Pathalogical Demand Avoidance syndrome
Background
Pathological Demand Avoidance syndrome: PDA
PDA is a pervasive developmental disorder related to, but significantly different from, autism and Asperger syndrome (see entry, Autism Spectrum disorders including Asperger syndrome). First identified as a separate syndrome at the University of Nottingham, research has continued at the Early Years Diagnostic Centre, which now holds a database of more than one hundred and fifty children and adults. These children 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, and since appropriate guidelines for education and handling are now available from the Early Years Diagnostic Centre.
