Multimodal phenotyping in adolescents hospitalized for depression

Digital Phenotyping and Multimodal Biomarker Discovery for Major Depressive Episodes in Adolescent Inpatients: A Prospective Cohort Study

Observational Jiangsu Province Nanjing Brain Hospital · NCT07247344

This project will collect brain scans, blood tests, sleep and activity signals, and psychological test results from hospitalized teens with major depressive episodes to try to find patterns that predict treatment response and cognitive or emotional problems.

What this trial studies

This is a longitudinal observational cohort of adolescents aged 10–20 hospitalized for moderate to severe major depressive episodes (including MDD and bipolar disorder) that will collect serial clinical, serum biomarker, physiological-behavioral, neuropsychological, and neuroimaging data. Participants will undergo repeated assessments and follow-up to capture dynamic changes in mood, cognition, behavior, and biological signals during treatment. The study aims to summarize clinical and neuroimaging phenotypes, identify novel risk factors, and link clinical manifestations with brain features. Multivariate predictive models integrating the various data types will be developed to predict treatment response and cognitive-emotional outcomes.

Who should consider this trial

Good fit: Adolescents aged 10–20 hospitalized with a current moderate to severe major depressive episode (HAMD ≥17) diagnosed as MDD or bipolar disorder and able to provide informed consent (with parental consent for those under 18).

Not a fit: Patients who do not have a current moderate–severe depressive episode, are treated recently with certain brain stimulation or standard psychotherapy within 6 months, or who are not hospitalized or unable to complete imaging and biomarker procedures are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the work could help clinicians predict which adolescents are likely to respond to treatment and tailor care based on combined clinical, biological, and imaging markers.

How similar studies have performed: Multimodal biomarker and predictive-model studies in adult depression have shown promising signals, but comparable longitudinal multimodal work specifically in adolescent inpatient populations is limited.
