There are several different types of depression, which are distinguished by their duration and severity of symptoms. Most of these kinds of depression are defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM) put out by the American Psychiatric Association:
Major Depressive Disorder:(also known as Major Depression, Clinical Depression) – A major depressive episode occurs with symptoms that last for most of the day, nearly every day for at least two weeks. A symptom must either be 1) depressed mood or 2) a noticeable decrease in interest or pleasure in all or most activities
Dysthymic Disorder:(or also referred to as Dysthymia) – Generally, this type of depression is described as having persistent but less severe depressive symptoms than Major Depression.
Manic Depression:(now known as Bipolar Disorder) – This kind of depression includes periods of mania and depression. Cycling between these two states can be rapid or only mania can be present without any depressive episodes. A manic episode consists of a persistent elevated or irritable mood that is extreme, which lasts for at least one week.
Post-Partum Depression: Major depressive episode that occurs after having a baby. Depressive symptoms usually begin within four weeks of giving birth and can vary in intensity and duration.
Seasonal Affective Disorder:(SAD) – A type of depressive disorder that is characterized by episodes of major depression, which reoccur at a specific time of the year (e.g. fall, winter). In the past two years, depressive periods occur at least two times without any episodes that occur at a different time.

What do you think of the various types of depression? Should treatment take mainly the same focus for each type? Why do you think it is important for patients to know what type of depression they suffer from? Does it matter?
