Pathological Demand Avoidance: Symptoms but Not a Syndrome

Year Published: 2018
Authors: Lisa Summerhill and Kate Collett

This article examines whether Pathological Demand Avoidance (PDA) should be considered a separate syndrome or simply a set of complex behaviours within or beyond autism. The authors review existing research and conclude that there is not enough evidence to classify PDA as an independent condition.

However, the term PDA does highlight real challenges faced by many children with autism, particularly in managing social, sensory, and cognitive sensitivities. The paper stresses the importance of recognising frequently co-occurring conditions and understanding how these factors interact with a child’s environment. Instead of focusing on PDA as a diagnosis, the authors advocate for individualised management strategies tailored to each child’s needs. They emphasise the need for strong collaboration between professionals and families to develop effective support, particularly in education and daily life. Clear communication and shared understanding are essential to improving outcomes for children and their families.
