According to some studies, depression afflicts between 6% and 12% of American high school students. Depression in children and adolescents is easily missed unless parents, teachers and medical personnel recognize its signs and symptoms. Without the ability to recognize these symptoms, the first inkling a parent may have of the severity of a child's illness is the tragedy of a completed suicide. Sometimes suicide is the first sign to parents that their child was depressed. Families and professionals review symptoms and recommend appropriate actions to take when it is suspected that a child or adolescent is at risk.
