Major depression is when five or more symptoms of depression are present for
at least 2 weeks. These symptoms include feeling sad, hopeless, worthless,
or pessimistic. In addition, people with major depression often have
behavior changes, such as new eating and sleeping patterns. Major depression
increases a person's risk of suicide.
The exact cause of depression is not known. Many researchers believe it is
caused by chemical imbalances in the brain, which may be hereditary or
caused by events in a person's life.
Some types of depression seem to run in families, but depression can also
occur in people who have no family history of the illness. Stressful life
changes or events can trigger depression in some people. Usually, a
combination of factors is involved.
Each year, more than 18 million Americans -- men and women of all ages,
races, and economic levels -- have depression. It occurs more often in
women.
Women are especially vulnerable to depression after giving birth. This is a
result of the hormonal and physical changes. While new mothers commonly
experience temporary "blues," depression that lasts longer than 2-3 weeks is
not normal and requires treatment.
Major depression can occur in children and teenagers, and they can also
benefit from treatment.
