TL;DR: In this paper, a comprehensive review of the course of schizophrenia by applying stringent methodological and diagnostic study-selection criteria is provided, including positive and negative symptoms, cognition, and findings obtained by neuroimaging.
Abstract: Despite several decades of research, our knowledge of the long-term course of schizophrenia (SZ) is hampered by a lack of homogeneity of both research methods and phenotypic definitions of SZ's course. We provide a comprehensive review of the course of SZ by applying stringent methodological and diagnostic study-selection criteria. We report on positive and negative symptoms, cognition, and findings obtained by neuroimaging. In addition, we perform a meta-analysis of longitudinal studies of cognition in humans. We selected 35 human studies focusing on a narrow SZ phenotype, employing a follow-up duration of six months or more and consistent methodology at the different measurement points. For the meta-analysis on global cognitive change, eight and four studies were used to compare SZ to healthy and psychiatric controls, respectively. We find that the course of SZ is characterized by a constancy or even improvement of positive and negative symptoms and by fairly stable cognitive impairment, reflecting structural frontal and temporal cortical pathology. Progressive changes of the frontal cortex appear to develop in parallel with changes in symptomatology and executive impairment. Despite stable differences in cognition between patients and controls over the time intervals studied, high heterogeneity in the magnitude of effect sizes is present, and age is identified as one of its potential sources. Meta-regression shows these magnitudes to depend on the age at study inclusion. For future research, a combination of longitudinal and cross-sectional research designs is warranted to better account for potential cohort effects.

TL;DR: Four major evidence-based treatments for borderline personality disorder—dialectical behavioral therapy, mentalization-based treatment, transference-focused psychotherapy, and General Psychiatric Management—and possible modes of implementation in adherent and integrative forms are evaluated.
Abstract: Learning objective After participating in this activity, learners should be better able to:• Evaluate evidence-based therapies for borderline personality disorder Abstract Several manualized psychotherapies for treating borderline personality disorder (BPD) have been validated in randomized, controlled trials. Most of these approaches are highly specialized, offering different formulation of BPD and different mechanisms by which recovery is made possible. Mental health clinicians are challenged by the degree of specialization and clinical resources that these approaches require in their empirically validated adherent forms. While these effective treatments have renewed optimism for the treatment of BPD, clinicians may feel limited in their ability to offer any of them or may integrate an eclectic assortment of features from the different treatments. This article will evaluate four major evidence-based treatments for BPD-dialectical behavioral therapy, mentalization-based treatment, transference-focused psychotherapy, and General Psychiatric Management-and possible modes of implementation in adherent and integrative forms. Models of implementing these diverse treatment approaches will be evaluated, and the potential advantages of combining evidence-based treatments will be discussed, along with some cautionary notes. A proposal for providing stepwise care through assessment of clinical severity will be presented as a means of achieving system-wide changes and greater access to care.

TL;DR: Empirically derived knowledge about DID has replaced outdated myths and vigorous dissemination of the knowledge base is warranted, because the cost of ignorance about DID is high not only for individual patients but for the whole support system in which they reside.
Abstract: Dissociative identity disorder (DID) is a complex, posttraumatic, developmental disorder for which we now, after four decades of research, have an authoritative research base, but a number of misconceptualizations and myths about the disorder remain, compromising both patient care and research. This article examines the empirical literature pertaining to recurrently expressed beliefs regarding DID: (1) belief that DID is a fad, (2) belief that DID is primarily diagnosed in North America by DID experts who overdiagnose the disorder, (3) belief that DID is rare, (4) belief that DID is an iatrogenic, rather than trauma-based, disorder, (5) belief that DID is the same entity as borderline personality disorder, and (6) belief that DID treatment is harmful to patients. The absence of research to substantiate these beliefs, as well as the existence of a body of research that refutes them, confirms their mythical status. Clinicians who accept these myths as facts are unlikely to carefully assess for dissociation. Accurate diagnoses are critical for appropriate treatment planning. If DID is not targeted in treatment, it does not appear to resolve. The myths we have highlighted may also impede research about DID. The cost of ignorance about DID is high not only for individual patients but for the whole support system in which they reside. Empirically derived knowledge about DID has replaced outdated myths. Vigorous dissemination of the knowledge base about this complex disorder is warranted.

TL;DR: The role of the amygdala in BPD is expanded to consider its functions in coordinating the brain’s dynamic evaluation of the relevance of emotional stimuli in the context of an individual's goals and motivations, and an integrative model that attempts to incorporate the heterogeneous findings is provided.
