This is a naturalistic treatment and follow-up study of youth with bipolar spectrum disorders (BSDs) across four US sites of The Childhood Bipolar Network (CBN). CBN sites have expertise in diagnosing, assessing, and treating BSDs in youth. The primary aims of this study are to (1) identify and reliably diagnose youth (ages 9 to 19 yrs) with full bipolar disorder (BD) and BSDs, and (2) examine predictors (e.g., mood instability, inflammatory marker C-reactive protein) of clinical outcome over a 12 month period. Participating youth will initially complete a screening that includes a structured diagnostic interview and a baseline blood draw to measure inflammatory processes. Youth with BSD and parents (80 families) will be asked to participate in multiple follow up research visits with interviews, rating instruments, and questionnaires. Per established CBN guidelines, study psychiatrists will provide and track medication management and sites will also track psychosocial treatments. This study ultimately aims to further understanding of best practice pediatric BSD psychiatric and psychosocial treatments and development of a standardized and validated set of clinical tools for patient assessment, diagnosis, and tracking.

There are few treatment options available for patients once they have failed standard psychopharmacological therapy for generalized anxiety disorder. Existing brain stimulation methods such as rTMS fail to target deep brain structures associated with anxiety disorders; structures such as the amygdala. In this double-blind sham-controlled clinical trial, the investigators propose to establish baseline severity of anxiety in 48 patients, then deliver eight treatments over four sessions of focused ultrasound stimulation to the amygdala. Anxiety severity will be assessed using standard psychometric scales after each session, and at follow-ups.

Emotional dysregulation in justice-involved youth (JIY) is a condition that significantly impacts young people, their families, and juvenile justice and public health systems. Affecting an estimated 60-70% of detained Attention deficit hyperactivity disorderadolescents, it is a major driver of aggression, substance use, school failure, and later recidivism. Despite available treatments, managing emotional dysregulation in custody remains challenging, with youth often enduring high arousal, anger, and anxiety that persist into adulthood. Current popular therapies, including Cognitive Behavioral Therapy (CBT) and Dialectic Behavioral Therapy (DBT), often fall short in detention because they rely on verbal processing, require multiple scheduled sessions, and/or need highly trained staff. Other technologies, like biofeedback and neurostimulation techniques, are still under scrutiny for adolescents, given their higher-than-usual Adverse Events (AEs). This SoundHeal study aims to evaluate a sensory intervention using the Healpod, a distraction-free physical space where a participant sits, delivering sound, music, gentle vibrations, and ambient light. Following this is a brief expressive journaling exercise to compare any before, during and after experience changes from the sensory immersion. This prospective, single-center cohort study hypothesizes that these sessions will improve juveniles' ability to emotionally regulate, improve therapeutic alliance, mental health outcomes and build coping skills that can potentially help in long-term mental health and substance abuse treatment in JIY and beyond.

Investigators will conduct a confirmatory efficacy trial of Interpersonal and Social Rhythm Therapy (IPSRT) delivered via telehealth for offspring of bipolar parents (OBP; age 12-18, n=120) at elevated risk for BP onset via risk calculator score. All participants receive a baseline clinical assessment of psychiatric symptoms and sleep disturbance (via objective and subjective methods), followed by a feedback session. Youth are then randomized to receive 8 sessions of IPSRT or a manualized Healthy Lifestyle Behaviors Program (HL) delivered via secure videoconference. As clinically indicated, youth are offered Community Treatment Referral (CTR) for any psychiatric symptoms/disorders identified at intake. Primary outcome domains over 18 months include mania and affective lability. Investigators will also further investigate the hypothesized mechanism underlying IPSRT (i.e., sleep/circadian disruption) across levels of analysis, and the contribution of interpersonal stress to sleep/circadian disruptions. Application of Implementation Science methods throughout maximizes ultimate scalability and feasibility if efficacious. Investigators will also examine whether passive cellphone sensing may serve as a portable, cost-effective measure of mechanisms and outcomes to enhance ultimate dissemination.
