Differing impact of the COVID-19 pandemic on youth mental health: combined population and clinical study.

BACKGROUND: Identifying youths most at risk to COVID-19-related mental illness is essential for the development of effective targeted interventions. AIMS: To compare trajectories of mental health throughout the pandemic in youth with and without prior mental illness and identify those most at risk of COVID-19-related mental illness. METHOD: Data were collected from individuals aged 18-26 years (N = 669) from two existing cohorts: IMAGEN, a population-based cohort; and ESTRA/STRATIFY, clinical cohorts of individuals with pre-existing diagnoses of mental disorders. Repeated COVID-19 surveys and standardised mental health assessments were used to compare trajectories of mental health symptoms from before the pandemic through to the second lockdown. RESULTS: Mental health trajectories differed significantly between cohorts. In the population cohort, depression and eating disorder symptoms increased by 33.9% (95% CI 31.78-36.57) and 15.6% (95% CI 15.39-15.68) during the pandemic, respectively. By contrast, these remained high over time in the clinical cohort. Conversely, trajectories of alcohol misuse were similar in both cohorts, decreasing continuously (a 15.2% decrease) during the pandemic. Pre-pandemic symptom severity predicted the observed mental health trajectories in the population cohort. Surprisingly, being relatively healthy predicted increases in depression and eating disorder symptoms and in body mass index. By contrast, those initially at higher risk for depression or eating disorders reported a lasting decrease. CONCLUSIONS: Healthier young people may be at greater risk of developing depressive or eating disorder symptoms during the COVID-19 pandemic. Targeted mental health interventions considering prior diagnostic risk may be warranted to help young people cope with the challenges of psychosocial stress and reduce the associated healthcare burden.

A shared neural basis underlying psychiatric comorbidity.

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 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.

Chronotype, Longitudinal Volumetric Brain Variations Throughout Adolescence, and Depressive Symptom Development.

OBJECTIVE: Adolescence is a critical period for circadian rhythm, with a strong shift toward eveningness around age 14. Also, eveningness in adolescence has been found to predict later onset of depressive symptoms. However, no previous study has investigated structural variations associated with chronotype in early adolescence and how this adds to the development of depressive symptoms. METHOD: Assessment of 128 community-based adolescents (51% girls) at age 14 and 19 years was performed. Using whole-brain voxel-based morphometry, baseline (at age 14) regional gray matter volumes (GMVs), follow-up (at age 19) regional GMVs, and longitudinal changes (between 14 and 19) associated with Morningness/Eveningness Scale in Children score and sleep habits at baseline were measured. The association of GMV with depressive symptoms at 19 years was studied, and the role of potential clinical and genetic factors as mediators and moderators was assessed. RESULTS: Higher eveningness was associated with larger GMV in the right medial prefrontal cortex at ages 14 and 19 in the whole sample. GMV in this region related to depressive symptoms at age 19 in catechol-O-methyltransferase (COMT) Val/Val, but not in Met COMT, carriers. Larger GMV also was observed in the right fusiform gyrus at age 14, which was explained by later wake-up time during weekends. CONCLUSION: In adolescence, eveningness and its related sleep habits correlated with distinct developmental patterns. Eveningness was specifically associated with GMV changes in the medial prefrontal cortex; this could serve as a brain vulnerability factor for later self-reported depressive symptoms in COMT Val/Val carriers.

Internet-Based Prevention Program of Victimization for Youth in Care and Care Leavers (EMPOWER YOUTH): Protocol for a Randomized Controlled Trial.

