Contraindications to TMS or MRI, including patients who have
- conductive, ferromagnetic or other magnetic-sensitive metals implanted in their head or within 30 cm of the treatment coil (e.g., cochlear implants, implanted electrodes/stimulators, aneurysm clips or coils, stents, bullet fragments or jewelry)
- active or inactive implants, including deep brain stimulators, cochlear implants, vagus nerve stimulators or implanted device leads

iTBS rTMS Vertex then Lateral Parietal Cortex (LPC)
iTBS rTMS Vertex only
Subjects will receive 10 consecutive days of daily single session of iTBS rTMS for 3.5 minutes per day over the DLPFC in the first treatment period, complete a washout period of 4 weeks then receive 1 session of iTBS rTMS for 3.5 minutes daily over the vertex for 10 consecutive days.

Cognitively normal and healthy controls will receive 1 session of iTBS rTMS for 3.5 minutes daily over the vertex for 10 consecutive days. The vertex serves as a control as there are no functional improvements in cognition with stimulation of the vertex region.
