Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The investigators hypothesis are as follows:

H1a: OEF/OIF veterans with PTSD who perform cognitive training (CT) will demonstrate greater objective improvements on standard (untrained) neurocognitive measures, with the largest gains in verbal memory, learning and sustained attention.

H1b: Objective cognitive improvements in CT participants will be sustained at three months post-intervention, suggesting persistence of neuroplasticity-based cognitive training benefits.

H2a: OEF/OIF veterans with PTSD who perform CT will report greater improvements in cognitive function.

H2b: OEF/OIF veterans with PTSD who perform CT will demonstrate improved social and occupational functioning and quality of life.

H2c: OEF/OIF veterans with PTSD who perform CT will demonstrate greater improvements in community reintegration.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Posttraumatic Stress Disorder (PTSD)-related cognitive dysfunction is well-described and has been associated with specific impairments in verbal memory, learning, attention and emotional regulation, deficits which have been correlated with abnormalities in specific brain regions. Both PTSD and cognitive dysfunction have been associated with impairments in social and occupational functioning and may contribute to operational or battlefield errors, soldiers' safety and threaten the success of military operations. In addition, following military service separation, PTSD-related cognitive impairment adversely impacts quality of life, readjustment, and community reintegration. A computerized neuroplasticity-based auditory cognitive training program (Plasticity-Based Adaptive Cognitive Remediation, Posit Science, San Francisco, CA) has been shown in several randomized controlled trials to improve verbal memory, attention, cognitive control, quality of life and daily function in community-dwelling elders and individuals with schizophrenia. To our knowledge however, there have been no studies of cognitive remediation training in individuals with PTSD. Therefore, the overall aim of this proposal was to investigate the efficacy of neuroplasticity-based auditory cognitive training in Veterans with PTSD and cognitive dysfunction. The primary specific aim of this pilot study was to examine change in objective cognitive function in Veterans with PTSD and cognitive dysfunction who participated in an open-label trial of an auditory cognitive training program. Our secondary aim was to examine change in self-reported cognitive function, social and occupational functioning, quality of life and community reintegration in Veterans with PTSD who participate in auditory CT. Finally, we evaluated the feasibility and usability of home-based computerized auditory cognitive training in Veterans with PTSD and cognitive dysfunction. We enrolled subjects in a program of 3 months of auditory cognitive training (CT) followed by 3 months of no contact. We assessed participants' change scores on neuropsychological outcome measures from pre- to post-treatment using reliable change indicators. We utilized qualitative thematic analysis to identify themes from participants about the feasibility, acceptability, and usability of the treatment. Information derived from this pilot study may be used to inform future cognitive training interventions for Veterans.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* An experienced clinical interviewer with Master's-level training will conduct first- and second-level screening to determine study eligibility for enrollment in the randomized controlled trial.

1. Confirmed OEF and/or OIF military service
2. Male veterans, ages 18 to 40 years with 12 to 16 years of education
3. History of a prior positive PTSD screen or diagnosis either by SFVAMC study referral or self-report'
4. Able and willing to travel to SFVAMC
5. Able and willing to perform daily home-based computer exercises for three months.
* The Second Level Eligibility Determination will occur in-person at the SFVAMC of potential participants who have met first-level screening eligibility criteria. Second-level eligibility screening will require signed informed consent (see below) before the second-level screening is conducted. During the second-level eligibility screen, consenting participants will be administered:

1. The Clinician-Administered PTSD screen (CAPS) and the Mini International Neuropsychiatric Interview (MINI) 29 to assess for Diagnostic and Statistical Manual (DSM)-IV Axis I psychiatric disorders
2. The VA TBI second-level screen \[TBI event history and Neurobehavioral Symptom Inventory (NSI) for cognitive symptoms\].30
* To be eligible for enrollment in the randomized controlled, veterans at second-level screening must:

1. Meet threshold criteria for current full or sub-syndromal PTSD by DSM-IV criteria 31
2. Report ≥ 1 moderate or severe cognitive symptom(s) on the NSI that interfere(s) with daily function including moderate to severe poor concentration, forgetfulness, difficulty making decisions and slowed thinking.
* Because PTSD is a highly comorbid condition, eligible participants may have other comorbid stable neuropsychiatric disorders, including depression or a history of a mild traumatic brain injury.

Exclusion Criteria

1. Poor English comprehension and fluency
2. Unstable medical condition, injury or disability, including moderate to severe TBI (by self-report) and hearing impairment
3. Current (or past 60 day) evidence-based PTSD or cognitive remediation therapy; in contrast, stable supportive therapy for PTSD and/or other mental disorders, such as group therapy or on stable psychoactive medication (\> 30 days) will be acceptable.

1. Drug and alcohol dependence and other unstable serious mental illness (e.g. psychosis) (assessed using the MINI)
