A massive genomewide analysis of approximately 200,000 military veterans has identified six genetic variants linked to anxiety, researchers from Yale and colleagues at other institutions report Jan. 7 in the American Journal of Psychiatry.
Some of the variants associated with anxiety had previously been implicated as risk factors for bipolar disorder, posttraumatic stress disorder, and schizophrenia.
The new study further contributes the first convincing molecular explanation for why anxiety and depression often coexist.
At the risk asking a silly question, is this research using veterans as a study group just for convenience or, is it saying vets are more susceptible to these variants and therefore more susceptible to anxiety and depression and ptsd?
Possibly it may be because there have been more "trigger events" in their lives, it could also be equally possible that it was just a convenient data set to work from. Either way it does not detract from the findings of the study.
