Major Depressive Disorder Clinical Trial
Official title:
Personalized Brain Functional Sector-guided rTMS Therapy Over Different Targets for Treatment-resistant Depression
To explore the effectiveness and safety of rTMS intervention with different targets in the left prefrontal cortex defined using the pBFS method, in adult patients with moderate and severe depressive disorder. Second, investigate the neural circuit that responds to the rTMS intervention using individualized brain image analysis, which may help to establish an effective target for the neuromodulation of patients with major depressive disorder.

Primary | change in MADRS | A provider-administered questionnaire was used to assess remission and recovery from depression. The MADRS is a ten-item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. The MADRS has an overall score range from 0-60, with higher scores corresponding to higher levels of depression | Baseline, Day 14(immediate post-treatment) | |
Secondary | change in MADRS | A provider-administered questionnaire was used to assess remission and recovery from depression. The MADRS is a ten-item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. The MADRS has an overall score range from 0-60, with higher scores corresponding to higher levels of depression | Baseline, Day 7, Day 14, Day 21 | |
Secondary | change in HAMD | A provider-administered questionnaire was used to assess remission and recovery from depression. The Hamilton Depression Rating Scale (HAMD) is the most widely used clinician-administered depression assessment scale. The Ham-17 version consists of 17 items assessing mood, guilt, general somatic symptoms, work and activities, anxiety, and slowness of thought and speech. Each item is scored on a scale of 0 to 4, except for the somatic, sleep, and insight items which are scored 0 to 2. On the HAMD-17 there can be a total score of 52. Higher scores represent higher depression severity | Baseline, Day 7, Day 14, Day 21 | |
Secondary | cognitive change in Digit Symbol Substitution Test (DSST) | Cognitive scores are measured using Chinese brief cognitive test (C-BCT), the DSST equires a subject to match symbols to numbers according to a key located on the top of the page | Baseline, Day 14(immediate post-treatment) | |
Secondary | cognitive change in a continuous performance test (CPT) | CPT from the C-BCT measures a person's sustained and selective attention | Baseline, Day 14(immediate post-treatment) | |
Secondary | cognitive change in Trail-Making Test (TMT) | The TMT test from the C-BCT can provide information about visual search speed, scanning, speed of processing, mental flexibility, and executive functioning | Baseline, Day 14(immediate post-treatment) | |
Secondary | cognitive change in Digit Span Test (DST) | DST from the C-BCT is a measure of verbal short term and working memory that can be used in two formats, Forward Digit Span and Reverse Digit Span | Baseline, Day 14(immediate post-treatment) |