Abstract: Borderline personality disorder (BPD) is a severe mental disorder with a multifactorial etiology. The development and maintenance of BPD is sustained by diverse neurobiological factors that contribute to the disorder's complex clinical phenotype. These factors may be identified using a range of techniques to probe alterations in brain systems that underlie BPD. We systematically searched the scientific literature for empirical studies on the neurobiology of BPD, identifying 146 articles in three broad research areas: neuroendocrinology and biological specimens; structural neuroimaging; and functional neuroimaging. We consolidate the results of these studies and provide an integrative model that attempts to incorporate the heterogeneous findings. The model specifies interactions among endogenous stress hormones, neurometabolism, and brain structures and circuits involved in emotion and cognition. The role of the amygdala in BPD is expanded to consider its functions in coordinating the brain's dynamic evaluation of the relevance of emotional stimuli in the context of an individual's goals and motivations. Future directions for neurobiological research on BPD are discussed, including implications for the Research Domain Criteria framework, accelerating genetics research by incorporating endophenotypes and gene × environment interactions, and exploring novel applications of neuroscience findings to treatment research.

TL;DR: A systematic review of 46 separate papers presenting the results of 18 longitudinal studies that have followed children who are at familial high risk of developing psychotic disorders suggests that offspring of parents with schizophrenia are at high risk for poor developmental and general mental health outcomes.
Abstract: A significant body of longitudinal research has followed the offspring of parents with schizophrenia. This article presents a systematic review of 46 separate papers presenting the results of 18 longitudinal studies that have followed children who are at familial high risk of developing psychotic disorders. The studies suggest that these children do show distinct developmental patterns characterized by higher rates of obstetric complication, neurodevelopmental features such as motor and cognitive deficits, and distinctive social behavior. This review summarizes those findings according to child developmental stages. Twelve of the studies followed offspring into adulthood and examined psychiatric diagnoses. From 15% to 40% of children at familial high risk developed psychotic disorders in adulthood. Many also received other psychiatric diagnoses such as mood or anxiety disorders. This combination of results suggests that offspring of parents with schizophrenia are at high risk not just for schizophrenia but, more broadly, for poor developmental and general mental health outcomes. The clinical implications of the findings are discussed, as are new prognostic strategies and potential programs for selective prevention.

TL;DR: This article aims to integrate early intervention for BPD and mood disorders in the clinical context of developmental and phenomenological change and evolution, and acknowledges that the early stages of these disorders cannot be disentangled sufficiently to allow for disorder-specific preventive measures and early interventions.
Abstract: Borderline personality disorder (BPD) has been demonstrated to be a reliable and valid construct in young people (adolescents and young adults). Both borderline- and mood-related psychopathology become clinically apparent from puberty through to young adulthood, frequently co-occur, can reinforce one another, and can be difficult to differentiate clinically. This Gordian knot of overlapping clinical features, common risk factors, and precursors to both BPD and mood disorders complicates clinical assessment, prevention, and treatment. Regardless of whether an individual crosses an arbitrary diagnostic threshold, a considerable proportion of young people with borderline- and mood-related psychopathology will develop significant and persistent functional, vocational, and interpersonal impairment and disability during this critical risk and developmental period. There is a clear need for early intervention, but spurious diagnostic certainty risks stigma, misapplication of diagnostic labels, inappropriate treatment, and unfavorable outcomes. This article aims to integrate early intervention for BPD and mood disorders in the clinical context of developmental and phenomenological change and evolution. "Clinical staging," similar to disease staging in general medicine, is presented as a pragmatic, heuristic, and trans-diagnostic framework to guide prevention and intervention. It acknowledges that the early stages of these disorders cannot be disentangled sufficiently to allow for disorder-specific preventive measures and early interventions. Clinical staging defines an individual's location along the continuum of the evolving temporal course of a disorder. Such staging aids differentiation of early or milder clinical phenomena from those that accompany illness progression and chronicity, and suggests the application of appropriate and proportionate intervention strategies.

TL;DR: A focus on interrelated networks and brain-activity changes between rest and task states provides a neural-system perspective for future research on cognitive vulnerability and resilience, and may potentially guide the development of new intervention strategies for MDD.
Abstract: Although it is generally accepted that cognitive factors contribute to the pathogenesis of major depressive disorder (MDD), there are missing links between behavioral and biological models of depression. Nevertheless, research employing neuroimaging technologies has elucidated some of the neurobiological mechanisms related to cognitive-vulnerability factors, especially from a whole-brain, dynamic perspective. In this review, we integrate well-established cognitive-vulnerability factors for MDD and corresponding neural mechanisms in intrinsic networks using a dual-process framework. We propose that the dynamic alteration and imbalance among the intrinsic networks, both in the resting-state and the rest-task transition stages, contribute to the development of cognitive vulnerability and MDD. Specifically, we propose that abnormally increased resting-state default mode network (DMN) activity and connectivity (mainly in anterior DMN regions) contribute to the development of cognitive vulnerability. Furthermore, when subjects confront negative stimuli in the period of rest-to-task transition, the following three kinds of aberrant network interactions have been identified as facilitators of vulnerability and dysphoric mood, each through a different cognitive mechanism: DMN dominance over the central executive network (CEN), an impaired salience network-mediated switching between the DMN and CEN, and ineffective CEN modulation of the DMN. This focus on interrelated networks and brain-activity changes between rest and task states provides a neural-system perspective for future research on cognitive vulnerability and resilience, and may potentially guide the development of new intervention strategies for MDD.

