Objective: Research and clinical application of transcranial magnetic stimulation (TMS) for adolescents with major depressive disorder (MDD) has advanced slowly. Significant gaps persist in our understanding of optimized, age-specific protocols and dosing strategies. This study aimed to compare the clinical effects of 1 Hz versus 10 Hz TMS regimens and examine a biomarker-informed treatment approach with glutamatergic intracortical facilitation (ICF).

Method: Participants with moderate-to-severe symptoms of MDD were randomized to 30 sessions of left prefrontal 1 Hz or 10 Hz TMS, stratified by baseline ICF measures. The primary clinical outcome measure was the Children's Depression Rating Scale, Revised (CDRS-R). The CDRS-R and ICF biomarker were collected weekly.

Results: Forty-one participants received either 1 Hz (n = 22) or 10 Hz (n = 19) TMS treatments. CDRS-R scores improved compared to baseline in both 1 Hz and 10 Hz groups. For participants with low ICF at baseline, the overall least squares means of CDRS-R scores over the 6-week trial showed that depressive symptom severity was lower for the group treated with 1 Hz TMS than for those who received 10 Hz TMS. There were no significant changes in weekly ICF measurements across the 6 weeks of TMS treatment.

Conclusion: Low ICF may reflect optimal glutamatergic N-methyl-d-aspartate (NMDA) receptor activity that facilitates the therapeutic effect of 1 Hz TMS through long-term depression-like mechanisms on synaptic plasticity. The stability of ICF suggests that it is a tonic, trait-like measure of NMDA receptor-mediated neurotransmission, with potential utility to inform parameter selection for therapeutic TMS in adolescents with MDD.

Objective: This observational study compared children with and without binge eating (BE) on biobehavioral measures of reward responsiveness, inhibitory control, and emotion processes, while accounting for the impact of weight.

Method: Children aged 9-10 completed the baseline wave of the Adolescent Brain Cognitive Development study (316 with BE; 7,681 without BE [no-BE]). The prevalence of binge-eating disorder in the BE group was 17.0%; clinically significant internalizing and externalizing symptoms were endorsed by 8.5% and 4.5% of the sample, respectively. The monetary incentive delay (MID) task, stop signal task (SST), and emotional N-back (EN-back) task were administered during neuroimaging. Analyses assessed effects of group (BE vs. no-BE) on task performance and corresponding neural signal in regions of interest (ROIs). Weight status was evaluated as a covariate and as a moderator of effects.

Results: Adjusting for weight status, the BE group (vs. no-BE) group showed lower activation during anticipation of reward, specifically large reward (vs. no reward), in the composite ROI consisting of the dorsal striatum, nucleus accumbens, orbital frontal gyrus, amygdala and insula. Groups did not differ significantly in other behavioral or neural outcomes. No interactions between group and weight status were observed.

Conclusion: Blunted anticipatory responses to monetary reward were associated with binge eating during peri-adolescence and may play a role in binge eating pathophysiology. Results challenge prior findings in BE that may be confounded by weight, as well as highlight the importance of future prospective research across binge-eating disorder stage of illness.

Objective: To examine recent trends in clinical diagnoses of children and adolescents receiving treatment in publicly funded mental health treatment services in the United States.

Method: Data on children and adolescents (≤17 years) receiving treatment from publicly funded mental health treatment services recorded in Mental Health Client Level Data (MH-CLD) 2013-2021 (total number of records=13,684,154) were used to examine temporal trends in the proportion of different child and adolescent psychiatric disorders. Trends were examined overall and in age, sex, racial/ethnic and service strata focusing on community-based programs.

Results: The analyses revealed increases in the proportion with anxiety disorders from 9.6% in 2013 to 19.2% in 2021, AOR=2.17, 95% CI=1.85-2.55, p<0.001, trauma- and stressor-related disorders from 22.7% to 27.4%, AOR=1.31, 1.09-1.57, p=0.004, and depressive disorders from 13.4% to 17.0%, AOR=1.20, 1.03-1.41, p=0.04. During this same period, the proportion with bipolar disorders declined almost eight-fold from 10.0% to 1.3%; AOR=0.07, 0.06-0.09, p<0.001. The proportion with conduct disorders also declined from 9.7% to 4.4%; AOR=0.42, 0.32-0.55, p<0.001, and the proportion of oppositional-defiant disorder declined from 11.1% to 7.8%; AOR=0.79, 0.65-0.98, p=0.03. Trends varied across sex, age, and racial/ethnic strata.

Conclusion: The composition of childhood psychiatric diagnoses in patients within publicly funded mental health settings changed over the past decade. While some of the trends may reflect changes in diagnostic practices of clinicians, increases in anxiety and depressive disorders parallel trends in the prevalence of these conditions in the general population and highlight a growing need for identifying and treating these conditions in this age group.
