Primary Outcome Measures:
  • Change From Baseline in PTSD Symptomatology at the Week 8 Timepoint. [ Time Frame: 8 weeks ]

    We will compare patients' symptomatology at baseline vs. at 8 week timepoint

    Specify Full Scale Name and Construct (i.e., indicate what the scale measures if not clear from name): Clinician-Administered PTSD Scale (CAPS)

    Include all scale ranges (i.e., minimum and maximum scores) required to interpret any values in the data table: 0-136

    For each scale range provided, specify which values are considered to be a better or worse outcome: 0-best, 136 worst

    If subscales are combined to compute a total score, consider indicating how subscales are combined (summed, averaged, etc.): summed

Arms Assigned Interventions
Experimental: Seroquel
This study will investigate therapeutic responses to Seroquel pharmacotherapy in PTSD
Drug: Seroquel
This study will investigate therapeutic responses to Seroquel pharmacotherapy in PTSD
Other Name: quetiapine

Detailed Description:
An initial telephone interview will be conducted to determine if potential subjects meet the basic study requirements. If no obvious counterindications are present, subjects will be scheduled for a screening visit. After briefing the subjects on the reasons for the research, they will be given an opportunity to read the Informed Consent Form, approved by the Cambridge Health Alliance Institutional ReviewBoard, and to ask questions prior to signing it. Subjects will be given a copy of the signed Consent Form. Each subject will complete a standardized interview schedule designed to obtain personal and background data along with psychodiagnostic and psychometric evaluations. An open-label treatment will be utilized for all patients. Seroquel tablets will be flexibly dosed and begun at a target dose of 25 mg per day and taken over an 8 week period.