TL;DR: An updated review of the literature on the association between autism spectrum disorder and violence from 1943 to 2014 found specific generative and associational risk factors may increase violence risk among individuals with ASD.
Abstract: INTRODUCTION: For the past two decades, researchers have been using various approaches to investigate the relationship, if any, between autism spectrum disorder (ASD) and violence. The need to clarify that relationship was reinforced by the tragic mass shooting at Sandy Hook Elementary School in Newtown, Connecticut, in December 2012 by an individual diagnosed with Asperger's syndrome. The purpose of this article is (1) to provide an updated review of the literature on the association between ASD and violence, and (2) to examine implications for treating, and for preventing violence by, individuals with ASD. METHOD: A review of all published literature regarding ASD and violence from 1943 to 2014 was conducted using electronic and paper searches. RESULTS: Although some case reports have suggested an increased violence risk in individuals with ASD compared to the general population, prevalence studies have provided no conclusive evidence to support this suggestion. Among individuals with ASD, however, generative (e.g., comorbid psychopathology, social-cognition deficits, emotion-regulation problems) and associational (e.g., younger age, Asperger's syndrome diagnosis, repetitive behavior) risk factors have been identified or proposed for violent behavior. CONCLUSIONS: While no conclusive evidence indicates that individuals with ASD are more violent than those without ASD, specific generative and associational risk factors may increase violence risk among individuals with ASD. Further research would help to clarify or confirm these findings, suggest potential directions for evaluation, treatment, and prevention, and potentially provide compelling empirical support for forensic testimony regarding defendants with ASD charged with violent crimes.

TL;DR: A redefined model of mind-body interaction in anxiety and somatic symptoms is presented and appraised in the context of joint hypermobility syndrome, a constitutional variant associated with autonomic abnormalities and vulnerability to anxiety disorders.
Abstract: Anxiety and somatic symptoms have a high prevalence in the general population. A mechanistic understanding of how different factors contribute to the development and maintenance of these symptoms, which are highly associated with anxiety disorders, is crucial to optimize treatments. In this article, we review recent literature on this topic and present a redefined model of mind-body interaction in anxiety and somatic symptoms, with an emphasis on both bottom-up and top-down processes. Consideration is given to the role played in this interaction by predisposing physiological and psychological traits (e.g., interoception, anxiety sensitivity, and trait anxiety) and to the levels at which mindfulness approaches may exert a therapeutic benefit. The proposed model of mind-body interaction in anxiety and somatic symptoms is appraised in the context of joint hypermobility syndrome, a constitutional variant associated with autonomic abnormalities and vulnerability to anxiety disorders.

TL;DR: Major findings and emerging directions in prodromal research are summarized and recommendations are provided for clinicians working with individuals suspected to be at high risk for psychosis and for testing early-intervention strategies.
Abstract: Learning objectives After participating in this activity, learners should be better able to: Abstract The psychosis prodrome, or period of clinical and functional decline leading up to acute psychosis, offers a unique opportunity for identifying mechanisms of psychosis onset and for testing early-intervention strategies. We summarize major findings and emerging directions in prodromal research and provide recommendations for clinicians working with individuals suspected to be at high risk for psychosis. The past two decades of research have led to three major advances. First, tools and criteria have been developed that can reliably identify imminent risk for a psychotic disorder. Second, longitudinal clinical and psychobiological data from large multisite studies are strengthening individual risk assessment and offering insights into potential mechanisms of illness onset. Third, psychosocial and pharmacological interventions are demonstrating promise for delaying or preventing the onset of psychosis in help-seeking, high-risk individuals. The dynamic psychobiological processes implicated in both risk and onset of psychosis, including altered gene expression, cognitive dysfunction, inflammation, gray and white matter brain changes, and vulnerability-stress interactions suggest a wide range of potential treatment targets and strategies. The expansion of resources devoted to early intervention and prodromal research worldwide raises hope for investigating them. Future directions include identifying psychosis-specific risk and resilience factors in children, adolescents, and non-help-seeking community samples, improving study designs to test hypothesized mechanisms of change, and intervening with strategies that, in order to improve functional outcomes, better engage youth, address their environmental contexts, and focus on evidence-based neurodevelopmental targets. Prospective research on putatively prodromal samples has the potential to substantially reshape our understanding of mental illness and our efforts to combat it.

TL;DR: Widespread loss of cortical synaptic connectivity appears to be the primary pathology in schizophrenia that is driven by multiple risk genes that adversely affect synaptogenesis and synapse maintenance, as hypothesized by Seymour Kety.
