Depression Types Explained
While this disorder may manifest in different ways to each individual, there are several common types of depression that many people experience:
1. Major Depressive Disorder (MDD)
Often referred to simply as "clinical depression," MDD is characterized by persistent feelings of sadness, hopelessness, and a loss of interest in activities once enjoyed. To be diagnosed, symptoms must last for at least two weeks and interfere significantly with daily functioning. Other symptoms may include changes in appetite, sleep disturbances, fatigue, difficulty concentrating, and thoughts of death or suicide.
2. Persistent Depressive Disorder (Dysthymia)
This form of depression is more chronic but typically less severe than MDD. Symptoms persist for two years or more and may fluctuate in intensity. People with dysthymia often describe themselves as feeling "down in the dumps" most of the time, and they may struggle with low self-esteem, low energy, and poor concentration.
3. Bipolar Depression
Bipolar disorder includes episodes of depression that alternate with periods of mania or hypomania (elevated or irritable mood, increased activity, inflated self-esteem). The depressive episodes in bipolar disorder often mirror those of MDD but are part of a larger mood cycle. Treatment usually involves mood stabilizers in addition to antidepressants.
4. Seasonal Affective Disorder (SAD)
SAD is a type of depression that follows a seasonal pattern, typically emerging in the fall and winter months when daylight hours are shorter. Symptoms may include fatigue, weight gain, social withdrawal, and increased sleep. Light therapy, along with traditional treatments like psychotherapy and medication, is often effective.
5. Postpartum Depression (PPD)
More intense and longer-lasting than the “baby blues,” postpartum depression affects some women after childbirth. It involves feelings of extreme sadness, anxiety, and exhaustion that may interfere with a mother’s ability to care for her baby or herself. PPD is treatable and should not be ignored.
6. Premenstrual Dysphoric Disorder (PMDD)
PMDD is a severe form of premenstrual syndrome (PMS) that causes significant emotional and physical problems in the days leading up to menstruation. Mood swings, irritability, depression, and tension are hallmark symptoms. Treatment may involve lifestyle changes, hormonal therapy, or antidepressants.
7. Atypical Depression
Unlike typical depression, atypical depression can include temporary mood improvements in response to positive events. Other symptoms often include increased appetite, excessive sleep, a heavy feeling in the limbs, and heightened sensitivity to rejection. It tends to respond well to specific types of antidepressants.
