Clinical depression is one of many mental disorders affecting 1 in 10 Americans today.

There are many possible causes of major depression; however, very often the disease strikes without any triggering cause which leads to a great deal of frustration by the affected person and his or her loved ones. Fortunately, scientists have narrowed the list to three major causes: a first depressive episode caused by a traumatic event, a biochemical disorder, or an inherited disorder.
Depression can result from an emotionally or physically stressful incident. This has been termed by psychologists as first depressive episode. Possible causes include the death of a loved one, an abortion or miscarriage, a move to a new home or job, the end of an important relationship, financial problems, a chronic illness, or any other traumatic event. For many people, these incidents produce a mild to moderate case of the blues. They feel "down" for a while, but they are able to continue functioning and performing everyday tasks.

    Although historically depression has been considered a character condition, evidence has accumulated suggesting the role of a biological substrate, namely serotonin, in subgroups of depressed patients. This accumulated evidence supports the indoleamine hypothesis of depression, which suggests that major depression results from a deficiency of available serotonin or inefficient serotonin. (16). We see that depletions of serotonin from certain regions of the brain such as the hypothalamus, amygdala, and cortical areas involved in cognition and other high processes, can have a great impact in contributing to depression.

I have also learned a little about what is believed to go on chemically in the brain of a clinically depressed person. I was also able to partially determine what sort of role genetics, chemicals and personal influences in the brain. Though I was unable to determine exactly how environmental and personal stress can cause a chemical imbalance in a person, I was even able to speculate about this issue and determine some theories of my own on why and how this may happen.

Because it is essentially an invisible illness and is largely in the mind, it is difficult to correctly diagnose it and most people suffer for months, years, or even decades with depression.
