Europe is facing massive challenges in child and adolescent mental health. Fortunately most people in Europe enjoy a high quality of life: according to the World Health Organization (WHO, 2001), 80% of young people report a good psychological well-being. However, one  adolescent out of  five  has cognitive, emotional and behavioral difficulties and one  adolescent out of  eight suffers from a diagnosable mental disorder, and the prevalence is increasing decade by decade. Suicide associated with depression, substance abuse, eating disorders, conduct disorders, attention deficit hyperactivity disorders (ADHD) and post traumatic stress disorder (PTSD) in children are all deserving concerted action.  Developmental psychiatric disorders  rarely have a spontaneous remission and may cause difficult social adaptation or mental disorder in adult life if not early diagnosed and treated.http://www.escap-net.org/index34e2.html?option=com_content&task=view&id=17&Itemid=31