Abstract: Nearly 60 years ago Seymour Kety proposed that research on genetics and brain pathology, but not on neurochemistry, would ultimately lead to an understanding of the pathophysiology of schizophrenia. This article will demonstrate the prescience of Kety's proposal; advances in our knowledge of brain structure and genetics have shaped our current understanding of the pathophysiology of schizophrenia. Brain-imaging techniques have shown that schizophrenia is associated with cortical atrophy and ventricular enlargement, which progresses for at least a decade after the onset of psychotic symptoms. Cortical atrophy correlates with negative symptoms and cognitive impairment, but not with psychotic symptoms, in schizophrenia. Studies with the Golgi-staining technique that illuminates the entire neuron indicate that cortical atrophy is due to reduced synaptic connectivity on the pyramidal neurons and not due to actual loss of neurons. Results of recent genetic studies indicate that several risk genes for schizophrenia are within two degrees of separation from the N-methy-D-aspartate receptor (NMDAR), a subtype of glutamate receptor that is critical to synapse formation and synaptic plasticity. Inactivation of one of these risk genes that encodes serine racemase, which synthesizes D-serine, an NMDAR co-agonist, reproduces the synaptic pathology of schizophrenia. Thus, widespread loss of cortical synaptic connectivity appears to be the primary pathology in schizophrenia that is driven by multiple risk genes that adversely affect synaptogenesis and synapse maintenance, as hypothesized by Kety.
TL;DR: Oxytocin is potentially useful in improving parental behaviors of mothers with PND, but more research is needed to establish its safety because of the uncertain impact of OT on maternal mood.
Abstract: Objective To carry out a systematic review exploring the interconnections between oxytocin, postnatal depression (PND), and parenting. Questions include: (1) How does PND affect parenting? (2) How does oxytocin affect parenting? (3) How does oxytocin affect PND? Methodology To review English articles in major medical databases. Results Compared to nondepressed controls, mothers with PND interact with their infants less sensitively, report feeling less competent, and less often choose recommended practical-parenting strategies. Psychological interventions for mothers with PND generally have positive effects on mother-infant interactions. The administration of oxytocin in community samples tends to improve parental behaviors. Findings exploring the association between oxytocin and PND were inconsistent, with some evidence that oxytocin has a negative impact on mood. Conclusions Oxytocin is potentially useful in improving parental behaviors of mothers with PND, but more research is needed to establish its safety because of the uncertain impact of OT on maternal mood.
TL;DR: It is concluded that refining the measurement of electrophysiological endophenotypes, expanding genetic association studies, and integrating data sets are important next steps for understanding the mechanisms that connect identified genetic risk loci for schizophrenia to the disease phenotype.
Abstract: Endophenotypes are quantitative, heritable traits that may help to elucidate the pathophysiologic mechanisms underlying complex disease syndromes, such as schizophrenia. They can be assessed at numerous levels of analysis; here, we review electrophysiological endophenotypes that have shown promise in helping us understand schizophrenia from a more mechanistic point of view. For each endophenotype, we describe typical experimental procedures, reliability, heritability, and reported gene and neurobiological associations. We discuss recent findings regarding the genetic architecture of specific electrophysiological endophenotypes, as well as converging evidence from EEG studies implicating disrupted balance of glutamatergic signaling and GABAergic inhibition in the pathophysiology of schizophrenia. We conclude that refining the measurement of electrophysiological endophenotypes, expanding genetic association studies, and integrating data sets are important next steps for understanding the mechanisms that connect identified genetic risk loci for schizophrenia to the disease phenotype.
TL;DR: An approach based on Good Psychiatric Management that can reduce negative reactions by ED staff and make ED visits more effective and less harmful is presented.
Abstract: Patients with borderline personality disorder (BPD) are high utilizers of psychiatric emergency services and present unique challenges in that setting. Frequently advised to visit an emergency department (ED) if safety is in question, their experiences once there often do not have beneficial effects. Issues specific to patients with BPD in the ED include volatile interactions with staff, repeat visits, concerns about safety (and liability), and disposition. Emergency department staff attitudes toward these patients are frequently negative when compared to patients with other diagnoses, and can detrimentally affect outcomes and perpetuate stigma regarding BPD. These attitudes are often due to lack of education and training about how to understand, approach, and treat the patient with BPD. The limited literature regarding the treatment of BPD in the ED offers few guidelines. This article presents an approach based on Good Psychiatric Management that can reduce negative reactions by ED staff and make ED visits more effective and less harmful. Relevant principles include psychoeducation, the reinforcement of the connection between symptoms and interpersonal stressors, and employment of an active, authentic therapeutic stance. Training ED staff in these principles could lead to attitudinal changes, reduced stigma, and potentially improved outcomes.
