No one said they were. Researcher was looking for mood changes in normal individuals.
Quit trying to treat symptoms, and treat the underlying cause.
Well, neuropsychopharmacology is certainly meant to treat the underlying cause. I hope you aren't implying that all depression are situational in etiology. Would make it rather difficult to explain offspring raised separately from parents who manifest the same psychiatric symptoms, in addition to both possessing biochemical markers linked to the disorder.
If researcher was looking for mood changes in normal individuals, then magic mushrooms would do the trick. Smart researcher, not only gets to get his friends high on class one drugs supplied by the Government, but gets paid to do it.

However I do suspect the primary cause of depression is adrenal burnout. As a side note, Nutritional therapy with high enzyme foods with a high mineral content DOES rapidly replete the body and reduce depression symptoms far faster than any therapy that I know of. I know of a Naturopathic Doctor that is very excited because some of his patients are showing marked improvement in a few months eating some rather custom tailored sour Kraut recipes from a local home kitchen movement group.
While I know the theory and have felt the benefits myself, I am no where near ta Kraut maestro. I can share the basic premise with you if you wish.
