Positive Effect

Eye Movement Desensitization and Reprocessing (EMDR) is a treatment for post-traumatic stressdisorder (PTSD). The technique is known to stimulate the capacity to reprocess maladaptive memoriesthat are thought to be central to this pathology. Here we investigate if EMDR therapy can be used in otherconditions than PTSD. We conducted a systematic literature search on PubMed, ScienceDirect, Scopus, and Web of Science. Wesearched for published empirical findings on EMDR, excluding those centred on trauma and PTSD,published up to 2020. The results were classified by psychiatric categories.   Ninety articles met our research criteria. A positive effect was reported in addictions, somatoformdisorders, sexual dysfunction, eating disorder, disorders of adult personality, mood disorders, reaction tosevere stress, anxiety disorders, performance anxiety, Obsessive-Compulsive Disorder (OCD), pain,neurodegenerative disorders, paedopsychiatry and sleep. The evidence was more consistent in pain, OCD,mood disorders, and reaction to severe stress.EMDR’s efficiency across numerous pathological situations, highlighted the central role of affectivememory in several psychiatric and non-psychiatric conditions. Furthermore, EMDR seems to besuccessful in usually uncooperative (e.g. Dementia) or unproductive cases (e.g. aphasia). Moreover, insome severe medical situations were psychologic distress was an obstacle, EMDR allowed thecontinuation of treatment-as-usual. Our review suggests that it is a safe and economical therapeuticoption, and its effect in non-pathological situations opens new avenues for translational research. Overallmore methodologically rigorous studies are needed.

Da Release

SummaryNumerous neurologic and psychiatric conditions are treated with pharmacological compounds, which lead to an increase of synaptic dopamine (DA) levels. One example is the DA precursor L-3,4-dihydroxyphenylalanine (L-DOPA), which is converted to DA in the presynaptic terminal. If the increase of DA concentrations in the synaptic cleft leads to competition with exogenous radioligands for presynaptic binding sites, this may have implications for DA transporter (DAT) imaging studies in patients under DAergic medication.This paper gives an overview on those findings, which, so far, have been obtained on DAT binding in human Parkinson’s disease after treatment with L-DOPA. Findings, moreover, are related to results obtained on rats, mice or non-human primates. Results indicate that DAT imaging may be reduced in the striata of healthy animals, in the unlesioned striata of animal models of unilateral Parkinson’s disease and in less severly impaired striata of Parkinsonian patients, if animal or human subjects are under acute or subchronic treatment with L-DOPA. If also striatal DAT binding is susceptible to alterations of synaptic DA levels, this may allow to quantify DA reuptake in analogy to DA release by assessing the competition between endogenous DA and the administered exogenous DAT radioligand.

The N-methyl-D-aspartate receptor (NMDAR) is a member of the ionotropic glutamate receptor (iGluR) family that plays a crucial role in brain signalling and development. NMDARs are nonselective cation channels that are involved with the propagation of excitatory neurotransmission signals with important effects on synaptic plasticity. NMDARs are functionally and structurally complex receptors, they exist as a family of subtypes each with its own unique pharmacological properties. Their implication in a variety of neurological and psychiatric conditions means they have been a focus of research for many decades. Disruption of NMDAR-related signalling is known to adversely affect higherorder cognitive functions (e.g. learning and memory) and the search for molecules that can recover (or even enhance) receptor output is a current strategy for CNS drug discovery. A number of positive allosteric modulators (PAMs) that specifically attempt to overcome NMDAR hypofunction have been discovered. They include various chemotypes that have been found to bind to several different binding sites within the receptor. The heterogeneity of chemotype, binding site and NMDAR subtype provide a broad landscape of ongoing opportunities to uncover new features of NMDAR pharmacology. Research on NMDARs continues to provide novel mechanistic insights into receptor activation and this review will provide a high-level overview of the research area and discuss the various chemical classes of PAMs discovered so far.

The Impact

Women are more likely than men to meet lifetime criteria for an anxiety disorder. Moreover, anxiety is a risk factor for the development of other psychiatric conditions, including major depression. Numerous studies have identified evidence of sex differences in anxiety disorders, and there is considerable research concerning factors that may contribute to vulnerability for anxiety in females. In addition to psychosocial influences, biological components such as the female reproductive hormone cycle have also been implicated. Although psychotropic medication is more likely to be prescribed to women, there is little controlled data available concerning sex differences in the efficacy and/or tolerability of pharmacotherapy in anxiety disorders. This chapter provides an overview of the impact of gender in the epidemiology, phenomenology, course, and treatment response in generalized anxiety disorder (GAD), social anxiety disorder (SAD), posttraumatic stress disorder (PTSD), panic disorder (PD), and obsessive-compulsive disorder (OCD).

