What is depression?

Depression is a disorder that involves feelings of sadness lasting for two weeks or longer, often accompanied by a loss of interest in life, hopelessness, and decreased energy. Such distressing feelings can affect one's ability to perform the usual tasks and activities of daily living.

Depression is not a weakness of character. Being depressed does not mean that a person is inadequate. It means the person has a medical illness that is just as real as diabetes or ulcers. Like other medical disorders, clinical depression should not be ignored or dismissed. A clinically depressed person cannot simply "snap out of it" any more than a person with an ulcer could simply will it away.


But depression is highly treatable in the vast majority of cases. Up to 90% of depressed people respond positively to one treatment or another. Sometimes psychotherapy or counseling is all that is needed, but there is also a wide array of effective antidepressant medications and other alternatives. Sometimes, the first treatment will work well. At other times, a second or even a third treatment trial is required to find the best (most effective, most easily tolerated) treatment for the individual patient.




Clinical depression, is an umbrella term used to describe the most common forms of depression, which include:


Major depression, also known as melancholia or unipolar depression, can last up to a year if not treated. A person experiencing an episode of major depression will experience some physical problems, such as headaches, other aches and pains, or digestive upset, for example, in addition to emotional difficulties.


Bipolar disorder,  once called manic depressive illness, causes mood swings that soar to unusual elation, and then plummet to depression. A person with severe bipolar disorder may also see or hear things that are not there or experience paranoia (an incorrect feeling that they are in danger from others).

Dysthymia, is a chronic (ongoing), low-grade depression. It often begins in childhood or adolescence and may last for many years in adulthood if not treated. It is a less severe form of clinical depression, but at times it can be almost as disabling as major depression.

Seasonal affective disorder, (SAD) is a form of depression thought to be triggered by a decrease in exposure to sunlight. In the Northern Hemisphere, the condition usually occurs in late fall and winter, when daylight hours are short, and it is more common in geographical areas that have four clearly defined seasons.
