Accelerated iTBS for Depression: Monitoring Brain Hemodynamics With Simultaneous iTBS/fNIRS
Recruiting now · Not applicable
Conditions studied: Depression
In brief
This study will investigate the cortical hemodynamic response variability of an accelerated form of TBS stimulation over left dorsolateral prefrontal cortex (DLPFC) using a concurrent TBS/fNIRS setup. The accelerating TMS protocol that will be used in this study is similar to the Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT), i.e., fifty iTBS sessions (1,800 pulses per session, 50-minute intersession interval) will be delivered as 10 daily sessions over 5 consecutive days at 90% resting motor threshold. The investigators will recruit a depressed patient and conduct a concurrent iTBS/fNIRS protocol for each iTBS session. Moreover, the depression symptoms of the patient will be assessed before and after treatment.
