Researchers may have found a biomarker for suicidal thoughts in the brains of people with post-traumatic stress disorder (PTSD), a new study suggests.https://www.livescience.com/65493-ptsd-suicidal-thoughts-biomarker.html
The study found that people with PTSD had higher levels of a certain receptor on the surface of their brain cells, compared with people without PTSD. And among people with PTSD, those who reported experiencing some suicidal thoughts on the day of their brain scan had even higher levels of this receptor, compared with those that did not report suicidal thoughts on the day of the scan.
The findings, published May 13 in the journal Proceedings of the National Academy of Sciences (PNAS), are preliminary, and more research is needed to better understand the connection between this receptor, PTSD and suicidal thoughts. [5 Myths About Suicide, Debunked]
