A Relation Between Craving Induction and Treatment Response in Deep Transcranial Magnetic Stimulation (dTMS) for Reducing Antipsychotic-induced Weight Gain in Schizophrenia (dTMS)

Подробное описание
The underlying causes of antipsychotic-induced weight gain are still unknown. Some research point out that it has something to do with metabolic disturbances and changes in appetite and food intake. With fMRI study, it is reported having dysfunction between prefrontal and insula cortex of its cognitive regulation, interoceptive signals and reward control. dTMS, H4 coil in particular, simultaneously targets prefrontal and insula cortex. Previous study has been deconstrued that dTMS could significantly improve weight gain. Moreover, it is reckoned that TMS has state-dependent effects on brain circuitry, suspected that symptom provocation may be made it more susceptible to modulation which may improve response. Therefore, this study is to explore the efficacy of dTMS on antipsychotic-induced appetite, and whether provoking symptoms can improve dTMS clinical responses.
With regard to investigate this, the investigators will be carried out a randomized single session dTMS, crossover, sham controlled clinical trial. 30 Patients with schizophrenia will be randomly treated with dTMS after food cue induced craving (FCC), dTMS without FCC and sham condition without FCC. Each session has three days intervals for washout. The follow-ups are at the baseline and after each session immediately. The main outcome measures include the change in Food-Cravings Questionnaires state (FCQ-S) score, Visual Analogue Scale (VAS) score, changes in Stop-Signal test (SST) behavioral assessment and the resting-state functional magnetic resonance imaging data.

Экспериментальный: Active dTMS after food cue induced craving (dTMS+FCC)
Participants will receive single session of active-dTMS to the bilateral insula and prefrontal cortex with H4 coil after food cue induced craving by watching the personalized video based on each participant's favorite food choices
|
The study will utilize the H4 coil to administer active Deep Transcranial Magnetic Stimulation (dTMS) to the bilateral insula and prefrontal cortex by Intermittent theta burst stimulation (iTBS).
The stimulation intensity is set at 90% of resting motor threshold (RMT), and the other parameters are set to triplet 50Hz bursts, repeat at 5Hz, 2s seconds on and 8 seconds off, 1800 pulses per session, total duration of 9 minutes and 52 seconds.

Активный компаратор: Active dTMS after non food cue induced craving (dTMS+NON FCC)
Participants will receive single session of active-dTMS to the bilateral insula and prefrontal cortex with H4 coil after neural visual stimulation by watching non-food and non-food related video

Food Craving Questionnaire State, FCQ-S
Временное ограничение: Baseline (Day 1); immediately before and immediately after (within 30 minutes post-session) each daily dTMS session (Day 1, 5 and 9)
|
The assessment of food cravings.
The FCQs consists of 15 items to be scored on a 5-point scale ranging from strongly disagree to strongly agree.
Its original form comprises five subscales measuring current food craving in relation to (1) an intense desire to eat, (2) anticipation of positive reinforcement, (3) relief from negative states, (4) lack of control over eating, and (5) hunger.

Baseline (Day 1); immediately before and immediately after (within 30 minutes post-session) each daily dTMS session (Day 1, 5 and 9)

The SST aims to access cognitive behavioral inhibition control.
The study employed a task that comprised randomly interleaved NoGo and Stop-Signal trials to examine both types of inhibition.
The study measured six behavioral parameters of interest: namely Mean Go reaction time (GoRT), Stop-Signal mean reaction time (SSRT), Stop-Signal delay (SSD), Target accuracy, Go trial accuracy, and NoGo Accuracy.
The SST main outcome is the changes of Stop-Signal mean reaction time (SSRT)
