evidence. Knowing how effective stress-reducing psychopharmacologic and psychotherapeutic interventions are in the treatment of psoriasis the authors hope that this review contributes to a wider acceptance of the psychosomatic attitude in everyday dermatologic practice.

Abstract
Temperament and character factors are strongly related to the developmental, clinical, and treatment aspects of alcohol dependence. This study had the aim of revealing the underlying personality structure and individual differences in the symptoms of alcohol dependence measured by multiple severity indicators. Patients with alcohol dependence exhibited higher levels of novelty seeking and harm avoidance, and lower levels of persistence, self-directedness, and cooperativeness. Especially novelty seeking was connected with more severe alcohol dependence. These characteristics could be useful targets of interventions and Temperament and Character Inventory is therefore a useful measurement to identify patients with more severe alcohol-related problems.

Abstract
Stress is an integral component of life that can sometimes cause a critical overload, depending on the qualitative and quantitative natures of the stressors. The involvement of actin, the predominant component of dendritic integrity, is a plausible candidate factor in stress-induced neuronal cytoskeletal changes. The major aim of this study was to compare the effects of three different stress conditions on the transcription and translation of actin-related cytoskeletal genes in the rat brain. Male Wistar rats were exposed to one or other of the frequently used models of physical stress, i.e. electric foot shock stress (EFSS), forced swimming stress (FSS), or psychosocial stress (PSS) for periods of 3, 7, 14, or 21 days. The relative mRNA and protein expressions of β-actin, cofilin and mitogen-activated protein kinase 1 (MAPK-1) were determined by qRT- PCR and western blotting from hippocampus and frontal cortex samples. Stressor-specific alterations in both β-actin and cofilin expression levels were seen after stress. These alterations were most pronounced in response to EFSS, and exhibited a U-shaped time course. FSS led to a significant β-actin mRNA expression elevation in the hippocampus and the frontal cortex after 3 and 7 days, respectively, without any subsequent change. PSS did not cause any change in β-actin or cofilin mRNA or protein expression in the examined brain regions. EFSS, FSS and PSS had no effect on the expression of MAPK-1 mRNA at any tested time point. These findings indicate a very delicate, stress type-dependent regulation of neuronal cytoskeletal components in the rat hippocampus and frontal cortex.

Abstract
Genetic variants of the serotonergic neurotransmitter system are potential contributing factors in the pathological processes underlying Alzheimer's disease (AD). We examined polymorphisms of the serotonin transporter (SLC6A4) and serotonin receptor 2A (HTR2A) genes for possible association with AD, and therefore genotyped 5-HTTLPR, STin2-VNTR and HTR2A T102C polymorphisms in 252 Hungarian AD patients and 234 ethnically matched control individuals. We did not detect statistically significant differences in genotype distribution comparing the AD and the control group when the polymorphisms were investigated separately. Logistic regression analyses, however, revealed an interaction effect between 5-HTTLPR and HTR2A T102C (p=0.019), but not between 5-HTTLPR and STin2-VNTR (p=0.494) or STin2-VNTR and HTR2A T102C (p=0.310) polymorphisms. Our study suggests no individual influence of the investigated polymorphisms but a potential combined effect of the 5-HTTLPR L/L and HTR2A T102C C/C genotypes on AD risk. However, the results need to be treated with considerable caution, and further analyses in larger samples are required.

Abstract
Stress, depending on its level and quality, may cause adaptive and maladaptive alterations in brain functioning. As one of its multiple effects, elevated blood cortisol levels decrease the synthesis of the neuroprotective BDNF, thus leading to hippocampal atrophy and synapse loss, and rendering it a possible cause for the Alzheimer's disease (AD) related neuropathological and cognitive changes. As a result of the stress response, intraneuronal alterations--also affecting the metabolism of beta-actin--can develop. These have a role in the regulation of memory formation (LTP), but in pathological conditions (AD) they could lead to the accumulation of Hirano bodies (actin-cofilin rods). According to the dementia treatment guidelines, the behavioural and psychological symptoms of AD can be treated with certain antipsychotics. Therefore, the aim of our study was to examine the effects of sertindole (currently not used in the standard management of AD) on the transcription of some AD associated genes (amyloid precursor protein [APP], mitogen activated protein kinase-1 [MAPK-1], beta-actin) in the brain of rats exposed to chronic immobilization stress (CIS). Male Wistar rats were exposed to CIS for three weeks. The four groups were: control (n = 16), CIS (n = 10), 10 mg/kg sertindole (n = 5) and 10 mg/kg sertindole + CIS (n = 4). Following transcardial perfusion, the relative levels of hippocampal and cortical mRNA of the previously mentioned genes were measured with real-time PCR. CIS induced hippocampal beta-actin (p < 0.01), MAPK-1 and APP (p < 0.05) mRNA overexpression. The simultaneous administration of sertindole suppressed this increase in beta-actin, MAPK-1 and APP expression (p < 0.05). Ours is the first report about CIS induced beta-actin gene overexpression. This finding, in accordance with the similar results in APP and MAPK-1 expression, underlines the significance of cytoskeletal alterations in AD pathogenesis. The gene expression reducing effect of sertindole suggests that antipsychotic drugs may have a neuroprotective effect.

Abstract
With the development of DSM-V and ICD-11 the definitions of psychiatric disorders are under re-evaluation. The emphasis is shifted from distinct disorders to clusters defined not only by symptomatology, but also by underlying neurobiology and cognitive deficits. Bipolar disorder I (BD-I) and schizophrenia (SZ) are of special interest since their differential diagnosis is often problematic and they partially overlap in measures ranging from genetics to neurophysiology. Event-related potentials (ERPs) are one of the most studied factors but the results are still controversial, primarily in BD-I, where ERPs reflecting different stages of auditory information processing have been much less investigated. In this study, we aimed at investigating the changes of five auditory event-related potentials (P50 and N100 suppression, duration and pitch deviant mismatch negativity (MMN) and P3b) in 20 SZ and 20 BD-I patients with a history of psychosis and 21 healthy control subjects. Our data revealed substantial differences between the two patient groups. Only patients with SZ demonstrated impaired N100 suppression, shorter duration deviant MMN latency and attenuated P3b amplitude, while prolonged pitch deviant MMN latency was found to be characteristic of the BD-I group. No shared ERP abnormalities were observed among the patient groups. Our results indicate that SZ and BD-I are characterized by highly different neurophysiological profiles when measured in the same laboratory setting.
