What is it about?
Posttraumatic growth (PTG) is the advantageous change some people derive from their struggle to recover from trauma. This article uses EEG to measure brain activity associated with high versus low PTG, resilience, and PTSD. Results reveal limited, but potentially meaningful similarities between PTG, resilience, and PTSD. Higher posttraumatic growth was found to be significantly associated with higher alpha frequency power over the sensorimotor cortex in the left central brain area around EEG electrode C3.

Why is it important?
Our study offers the first comparative neural topographies of PTG, resilience, and PTSD symptoms in published literature. The results support the theory that PTG, resilience, and PTSD are co-occurring, yet distinct psychological constructs. The findings contribute to the emerging neural theory of posttraumatic growth and may be used in future research to develop well-being-focused treatments to enhance posttraumatic growth in people who have experienced trauma.
