Effectiveness of Powell's Cognitive Rehabilitation with Neurofeedback in Improving Executive Functions, Memory, and Attention to Veterans with Post-Traumatic Stress Disorder

PTSD is a set of continuous and frequent symptoms that occur after experiencing or observing a traumatic event, such as being involved in a war. The aim of this study was to evaluate the effectiveness of Powell's cognitive rehabilitation with neurofeedback in improving executive functions, memory, and attention to veterans with post-traumatic stress disorder. Material & Methods: This semi-experimental study, with pre-test post-test design, was carried out on 24 veterans with post-traumatic stress disorder in two experimental and control groups. Powell's cognitive rehabilitation treatment with neurofeedback was performed for 12 sessions and three months for the experimental group. For conducting the study, PSSI test, Wisconsin Card Test, Stroop test, and working memory test were used. Data were analyzed using univariate covariance analysis and SPSS 24. Finding: By controlling the pre-test effects, there was a significant difference between the experimental and control groups in terms of overall score of executive functions, memory and attention (p=0.001). Powell's cognitive rehabilitation treatment with neurofeedback is effective on improving executive functions, memory and attention of veterans with post-traumatic stress disorder.
