Change in Clinician Administered Posttraumatic Stress Disorder Scale (CAPS) [ Time Frame: Pre-treatment, after an average of 8 weeks of treatment, and 6 months post-treatment ] [ Designated as safety issue: No ]
The CAPS is a 30-item structured interview that corresponds to the DSM-IV criteria for PTSD. The CAPS can be used to make a current (past month) or lifetime diagnosis of PTSD or to assesses symptoms over the past week.

  • Change in Magnetic Resonance Imaging (MRI) data [ Time Frame: Pre-treatment, after an average of 8 weeks of treatment, and 6 months post-treatment ] [ Designated as safety issue: No ]
    MRI data consist of functional magnetic resonance imaging of parametric spatial working memory and sustained attention (i.e.., continuous performance task).
  • Change in Neuropsychological data [ Time Frame: Pre-treatment, after an average of 8 weeks of treatment, and 6 months post-treatment ] [ Designated as safety issue: No ]
    Neuropsychological evaluation provides primary outcome measurements from domains of attention and memory.

Neural Correlates of Cognitive Rehabilitation in PTSD
Neural Correlates of Cognitive Rehabilitation in Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) is commonly associated with deficits in attention and memory skills. As such, these deficits may negatively affect performance in other cognitive domains (e.g., memory, executive functions), leading individuals with PTSD to experience difficulties in everyday functioning and reductions in quality of life. Investigators therefore aim to examine whether U.S. Veterans with PTSD will benefit from engagement in targeted cognitive remediation by measuring longitudinal change in neuropsychological performance, neural activity, and clinical outcomes. The longitudinal research design for this project will be a three factor mixed factorial design with between subject factors of PTSD (+PTSD x -PTSD) and cognitive remediation (learning-based cognitive training [LBCT] x non-learning training [NLT]) and the within subject variable of time tested (pre-training, post-training, 3 month follow-up). Forty participants will be enrolled in four groups of 10 each: 1) +PTSD/LBCT, 2) +PTSD/NLT, 3) -PTSD/LBCT, and 4) -PTSD/NLT. All groups will receive 40 hours of computerized training. Outcomes will be measured at baseline (i.e., pre-treatment), after an average of 8 weeks of treatment, and at 6 months post-treatment. The active treatment is the Posit Science visual cognitive remediation paradigm (i.e., InSight), while the control treatment will utilize games face valid for cognitive training. This study will examine the effects of a standardized cognitive rehabilitation program on neurocognitive functioning and brain functional activation in OEF/OIF veterans with PTSD. The proposed study addresses several issues important to advancing the care of Veterans with PTSD. This project will comprehensively assess potential cognitive problems experienced by individuals with PTSD, which may benefit clinicians and researchers focused on the treatment of PTSD. It will also examine whether a sophisticated rehabilitation program that is rooted in clinical neuroscience (but also commercially available) can remediate these problems, and what structural and functional brain changes are associated with this remediation. Finally, it will examine whether changes associated with cognitive training persist over a longer-term follow-up period.
