Positive Association Between Local Brain Hypercorrelations and Posttraumatic Stress Disorder (PTSD) Symptom Severity
Brain imaging in PTSD reveals how network rigidity correlates with symptom severity, potentially opening new targets for treatment monitoring or intervention.
This small fMRI study (n=36) found that PTSD is associated with local brain hypercorrelations — reduced intra-area network flexibility — that correlate with symptom severity, especially in frontal and limbic regions. While outside the primary watchlist, the AI/imaging and veterans-population intersection warrants flagging as an unsolicited find.
