A study links disrupted brain communication in assault survivors to PTSD, revealing a potential biological marker.
A new study finds that many women who develop PTSD after sexual assault show near-zero communication between the amygdala and prefrontal cortex, brain regions critical for emotion regulation.
Researchers from Barcelona studied 40 women using fMRI and found disrupted synchrony in 22, potentially explaining severe fear and emotional dysregulation.
While not linked to symptom severity, this brain pattern may serve as a biological signature of PTSD.
The findings highlight a gap in trauma research, historically focused on war or disasters, and suggest future potential for predicting treatment response, though larger, long-term studies are needed.
