Recent studies proposed a general psychopathology factor underlying common comorbidities among psychiatric disorders. However, its neurobiological mechanisms and generalizability remain elusive. In this study, we used a large longitudinal neuroimaging cohort from adolescence to young adulthood (IMAGEN) to define a neuropsychopathological (NP) factor across externalizing and internalizing symptoms using multitask connectomes. We demonstrate that this NP factor might represent a unified, genetically determined, delayed development of the prefrontal cortex that further leads to poor executive function. We also show this NP factor to be reproducible in multiple developmental periods, from preadolescence to early adulthood, and generalizable to the resting-state connectome and clinical samples (the ADHD-200 Sample and the STRATIFY & ESTRA Project). In conclusion, we identify a reproducible and general neural basis underlying symptoms of multiple mental health disorders, bridging multidimensional evidence from behavioral, neuroimaging and genetic substrates. These findings may help to develop new therapeutic interventions for psychiatric comorbidities. Evidence from large longitudinal neuroimaging cohorts, which include genetic and behavioral data, suggest a common neural basis for symptoms seen across multiple psychiatric disorders.

Purpose This systematic review was performed to identify all relevant health-related quality of life (HRQoL) issues associated with COVID-19. Methods A systematic literature search was undertaken in April 2020. In four teams of three reviewers each, all abstracts were independently reviewed for inclusion by two reviewers. Using a pre-defined checklist of 93 criteria for each publication, data extraction was performed independently by two reviewers and subsequently compared and discussed. If necessary, a third reviewer resolved any discrepancies. The search was updated in February 2021 to retrieve new publications on HRQoL issues including issues related to the long-term consequences of COVID-19. Results The search in April 2020 identified 3342 potentially relevant publications, and 339 publications were selected for full-text review and data extraction. We identified 75 distinct symptoms and other HRQoL issues categorized into 12 thematic areas; from general symptoms such as fever, myalgia, and fatigue, to neurological and psychological issues. The updated search revealed three extra issues experienced during active disease and long-term problems with fatigue, psychological issues and impaired cognitive function. Conclusion This first comprehensive systematic review provides a detailed overview of the wide range of HRQoL issues experienced by patients with COVID-19 throughout the course of the disease. It demonstrates the devastating impact of the disease and provides critically important information for clinicians, to enable them to better recognize the disease and to provide knowledge important for treatment and follow-up. The results provided the foundation for the international development of a COVID-19 specific patient-reported HRQoL questionnaire.

The goal of the present meta-analysis was to compare associations of harsh parenting with internalizing and externalizing symptoms across regions of the globe and ethnic groups, and to search for moderator effects of indicators of cultural normativeness of harsh parenting. The systematic search in electronic databases and cross-referencing identified 971 studies. Random-effects meta-analyses were computed on bivariate and cross-lagged associations. Harsh parenting was associated with more internalizing and externalizing symptoms in all assessed regions of the globe and in all compared ethnic groups within western countries. Cross-lagged statistical effects of harsh parenting on change in child symptoms were found in North America, Western Europe, Latin America, East Asia, South-East Asia, and North Africa/the Arabian Peninsula, while there were no data from Eastern Europe. In line with the cultural normativeness hypothesis, a few moderating effects of the legal ban of physical punishment of children, acceptance and prevalence of physical punishment, and individualism-collectivism were identified. Externalizing symptoms predicted a stronger increase in harsh parenting if physical punishment was more accepted in the individual country. However, national levels of acceptance of physical punishment did not affect associations of harsh parenting with change in child outcomes. Although most associations of harsh parenting with child symptoms were statistically small (bivariate associations) or very small (cross-lagged associations), it is concluded that parents across the globe should be recommended to avoid harsh parenting. More longitudinal studies are needed for analyzing regional differences in parent and child effects. Highlights Parenting effects varied, in part, by the cultural normativeness of the parental behavior. Harsh parenting was associated with more child symptoms across the globe, and in different ethnic groups. Externalizing symptoms predicted stronger increases in harsh parenting in countries where physical punishment is more accepted. Cultural acceptance of physical punishment did not moderate association of harsh parenting with change in externalizing symptoms. Similarly, cultural acceptance did not moderate association of harsh parenting with internalizing symptoms.

