In August 2008, the World Federation of ADHD (Attention Deficit Hyperactivity Disorder) and allied disorders was founded in Zurich, Switzerland. Professor Andreas Warnke, Director of the Department of Child and Adolescent Psychiatry, Psychosomatics and Psychotherapy at the University of Würzburg, Germany, was officially nominated the first president of this non-profit organisation.
ADHD is a highly heritable childhood-onset psychiatric condition, which is characterized by age-inappropriate levels of the core symptoms inattention, hyperactivity and impulsivity. The disorder affects about 5 % of the children worldwide. Recent scientific studies in ADHD reveal biological underpinnings such as multiple genetic factors, ADHD-related differences in brain structure and function, as well as changes in neurotransmitter components within the basal ganglia thalamocortical neurocircuitries.
