Accelerated iTBS for Post Partum Depression

"The investigators will treat post-partum depressed subjects with accelerated intermittent theta burst stimulation. iTBS will be delivered via a MagVenture MagPro100 and Cool-B65 coil. The investigators will use a standard resting motor threshold (rMT) determination to determine the TMS dose. Treatment will be delivered at 120% of the motor threshold.~In study 1, the accelerated paradigm will consist of 10 such sessions separated by 15 minutes, for three treatment days per week. There will be 2 weeks of 10 sessions on each of three days for a total of six treatment days, divided by one treatment-free week between treatment weeks. In study 2, the accelerated paradigm will consist of 12 sessions per day for 5 total treatment days. Treatments will be delivered at the 10-20 EEG coordinate for F3 (approximating the left DLPFC), and will be found using the Beam-F3 method."
