Link Between Brain Connectivity and Suicide Risk Identified.

Researchers have identified a potential marker in the brain that might indicate an increased risk of suicide. They observed that veterans with a history of suicide attempts demonstrated distinct functional connectivity between cognitive control and self-referential thought-processing networks. This connectivity pattern was present both before and after a suicide attempt, making it a potentially crucial indicator of suicide-specific risk. The study also suggests that suicide attempts could lead to brain changes, potentially escalating future suicide risk.
