The Role of Dietary Patterns and Nutritional Supplements in the Management of Mental Disorders in Children and Adolescents: An Umbrella Review of Meta-Analyses: Le rôle des habitudes alimentaires et des suppléments nutritionnels dans la prise en charge des troubles mentaux chez les enfants et les adolescents : une méta-revue de méta-analyses.

OBJECTIVE: In recent years, the relationship between nutrition and mental health has gained considerable interest. We identified, synthesized, and appraised all meta--analyses of randomized controlled trials (RCTs) and observational studies reporting on the efficacy of dietary patterns and nutrient supplements in the prevention and treatment of mental disorders in children and adolescents. METHODS: Systematic research in MEDLINE, PsycINFO, Scopus, and Cochrane Database of Systematic Reviews was completed on 8 January 2024. RESULTS: Our research found 24 meta-analyses: 14 on RCTs, 8 on observational studies, and 2 combining both. Emerging evidence suggests that omega-3, in particular eicosapentaenoic acid, and Vitamin D may have adjunctive benefits in the treatment of attention deficit hyperactivity disorder (ADHD), while no evidence was found for autism spectrum disorder (ASD). Observational data also indicated that prenatal folic acid supplementation (>400 µg daily) was associated with a reduced risk of ASD in offspring. In terms of dietary habits, several meta-analyses of observational data revealed that healthy dietary patterns (rich in fruits, vegetables, and fibre, low in saturated fats) during the prenatal period, childhood, and adolescence were linked to a significantly reduced risk of internalizing disorders and externalizing disorders. Conversely, unhealthy dietary habits (high in sugars, saturated animal fats, and industrial foods, low in fruits, vegetables, and fibre) are associated with an elevated risk of these mental health issues. However, the number of available studies on dietary interventions for the treatment of depression, ASD, and ADHD was limited, and the results obtained were either nonsignificant or contradictory. CONCLUSION: Our findings emphasize the need to establish clear causal relationships between dietary habits and the risk of mental illness in children and adolescents. Moreover, further investigation of the benefits observed with some nutrient supplements (such as omega-3 and vitamin D for ADHD) through larger-scale RCTs is imperative to establish more robust conclusions.

We investigated the link between nutrition and mental health in children and adolescents through a meta-review of 24 relevant meta-analyses. Emerging evidence suggests potential benefits of Omega-3 and Vitamin D in treating ADHD, while no evidence supports their effectiveness in ASD. Observational data also indicate that prenatal folic acid supplementation may lower ASD risk. Healthy dietary patterns reduce the risk of internalizing and externalizing disorders, whereas unhealthy habits elevate the risk. Limited studies on dietary interventions for depression, ASD, and ADHD provide inconclusive results. In summary, our results emphasize the need to clearly understand the cause-and-effect relationships between dietary habits and mental health risks in young individuals. Larger-scale randomized controlled trials are essential for confirming the observed benefits of nutrient supplements such as omega-3 and vitamin D in treating ADHD and for forming more reliable conclusions.

Dimensional model on how familial vulnerability and environmental factors impact transitional age youth psychopathology: The Transition_psy study.

Background: Understanding psychopathology in transitional age youth (TAY) requires a complex model, incorporating familial vulnerability and environmental factors. A trans-diagnostic and dimensional approach seems the most appropriate. Transition_psy study aims to assess factors playing a role in TAY psychopathology and to define predictors. Materials and methods: This article presents part of the Transition_psy study results, a case-control observational study. Youth aged 17 years old were recruited between June 2020 and December 2021, from both clinical [clinical population (CP) group] and non-clinical settings [non-clinical population (NCP) group]. Participants completed self-report questionnaires. The primary outcome to assess TAY psychopathology was the Youth-Self Report (YSR). We evaluated care needs with the Health of The Nation Outcome Scales For Children And Adolescents (HoNOSCA-SR) and quality of life with the World Health Organization Quality of Life - BREF (WHOQoL-BREF). Exposure factors included familial vulnerability, childhood, and present environmental factors, such as first-degree family history of psychopathology, the Childhood Trauma Questionnaire (CTQ) and the Family Assessment Device (FAD). YSR scores were compared, between groups, according to exposure factors with ANOVA and linear regression. We performed best subsets selection of multivariable analyses based on the Akaike Information Criterion. This study was registered with ClinicalTrials.gov (Identifier: NCT04333797). Results: A total of 220 TAY (CP = 106, NCP = 114) were included in the study. Participants were aged 17 years old. The majority were female (69.1%), single (96.8%), and born in Belgium (82.3%). Clinical data were all significantly different between CP and NCP groups. YSR scores were found statistically different according to group (p < 0.001), first-degree family history of psychopathology (p < 0.001), CTQ (p < 0.001), and FAD (p < 0.001). Predictive dimensional model suggested that TAY psychopathology can be predicted by group, CTQ and FAD. Significant positive correlation was found between YSR and HoNOSCA (rho = 0.81) and negative correlation between YSR and physical and psychological health (rho = -0.69 and -0.71, respectively). Conclusion: This study findings allowed to present a predictive dimensional model on TAY psychopathology, including belonging to a clinical population at transitional age, childhood trauma, and family dysfunction. Further research is needed to replicate Transition_psy study results in other samples. The proposed model could be used in clinical practice to improve assessment of TAY psychopathology.

Case report: From anxiety disorders to psychosis, a continuum in transitional age youth?

