This fact sheet addresses the mental health needs of children and adolescents. It emphasizes that children and adolescents can have mental health problems, that these mental health problems can be severe, and that these problems are common in young people. Some causes of mental health problems are identified, such as exposure to environmental toxins, violence, or chronic poverty. Warning signs of possible mental health problems are listed, such as feelings of sadness and hopelessness, anger, and fearfulness and big changes in behavior patterns. Mental health problems are seen as limiting young people and as leading to such problem behaviors as substance abuse or law breaking. A variety of mental health services are listed, although it is stressed that finding the right services requires an individualized approach. The fact sheet ends with a plea for more public awareness concerning the needs of an estimated two-thirds of young people with mental health problems who are not receiving any services. (DB)
