Culture dissociative disorder

BACKGROUND: Ketamine is the prototypal rapid-acting antidepressant (RAAD) for TRD with approved indication for esketamine-nasal spray (ESK-NS). Distinctly, arketamine (R-KET) demonstrates enhanced antidepressant effects and neuroplasticity changes compared to esketamine, with fewer dissociative side effects and abuse potential. This study focuses on R-ketamine's therapeutic implications, safety, and tolerability in TRD treatment. METHODS: We report on a year-long follow-up of three TRD patients post-single IV R-KET administration...

Previous studies showed that dissociation and dissociative disorders (DDs) are prevalent and are associated with considerable individual and social consequences. There are ongoing debates regarding whether dissociation is a response to betrayal trauma across cultures and whether dissociation can be explained by maladaptive coping. Additionally, little is known about the clinical features of individuals with DDs in the Chinese context. This study aimed to investigate the relationship between trauma, emotional regulation, coping, and dissociation...

INTRODUCTION: Dissociative disorder patients often present with sudden and embarrassing symptoms, and it is difficult for the patient and care giver to understand initially, recognize the need for help and reach for appropriate treatment timely. This can result in high risk of engaging in dangerous behaviors such as self-harm and suicidal acts, impaired global functioning, and poor quality of life. Knowledge about the types of barriers which are there in treatment seeking, can help in planning strategies for their removal and to facilitate the treatment process...

BACKGROUND: Depression is a prevalent mood disorder during the perioperative period, with both preoperative concurrent depression and new-onset postoperative depression impacting postoperative recovery. Recent studies have indicated that the dissociative anesthetic esketamine may alleviate perioperative depressive symptoms. OBJECTIVE: This meta-analysis aimed to assess the efficacy and safety of esketamine in treating perioperative depression. METHODS: We selected randomized controlled trials comparing esketamine to placebo in terms of postoperative depressive symptoms...

The Detachment and Compartmentalization Inventory (DCI) is a valid and reliable self-report instrument that assesses these two distinct forms of dissociative symptoms. However, there is limited research on the cross-cultural validation of the DCI. Therefore, this study aimed to develop an Italian translation of the DCI and examine its internal structure and psychometric properties (including internal consistency, convergent validity, and test-retest reliability) within an Italian-speaking community sample. The sample consisted of 1276 adults (887 females; mean age: 29...

The ionotropic glutamate delta receptor GluD1, encoded by the GRID1 gene, is involved in synapse formation, function, and plasticity. GluD1 does not bind glutamate, but instead cerebellin and D-serine, which allow the formation of trans-synaptic bridges, and trigger transmembrane signaling. Despite wide expression in the nervous system, pathogenic GRID1 variants have not been characterized in humans so far. We report homozygous missense GRID1 variants in five individuals from two unrelated consanguineous families presenting with intellectual disability and spastic paraplegia, without (p...

Clinical conversations surrounding the continuation or limitation of life-sustaining treatments (LLST) are both challenging and tragically necessary for patients with Disorders of Consciousness (DoC) following severe brain injury. Divergent cultural, philosophical, and religious perspectives contribute to vast heterogeneity in clinical approaches to LLST - as reflected in regional differences and inter-clinician variability. Here we provide an ethical analysis of factors that inform LLST decisions among patients with DoC...

Adverse childhood experiences (ACEs) are well-established risk factors for psychotic symptoms. This study replicated the relationship between ACEs and positive symptoms of psychosis in the Asian context and explored the moderating effect of dissociation. We analyzed data from 1439 high school students in China who completed validated measures of ACEs, positive symptoms of psychosis, and dissociative symptoms. The positive relationship between ACEs and psychotic symptoms was confirmed in our sample (r =0.244, p <0...

Depression is a major public health concern. Recent studies suggest that dissociative symptoms are associated with depressive symptoms, and the concept of "dissociative depression" has been proposed. Yet, only cross-sectional evidence is available in the literature. This study examined the bidirectional relationship between dissociative and depressive symptoms through the use of screening tools in a sample of Chinese young adults (N = 340) over four months. Baseline dissociative symptoms predicted depressive symptoms at follow-up (β = ...

The retina is the sensory tissue responsible for the first stages of visual processing, with a conserved anatomy and functional architecture among vertebrates. To date, retinal eye diseases, such as diabetic retinopathy, age-related macular degeneration, retinitis pigmentosa, glaucoma, and others, affect nearly 170 million people worldwide, resulting in vision loss and blindness. To tackle retinal disorders, the developing retina has been explored as a versatile model to study intercellular signaling, as it presents a broad neurochemical repertoire that has been approached in the last decades in terms of signaling and diseases...

