Although this story contains interesting information on neuro-science advancements and discoveries that are potentially groundbreaking, the content-the science-based facts that support the claim- is thin. Both the title of the article, "Depression in Teens Could Be Diagnosed with Blood Test," and the abstract, "A blood test based on 11 genetic markers could make early-onset diagnosis easier and possibly relieve the stigma of depression," immediately grabbed my attention. However, I was disappointed by the vagueness and lack of science-based content within this article. The article delves into the statistics- the high link between adults suffering from depression and their blood samples containing "depression indicating" genetic markers. However, the article does not mention, whatsoever, what any of these "genetics markers" are. Moreover, the article mentions the social aspects of depression and "the stigma associated with depression," but fails to mention the biological aspects- the scientific proof/evidence supporting the issue.
