Types of depression

Depressive disorders come in different forms. There are several different diagnoses for depression, mostly determined by the intensity of the symptoms, the duration of the symptoms, and the specific cause of the symptoms, if that is known.

Psychology Information Online provides information on the following depressive disorders. Follow the title link for more information about each type of depression:

Depression

Major Depression (depressive illness) is a serious condition that result in extreme fatigue, sleep problems and eventually an inability to function. The exact cause is unknown, but it is thought to be a malfunction of brain neurotransmitters, which are chemicals that modulate moods. Major Depression is usually treated with a combination of psychotherapy and antidepressants which moderate or correct chemical imbalances in the brain. The group of antidepressants most frequently prescribed is the selective serotonin reuptake inhibitors (SSRIs) which regulate the neurotransmitter serotonin.

Examples:

Amitriptyline HCL
WELLBUTRIN
Wellbutrin SR
Fluoxetine
Celexa
Lexapro
Paxil
Prozac
Remeron
Zoloft
Effexor XR

• Major Depression - This is the most serious type of depression, in terms of number of symptoms and severity of symptoms, but there are significant individual differences in the symptoms and severity. You do not need to feel suicidal to have a major depression, and you do not need to have a history of hospitalizations either, although both of these factors are present in some people with major depression. There is no official diagnosis of "moderate depression."
• Dysthymic Disorder - This refers to a low to moderate level of depression that persists for at least two years, and often longer. While the symptoms are not as severe as a major depression, they are more enduring and resistant to treatment. Some people with dysthymia develop a major depression at some time during the course of their depression.
• Unspecified Depression - This category is used to help researchers who are studying other specific types of depression, and do not want their data confounded with marginal diagnoses. It includes people with a serious depression, but not quite severe enough to have a diagnosis of a major depression. It also includes people with chronic, moderate depression, which has not been present long enough for a diagnosis of a Dysthymic disorder. (You get the idea!)
