Blood Test Can Determine Depression And Its Subtypes In Teens

A breakthrough blood test which identifies depression and its specific subtypes in teens has been developed by a scientist at Northwestern University. Scientist were able to distinguish 11 specific genetic markers apparent within teens with depression and those without depression. Additionally, 18 out of 26 genetic markers previously identified, distinguished between teens who suffered major depression alone and those whose depression was coupled with anxiety disorders. This research is promising as, not only can depression and its subtypes be diagnosed through a simple blood test, but also gives hope for the development of individualized treatment options.

The findings so far suggest that women could benefit from stress reduction therapies, while men might benefit more from cognitive behavioral therapies or more traditional 12 step programs.
