Pervasive Drive for Autonomy. PDA. Demand Sensitivity.

Whatever name you've been using, this is the site for the nervous system pattern underneath. Clinical framework. Practical tools. An honest contribution to the work of understanding, supporting, and caring for the people living with this.

What is Pervasive Drive for Autonomy?

The pattern, in 60 seconds

Some nervous systems experience everyday demands as threats. Not metaphorical threats. Actual physiological threat responses that fire before conscious choice is possible. The brain's threat-detection circuitry activates, the prefrontal cortex goes offline, and the survival brain takes over. What you see from the outside is refusal, shutdown, or meltdown. What's happening inside is a nervous system responding to a demand the way most nervous systems respond to danger.

The community calls it Pervasive Drive for Autonomy. The older clinical term is Pathological Demand Avoidance. We call it demand sensitivity, because that's what the nervous system is actually doing: registering demands differently, the same way some nervous systems are more reactive to sensory input or uncertainty. All of these terms describe the same pattern. The name you use matters less than understanding the mechanism underneath.

RELATE is a clinical framework built for this. Six pillars, each targeting a specific mechanism in the demand-threat cycle: Relationship, Empathy, Lower Demands, Adjust, Time, Environment. Plus a crisis triage protocol called ADAPT. It was built by clinicians working in residential treatment with complex neurodivergent populations. It is clinically informed, mechanism-based, and transparent about the current state of the evidence.

How the RELATE framework works

The RELATE library

Resources for the different people navigating demand sensitivity: clinicians who need intervention tools, parents who need to understand their child, and adults making sense of their own nervous system.

Licensed clinicians. Residential treatment. Intensive outpatient. Complex neurodivergent populations.

We work directly with people who have demand sensitive nervous systems in the settings where it's hardest. RELATE came from that work. Everything on this site comes from clinical experience with the population, not from theory about it.
