1 Classification by cause

The cause of depression is relatively complex and has not been fully identified. Currently, depressive disorders are clinically divided into primary and secondary depressive disorders: the former is a depressive disorder whose cause is still unclear; the latter is a depressive disorder secondary to substances (addiction or abuse of substances, drugs and toxic substances) or physical illness.

2. Classification by presence or absence of manic episodes

Depending on whether there is a manic episode or not, major depressive disorder can be divided into bipolar disorder and unipolar depressive disorder: only those with depression have manic episodes.

It is called unipolar depressive disorder; those who have both depressive episodes and manic episodes are called bipolar disorder.

3 Classification by onset time, severity and frequency

1Depressive disorder is a type of paroxysmal disease with varying durations of onset. Two weeks is usually used as the dividing line between brief depressive episodes and depressive episodes. An episode lasting from 2 days to less than 2 weeks is called a brief depressive episode; an episode lasting 2 weeks or more is called a depressive episode.

2 The severity of symptoms during a depression attack also varies: those with mild symptoms are called mild depression; those with severe symptoms are called major depression.

3 The number of depressive episodes varies with different depressive disorders. Some patients only have one episode of depression in their lifetime, which is called a single episode of depressive disorder; some patients relapse and have 2 or more depressive episodes, which is called recurrent depressive disorder.

4 Classification by symptom characteristics

1Depression (major depressive disorder with melancholic features): Symptoms of the current or most recent major depressive episode have melancholic features.

2 Psychotic depression (major depressive disorder with psychotic features): The current or most recent major depressive episode is accompanied by psychotic symptoms, such as hallucinations or delusions. People with delusions are also called delusional depression.

3 Catatonic depression (depression with catatonic features): Catatonic symptoms in the current or most recent major depressive episode. Those with stupor as the main symptom are also called stuporous depression.

4Atypical depression (depressive disorder with atypical features): The current or most recent major depressive episode or dysthymic disorder has atypical features.

5 Double depression: refers to a major depressive episode superimposed on a dysthymic disorder.

6. Hidden depression: refers to depression in which the physical symptoms are obvious but seem to mask the depressive mood.
