Pmdd Depression

Depression can be described as feeling sad, blue, unhappy, miserable, or down in the dumps. Most of us think this way at one time or another for short periods. But true clinical depression is a mood disorder in which feelings of sadness, loss, anger or frustration interfere with everyday life for an extended period.

The main types of depression include:

aec Major depression - five or more symptoms listed above must be present for at least two weeks, but major depression tends to continue for at least six months.
aec Dysthymia - a chronic, generally milder form of depression but lasts longer - usually as long as two years.
aec Atypical depression - depression accompanied by unusual symptoms such as hallucinations (eg hearing voices that do not exist) or delusions (irrational thoughts).
aec premenstrual dysphonic disorder (PMDD) - depressive symptoms occur one week before menstruation and disappear after menstruation.
aec Seasonal affective disorder (SAD) - occurs during the autumn-winter season and disappears during the spring / summer. Likely to be due to a lack of sunlight.

Causes of Depression
Depression often goes in families. It may be heredity, learned behavior, or both. Even with a genetic predisposition, it is usually a stressful life event or unhappy that triggers the onset of a depressive episode.

Depression can be caused by:
aec Disappointment at home, at work or school (in adolescents, it can be broken with a boyfriend or girlfriend, failing a class, or parents divorcing)
aec Death of a friend or relative
aec having a serious illness
aec Medications such as sedatives and antihypertensives
aec Alcohol or drug
aec Chronic stress
aec childhood events such as abuse or neglect
aec Social isolation (common in the elderly)
aec problems sleeping.
