A balanced diet is relevant for neuropsychological functioning. We aimed to analyze the association between dietary patterns and neuropsychological outcomes in a sample of healthy adolescents of the Walnuts Smart Snack (WSS) cohort from Barcelona city. We performed principal components analysis (PCA) to determine dietary patterns in the adolescent sample using a food frequency questionnaire (60 items). Multiple linear regression models were performed to analyze the association between PCA dietary patterns with neuropsychological outcomes: Strengths and Difficulties (SDQ) externalizing and internalizing scores, Attention Network Test (ANT) Impulsivity Index and Emotional Recognition Task (ERT) scores...

Accumulating evidence suggests a role for the tryptophan-kynurenine pathway (TKP) in the psychopathology of major depressive disorder (MDD). Abnormal inflammatory profile and production of TKP neurotoxic metabolites appear more pronounced in MDD with suicidality. Progress in understanding the neurobiology of MDD in adolescents lags significantly behind that in adults due to limited empirical evidence. Aims of this study was to investigate the association between inflammation, TKP, and suicidality in adolescent depression...

The presence of callous-unemotional (CU) traits may not be unique to conduct disorder (CD) but also extend to oppositional defiant disorder (ODD). While a distinct neurocognitive profile characterizes CU traits, it remains unclear whether this CU-related neurocognitive profile differs between youth with CD and ODD. This study investigated whether CU traits moderate the relationship between inhibitory control and CD or ODD symptoms. We leveraged computational modeling to decompose task-based inhibitory control in a sample of 200 children (59...

Mentalization-based interventions (MBIs) have been increasingly applied in school settings to support the social-emotional development and mental health of children and adolescents. This systematic review aimed to synthesize the evidence on the effectiveness of MBIs implemented in educational contexts for students aged 6-18 years. A comprehensive search was conducted in PsychInfo, MEDLINE, EMBASE, Web of Science, and ERIC databases from inception to October 2023. The search strategy combined terms related to mentalization, school-based interventions, and the target age group...

We assessed genetic and environmental influences on social isolation across childhood and the overlap between social isolation and mental health symptoms including depression symptoms, conduct problems, and psychotic-like experiences from adolescence to young adulthood. Participants included 2,232 children from the Environmental Risk Longitudinal Twin Study. Social isolation was measured at ages 5, 7, 10, 12, and 18. A Cholesky decomposition was specified to estimate the genetic and environmental influences on social isolation across ages 5, 7, 10, and 12...

Thiamine is an essential vitamin that plays a crucial role in many biochemical processes in the body. Anorexia nervosa (AN) is one potential cause of a state of deficiency which can result in grave medical sequelae. There is limited available evidence of the prevalence of thiamine deficiency in patients who suffer from AN. The current study aimed to systematically review all available evidence on the prevalence of thiamine deficiency in cohorts with AN. Studies were included where thiamine status in a group of participants with AN was measured, either through self-reporting or objective measurement...

Children and adolescents with severe or relapsing major depressive disorder (MDD) may require long-term antidepressant use, but safety and tolerability data on long-term treatment are limited. In a randomized, placebo-controlled trial in children and another in adolescents, vortioxetine and placebo groups showed improvement in MDD symptoms without statistically significant differences between groups. To gain insights on long-term safety and tolerability of vortioxetine in pediatric patients, participants from these two studies were enrolled in two long-term extension studies: 6 months (NCT02871297) followed by another 18 months (NCT03108625)...

Existing literature strongly supports the idea that children with primary nocturnal enuresis (PNE) have brainstem abnormalities. However, the connection between pre-micturition arousal responses and brain functional connectivities is still not clearly defined. Our study investigated the correlation between the gradations of micturition desire-awakening (MDA) functionality and the functional connectivity of the midbrain periaqueductal gray (PAG), a pivotal brainstem hub implicated in the neural regulation of micturition in humans...

