Depression is a medical condition characterized by long-lasting feelings of intense
sadness and hopelessness coupled with additional mental and physical changes.
The condition often affects a person's personal, social, and professional life.
About one in 5 women and one in 10 men will suffer from depression at some point in life.
Depression in children and adolescents occurs less commonly than in adults. Over 15.5 million Americans have serious depression at any given time, but less than one third of these people seek medical help.