BACKGROUND: The global estimate of the number of children in institutional care is around 5 million, with around 1 million of these children living in Europe. In Germany, about 75,000 children and adolescents find themselves in the foster care system and about 93,000 additional children and adolescents are living in institutions. Traumatic experiences and neglect in childhood are highly prevalent among these youth in care and are related to severe long-term effects. Childhood maltreatment and abuse can increase the risk of future victimization experiences. Although youth in care are at risk of victimization or revictimization, no specific evidence-based prevention program has been designed to address these specific needs. OBJECTIVE: This study aims to evaluate the efficacy of a newly developed 6-module internet-based prevention program of victimization for youth in care, named EMPOWER YOUTH. METHODS: In a randomized controlled trial, the intervention group will be compared to a waiting-list control group with an unblinded 1:1 allocation ratio. Assessments will take place before randomization (baseline) and at follow-up 18 weeks after baseline (ie, 12 weeks after finishing the last module of the program). The primary endpoint is the number of victimization, and online and offline bullying experiences (composite score) at the 18-week follow-up. Secondary endpoints are risk-taking behavior, aggressive tendencies, empathy, prosocial behavior, depressiveness, and loneliness at follow-up. The expected outcome requires a sample size of 156 subjects to achieve a power of 80%. Assuming a 30% dropout rate at follow-up, we require 225 participants to be allocated to the trial. Participants are youth in care, that is, adolescents in foster care, adopted adolescents, or young care leavers aged 14 to 21 years. RESULTS: Ethical approval was granted by the Ethics Committee of the Medical School Berlin in March 2021 (MSB-2021/55). Recruitment started in September 2021 and is planned until November 2022. The results are expected to be published in January 2023. CONCLUSIONS: Given the increased likelihood for future victimization experiences among youth in care, there is a strong need for a low-threshold intervention specifically for this high-risk age group. There are no existing nationwide mental health programs exclusively for youth in care in Germany. TRIAL REGISTRATION: German Clinical Trials Register DRKS00024749; https://tinyurl.com/tjaahayw.

Executive functioning in adolescent anorexia nervosa: Neuropsychology versus self- and parental-report.

There is limited research concerning the relationship between neuropsychological assessment and self-report of executive functioning in adolescent anorexia nervosa (AN); available studies demonstrate only low to moderate correlations. Therefore, this study examines the association between neuropsychological test performance and self-report in AN. Forty adolescent inpatients with AN completed an extensive neuropsychological assessment, including set-shifting, central coherence, and questionnaires assessing executive functioning in daily life (BRIEF-SR). Their parents filled out an analog version (BRIEF-PF). Statistical analyses revealed low to medium positive and negative correlations between neuropsychological measures and BRIEF subscales. Similarly, self- and parental ratings were only slightly positively correlated, with patients scoring significantly higher than their parents on two subscales. The results support previous findings of modest correlations between self-report and performance-based testing and emphasize the importance of a multiple format assessment of executive functioning in adolescent AN.

A multicentre randomized controlled trial on trans-generational attention deficit/hyperactivity disorder (ADHD) in mothers and children (AIMAC): an exploratory analysis of predictors and moderators of treatment outcome.

OBJECTIVE: We examined predictors and moderators of treatment outcome in mothers and children diagnosed with ADHD in a large multicentre RCT. METHOD: In total, 144 mother-child dyads with ADHD were randomly assigned to either a maternal ADHD treatment (group psychotherapy and open methylphenidate medication, TG) or to a control treatment (individual counselling without psycho- or pharmacotherapy, CG). After maternal ADHD treatment, parent-child training (PCT) for all mother-child dyads was added. The final analysis set was based on 123 dyads with completed primary outcome assessments (TG: n = 67, CG: n = 56). The primary outcome was the change in each child's externalizing symptoms. Multiple linear regression analyses were performed. RESULTS: The severity of the child's externalizing problem behaviour in the family at baseline predicted more externalizing symptoms in the child after PCT, independent of maternal treatment. When mothers had a comorbid depression, TG children showed more externalizing symptoms after PCT than CG children of depressive mothers. No differences between the treatment arms were seen in the mothers without comorbid depression. CONCLUSIONS: Severely impaired mothers with ADHD and depressive disorder are likely to need additional disorder-specific treatment for their comorbid psychiatric disorders to effectively transfer the contents of the PCT to the home situation (CCTISRCTN73911400).

Clinical characteristics of early onset anorexia nervosa.

