However, little is known about what triggers this maladaptive learning in the first place, especially in the early acute stages following injury. We imaged 110 patients within days of whiplash and mild traumatic brain injury and tested whether hippocampal adaptations impart risk for chronic pain one year later. Patients who went on to develop chronic pain one year later showed increased connectivity between the hippocampus and its posterior network, as well as increased network connectivity across posterior hippocampal network nodes and the amygdala bilaterally. This connectivity was linked to anxiety and increased with time lapse from injury to brain scans. Our findings link rapid hippocampal network reorganization with the development of chronic pain. In this study, the authors used imaging to identify increased hippocampal, posterior hippocampal, and amygdala connectivity in people who had experienced whiplash and mild traumatic brain injury and who developed chronic pain one year later.","PeriodicalId":74247,"journal":{"name":"Nature mental health","volume":"2 11","pages":"1362-1370"},"PeriodicalIF":0.0,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite exposure to substantial adversity, many refugees do not develop clinically significant psychopathology. There is a need to understand factors that are associated with good mental health in refugees to inform policy-makers and practitioners working with refugees. Here we aim to synthesize research on factors that are protective (associated with lower negative mental health outcomes) or promotive (associated with higher positive mental health outcomes) among adult refugees living in high-income countries (HICs) and lower-and-middle-income countries (LMICs). We searched four databases (PubMed, Embase, ProQuest and PsycINFO) for relevant studies conducted up until December 2022. A total of 174 articles were included in this review, of which 81% were undertaken in HICs and 19% in LMICs. Key protective and promotive factors were identified across the following domains: sociodemographic characteristics (for example, male gender/sex), environmental factors (for example, financial security, permanent visa status), sociocultural factors (for example, social support, support engagement) and psychological factors (for example, self-efficacy). Based on the outcomes of this review, we provide recommendations for governments, organizations and policymakers working to support good mental health in refugees and propose a research agenda to advance knowledge in the field. Cross-domain investigation and cross-disciplinary collaboration represents a critical next step to understanding and enhancing factors that promote good mental health in refugees. In a systematic review of studies examining protective and promotive factors for mental health in displaced people, the authors identify key sociodemographic, environmental, sociocultural and psychological factors and form recommendations to reinforce best practices for enhancing refugee mental health.","PeriodicalId":74247,"journal":{"name":"Nature mental health","volume":"2 11","pages":"1415-1428"},"PeriodicalIF":0.0,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a systematic review and meta-analysis, the authors find that individuals with a concurrent cluster B personality disorder diagnosis are 2.27 times more likely not to respond to treatment for depression than patients without personality disorders, suggesting the need for more targeted approaches for patients with comorbid personality disorders.","PeriodicalId":74247,"journal":{"name":"Nature mental health","volume":"2 11","pages":"1392-1407"},"PeriodicalIF":0.0,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we conducted an exploratory phenome-wide association study (phenotype n = 1,271–1,697) of polygenic risk scores (PRS) for broad-spectrum psychopathology (that is, compulsive, psychotic, neurodevelopmental and internalizing) in youth most genetically similar to individuals from European reference populations (n = 5,556; ages 9–13) who completed the baseline and/or 2-year follow-up of the ongoing Adolescent Brain Cognitive Development Study. We found that neurodevelopmental and internalizing PRS were significantly associated with phenotypes across multiple domains (neurodevelopmental, 190 and 214 (147 and 165 after pruning correlated phenotypes at an r2 of 0.6); internalizing, 124 and 183 (93 and 131 after pruning) phenotypes at baseline and 2-year follow-up, respectively), whereas compulsive and psychotic PRS showed zero and two significant associations, respectively, after Bonferroni correction. Compulsive, psychotic and neurodevelopmental PRS were further associated with brain structure metrics, with minimal evidence that brain structure indirectly linked PRS to 2-year follow-up outcomes. Genetic variation influencing risk to psychopathology manifests broadly as behaviors, psychopathology symptoms and related risk factors in middle childhood and early adolescence. Using an exploratory phenome-wide association study of polygenic risk scores (PRS) in children aged 9–13 from the Adolescent Brain Cognitive Development Study cohort, the authors identify neurodevelopmental and internalizing PRS associations with multiple phenotypes similar to the constituent GWAS indicators (for example, neurodevelopmental and internalizing traits) as well as cross-trait phenotypes (for example, screen time, cortical volume).","PeriodicalId":74247,"journal":{"name":"Nature mental health","volume":"2 11","pages":"1327-1341"},"PeriodicalIF":0.0,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All participants underwent structured clinical interviews, including an assessment of suicidality in the past month, and completed a functional magnetic resonance imaging scan. There were 238 (41.1%) participants who met criteria for suicidality and 341 (58.9%) were non-suicidal. Task-derived functional connectivity was calculated for 436 brain regions, comprising 8 intrinsic connectivity networks. Participants who were suicidal had decreased connectivity in a network of 143 connections across 86 brain regions. This pattern was characterized primarily by decreased connectivity within the visual, somatomotor and salience networks, between these networks, and also with the default mode and limbic networks. By adopting a transdiagnostic approach with a very large sample of individuals with mood disorders, anxiety and stress and non-psychiatric participants, this study highlights the hypoconnectivity that characterizes suicidality and points to altered connectivity within and between key networks involved in emotional, sensory and cognitive processes that are implicated in suicidal risk.

Further distinction can be drawn between past-centered traumatic recurrences and present-centered trauma-related intrusions. While some argue sensorimotor representations to be building blocks of all memory forms, traumatic memory seems to haunt in the form of unintegrated sensations and actions. This Perspective hypothesizes a neurobiological delineation between these memory forms, where traumatic memory is uniquely characterized by alterations to lower-level and primary sensorimotor processes. The proposed demarcation has implications for legal systems, which assume interrogations of autobiographical and traumatic memory can be methodologically identical. Clinically, first-line treatments for post-traumatic stress disorder have yet to explicitly address sensorimotor processes, where up to half of individuals are non-responsive and 20% drop out. We are left with urgent needs to consider sensorimotor fragmentation of traumatic memory and advance interventions that assimilate these fragments into a past-contextualized autobiography. In this Perspective, the authors review the literature regarding the differences between autobiographical and traumatic memory and introduce sensorimotor-based implications for understanding and treating post-traumatic stress disorder.","PeriodicalId":74247,"journal":{"name":"Nature mental health","volume":"2 10","pages":"1142-1151"},"PeriodicalIF":0.0,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142435939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