Evidence suggests that dissociation is associated with psychotic experiences, particularly hallucinations, but also other symptoms. However, until now, symptom-specific relationships with dissociation have not been comprehensively synthesized. This is the first prospectively registered (CRD42017058214) meta-analysis to quantify the magnitude of association between dissociative experiences and all symptoms of psychosis. MEDLINE, PsycINFO, PubMed, and Scopus databases were searched using exhaustive terms denoting dissociation and psychotic symptoms. We included both nonclinical (58 studies; 16 557 participants) and clinical (46 studies; 3879 patient participants) samples and evaluated study quality. Ninety-three eligible articles considering 20 436 participants were retained for analysis. There was a robust association between dissociation and clinical and nonclinical positive psychotic symptoms (r = .437; 95%CI: .386 −.486), with the observed effect larger in nonclinical studies. Symptom-specific associations were also evident across clinical and nonclinical studies, and included significant summary effects for hallucinations (r = .461; 95%CI: .386 −.531), delusions (r = .418; 95%CI: .370 −.464), paranoia (r = .447; 95%CI: .393 −.499), and disorganization (r = .346; 95%CI: .249 −.436). Associations with negative symptoms were small and, in some cases, not significant. Overall, these findings confirm that dissociative phenomena are not only robustly related to hallucinations but also to multiple positive symptoms, and less robustly related to negative symptoms. Our findings are consistent with proposals that suggest certain psychotic symptoms might be better conceptualized as dissociative in nature and support the development of interventions targeting dissociation in formulating and treating psychotic experiences.

Complex post-traumatic stress disorder (complex PTSD) is a severe mental disorder that emerges in response to traumatic life events. Complex PTSD is characterised by three core post-traumatic symptom clusters, along with chronic and pervasive disturbances in emotion regulation, identity, and relationships. Complex PTSD has been adopted as a new diagnosis in the ICD-11. Individuals with complex PTSD typically have sustained or multiple exposures to trauma, such as childhood abuse and domestic or community violence. The disorder has a 1–8% population prevalence and up to 50% prevalence in mental health facilities. Progress in diagnostics, assessment, and differentiation from post-traumatic stress disorder and borderline personality disorder is reported, along with assessment and treatment of children and adolescents. Studies recommend multicomponent therapies starting with a focus on safety, psychoeducation, and patient-provider collaboration, and treatment components that include self-regulatory strategies and trauma-focused interventions.

Mental health problems often involve clusters of symptoms that include subjective (conscious) experiences as well as behavioral and/or physiological responses. Because the bodily responses are readily measured objectively, these have come to be emphasized when developing treatments and assessing their effectiveness. On the other hand, the subjective experience of the patient reported during a clinical interview is often viewed as a weak correlate of psychopathology. To the extent that subjective symptoms are related to the underlying problem, it is often assumed that they will be taken care of if the more objective behavioral and physiological symptoms are properly treated. Decades of research on anxiety disorders, however, show that behavioral and physiological symptoms do not correlate as strongly with subjective experiences as is typically assumed. Further, the treatments developed using more objective symptoms as a marker of psychopathology have mostly been disappointing in effectiveness. Given that “mental” disorders are named for, and defined by, their subjective mental qualities, it is perhaps not surprising, in retrospect, that treatments that have sidelined mental qualities have not been especially effective. These negative attitudes about subjective experience took root in psychiatry and allied fields decades ago when there were few avenues for scientifically studying subjective experience. Today, however, cognitive neuroscience research on consciousness is thriving, and offers a viable and novel scientific approach that could help achieve a deeper understanding of mental disorders and their treatment.

Cognitive symptoms (CS) belong to the most common manifestations of the Post COVID-19 (PC) condition. We sought to objectify CS in PC patients using routine diagnostic assessments: neurocognitive testing (NCT) and brain imaging (BI). Further, we investigated possible associations of CS with patient reported outcomes (PROs), and risk factors for developing CS. Clinical data and PROs of 315 PC patients were assessed at a mean of 6 months after SARS-CoV-2 infection. 231 (73.3%) patients reported any sort of CS. Among them, 78 underwent NCT and 55 received BI. In NCT, the cognitive domains most affected were the working memory, attention, and concentration. Nonetheless, pathological thresholds were exceeded only in few cases. Neurocognitive performance did not differ significantly between patients complaining of severe (n = 26) versus non-severe (n = 52) CS. BI findings were abnormal in 8 (14.5%) cases with CS but were most likely not related to PC. Patients reporting high severity of CS scored worse in the PHQ-9, FSS, WHOQOL-BREF, were more likely to report impaired sleep, and had a higher prevalence of psychiatric diagnoses. Overall, NCT could confirm mild impairment in some but not all PC patients with CS, while BI studies were abnormal in only few cases. CS severity did not affect NCT results, but severe CS were associated with symptoms of depression (PHQ-9), fatigue (FSS), reduced quality of life (WHOQOL-BREF) and higher prevalence of psychiatric illnesses. These findings support the importance of NCT, BI, and neuro-psychological assessment in the work-up of PC patients reporting CS.