Introduction: To date, among individuals meeting ultra-high risk criteria for psychosis, the relationship between the presence of anxiety disorders and the risk of psychotic transition raises several unanswered questions. Case description: This case report describes the clinical progression of a 17-year-old male initially presenting anxious symptoms meeting the DSM-V criteria for panic disorder. The patient also reported social withdraw, mild depressive symptoms, insomnia and fatigue. Over a 6 month period, a gradual onset of subthreshold psychotic symptoms suggested a prodromal phase of a psychotic disorder. Diagnostic assessment and therapeutic intervention: A detailed assessment of UHR criteria for psychosis was performed. The overall level of social and occupational functioning was assessed by the SOFAS, which showed a 35% drop over a 12 months period. The CAARMS, has also been administered. The patient met the diagnostic criteria for UHR, APS group. The care plan included psychiatric follow-up, pharmacologic treatment, individual psychological follow-up and individual and familial psychoeducation. Over a 6 months period, the patient did not experienced a first psychotic episode and presented a partial improvement of psychotic symptoms. Conclusion: The DSM-V categorical approach does not seem to adapt well to early clinical presentations in transitional age youth. A transdiagnostic and dimensional approach allows to better identify at-risk patients of psychiatric disorders and implement early intervention strategies.

Study Protocol: Transition_psy a Multicenter Prospective Longitudinal Cohort Study Assessing Risk and Protective Factors to Develop Psychopathology in Transitional Age Youth in Belgium.

Introduction: Emerging adults are a particularly at-risk population in mental health. The primary aim of the Transition_psy study is to evaluate changes in mental health care need and quality of life during transition from Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS). The relationship between these changes and genetic or environmental vulnerabilities and clinical dimensions representing risk and protective factors to the development of psychopathology will be analyzed. We also aim to explore how each factor plays, specifically, a role in developing internalizing and externalizing symptoms, in order to predict the most common paths of psychopathology in transitional age youth (TAY). Methods and Analysis: Transition_psy is a multicenter prospective longitudinal cohort study. The transversal and trans-diagnostic approach consists of a dimensional evaluation: 300 youth at the age of 17 will be included in a cohort of in-patients, out-patients and control group. Participants will be assessed at baseline (T0) and 24 months later (T1). The primary objective to determine changes in self-rated Health Of The Nation Outcome Scales For Children And Adolescents (HONOSCA-SR) and WHO Quality of Life-BREF (WHOQOL-BREF) scores between T0 and T1. Pearson correlation and mediation analysis will be performed. A secondary objective analysis using mediation and moderation models with several dimensional aspects, including self-reported and cognitive measures, will be conducted to disentangle the potential relationships between the two scores. Discussion: Transition from CAMHS to AMHS occurs at a crucial age in terms of the continuum between adolescent and adulthood psychopathology. This collaborative and cohesive protocol between CAMHS and AMHS represents the first national cohort study about Transition Psychiatry in French-speaking Belgium. Ethics and Dissemination: The study protocol was approved by the Institutional Review Boards (IRB) of the three participating sites. Results will be published in peer-reviewed journals and disseminated at national and international conferences. This trial was registered in ClinicalTrials.gov (Identifier: NCT04333797) on 3 April 2020.

What Happens Next? Current Knowledge and Clinical Perspective of Pregnancy Denial and Children's Outcome.

INTRODUCTION: Denial of Pregnancy is a women's subjective lack of awareness of being pregnant. It can be partial (from 20 weeks but lifted before delivery) or complete (the women notice she's pregnant when labour starts). The prevalence is around 1/500 for partial denial and 1/2500 for complete denial. This article's aim is to review the literature broadly on the subject of pregnancy denial, its psychopathological hypothesis and the state of knowledge on the outcome for mothers and children. METHODS: 26 references have been selected bases on a research on pubmed database and through bibliography on the selected papers. RESULTS: Despite a lot of psychopathological hypothesis and some epidemiological studies, no objective knowledge can lead to know what kind of women will deny their pregnancy and how to prevent it. After all the studies on mother characteristics, it seems there are no "clear-cut" explanations on why a woman denies a pregnancy or what type of women could be at risk of denial. There are no official guidelines on how to manage the condition and care for the patient long term. The first elements of research on the developmental outcome for infant seem to show a delay in psychomotor skills and possible speech disorder. They have been significant advancement on the subject of children development after pregnancy denial in the last year but the psychological and developmental impact of pregnancy denial on children and mothers is still majorly unknown. With a clinical picture known for so long, to have so little objective information on how to manage it and on the possible consequences is surprising. CONCLUSION: More research needs to be conducted to objectively know the long term effects of pregnancy denial on the whole family. International consensus should be found on the definition and care management of pregnancy denial.

Nonlinear dynamics of runaways among children and adolescents: disruptive disorder or step toward a suicide attempt?

The aim of this study is to analyze the decision-making process whereby susceptible adolescents end up choosing the option to run away or attempt suicide. Our basic hypothesis is that this transition is largely based on cooperative mechanisms. The runaway state is regarded as a potential precursor of the suicidal one. A mathematical model incorporating these processes is developed from which the time evolution and the values of the susceptible, runaway and suicidal populations are evaluated in terms of a number of key parameters. It is shown that for appropriate ranges of parameter values the interactions present in the system eventually end up counteracting both runaway and suicidal attempts. Quantitatively this is shown by the existence of stable solutions of the model equations in which the populations of both suicidal and runaway individuals end up being zero, although in some cases a significant temporary enhancement can take place. But as the parameters are varied beyond these ranges the system starts sustaining non-trivial stable states, in which the populations of suicidals or runaways are maintained at non-zero levels. This hints at prevention strategies and crisis management such as separation from the environment and specific treatment different from those dispending traditional adolescent psychiatric units.
