Who Develops Depression and Why

People of all ages, races, ethnic groups and social classes can become depressed. It can occur at any age. More women than men experience depression. Hormonal changes associated with the life cycle may trigger depression in some women. Untreated depression is also a common disorder among the elderly. Even children can experience clinical depression.

It's important to recognize that having a mood disorder like depression is not a character flaw or a sign of personal weakness. Researchers say that severe depression is caused by an imbalance in brain chemicals. The disorder can even run in families. Obviously, a mood disorder caused by these conditions is not the result of a lack of will power or a bad attitude.

Depressed people with an imbalance of chemicals in the brain can't make themselves well by trying to "snap out of it" or "lighten up" -- no matter how much they try.

They need treatment to restore balance in brain chemicals.
