Официальное название
Early TMS-EEG Potentials as Biomarkers for Personalized Neuromodulation in Treatment-Resistant Depression (R61 Phase)
Обзор
This study tests whether a brain stimulation treatment for depression called intermittent theta burst stimulation (iTBS) can be improved by tailoring it to each individual. A type of brain signal measured with electroencephalography (EEG) after a single pulse of brain stimulation, called an early local TMS-evoked potential (EL-TEP), is used to identify which stimulation settings work best for each participant. The investigators will compare individualized (personalized) iTBS settings to standard (non-personalized) settings and to inactive (sham) stimulation. Participants are adults with treatment-resistant depression.
Вмешательства
- Устройство Personalized iTBS
Intermittent theta burst stimulation delivered to the left dorsolateral prefrontal cortex using individualized pulse count (600, 1200, or 1800 pulses) and intensity (90% or 120% rMT) determined by EL-TEP screening. - Устройство Non-Personalized iTBS
Intermittent theta burst stimulation delivered to the left dorsolateral prefrontal cortex at fixed parameters: 1800 pulses, 120% resting motor threshold. - Устройство Sham iTBS
Inactive sham stimulation using a shielded coil with electrical scalp stimulation to mimic sensory experience of active iTBS.