BACKGROUND: The COVID-19 pandemic and related policies have amplified the vulnerability of adolescents to the development of posttraumatic stress disorder (PTSD) and dissociation symptoms. This study sought to explore the profile patterns and psychopathological characteristics of co-occurring PTSD and dissociation symptoms in Chinese adolescents. METHODS: A total of 57,984 junior and senior high school students in Deyang City, China were recruited between July 13 and July 19, 2020...

Dissociative disorders have been present in our society since time immemorial, with culture, society, and spiritual beliefs playing a major part. It went through many changes from its name and what it constituted. Diagnosis can be made based on the International Classification of Diseases (ICD) 10, Diagnostic and Statistical Manual of Mental Disorders (DSM) 5, and now the current International Classification of Diseases (ICD) 11 criteria. One of its constituents is trance and possession disorder which is one of the main obstacles faced by psychiatrists in Indian society...

Bidirectional transport of cargos along the axon is critical for maintaining functional synapses, neural connectivity, and healthy neurons. Axonal transport is disrupted in multiple neurodegenerative diseases, and projection neurons are particularly vulnerable because of the need to transport cellular materials over long distances and sustain substantial axonal mass. Pathological modifications of several disease-related proteins negatively affect transport, including tau, amyloid-β, α-synuclein, superoxide dismutase, and huntingtin, providing a potential common mechanism by which pathological proteins exert toxicity in disease...

Background: The cAMP response element-binding protein (CREB) and CREB-regulated transcription coactivators (CRTCs) cooperate in the transcriptional activation of microphthalmia-associated transcription factor subtype M (MITF-M) that is a master regulator in the biogenesis, pigmentation and transfer of melanosomes at epidermal melanocytes. Here, we propose the targeting of phosphorylation circuits on CREB and CRTCs in the expression of MITF-M as the rationale to prevent skin hyperpigmentation by elucidating the inhibitory activity and mechanism of yakuchinone A (Yaku A) on facultative melanogenesis...

Substance abuse is a serious problem in our society. In particular, household or parental substance abuse could lead to adverse childhood experiences for the affected children. However, little is known about the prevalence of substance abuse among parents, especially in Asian societies. Moreover, although the trauma model of addiction has significant implications for the prevention and treatment of substance abuse, most evidence comes from Western samples. To address these knowledge gaps, we examined the prevalence of substance abuse in a sample of mothers in Taiwan and tested the trauma model of substance abuse...

BACKGROUND: CASK-related neurodevelopmental disorders are untreatable. Affected children show variable severity, with microcephaly, intellectual disability (ID), and short stature as common features. X-linked human CASK shows dosage sensitivity with haploinsufficiency in females. CASK protein has multiple domains, binding partners, and proposed functions at synapses and in the nucleus. Human and Drosophila CASK show high amino-acid-sequence similarity in all functional domains. Flies homozygous for a hypomorphic CASK mutation (∆18) have motor and cognitive deficits...

The Dissociative Identity Disorder has undergone significant transformations over the years. Once regarded as a rare condition, it gained popularity in the 1980s in the United States following the publication of a book on the subject, only to subsequently wane due to extensive controversies. Presently, we are witnessing a resurgence of adolescents who believe they may be afflicted by this disorder. This article delves into the changes that have occurred since the initial surge in 1980, with a particular focus on the role of social media in the dissemination of Dissociative Identity Disorder...

BACKGROUND: Psychiatric disorders differ in frequency and symptoms based on the cultural and ethnic background of patients. This can make diagnosing and treating patients challenging globally. In Pakistan, most psychiatric patients report multiple somatic complaints. Our goal was to investigate the causes of these complaints, identify common psychiatric conditions, and analyze their various manifestations in clinical practice. We also aimed to identify ways to improve the quality of care provided to our patients...

In neurodegenerative diseases, the condensation of FUS and TDP-43 with RNA granules in neurons is linked to pathology, including synaptic disorders. However, the effects of FUS and TDP-43 on RNA granule factors remain unclear. Here, using primary cultured neurons from the mouse cerebral cortex, we show that excess cytoplasmic FUS and TDP-43 accumulated in dendritic RNA granules, where they increased the dynamics of a scaffold protein RNG105/caprin1 and dissociated it from the granules. This coincided with reduced levels of mRNA and translation around the granules and synaptic loss in dendrites...
