Continued neglect of the mental health needs of children and adolescents is unacceptable and must stop. WHO is ready to provide the support that can facilitate services development in both developing and developed countries. In partnership with other institutions and organizations, WHO will be part of the future efforts for improved services for children and adolescents. The work on the Child and Adolescent Mental Health Atlas was carried out by WHO in close collaboration with the WPA Presidential Global Programme on Child Mental Health and with the International Association for Child and Adolescent Psychiatry and Allied Professions (IACAPAP).