The aim of the current paper is to evaluate clinical characteristics of 30 children with early onset anorexia nervosa (EO-AN; age = 12.2 ± 1.6 years) compared with 30 patients with adolescent onset AN (AO-AN; age = 15.9 ± 0.7 years) and 60 age-matched healthy controls. Statistical analyses included one-way analyses of variance with three planned comparisons and chi-square tests. Compared with AO-AN, EO-AN patients displayed more restrictive eating behaviour (p = 0.038), received more tube-feeding (p = 0.024), and had less problems with self-esteem (p < 0.001) and perfectionism (p = 0.001). EO-AN patients have similar eating disorder pathology (p = 0.183), body-image distortion (p = 0.060), and number of hospitalizations (p = 0.358) as AO-AN. Only a third of EO-AN patients suffer from low self-esteem. Overall, core AN pathology seems similar in EO-AN and AO-AN. However, EO-AN patients show differences in their pathological eating behaviour and the need for tube-feeding.

Differences in set-shifting and central coherence across anorexia nervosa subtypes in children and adolescents.

OBJECTIVE: Regarding executive functioning in anorexia nervosa (AN), little is known about differences between the restricting (AN-R) and binge eating/purging (AN-BP) subtypes. Especially for adolescents, there is sparse data. Hence, the current aim is to investigate differences in set-shifting, central coherence, and self-reported executive functioning across adolescent AN subtypes. METHODS: Ninety AN-R, 21 AN-BP, and 63 controls completed an extensive assessment battery including neuropsychological tests for executive functioning and the self-report questionnaire Behavior Rating Inventory of Executive Functioning. RESULTS: Patients with AN-R and AN-BP did not differ on neuropsychological measures, and both performed similarly to controls. Behavior Rating Inventory of Executive Functioning scores fell within the normal range with AN subtypes showing mostly comparable ratings. AN-BP patients scored higher on 2 composite indices and the "shift" subscale compared with AN-R. CONCLUSIONS: The results suggest similar cognitive functioning in adolescent AN subtypes as well as healthy controls. However, more research is needed to draw more general conclusions.

Cognitive Flexibility in Juvenile Anorexia Nervosain Relation to Comorbid Symptoms of Depression, Obsessive Compulsive Symptoms and Duration of Illness.

OBJECTIVE: Whereas the evidence in adolescents is inconsistent, anorexia nervosa (AN) in adults is characterized by weak cognitive flexibility. This study investigates cognitive flexibility in adolescents with AN and its potential associations with symptoms of depression, obsessive compulsive disorder (OCD), and duration of illness. METHODS: 69 patients and 63 age-matched healthy controls (HC) from 9 till 19 years of age were assessed using the Trail-Making Test (TMT) and self-report questionnaires. RESULTS: In hierarchical regression analyses, set-shifting ability did not differ between AN and HC, whereas AN patients reported significantly higher rates of depression symptoms and OCD symptoms. Age significantly predicted set-shifting in the total sample. Only among AN patients aged 14 years and older did set-shifting decline with increasing age. DISCUSSION: The presence of AN with depression or OCD symptoms or the duration of illness do not influence cognitive flexibility in children and adolescents. Early interventions may be helpful to prevent a decline in cognitive flexibility in adolescent AN with increasing age.

Similarities and Differences of Neuropsychological Profiles in Children and Adolescents with Anorexia Nervosa and Healthy Controls Using Cluster and Discriminant Function Analyses.

OBJECTIVE: This study aimed to identify discrete neuropsychological profiles and their relationship to clinical symptoms in 253 female children and adolescents with anorexia nervosa (AN) and 170 healthy controls (HCs) using a standardised neuropsychological assessment battery. METHOD: Hierarchical cluster analysis was used to identify the optimum number of clusters, and participants were assigned using K-means cluster analysis. Confirmatory discriminant function analysis determined which combination of neuropsychological variables best distinguished the clusters. RESULTS: Three distinct clusters in the AN sample emerged- AN cluster 1 (19%) - "neuropsychologically low average to average"; AN cluster 2 (33%) - "verbal/visuo-spatial discrepancy"; and AN cluster 3 (48%) - "verbally strong and neuropsychologically average to high average". Two distinct clusters in HCs were identified. HC cluster 1 (48%) demonstrated poor visuo-spatial memory scores and high verbal fluency scores, whilst HC cluster 2 (52%) scored within the average range on all neuropsychological tasks. Neuropsychological performance was associated with clinical symptoms of body mass index centile, Eating Disorder Examination subscale and global score, anxiety, depression and obsessions, and compulsions between the AN and HC groups. However, niether significant differences emerged between AN clusters only nor HC clusters only at the post-hoc level. DISCUSSION: An underlying neuropsychological heterogeneity may exist in AN. We encourage future studies to investigate whether the identified profiles and their association with clinical characteristics are replicable. We cautiously suggest that neuropsychological profiling may have potential to both inform future research and have possible clinical benefits through individually tailored treatment strategies.

