REVIEW
Till Faehrmann, Gerald Zernig, Sergei Mechtcheriakov
One of the crucial purposes of treating alcohol-dependent patients is to enhance their ability to stay abstinent after detoxification therapy. Anxiety and stress vulnerability are the main factors provoking alcohol craving and relapse. In the first months of abstinence, alcohol-dependent patients frequently show sleep disturbances, irritability and depression, indicating chronic activation of stress pathways. In addition, the loss of confidence in interpersonal interactions results in social withdrawal and reduced willingness to participate in therapeutic programs...

Humans belong to a minority of mammalian species that exhibit monogamous pair-bonds, thereby enabling biparental care of offspring. The high reward value of interpersonal closeness and touch in couples is a key proximate mechanism facilitating the maintenance of enduring romantic bonds. However, surprisingly, the neurobiological underpinnings mediating the unique experience of a romantic partner's touch remain unknown. In this randomized placebo (PLC)-controlled, between-group, pharmacofunctional magnetic resonance imaging (fMRI) study involving 192 healthy volunteers (96 heterosexual couples), we intranasally administered 24 IU of the hypothalamic peptide oxytocin (OXT) to either the man or the woman...

Dissociative identity disorder (DID) is a chronic post-traumatic disorder where developmentally stressful events in childhood, including abuse, emotional neglect, disturbed attachment, and boundary violations are central and typical etiological factors. Familial, societal, and cultural factors may give rise to the trauma and/or they may influence the expression of DID. Memory and the construction of self-identity are cognitive processes that appear markedly and centrally disrupted in DID and are related to its etiology...

BACKGROUND & OBJECTIVE: Rehabilitation focuses brain-behavior relationship which highlights interaction between psychological and neurobiological factors for better patient care. There is a missing link in the literature about socio-cognitive aspects of frontal lobe epilepsy. Our objective was to examine prefrontal cortical functioning (PCF) and empathic abilities in patients with frontal lobe epilepsy (FLE). Further, we analyzed whether any relationship between components of dispositional empathy and PCF exists in patients with FLE...

Psychopathic traits are a manifestation of a personality pathology that comprises a core affective-interpersonal dysfunction (callous-unemotional traits) and an impulsive-antisocial behavioral component. Of particular importance, psychopathic traits are associated with the perpetration of some of the most severe acts of violence, and they appear to indicate a subset of youth at risk for earlier onset, greater frequency, and persistence of violent offending. Although these youth represent a minority of the population, they commit a significant proportion of the violence in the general community...

PURPOSE OF REVIEW: Non-suicidal self-injury (NSSI) is a common mental health threat among adolescents. This review aims to present the current literature on epidemiology, etiology, and therapeutic approaches with a focus on the period of adolescence. RECENT FINDINGS: NSSI is widespread among adolescents both in community as well as in clinical settings with lifetime prevalence rates between 17 and 60% in recent studies. It is influenced by multiple factors including social contagion, interpersonal stressors, neurobiological background, as well as emotional dysregulation and adverse experiences in childhood...

The very incomprehensibility of the suicidal act has been occupying the minds of researchers and health professionals for a long time. Several theories of suicide have been proposed since the beginning of the past century, and a myriad of neurobiological studies have been conducted over the past two decades in order to elucidate its pathophysiology. Both neurobiology and psychological theories tend to work in parallel lines that need behavioral and empirical data respectively, to confirm their hypotheses. In this review, we are proposing a "Life Span Model of Suicide" with an attempt to integrate the "Stress-Diathesis Model" and the "Interpersonal Model of Suicide" into a neurobiological narrative and support it by providing a thorough compilation of related genetic, epigenetic, and gene expression findings...

BACKGROUND: Psychiatry has faced significant criticism for overreliance on the Diagnostic and Statistical Manual of Mental Disorders (DSM) and medications with purported disregard for empathetic, humanistic interventions. AIMS: To develop an empirically based qualitative theory explaining how psychiatrists use empathy in day-to-day practice, to inform practice and teaching approaches. METHOD: This study used constructivist grounded theory methodology to ask (a) 'How do psychiatrists understand and use empathetic engagement in the day-to-day practice of psychiatry?' and (b) 'How do psychiatrists learn and teach the skills of empathetic engagement?' The authors interviewed 17 academic psychiatrists and 4 residents and developed a theory by iterative coding of the collected data...

