Overview
Repetitive transcranial magnetic stimulation (rTMS) has been successfully used to help patients with treatment resistant depression. However, its role in alleviating self injuries without suicidal ideation remained uncertain. This trial will compare the effectiveness of active accelerated intermittent theta burst stimulation (aiTBS) rTMS to a placebo control on non-suicidal self injury (NSSI) in patients with unipolar disorder and bipolar disorder.
Description
The study will evaluate the efficacy and safety of aiTBS in unipolar and bipolar depressive patients with NSSI or suicidal thoughts and behaviors by measuring changes in clinical ratings at baseline, after all the treatments, and 2 weeks, 4 weeks after treatment. 60 inpatients will be randomized to receive active or sham interventions administered to the left dorso-lateral prefrontal cortex. The treatment will apply active aiTBS rTMS involving 1800 pulses (9 minutes), 5x daily at 60 minutes intervals for 5 days. Changes in mood and sleep from baseline to the end of the study will be measured with The Hamilton Rating Scale for Depression-17 item (HAM-D17), Hamilton Anxiety Scale (HAMA), Young's Mania Scale (YMRS), and Pittsburgh Sleep Quality Index (PSQI) . Non-suicidal self injury will be assessed by the Deliberate Self-Harm Inventory (DSHI) and the Ottawa self-injury inventory (OSI). Suicidal ideation and behaviors assessments include Beck Suicidal Scale Inventory (BSI), the Ottawa self-injury inventory (OSI) and several questions from Self-Injurious Thoughts and Behaviors Interview - Revised (SITBI-R). Improvement of cognitive dysfunction could be measured by Barratt Impulsiveness Scale-11 (BIS-11), near infrared spectroscopy (fNIRS). Treatment Emergent Symptom Scale (TESS) would be used to eliminate side effects of combined drugs at baseline and the adverse event record form (AERF) will be used to appraise the safety of aiTBS treatment using these parameters. To record the change in sensitivity to pain and examine the tolerability of the treatment for these participants, visual analogue scale (VAS) is employed after completing 5 sessions treatment every day.
