Adolescence is supposed to be full of ups and downs.But when the downs become persistent and obvious，it may signal a more serious psychological condition.Between 6% ~ 8% of American teenagers suffer from major depression，a disease that sometimes leads to suicide.Major depression can often be successfully treated—if it is recognized.But diagnosis is especially difficult in teens.

Teenagers can be and are uncommunicative.And some behaviors that parents may interpret as rebellious behaviors may in fact be serious symptoms of depression.

Although it can be difficult to distinguish from the typical growing pains of adolescence，there are some warning signs of major depression that parents should be aware of.If a teenager is trying to avoid relationships or constantly becomes seriously angry，more than normal teenage rebellion may be going on.In addition，frequently getting into trouble is another warning sign.Teenagers who begin to engage in serious antisocial behavior，whether it be drugs or sexual activity，etc.，often suffer from serious underlying depression.The warning signs can be difficult enough to recognize;but the problem of identifying major depression in teens is further complicated by the fact that even these ambiguous signs are not always present.

The greatest danger associated with major depression is the possibility of suicide.Suicide is the third leading cause of death among Americans between the ages of 15 and 24.After a suicide，loss and guilt are two feelings that family members must come to terms with.In half the cases of teen suicides，there was no suspicion that the victim had such serious feelings of depression.But afterward，it is common for loved ones to remember signs they may have missed and blame themselves for not intervening.

One expert recommends that the families of suicide victims seek support from each other，their friends，and professional counselors.Although friends may not like to speak about the suicide with the victim‘s family，allowing the family to talk is critical.For the most part，they desperately want to be able to tell their story.
