For PDA Action Week 2026 we’re partnering with PDA North America to create opportunities to get involved with the growing international community around PDA – as a source of information, support and solidarity.

Research into PDA is still limited, but what we do know suggests that around one in five autistic people could have a PDA profile. That means there may be millions of PDAers worldwide, still struggling to understand their experiences, or find others like them.

This interactive map brings together PDAers from all over the world. And as more people are coming home to their neurodivergence, this is a powerful reminder that PDAers are everywhere. You are not alone. You belong.

PDA or Pathological Demand Avoidance is commonly understood to be a profile of autism. The most well-known features of PDA is demand avoidance, which is where a person finds it hard to manage everyday tasks or demands, even those they want or need to do.

Without understanding and support, PDA can have a profound impact on people’s lives. Our mission is to make life easier by building awareness and understanding of PDA, and providing information, training and personalised support to everyone who needs it.

We are the only PDA charity in the UK and one of the only places that PDA families can turn to for support.

Our small team works tirelessly to raise awareness, provide one to one support, and deliver training to PDA adults, parents and professionals who supoort PDA autistic people.

But we’re reliant on people like you to keep going. Could you help somone have their lightbulb moment today?
