Unveiling the Link Between Neural Responses and Suicidal Ideation

The way the brain responds to rewards and losses may serve as a brain-based marker for suicidal ideation in individuals with depression and social anxiety, according to a study published in Biological Psychology. The researchers found that lower reward sensitivity was associated with higher levels of suicidal ideation, regardless of the specific diagnosis. Cognitive-behavioral therapy and supportive therapy were both effective in reducing symptoms of social anxiety and depression, but reward sensitivity remained stable throughout treatment, suggesting it may be a vulnerability marker for suicidal thoughts. Further research is needed to replicate the findings and explore other potential pathways leading to suicidal ideation.