The current study examined attention-deficit/hyperactivity disorder (ADHD) dimensions and cognitive disengagement syndrome (CDS) symptoms in relation to self-injurious thoughts and behaviors (SITBs) in an early adolescent sample. Participants were 341 adolescents ages 10-12 years (52.2% female; 37.8% people of color) recruited from the community. Caregivers reported on CDS and ADHD symptoms. Adolescents completed a rating scale and were administered an interview assessing SITBs. We estimated associations using logistic regression in a stepped fashion: (1) no adjustment, (2) adjustment for sex, race, family income, and psychotropic medication use, and (3) further adjustment for depressive symptoms...

Parenting a child on the autism spectrum presents particular challenges that can lead to increased stress, anxiety, and depression among family members. Therefore, we aimed to investigate the prevalence of mental disorders in first-degree relatives of individuals on the autism spectrum. This article adheres to the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols (PRISMA-P) guidelines, including studies indexed in PubMed/Medline, Embase, PsycINFO, Biblioteca Virtual em Saúde (BVS), and SciELO...

Because the offspring of parents with an affective disorder (OAD) are at high risk for developing mental disorders, and persons with an affective disorder (AD) show dysfunctional hypothalamic-pituitary-adrenal (HPA) axis activity, changes in HPA functioning in OAD might be an etiological risk factor that precedes the development of ADs. The primary aim of the meta-analysis was to quantitatively summarize the existing data on different indices of diurnal cortisol in the OAD. The secondary aim was to explore potential moderators of this relation...

Paranoia is the erroneous idea that people are targeting you for harm, and the cognitive model suggests that symptoms increase with emotional and relational distress. A factor potentially associated with paranoia is mistrust, a milder form of suspiciousness. This study investigated the longitudinal course of non-clinical paranoia in a sample of 739 students (age range 10-12 at baseline assessment, 12-14 at second assessment) using data from the Social Mistrust Scale (SMS) and the paranoia subscale of the Specific Psychotic Experiences Questionnaire (SPEQ)...

Social anxiety disorder (SAD) is one of the most common psychiatric disorders in adolescents. The heterogeneity of both symptoms and etiology is an essential source of difficulties in the treatment and prevention of SAD. The study aimed to identify subtypes of adolescent SAD based on etiology-related phenotype dimensions and examine symptom and brain associations of the subtypes. We used a deeply phenotyped sample (47 phenotype subscales from 13 measures) of adolescents with SAD (n = 196) and healthy controls (n = 109) to extract etiology-relevant risk factors, based on which we identified subtypes of SAD...

This study investigated sociodemographic and clinical factors influencing help-seeking attitudes and behavior among adolescents with mental health problems. As part of the ProHEAD ("Promoting Help-seeking using E-technology for ADolescents") consortium a school-based, online assessment of sociodemographic information, psychopathology, risk-taking and self-harming behavior, help-seeking attitudes and behavior, and barriers to help-seeking was conducted in adolescents aged ≥ 12 years recruited from randomly selected schools in five regions of Germany...

Family therapy for eating disorders (ED) is well-established and represents the treatment choice for ED in children and adolescents according to guidelines, with cognitive behavior therapy (CBT) as a second line treatment. There is limited knowledge about how these treatments work in routine clinical care. The goal of the present meta-analysis is to investigate the effectiveness of family therapy and CBT for various EDs in children and adolescents when carried out in routine clinical care. Ovid MEDLINE, Embase OVID, and PsycINFO were searched for articles published until December 2023...

Maternal depression promotes maternal inflammation and the risk of neurodevelopmental disorder in offspring, but the role of inflammation on the association between depression and neurodevelopment in offspring has not been extensively studied in humans. This study aims to examine the mediating role of maternal inflammation on the relationship between maternal depression and neurodevelopment in infants. 146 mother-child pairs were identified from Tianjin Maternal and Child Health Education and Service Cohort (Tianjin MCHESC)...