TL;DR: Results of this systematic review and meta-analysis suggest that PTSD may lead to an increase in BMI and, as such, to the development of overweight/obesity, particularly in women.
Abstract: Previous reports have suggested a high prevalence of overweight and obesity among individuals with posttraumatic stress disorder (PTSD). Few studies, however, systematically analyze the relationship between PTSD and body mass index (BMI). We conducted a systematic review and meta-analysis aimed at estimating the association between PTSD and BMI. Fifty-four articles were reviewed, 30 of which (with 191,948 individuals with PTSD and 418,690 trauma-exposed individuals or healthy controls) were eligible for inclusion in the meta-analysis. The pooled standard mean difference, based on a random-effects model, was 0.41 (95% confidence interval, 0.28-0.54; z = 6.26; p < .001). Statistical heterogeneity between the included studies was high (p < .001; I = 99%). Despite limitations, the findings of this systematic review and meta-analysis suggest an association between PTSD and BMI. Furthermore, longitudinal studies tentatively indicate that PTSD may lead to an increase in BMI and, as such, to the development of overweight/obesity, particularly in women. Further prospective studies and research elaborating the nature and etiology of the association are required.
TL;DR: It was apparent that well-designed, standardized research studies on the topic are scarce, and there is consequently limited evidence to guide prevention and intervention strategies for suicidality in this population.
Abstract: BACKGROUND: Suicidality in people with intellectual disability has not been extensively researched. AIM: To identify the nature of the research that has actually been conducted on this topic. METHOD: A search of research databases was conducted according to predefined criteria. Key information was extracted and rated for methodological merit. RESULTS: Twenty-four studies met the inclusion criteria for this systematic review. The aspects of suicidality investigated, which varied among studies, included suicidal attempts, behavior, ideation, and completed suicide. Thirteen studies highlighted risk factors for suicidality in this population. The most frequently noted risk factors were a concurrent mental health difficulty and the level of intellectual disability. Eight studies referred to people with intellectual disabilities' understanding of the concept of death or suicide. Various methodological issues were identified in the studies included. CONCLUSIONS: In what we believe to be first systematic review of suicidality in people with intellectual disabilities, it was apparent that well-designed, standardized research studies on the topic are scarce. There is consequently limited evidence to guide prevention and intervention strategies for suicidality in this population. Language: en
TL;DR: The anterior cingulate cortex, amygdala, and anterior insula emerged as potential markers in major depressive disorder and some anxiety disorders and are still far from being able to use these markers clinically.
Abstract: INTRODUCTION Predictive neuroimaging markers of treatment response are increasingly sought in order to inform the treatment of major depressive and anxiety disorders. We review the existing literature regarding candidate predictive neuroimaging markers of psychotherapy response and assess their potential clinical utility. METHODS We searched Embase, PsycINFO, and PubMed up to October 2014 for studies correlating pretreatment neuroimaging parameters with psychotherapy response in major depressive and anxiety disorders. Our search yielded 40 eligible studies. RESULTS The anterior cingulate cortex, amygdala, and anterior insula emerged as potential markers in major depressive disorder and some anxiety disorders. Results across studies displayed a large degree of variability, however, and to date the findings have not been systematically validated in independent clinical cohorts and have not been shown capable of distinguishing between medication and psychotherapy responders. Also limited is the examination of how neuroimaging compares or might add to other prognostic clinical variables. CONCLUSION While the extant data suggest avenues of further investigation, we are still far from being able to use these markers clinically. Future studies need to focus on longitudinal testing of potential markers, determining their prescriptive value and examining how they might be integrated with clinical factors.
TL;DR: It has been reported that the hyperthymic and the depressive temperaments are related to the more "classic" bipolar disorder, whereas cyclothymic, anxious, and irritable temperamentsare related to more complex manifestations and might predict poor response to treatment, violent or suicidal behavior, and high comorbidity.
Abstract: Bipolar disorder constitutes a challenge for clinicians in everyday clinical practice. Our knowledge concerning this clinical entity is incomplete, and contemporary classification systems are unable to reflect the complexity of this disorder. The concept of temperament, which was first described in antiquity, provides a helpful framework for synthesizing our knowledge on how the human body works and what determines human behavior. Although the concept of temperament originally included philosophical and sociocultural approaches, the biomedical model is dominant today. It is possible that specific temperaments might constitute vulnerability factors, determine the clinical picture, or modify the course of illness. Temperaments might even act as a bridge between genes and clinical manifestations, thus giving rise to the concept of the bipolar spectrum, with major implications for mental health research and treatment. More specifically, it has been reported that the hyperthymic and the depressive temperaments are related to the more "classic" bipolar disorder, whereas cyclothymic, anxious, and irritable temperaments are related to more complex manifestations and might predict poor response to treatment, violent or suicidal behavior, and high comorbidity. Incorporating of the concept of temperament and the bipolar spectrum into the standard training of psychiatric residents might well result in an improvement of everyday clinical practice.
