In his 2005 book, The 21st Century Brain, neurobiologist Professor Steven Rose notes that “the net of mental distress and disorder has been cast ever wider as the psychiatric community seeks to classify as aberrant, or diseased, more and more aspects of the human condition.” He goes on to say:
What are the origins of this epidemic? How can it be that the three billion years of evolution that have generated the human brain have produced an instrument seemingly so superb, yet also so readily disturbed, so easily made dysfunctional? Is this vast psychiatric caseload the inevitable downside of the creativity and cognition that so conspicuously characterises our species?”

Steven Rose didn't cite a source for the statistic of 44 million Americans suffering from depression, but if anxiety disorders and depression are added together the official figures from the U.S. National Institute of Mental Health (NIMH) are higher [ link ].
Some individuals may be categorized with more than one diagnosis. Mild depression persisting for at least 2 years is labeled 'Dysthymic Disorder'. The chart below shows 2005 data (updated in 2010).
Can it be true, as bio-psychiatrists would have us believe, that depression and virtually all other mental disorders are the result of ‘genetic predispositions’ ? If so, then to be a member of Homo sapiens is to be a member of the species which best proves that genetic evolution can go haywire. What other animal has such a high chance of developing some type of mental disorder during its lifetime? Steven Rose clearly doesn't find the orthodoxy of ‘genetic predispositions’ adequate, and asks the question:
Regarding the apparent epidemic of ADHD among children in the US, he notes that until recently, British child psychologists were diagnosing ADHD at only one-tenth the rate found among young Americans. Steven Rose asks:
In any event, the UK, along with other European countries such as Sweden and Germany, is now catching up fast, although prescription rates are still much lower than in the US or Australia”

He restates his view on the depression epidemic a bit further on in the book:
