Depression: A Treatable Illness

Depression is a serious medical condition that involves the body, mood, and thoughts. It affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. A depressive disorder is not the same as a passing blue mood. It is not a sign of personal weakness or a condition that can be willed or wished away. People with a depressive illness cannot merely "pull themselves together" and get better. Without treatment, symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people who have depression.

Types of Depression

Depression comes in different forms, just as is the case with other illnesses such as heart disease. The three main depressive disorders are: major depressive disorder, dysthymic disorder, and bipolar disorder.

Major depression (or major depressive disorder) is manifested by a combination of symptoms (see symptom list below) that interfere with the ability to work, study, sleep, eat, and enjoy once pleasurable activities. A major depressive episode may occur only once, but it is more common for several episodes to occur in a lifetime. Chronic major depression may require a person to continue treatment indefinitely.

A less severe type of depression, dysthymia (or dysthymic disorder), involves long-lasting symptoms that do not seriously disable, but keep one from functioning well or feeling good. Many people with dysthymia also experience major depressive episodes during their lives.

Another type of depressive illness is bipolar disorder (or manic-depressive illness). Bipolar disorder is characterized by cycling mood changes: severe highs (mania) and lows (depression), often with periods of normal mood in between. When in the depressed cycle, an individual can have any or all of the symptoms of depression. When in the manic cycle, the person may be overactive, over-talkative, and have a great deal of energy. Mania often affects thinking, judgment, and social behavior in ways that cause serious problems and embarrassment. For example, an individual in a manic phase may feel elated and full of grand schemes that might range from unwise business decisions to romantic sprees.
