Study on Depression is Flawed
Chuck Ruby, Ph.D.
The WebMD study here is just as flawed as previous "breakthroughs" about biological markers for depression. It is misleading and weak because it is built upon a very flimsy assumption that depression is a disease rather than an understandable reaction to a life situation. The assumption is presented early in the article with a sleight of hand and repeated with the use of biological, medical, and illness words, giving the impression that depression is a disease. Yet, despite this assumption, no evidence is ever given to demonstrate the disease nature of depression. That's because there isn't any such evidence.
The absurdity of this also rests on the fact that depression is conventionally diagnosed by using a checklist of reported symptoms and behaviors. The checklist is contained the the psychiatric "bible", the DSM. Nowhere in that checklist is any mention of laboratory tests. That's because there is no bodily malfunctioning to test, as there is in diabetes, where a real disease process is happening.
The blood tests in this article do not identify disease or in any other way a malfunctioning of the body or brain. These tests merely demonstrate that human experiences (including depression) are accompanied by bodily "happenings". But this also happens with singing, crying. laughing, and playing golf. Those activities have their own "biological markers". The point here is that biological markers do not necessarily equal disease.
Imagine the absurdity of an article that says biomarkers have been found to diagnose "Athletic Deficit Disorder". Those biomarkers are identified as less muscle tone, smaller muscle mass, overweight, and shorter limb structures. Scans show decreased blood flow to the muscles, and probably differences in genetic markers. This would make sense only if we assume "ADD" (as above) is a disease to be diagnosed.
This article reports on research that adds to a long line of attempts to take basically existential human struggles and turn them into illnesses by showing biological correlates of the struggles. Damage will be done by using such biomarkers to screen people for depression, and then bear down on them with the coercive weight and authority of the psychiatric-industrial complex.
