Depression
Everyone occasionally feels blue or sad.But these feelings are usually short-lived and pass within a couple of days.Depression is a common but serious illness.
Major depression prevents a person from functioning normally.It interferes with a person's ability to work,sleep,study,eat,and enjoy once-pleasurable activities.Minor depression is character-ized by having symptoms for 2 weeks or longer that do not meet full criteria for major depression. Without treatment,people with minor depression are at high risk for developing major depressive disorder.
The severity,frequency,and duration of symptoms vary depending on the individual and his or her particular illness.They include persistent sad,anxious,feelings of hopelessness,guilt,worth-lessness,or helplessness,loss of interest in activities or hobbies once-pleasurable,fatigue and decreased energy,difficulty in concentrating,remembering details,and making decisions,insomnia, early-morning wakefulness,or excessive sleeping,suicide attempts.
Depression also may occur with other serious medical illnesses such as heart disease,stroke, cancer,HI V/AIDS,diabetes,and Parkinson's disease.
Depression is related to a combination of genetic,biological,environmental,and psychological factors.Research indicates that depressive illnesses are disorders of the brain.Brain-imaging tech-nologies,such as magnetic resonance imaging(MRI),have shown that the brains of people who have depression look different than those of people without depression.Some types of depression tend to run in families.In addition,trauma,loss of a loved one,a difficult relationship,or any stressful situation may trigger a depressive episode.
Biological,life cycle,hormonal,and psychosocial factors that women experience may be related to women's higher depression rate.For example,women are especially vulnerable to developing postpartum depression after giving birth.Besides,during the transition into menopause,some women experience an increased risk for depression.It is still unclear,though,why some women faced with enormous challenges develop depression,while others with similar challenges do not.

A.feelings of guilt or worthlessness
B.developing postpartum depression after giving birth
C.going through a transition into menopause
D.symptoms for 2 weeks that is slightly different from major depression
