Brief Summary:
The study will (1) assess feasibility of a TMS treatment in an underserved population; (2) determine if this TMS treatment protocol improves PTSD symptoms and biological markers of PTSD such as brain functioning and startle responses; (3) define new brain targets for future TMS studies; (4) provide the first data for individual differences, which will help personalize treatment for PTSD patients; (5) improve knowledge of the neurobiology of PTSD and treatment response.

Condition or disease Intervention/treatment Phase
Post Traumatic Stress Disorder Device: Transcranial Magnetic Stimulation (TMS) Procedure: Sham Transcranial Magnetic Stimulation (TMS) Not Applicable

Detailed Description:

Posttraumatic stress disorder is a psychiatric disorder that can develop in response to a traumatic event, and half of civilians living in inner-city areas with high levels of violence suffer from PTSD. The currently recommended treatment for PTSD is focused on discussing the trauma, but a third to half of patients cannot participate or do not benefit from this treatment, especially individuals with low levels of education or literacy. Therefore, new treatments for PTSD are needed.

The study will (1) assess feasibility of a TMS treatment in an underserved population; (2) determine if this TMS treatment protocol improves PTSD symptoms and biological markers of PTSD such as brain functioning and startle responses; (3) define new brain targets for future TMS studies; (4) provide the first data for individual differences, which will help personalize treatment for PTSD patients; (5) improve knowledge of the neurobiology of PTSD and treatment response.

Arm Intervention/treatment
Experimental: Transcranial Magnetic Stimulation (TMS)
TMS is a noninvasive treatment that uses magnetic fields to induce a small electric current in specific brain regions.
Device: Transcranial Magnetic Stimulation (TMS)
10-day treatment (2 per day with 10 minute break, 20 sessions in total) of active Transcranial Magnetic Stimulation (TMS). TMS is a noninvasive treatment that uses magnetic fields to induce a small electric current in specific brain regions.

Sham Comparator: Sham Transcranial Magnetic Stimulation (TMS)
Sessions of Sham Transcranial Magnetic Stimulation (TMS) will be conducted.
Procedure: Sham Transcranial Magnetic Stimulation (TMS)
10-day treatment (2 per day with 10 minute break, 20 sessions in total) of sham control.