TL;DR: A qualitative literature review on screening for postpartum depression (PPD), as applicable to the general psychiatrist, and the Edinburgh Postnatal Depression Scale is the most widely used screening tool.
Abstract: Learning objectives After participating in this activity, learners should be better able to:• Evaluate the rationale for screening women for postpartum depression• Assess tools for screening for postpartum depression Objective To perform a qualitative literature review on screening for postpartum depression (PPD), as applicable to the general psychiatrist. Results are classified by instrument, timing, and clinical setting of the screen. Data sources A literature search was conducted using the PubMed database for English-language articles published since January 1987. Of the 2406 citations initially identified, 61 articles remained after application of inclusion and exclusion criteria. Results Among numerous screening tools for PPD, the Edinburgh Postnatal Depression Scale is the most widely used. Data suggest that screening for PPD should commence soon after delivery, with subsequent screens at multiple time-points in the postpartum period. Primary care, pediatric, and obstetric settings are all viable locations for screening, but are ineffective without follow-up mental health evaluations. Less data are available to define optimal patterns either for screening in psychiatric settings or for the psychiatrist's role in managing perinatal depression. Conclusions The American Congress of Obstetricians and Gynecologists, American Academy of Pediatrics, and most authors firmly recommend screening for PPD. The Edinburgh Postnatal Depression Scale can be administered in various clinical settings. Screening should occur at multiple time-points throughout the first postpartum year. The psychiatrist's role in early detection and prevention of PPD requires further exploration.
TL;DR: This review discusses recommendations to aid rapid decision making, both diagnostic and therapeutic, and disorders associated with pediatric catatonia, including developmental, acquired, idiopathic, and iatrogenic etiologies, as well as available treatments, and medicolegal considerations.
Abstract: Learning objectives After participating in this activity, learners should be better able to:• Assess the etiologies associated with catatonia in children and adolescents• Evaluate the differential diagnosis of pediatric catatonia• Interpret the literature regarding the treatment of children and adolescents with catatonia OBJECTIVE: Pediatric catatonia is associated with many medical and psychiatric conditions. Mortality is high, and proper treatment can be lifesaving. Catatonia is increasingly recognized in pediatric populations, in which about 20% of cases are related to underlying medical conditions. To minimize morbidity, clinicians must rule out underlying disorders while simultaneously managing symptoms and causes. In our review we discuss (1) recommendations to aid rapid decision making, both diagnostic and therapeutic, (2) emergent conditions and management, (3) disorders associated with pediatric catatonia, including developmental, acquired, idiopathic, and iatrogenic etiologies, (4) available treatments, and (5) medicolegal considerations. Methods Initial PubMed search without date constraints using MeSH terms related to pediatric catatonia, with subsequent searches on pertinent subtopics using PubMed and Google Scholar. Results Pediatric catatonia is a dangerous but treatable neuropsychiatric condition. Psychiatrists need to be aware of differential diagnoses and to be able determine appropriate treatment within a short time frame. With prompt diagnosis and treatment, outcomes can be optimized. Conclusion Pediatric catatonia is underdiagnosed and requires rapid evaluation and management.
TL;DR: Behavioral, neuroimaging, and electrophysiological data are considered to investigate the speech, identity, and affective dimensions of voice processing in schizophrenia, and how abnormalities in these processes might help to elucidate the mechanisms underlying specific phenomenological features of AVH are discussed.
Abstract: Auditory verbal hallucinations (AVH) are a core symptom of schizophrenia. Like "real" voices, AVH carry a rich amount of linguistic and paralinguistic cues that convey not only speech, but also affect and identity, information. Disturbed processing of voice identity, affective, and speech information has been reported in patients with schizophrenia. More recent evidence has suggested a link between voice-processing abnormalities and specific clinical symptoms of schizophrenia, especially AVH. It is still not well understood, however, to what extent these dimensions are impaired and how abnormalities in these processes might contribute to AVH. In this review, we consider behavioral, neuroimaging, and electrophysiological data to investigate the speech, identity, and affective dimensions of voice processing in schizophrenia, and we discuss how abnormalities in these processes might help to elucidate the mechanisms underlying specific phenomenological features of AVH. Schizophrenia patients exhibit behavioral and neural disturbances in the three dimensions of voice processing. Evidence suggesting a role of dysfunctional voice processing in AVH seems to be stronger for the identity and speech dimensions than for the affective domain.
TL;DR: The evidence for implementing cognitive remediation in patients with recent-onset psychosis and people identified as being at high risk for developing schizophrenia is reviewed, and also the evidence for Cognitive remediation to modify neural targets is reviewed.
