However, in the United States, women become depressed about twice as often as men. Depression can strike a person at any age. Even small children can become depressed if they experience a serious loss such as the death of a parent.

Today, more than 10 million Americans are being treated for depression. The personal history consists of the recent events associated with the depressed mood, a past history, and a family history.
