- Public-Health practice focused on depression, with Coon explaining `A tenet in suicide prevention has been that we just need to screen people better for associated conditions like depression,' and she cautioned expanded depression screening 'might not help' some at risk.
- Analyzing more than 2,700 genetic records, researchers found the hidden group had fewer psychiatric diagnoses and genetic risks for anxiety, depression, Alzheimer's disease, and post-traumatic stress disorder.
- Clinical follow-up work seeks to investigate chronic pain, inflammation and respiratory diseases, aiming to help doctors identify high-risk individuals earlier even without expressed suicidal thoughts.
