Is there a biological basis for depression? Certainly, according to Dr. Mark Rasenick, a professor of physiology, biophysics and psychiatry at the University of Illinois Chicago. Even then, he contends that we know too little about the disease to even begin to treat it effectively, let alone stem its rising tide in the global population.

I share his sentiment that the medical professionals erroneously see medication the magic bullet to cure depression. Yet one needs to interpret with caution his assertion that depression is a "biological, medical problem" that often requires "long-term treatment." The relationship between biological and emotional aspects of depression remains a chicken-and-egg puzzle: does one feel depressed because of a chemical imbalance in the brain, or does feeling depressed lead to such imbalance?

So many people struggle with this. A lot of them go untreated, but it can be treated successfully.

The subject will always be actual. Sure, addiction can impair everybody to one extend or another. And not only alcohol or drugs, but even such "innocent" foods, as sugar, coffee, tea, even herbal tea. Depression is main, but not only one condition from more general category of mood disorders and establishing "dual" or even "triple" diagnosis could have little help. Most probably, the solution is hiding not in medical, but social environment.