Abstract: The development of cognitive remediation programs has been a key step toward the creation of a treatment approach to address the cognitive-symptom domain in psychosis. Studies support the efficacy of cognitive remediation in producing moderate effects on cognition at the group level in patients with schizophrenia. Cognitive remediation may harness neuroplasticity in relevant systems that underpin the cognitive functions being addressed. Since neuroplasticity may be greater in people who (1) are younger and (2) have not yet experienced the consequences of long-term psychosis, cognitive remediation may be particularly effective in people in the early course of illness or in the prodrome, prior to the onset of frank symptoms. The present article reviews the evidence for implementing cognitive remediation in patients with recent-onset psychosis and people identified as being at high risk for developing schizophrenia, and also the evidence for cognitive remediation to modify neural targets. Promising findings suggest that cognitive remediation may be useful in addressing cognitive deficits in early-course and prodromal participants. Additionally, a growing literature using neuroimaging techniques demonstrates the ability of cognitive remediation paradigms to engage neural targets.
TL;DR: The basic neurobiology of feeding and hyperactivity seen in both ABA and AN are described, and the research on the role that stress-response and reward pathways play in modulating the homeostatic drive to eat and to expend energy are compiles.
Abstract: Anorexia nervosa (AN) is a psychiatric illness with minimal effective treatments and a very high rate of mortality. Understanding the neurobiological underpinnings of the disease is imperative for improving outcomes and can be aided by the study of animal models. The activity-based anorexia rodent model (ABA) is the current best parallel for the study of AN. This review describes the basic neurobiology of feeding and hyperactivity seen in both ABA and AN, and compiles the research on the role that stress-response and reward pathways play in modulating the homeostatic drive to eat and to expend energy, which become dysfunctional in ABA and AN.
TL;DR: This revision of the GAD algorithm responds to issues raised by new treatments under development (such as pregabalin) and organizes the evidence systematically for practical clinical application.
Abstract: This revision of previous algorithms for the pharmacotherapy of generalized anxiety disorder was developed by the Psychopharmacology Algorithm Project at the Harvard South Shore Program. Algorithms from 1999 and 2010 and associated references were reevaluated. Newer studies and reviews published from 2008-14 were obtained from PubMed and analyzed with a focus on their potential to justify changes in the recommendations. Exceptions to the main algorithm for special patient populations, such as women of childbearing potential, pregnant women, the elderly, and those with common medical and psychiatric comorbidities, were considered. Selective serotonin reuptake inhibitors (SSRIs) are still the basic first-line medication. Early alternatives include duloxetine, buspirone, hydroxyzine, pregabalin, or bupropion, in that order. If response is inadequate, then the second recommendation is to try a different SSRI. Additional alternatives now include benzodiazepines, venlafaxine, kava, and agomelatine. If the response to the second SSRI is unsatisfactory, then the recommendation is to try a serotonin-norepinephrine reuptake inhibitor (SNRI). Other alternatives to SSRIs and SNRIs for treatment-resistant or treatment-intolerant patients include tricyclic antidepressants, second-generation antipsychotics, and valproate. This revision of the GAD algorithm responds to issues raised by new treatments under development (such as pregabalin) and organizes the evidence systematically for practical clinical application.
TL;DR: A comprehensive review of insight in different psychiatric and neurological disorders, with a special focus on brain areas and neurotransmitters that serve as the substrate for this complex phenomenon.
Abstract: In spite of the increasing number of studies on insight in psychiatry and also in neurology and psychology, its nature is still elusive. It encompasses at least three fundamental characteristics: the awareness of suffering from an illness, an understanding of the cause and source of this suffering, and an acknowledgment of the need for treatment. As such, insight is fundamental for patients' management, prognosis, and treatment. Not surprisingly, the majority of available data, which have been gathered on schizophrenia, show a relationship between low insight and poorer outcomes. For mood disorders, however, insight is associated with less positive results. For other psychiatric disorders, insight has rarely been investigated. In neurology, the impaired ability to recognize the presence of sensory, perceptual, motor, affective, or cognitive functioning-referred to as anosognosia-has been related to damage of specific brain regions. This article provides a comprehensive review of insight in different psychiatric and neurological disorders, with a special focus on brain areas and neurotransmitters that serve as the substrate for this complex phenomenon.
TL;DR: A plan is proposed for giving residents adequate training via a generalist model, highlighting minimal didactic and clinical-training objectives and a model curriculum developed at the Massachusetts General Hospital/McLean Hospital residency program.
