Pathological Demand Avoidance

"Pathological Demand Avoidance Syndrome is a pervasive developmental disorder related to, but significantly different from, autism and Asperger syndrome. First identified as a separate syndrome at the University of Nottingham, research has continued at the Elizabeth Newson Centre. Children with PDA would previously have been diagnosed as having 'non-typical autism/Asperger' or 'pervasive developmental disorder not otherwise specified'; but it is important to diagnose them separately since they do not respond well to the educational and treatment methods that are helpful with autistic and Asperger children" (taken from www.pdacontact.org.uk)