[Feedback on Cognitive Remediation Therapy from Adolescents with Anorexia Nervosa - A Qualitative Study]. / Therapiewahrnehmung der 'Cognitive Remediation Therapy' bei Jugendlichen mit Anorexia nervosa - Eine qualitative Analyse.

BACKGROUND: Cognitive remediation therapy (CRT) is a relatively new therapy for patients with anorexia nervosa (AN). There is an increased demand to include the patient view during the evaluation of treatment programs. So far, there is no structured evaluation of the subjective view of adolescents with AN on CRT available. METHODS: 20 patients with AN between the ages of 12 and 18 years completed 10 CRT sessions. 19 patients (age: 15.6±1.3; BMI-percentile: 2.4±3.5) filled out a feedback questionnaire on their subjective CRT experience. The positive and negative aspects of CRT from a patient's perspective were inducted from the feedback material using the 'Qualitative content analysis' from Mayring, allowing the data to be summarized into different categories. The software program MAXQDA 11 was used for the data analysis. RESULTS: The final category system consisted of 6 general categories, which in turn were summarized into 4 main categories: "general therapy perception", "content specific therapy perception", "relationship to everyday life" and "relationship with CRT therapist". 10 patients described CRT (53%) as 'fun'. 12 patients (63%) noticed positive changes in their everyday lives, which they attributed to their participation in CRT. 4 patients (21%) were not able to notice any changes in their everyday lives. 3 patients (16%) valued the good atmosphere during the CRT sessions and 6 patients (32%) found CRT to be a welcome distraction from their daily lives on the ward. 5 patients (26%) mentioned that CRT was too demanding and that difficulties arose during their reflection on thinking styles. DISCUSSION: Overall, CRT is evaluated positively by adolescent patients with AN. A small number of patients reports difficulties with CRT and experiences CRT as strenuous. This positive evaluation of CRT is in line with results from the few qualitative studies in adults with AN. Due to a potential social desirability bias, the patient's perspective should be interpreted with slight caution. CONCLUSION: CRT is received well by adolescents with AN and poses an interesting, new therapy module in the eating disorder field.

Cognitive performance in children with acute early-onset anorexia nervosa.

When anorexia nervosa (AN) occurs in children below the age of 14 years, it is referred to as early-onset AN (EO-AN). Over the last years, there has been an increased focus on the role of cognitive functioning in the development and maintenance of AN. Adults with AN show inefficiencies in cognitive functions such as flexibility and central coherence. Systematic neuropsychological examinations of patients with EO-AN are missing. Thirty children with EO-AN and 30 adolescents with AN, as well as 60 healthy controls (HC) underwent an extensive neuropsychological examination. ANOVAs with post hoc tests and explorative regression analyses were conducted. Patients with EO-AN (mean age = 2.17 ± 1.57 years) showed no significant differences in flexibility, inhibition, planning, central coherence, visuospatial short- and long-term memory or recognition in comparison to HC (mean age = 11.62 ± 1.29 years). Performance of adolescents with AN (mean age = 15.93 ± 0.70 years) was not significantly different compared to HC (mean age = 16.20 ± 1.26 years). Explorative regression analyses revealed a significant interaction of age and group for flexibility (adjusted R 2  = 0.30, F = 17.85, p = 0.013, η p2  = 0.32). Contrary to expectations, the current study could not confirm the presence of inefficient cognitive processing in children with EO-AN compared to HC. Nonetheless, the expected age-related improvement of flexibility might be disrupted in children and adolescents with AN. Longitudinal neuropsychological examinations are necessary to provide more information about the role of cognitive functioning in the development and maintenance of AN.

Neuropsychological and Behavioural Short-Term Effects of Cognitive Remediation Therapy in Adolescent Anorexia Nervosa: A Pilot Study.

