A study links reduced brain communication in assault survivors to PTSD, suggesting a biological marker.
A new study finds that many women with PTSD from recent sexual assault show a significant reduction in communication between the amygdala and prefrontal cortex—brain regions critical for fear processing and emotional regulation.
Researchers from Barcelona studied 40 women and found near-zero synchronization in 22, a pattern linked to persistent fear and emotional instability.
While not tied to symptom severity, the brain disconnect may serve as a biological marker for PTSD.
The findings, presented at a European neuroscience conference, highlight underrepresentation of sexual assault in trauma research and suggest potential for future personalized treatments, though larger studies are needed to confirm results.
