NCT07868627

Brief Summary

This study is testing whether combining a rapid form of transcranial magnetic stimulation (TMS), an oral medication called d-cycloserine (DCS), and therapy can improve brain flexibility and emotional control in adults experiencing moderate-to-severe depression, anxiety, or trauma symptoms. TMS is a non-invasive treatment that uses gentle magnetic pulses to stimulate specific areas of the brain. In this phase of the study, all participants receive active accelerated TMS (delivering multiple brief sessions in a single day) along with DCS, a medication that helps enhance brain learning and plasticity. Participants will be randomly assigned to have TMS directed at one of two brain targets: a region called the precuneus (identified using personalized brain scans) or the dorsolateral prefrontal cortex (a standard area for mood treatment). Afterward, participants are randomly assigned to complete three weeks of either therapist-led talk therapy (a modified Unified Protocol) or self-guided educational videos and readings. The main goals are to determine which brain stimulation target works best and to see whether therapist-led therapy leads to more lasting symptom relief and brain changes compared to self-guided education.

Outcome Measures

Primary Outcomes (3)

  • Patient Health Questionnaire 9 (PHQ-9)

    The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and measuring the severity of depression. The PHQ-9 test evaluates several factors that revolve around the criteria used to professionally diagnose depression under the current DSM-5. The total score is calculated and can range from zero to 27, with 27 being the highest and indicative of the worst outcome/severity. A score of 20 or higher indicates that severe major depression Scoring between 15 and 19 suggests that there is possibly moderately severe major depression Scoring between 10 and 14 means that you may have a moderate severity depression A score between 5 and 9 reveals that mild symptoms of depression appear to exist

    At each study visit, measured at Baseline, and 1-week, 1-month, and 3-months after treatment

  • Generalized Anxiety Disorder-7 (GAD-7)

    The Generalized Anxiety Disorder - 7 Item Scale (GAD-7) is a self-administered questionnaire designed for screening and measuring the severity of generalized anxiety disorder (GAD). The GAD-7 consists of seven items that respondents rate based on their experiences over the past two weeks, with each item scored from 0 (not at all) to 3 (nearly every day). The cumulative score, ranging from 0 to 21, indicates the severity of GAD symptoms, with higher scores corresponding to greater anxiety levels. This simplicity in administration and interpretation makes the GAD-7 a practical tool for healthcare providers to quickly assess anxiety levels and monitor changes over time.

    At each study visit, measured at baseline, 1-week, 1-month, and 3 months after treatment

  • Montgomery-Åsberg Depression Rating Scale (MADRS)

    The Montgomery-Åsberg Depression Rating Scale (MADRS) is a clinician-rated interview designed to assess the severity of depressive symptoms and detect change resulting from treatment. It consists of 10 items evaluating core symptoms of depression: apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, concentration difficulties, lassitude, inability to feel, pessimistic thoughts, and suicidal thoughts. Each item is rated on a 7-point scale ranging from 0 (symptom absent/normal) to 6 (severe/most abnormal). Individual item scores are summed to yield a total score ranging from 0 to 60. Higher total scores reflect greater depression severity (typically classified as 0-6: normal/absent; 7-19: mild; 20-34: moderate; 35-60: severe). Outcome values represent the change in total score from baseline, where negative change values indicate clinical improvement in depressive symptoms.

    At each study visit, measured at baseline and 1-week, 1-month, and 3-months after treatment