Abstract: While the public health burden posed by borderline personality disorder (BPD) rivals that associated with other major mental illnesses, the prevailing disposition of psychiatrists toward the disorder remains characterized by misinformation, stigma, aversive attitudes, and insufficient familiarity with effective generalist treatments that can be delivered in nonspecialized health care settings. Residency training programs are well positioned to better equip the next generation of psychiatrists to address these issues, but no consensus or guidelines currently exist for what and how residents should be taught about managing BPD. Instead, disproportionately limited curricular time, teaching of non-evidence-based approaches, and modeling of conceptually confused combinations of techniques drawn from specialty BPD treatments are offered. In this article, we (1) explain why training in a generalist model is sensible and why alternative approaches are not appropriate for residents, (2) propose a plan for giving residents adequate training via a generalist model, highlighting minimal didactic and clinical-training objectives (dubbed "core competencies" and "milestones") and a model curriculum developed at the Massachusetts General Hospital/McLean Hospital residency program, and (3) describe obstacles to implementation of effective generalist training posed by infrastructural, faculty-centered, and resident-centered variables.
TL;DR: A 24-year-old, single, black woman with a past medical history of dysfunctional uterine bleeding and no previous psychiatric history, who was sent to the emergency department by her coworkers for evaluation of acute memory loss and psychological distress, exhibits a labile mood and was initially guarded and somewhat paranoid.
Abstract: Presentation in Emergency Room (Days 1–2) Ms. B is a 24-year-old, single, black woman with a past medical history of dysfunctional uterine bleeding and no previous psychiatric history, who was sent to the emergency department by her coworkers for evaluation of acute memory loss and psychological distress. Her coworkers were concerned about her abnormal behavior, such as arriving to work distressed and tearful, and repeatedly stating that she did not remember how she got there. The previous day she had a similar presentation and was taken to another hospital’s emergency department, where a noncontrast head CT scan revealed no significant findings; she was discharged for outpatient workup. Until that point, she was reported to have been a productive and conscientious worker, and her current presentation was felt to be unprecedented and atypical. On psychiatric interview, she repeatedly asked why she was in the hospital, often within one minute of asking previously. She exhibited a labile mood and was initially guarded and somewhat paranoid. Over a period of several minutes however, she becamemore relaxed andwas able to communicate more successfully. She attributed her presentation to “anxiety” and explained that she had been too busy to be able to seek appropriate mental health treatment. She was unable to detail acute stressors beyond financial matters. She remarked she had persistent anxiety for the past five years, which had slowly progressed to the point of preventing her from driving or from leaving her apartment (except when necessary, as for work). She noted that prior to this time she had been quite social, exemplified by going dancing, singing, and traveling. She also endorsed depression for
TL;DR: It is concluded that adjunctive treatments targeting glutamatergic modulation, as well as supplementation with certain vitamins, have the strongest evidence for use in the treatment of schizophrenia.
Abstract: In this column we examine the recent literature regarding adjunctive antipsychotic treatment of schizophrenia. We provide a brief introduction outlining the urgent need for new therapeutics, particularly for the treatment of negative and cognitive symptoms of schizophrenia. We then address (by mechanism of action) the most extensively studied adjunctive antipsychotic treatments. We conclude that adjunctive treatments targeting glutamatergic modulation, as well as supplementation with certain vitamins, have the strongest evidence for use in the treatment of schizophrenia. Further, larger randomized, controlled trials are needed, focusing on certain subgroups of patients and specific antipsychotic medications.
TL;DR: A clinical vignette of malignant catatonia that required court-ordered ECT is presented, followed by a discussion of practical and legal obstacles to expediting emergent ECT when patients cannot provide consent.
Abstract: In cases of malignant catatonia, prompt administration of electroconvulsive therapy (ECT) can decrease mortality, whereas delays to initiating ECT have resulted in adverse outcomes, including death. We present a clinical vignette of malignant catatonia that required court-ordered ECT, followed by a discussion of practical and legal obstacles to expediting emergent ECT when patients cannot provide consent. We review particularly exacting mandates for involuntary ECT from three states: California, Texas, and New York. As compared to standard practice for other clinical interventions when a patient lacks decision-making capacity, ECT is highly regulated; in some cases, these regulations can interfere with life-saving treatment.
TL;DR: The authors suggest the need for evidence-based outcome studies prior to the institution of further major changes in ACGME requirements, and review representative literature regarding the impact of the changes.
Abstract: In 2003 and again in 2011, the Accreditation Council for Graduate Medical Education (ACGME) instituted increasingly stringent requirements governing resident hours and supervision, with the goals of improving patient safety, resident well-being, and resident education. Although the changes initially stemmed from a catastrophic outcome in a patient treated with psychotropic medications and behavioral restraints, and have been in place over a decade, many psychiatrists are not familiar with these changes and with their potential effects and "side effects" on today's trainees and faculty. The authors review the history leading to these changes, summarize the revised requirements, and review representative literature regarding the impact of the changes. The existing studies of the impact of the new requirements on improving patient safety, resident well-being, and resident education are inconclusive, and most editorials, perspectives, and surveys of faculty and residents reflect a lack of enthusiasm for the changes. They go on to suggest the need for evidence-based outcome studies prior to the institution of further major changes in ACGME requirements.
