Brief summary
This proposal seeks to carry out a double-blinded, randomized, comparative study that investigates neurobehavioral changes induced by personalized, anxiosomatic and dysphoric network guided accelerated intermittent-theta burst (iTBS) using dense functional Magnetic Resonance Imaging (fMRI) sampling in participants with treatment-resistant depression (TRD) and moderate/high levels of anxiety.

Eligibility
Inclusion criteria
* Male/female aged 21-70 * Diagnosis of MDD as validated by MINI * Non-response to adequate trial (4 weeks) of at least two MDD medication as verified by the study clinician * BDI score of 20 or above; BAI score of 16 or above * Able to give informed consent * Able to understand English
Exclusion criteria
* DSM-5 psychotic disorder * Drug or alcohol abuse or dependence (preceding 3 months) * Rapid clinical response required, e.g., high suicide risk * Significant neurological disorder, which may pose increased risks with TMS, e.g., epilepsy * Metal in the cranium, skull defects, pacemaker, cochlear implant, medication pump or other electronic device * Pregnancy * Unsuitable for MRI * With recent TMS or ECT treatment in past 3 months * Multiple stimulant medications
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rank- Transformed Ratio of Beck Depression Inventory (BDI) to Beck Anxiety Inventory (BAI) change | Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period. | The primary outcome will be the rank-transformed ratio of BDI change to BAI change (e.g. A patient has a 50% reduction in BDI and a 25% reduction in BAI, giving a BDI:BAI ratio of 50% ÷ 25% = 2.0. Another patient has a 40% reduction in BDI and a 25% reduction in BAI, giving a BDI:BAI ratio of 40% ÷ 25% = 1.6. Higher ratios indicate a relatively greater improvement in depression compared with anxiety within each patient. This ratio is then ranked across all patients.). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Inventory of Depression and Anxiety Symptoms-II (IDAS-II) | Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period. | IDAS-II is an ordinal self-report scale measuring depression, anxiety, and bipolar symtpoms ranging from 99-495. Higher scores mean worse outcome. |
| Penn State Worry Questionnaire (PSWQ) | Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period. | PSWQ is an ordinal self-report scale measuring pathological worry ranging from 16-80. Scores depend on whether the item is worded positively or negatively. |
| Interaction between TMS target and change in BDI and BAI | Baseline (before treatment), immediately after acute treatment (after 30 treatments over 1 week), and weekly during the 1-month follow-up period. | The investigators will test interactions between TMS Target and change in BDI and BAI (including baseline and weekly outcomes over one month) separately using repeated measures linear mixed effects models. |
