Brain scans may be able to identify people at risk of attempting suicide, say scientists who have discovered a chemical linked to suicidal thoughts in people with post-traumatic stress disorder (PTSD). The rsk of suicide among individuals with PTSD is much higher than the general population, but identifying those individuals at greatest risk has been difficult. Researchers at Yale University in the United States of America used PET imaging to measure levels of metabotropic glutamatergic receptor 5 (mGluR5) - which has been implicated in anxiety and mood disorders - in individuals with PTSD and major depressive disorder.
The study, published in 'Proceedings of the National Academy of Sciences, found high levels of mGluR5 in PTSD group with current suicidal thoughts.
