Computer-Based Executive Function Training for Combat Veterans With PTSD: A Pilot Clinical Trial Assessing...

Area of Science:

• Neuroscience
• Psychology
• Computer Science

Background:

• Evidence-based treatments for post-traumatic stress disorder (PTSD) are not fully effective for all individuals.
• Current PTSD treatments do not directly address associated neuropsychological deficits.

Purpose of the Study:

• To describe the methods and assess the feasibility of computer-based executive function training (EFT) as a potential PTSD treatment.
• To explore EFT's impact on psychological symptoms, neuropsychological function, and brain activity in combat veterans.

Main Methods:

• A placebo-controlled study involving male combat veterans with PTSD (n=20) and combat-exposed controls (n=20).
• PTSD participants were assigned to 6 weeks of home-based EFT (n=13) or placebo training (n=7).
• Assessments included clinical, neuropsychological, and functional neuroimaging measures before and after training.

Main Results:

• Dropout rates were 38.5% for EFT and 57.1% for placebo training.
• Baseline clinical severity and brain activation patterns predicted treatment completion.
• EFT participants improved on training tasks, but not on traditional neuropsychological tests; both groups showed symptom reduction.

Conclusions:

• Computerized, home-based EFT is a feasible intervention to explore for PTSD, impacting psychological and neuropsychological outcomes.
• Clinical severity and neural reactivity may identify veterans likely to complete such interventions.
• Further research is required to enhance compliance and establish EFT's efficacy beyond placebo effects.