Urban-living individuals are exposed to many environmental factors that may combine and interact to influence mental health. While individual factors of an urban environment have been investigated in isolation, no attempt has been made to model how complex, real-life exposure to living in the city relates to brain and mental health, and how this is moderated by genetic factors. Using the data of 156,075 participants from the UK Biobank, we carried out sparse canonical correlation analyses to investigate the relationships between urban environments and psychiatric symptoms. We found an environmental profile of social deprivation, air pollution, street network and urban land-use density that was positively correlated with an affective symptom group ( r  = 0.22, P perm  < 0.001), mediated by brain volume differences consistent with reward processing, and moderated by genes enriched for stress response, including CRHR1 , explaining 2.01% of the variance in brain volume differences. Protective factors such as greenness and generous destination accessibility were negatively correlated with an anxiety symptom group ( r  = 0.10, P perm  < 0.001), mediated by brain regions necessary for emotion regulation and moderated by EXD3 , explaining 1.65% of the variance. The third urban environmental profile was correlated with an emotional instability symptom group ( r  = 0.03, P perm  < 0.001). Our findings suggest that different environmental profiles of urban living may influence specific psychiatric symptom groups through distinct neurobiological pathways. Analyses of data from the UK Biobank reveal different urban living environments that are associated with affective, anxiety and emotional instability symptom groups and mediated by distinct neurological and genetic pathways in adults.

Hypothalamic-pituitary-adrenal (HPA)-axis hyperactivity and inflammation are thought to be prominent in the aetiology of depression. Although meta-analyses have confirmed this relationship, there is considerable variability in the effect sizes across studies. This could be attributed to a differential role of such biological systems in somatic versus cognitive-affective depressive symptoms which remains largely unexplored. Furthermore, most longitudinal research to date has focused on transient rather than persistent depressive symptoms. In the current study, we investigated the associations of hair cortisol and plasma C-reactive protein (CRP) with the longitudinal persistence and dimensions (cognitive-affective versus somatic) of depressive symptoms over a 14-year period using Trait‐State‐Occasion (TSO) structural equation modelling. The data came from a large sample of older adults from the English Longitudinal Study of Ageing. Depressive symptoms were assessed from wave 1 (2002–03) to wave 8 (2016–17). Hair cortisol (N = 4761) and plasma CRP (N = 5784) were measured in wave 6 (2012–13). Covariates included demographic, socioeconomic, lifestyle, chronic disease, and medication data. Our results revealed that higher cortisol and CRP levels were significantly associated with persistent depressive symptoms across the study period. Notably, both biomarkers exhibited stronger relationships with somatic than with cognitive-affective symptoms. The associations with somatic symptoms were also independent of relevant confounding factors. In contrast, their associations with cognitive-affective symptoms were weak after adjustment for all covariates. These distinct associations reveal the importance of considering symptom-specific effects in future studies on pathophysiological mechanisms. Ultimately, this will have the potential to advance the search for biomarkers of depression and facilitate more targeted treatments.

Background and objectives Non-polyglutamine CACNA1A variants underlie an extremely variable phenotypic spectrum encompassing developmental delay, hemiplegic migraine, epilepsy, psychiatric symptoms, episodic and chronic cerebellar signs. We provide our experience with the long-term follow-up of CACNA1A patients and their response to interval therapy. Methods Patients with genetically confirmed non-polyglutamine CACNA1A disease were prospectively followed at the Center for Rare Movement Disorders of the Medical University of Innsbruck from 2004 to 2024. Results We recruited 41 subjects with non-polyglutamine CACNA1A disease, of which 38 (93%) familial cases. The mean age at the first examination was 35 ± 22 years. Disease onset was in the childhood/adolescence in 31/41 patients (76%). Developmental delay and episodic symptoms were the first disease manifestation in 9/41 (22%) and 32/41 (78%) patients respectively. Chronic neurological signs encompassed a cerebellar syndrome in 35/41 (85%), which showed almost no progression during the observation period, as well as cognitive deficits in 9/20 (45%, MOCA test score < 26), psychiatric and behavioral symptoms in 11/41(27%). Seizures occurred in two patients concomitant to severe hemiplegic migraine. At the last visit, 27/41 patients (66%) required an interval prophylaxis (including acetazolamide, flunarizine, 4-aminopyridine, topiramate), which was efficacious in reducing the frequency and severity of episodic symptoms in all cases. In one patient in his 70ies with progressively therapy resistant hemiplegic migraine, treatment with the anti-CGRP antibody galcanezumab successfully reduced the frequency of migraine days from 4 to 1/month. Conclusions Non-polyglutamine CACNA1A disease show an evolving age-dependent presentation. Interval prophylaxis is effective in reducing the burden of episodic symptoms.
