"Mental health is an important part of overall health for children as well as adults. For many adults who have mental disorders, symptoms were present—but often not recognized or addressed—in childhood and adolescence. For a young person with symptoms of a mental disorder, the earlier treatment is started, the more effective it can be. Early treatment can help prevent more severe, lasting problems as a child grows up." NIMH