And Behavior

Psychosis spectrum disorders (PSDs) are complex, highly heritable psychiatric conditions with high economic and societal costs. PSDs have historically been conceptualized as neurocognitive disorders in which psychotic episodes and impairments in social and emotional functioning are attributed to deficits in neurocognition. Although cognitive pathways play an important role in the etiology and presentation of PSDs, recent research suggests that interrelations between cognition and emotion are highly relevant. Moreover, aberrant emotion regulation likely plays a significant role in the presentation of PSDs. Emotion dysregulation (ED) may underlie and exacerbate both negative and positive symptoms in PSDs, such as blunted affect, avolition, disorganized speech and behavior, poor social cognition, and delusions and hallucinations. Advances in measurement of emotion dysregulation—including self-reports, behavioral paradigms, neuroimaging paradigms, and neurophysiological assessment—have informed etiological models of emotion dysregulation in PSDs. This chapter reviews research on emotion regulation and dysregulation in PSDs. Notably, more severe presentations of emotion symptoms and greater emotion regulation impairments are associated with worse outcomes in PSDs. It may therefore be the case that focusing on ED as an early risk factor and intervention target could improve outcomes and prevention approaches for psychotic disorders.

Recent research and clinical attention devoted to co-occurring psychiatric conditions within autism spectrum disorder (ASD) has led to significant advances in the understanding of and ability to assess and treat co-occurring problems effectively. This chapter summarizes those advances while also highlighting the substantial gaps that remain in the understanding of co-occurring problems in people with ASD. The chapter provides recommendations for future research directions in the areas of etiology, developmental course, assessment, and treatment. It also offers suggestions for improving the representativeness of research participants and strengthening community–academic partnerships in this important field of study.

And Gender

Gender diversity refers to gender expressions and/or gender identity experiences that vary from the common experiences of gender. Gender-diverse people may be gender nonconforming, gender nonbinary, gender fluid, gender exploring, transgender, and so forth. Some gender-diverse individuals experience gender dysphoria and/or gender incongruence and may require gender-affirming supports, including gender-affirming medical interventions. The co-occurrence of autism and gender diversity has been highlighted in a series of studies internationally as well as through rich community expressions. Studies in gender-referred individuals reveal high rates of autism traits as well as high rates of existing autism diagnoses. Studies in autistic populations reveal greater gender diversity characteristics. The long-term course of gender diversity in autistic individuals is poorly understood. Clinical guidelines have been developed for adolescents with the co-occurrence, but much work remains: No gender-related measures have been developed and tested for use in neurodiverse populations, no programs exist to support gender-diverse neurodiverse adults, and little is known about co-occurring mental health profiles, risks, or protective factors for people with the co-occurrence. The inclusion of this chapter on co-occurring autism and gender diversity within a book on “co-occurring psychiatric conditions” is problematic, because gender diversity is not a “psychiatric condition,” but instead a form of human diversity. The diagnosis of Gender Dysphoria is useful only insomuch as it allows individuals to obtain necessary gender-related supports. The authors’ choice to include this chapter in this book reflects a compromise, motivated by the need for educating both autism and gender specialists in this common co-occurrence.

AbstractDelusions are often portrayed as paradigmatic instances of incomprehensibility and meaninglessness. Here we investigate the relationship between delusions and meaning from a philosophical perspective, integrating arguments and evidence from cognitive psychology and phenomenological psychopathology. We review some of the empirical and philosophical literature relevant to two claims about delusions and meaning: (1) delusions are meaningful, despite being described as irrational and implausible beliefs; (2) some delusions can also enhance the sense that one’s life is meaningful, supporting agency and creativity in some circumstances. Delusions are not incomprehensible representations of reality. Rather, they can help make sense of one’s unusual experiences and in some circumstances even support one’s endeavours, albeit temporarily and imperfectly. Acknowledging that delusions have meaning and can also give meaning to people’s lives has implications for our understanding of psychotic symptoms and for addressing the stigma associated with psychiatric conditions.