The effects of trauma have been the focus of study by several researchers. However, at present, there is no diagnostic criteria that includes all forms of clinical presentations of subjects who have been victims of prolonged trauma or that have started at developmentally vulnerable times in the victim's life. Unlike those individuals who are victims of a single traumatic event, individuals who suffer multiple traumas that occur at vulnerable times, are at risk of developing a complex trauma. The concept of complex trauma was introduced in the last decades and is characterized by a symptomatic pleomorphism: emotional instability, somatization, dissociation; changes in identity, pathological changes in interpersonal relationships and suicidal behavior...

Research has long acknowledged the centrality of parents' subjective experiences in the caregiving role for the organization of parenting behaviors and family functioning. Recent scientific advances in cognitive process models and in the neurobiology of parenting indicate that parenting is shaped in part by conscious and nonconscious cognitive processes. This study extends a growing literature on neurocognitive models of parenting by exploring the extent to which attention processes in parents operate independently and interactively with intrapsychic processes, proximal interpersonal stressors, and the larger socioeconomic context to predict perceptions of parenting hassles in primarily low-income Latino/a parents of young children living in urban areas of concentrated disadvantage (N = 185)...

Major depression is a debilitating condition characterised by diverse neurocognitive and behavioural deficits. Nevertheless, our species-typical capacity for depressed mood implies that it serves an adaptive function. Here we apply an interdisciplinary theory of brain function to explain depressed mood and its clinical manifestations. Combining insights from the free-energy principle (FEP) with evolutionary theorising in psychology, we argue that depression reflects an adaptive response to perceived threats of aversive social outcomes (e...

Parental ADHD symptomatology and related impairments have been robustly associated with youth ADHD across decades of work. Notably, these factors may impede typical development of child self-regulation capabilities through both neurobiological and interpersonal processes. High heritability of estimates for the disorder further suggest that these effects are likely genetically-mediated, at least in part. Variation within the dopamine D4 receptor gene (DRD4) has been shown to moderate parental influences on youth ADHD...

Technological developments in neuroscience over the last 20 years have generated excitement about the potential of neuroscientific insights for the understanding of and intervention in children's and adolescents' behavior. This article introduces some ways in which new results from developmental cognitive neuroscience have been appropriated in the context of adolescent mental health. We also consider social and interpersonal factors that drive the use of neurobiological markers of mental disorders in pediatric psychiatry...

The neuropeptide oxytocin has been shown to affect social interaction. Meanwhile, the underlying mechanism remains highly debated. Using an interpersonal finger-tapping paradigm, we investigated whether oxytocin affects the ability to synchronise with and adapt to the behaviour of others. Dyads received either oxytocin or a non-active placebo, intranasally. We show that in conditions where one dyad-member was tapping to another unresponsive dyad-member - i.e. one was following another who was leading/self-pacing - dyads given oxytocin were more synchronised than dyads given placebo...

We know a great deal about schizophrenia, but the current state of the art is one of uncertainty. Researchers are confused, and patients feel misunderstood. This situation has been identified as due largely to the fact that the dominant neurobiological perspective leaves out the person. The aim of the present article is to review and integrate a series of clinical, phenomenological, historical, cultural, epidemiological, developmental, epigenetic, and therapeutic phenomena in support of a suggestion that schizophrenia is above all a disorder of the person rather than of the brain...

Extraversion-introversion is a personality dimension referring to individual differences in social behavior. In the past, neurobiological research on extraversion was almost entirely based upon questionnaires which inform about the explicit self-concept. Today, indirect measures are available that tap into the implicit self-concept of extraversion which is assumed to result from automatic processing functions. In our study, brain activation while viewing facial expression of affiliation relevant (i.e., happiness, and disgust) and irrelevant (i...

Neurobiological models of self-control predominantly focus on the role of prefrontal brain mechanisms involved in emotion regulation and impulse control. We provide evidence for an entirely different neural mechanism that promotes self-control by overcoming bias for the present self, a mechanism previously thought to be mainly important for interpersonal decision-making. In two separate studies, we show that disruptive transcranial magnetic stimulation (TMS) of the temporo-parietal junction-a brain region involved in overcoming one's self-centered perspective-increases the discounting of delayed and prosocial rewards...
