Pathological Demand Avoidance (PDA) is a Developmental Disorder which is distinct from Autism but however falls under the spectrum of related conditions.
It falls under the term PDD – NOS which refers to Pervasive Developmental Disorder Not Otherwise Specified, meaning you’re on the spectrum but cannot exactly place you (also meaning it can/will affect all areas of development).
First identified by Elizabeth Newson in 2003.
Although it is still not currently recognised in or by any tools used in the main for diagnosing autism, however it has now been recently recognised through the National Autistic Society.
It is a complex, challenging and very misunderstood condition that through lack of knowledge and understanding is often ignored or not even recognised by many professionals.
However, this mentioned it is worth noting that strategies which are helpful for learners with autistic spectrum disorder may not in the main be useful in cases of Pathological Demand Avoidance.