OBJECTIVE: Cognitive remediation therapy (CRT) aims to strengthen weak cognitive flexibility and central coherence in adult and adolescent anorexia nervosa (AN). Currently, there are no studies in adolescents with AN that control for learning effects because of re-testing while evaluating CRT. METHOD: Twenty in- and outpatients with AN aged 12 to 18 years received CRT. Assessment took place directly before and after the intervention. Performance was compared to 20 age-, gender-, IQ-, and test-retest interval matched healthy controls, which did not receive CRT. RESULTS: AN patients showed an improvement in flexibility on neuropsychological assessment directly after CRT, whereas HC did not improve over time. Self-report assessment of flexibility, as well as central coherence, did not show significant improvement after CRT. DISCUSSION: Results suggest that CRT may be beneficial for enhancing flexibility in adolescents with AN. However, randomized controlled studies are essential to determine the actual efficacy of this intervention.

Cognitive Remediation Therapy for Children with Anorexia Nervosa.

OBJECTIVE: Evidence-based treatment programs for children with anorexia nervosa (AN) are scarce, while their prognosis is negative and the incidence rate rises. A new therapeutic approach recently received positive attention: cognitive remediation therapy (CRT). This intervention targets inflexibility and the inability to perceive the bigger picture in persons with AN. So far, studies and case reports have focused on either adolescent or adult patients and less on young children with AN. This case report therefore describes and evaluates the implementation of CRT with a child with AN. METHOD: A 12-year-old girl with severe chronic AN was treated with 10 sessions of CRT. Her clinical and neuropsychological evaluations before, directly after and 7 months after CRT are reported. Additionally, the patient's written and verbal feedbacks are reviewed. RESULTS: At the 7-month follow-up the patient showed a stable healthy weight and reported a reduced presence of psychopathology. Her neuropsychological performance directly after CRT and after 7 months did not improve. CONCLUSIONS: The clinical evaluation of our case report suggests that CRT may be a promising add-on therapy in the clinical treatment of young girls with AN.

Anti-NMDA receptor encephalitis presenting as atypical anorexia nervosa: an adolescent case report.

Since 2007, more than 600 patients have been diagnosed with anti-N-methyl-D-aspartate (NMDA) receptor encephalitis, with almost 40 % of those affected being children or adolescents. In early phases of the illness, this life-threatening disease is characterized by psychiatric symptoms, such as depression, anxiety, obsessions, hallucinations or delusions. Consequently, a high percentage of patients receive psychiatric diagnoses at first, hindering the crucial early diagnosis and treatment of the anti-NMDA receptor encephalitis. We report on a 15-year-old girl initially presenting with pathological eating behaviour and significant weight loss resulting in an (atypical) anorexia nervosa (AN) diagnosis. Her early course of illness, diagnostic process, treatment and short-term outcome are described. This case report aims to raise awareness about the association between anorectic behaviour and anti-NMDA receptor encephalitis and highlight the importance of multidisciplinary teams in child and adolescent services.

[An international neuropsychological assessment tool for children, adolescents, and adults with anorexia nervosa ­ the German adaptation of the Ravello Profile]. / Eine internationale neuropsychologische Testbatterie für Kinder, Jugendliche und Erwachsene mit Anorexia nervosa - die deutsche Adaptation des Ravello Profils

OBJECTIVE: Adults with anorexia nervosa (AN) show weaknesses in several cognitive functions before and after weight restoration. There is a great demand for standardized examinations of executive functioning in the field of child and adolescent AN. Previous studies exhibited methodological inconsistencies regarding test selection and operationalization of cognitive functions, making the interpretation of their findings difficult. In order to overcome these inconsistencies, a neuropsychological assessment tool, the "Ravello Profile," was developed, though previously not available in German. This paper presents a German adaptation of the Ravello Profile and illustrates its applicability in children and adolescents via three case descriptions. METHODS: The Ravello Profile was adapted for the German-speaking area. The applicability of the Ravello Profile was evaluated in three children and adolescents with AN. RESULTS AND CONCLUSIONS: The cases presented confirm the feasible implementation of this adaptation of the Ravello Profile, both in children and adolescents. Hence, it enables a methodologically consistent examination of executive functioning in German-speaking children, adolescents, and adults with AN. Using the Ravello Profile, the role of cognitive functions in the development of AN can be systematically examined over a broad age range.
