Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07246044). This is a study registration, not published results. Lead sponsor: Jiangsu Province Nanjing Brain Hospital. Recruitment status: RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 100 participants (ESTIMATED). Conditions: Adolescent, Bipolar Depression, tDCS, Primary Somatosensory Cortex, Bipolar Disorder Depression. Interventions: DEVICE: Active HD-tDCS; DRUG: Antipsychotics, mood stabilizers, etc.; DEVICE: Sham HD-tDCS. Primary outcome measures: Change from baseline in depressive symptoms assessed by the 17-item Hamilton Depression Rating Scale (HAMD-17) at Week 2. , Baseline and after 2 weeks.. Brief summary: This randomized, double-blind, sham-controlled clinical trial aims to evaluate the efficacy and underlying biological mechanisms of HD-tDCS targeting the primary somatosensory cortex in adolescents with bipolar depression. Participants will be randomly assigned to receive either active HD-tDCS or sham stimulation, in addition to routine clinical care. Biological data, including neuroimaging, blood biomarkers, voice and facial features, Photoplethysmography (PPG), Electroencephalography (EEG), and behavioral data, will be collected to explore potential predictors of treatment response.
