What is PDA?
PDA stands for Pathological Demand Avoidance, also commonly referred to as Pervasive Drive for Autonomy. It describes a neurodivergent profile where everyday demands are experienced as overwhelming or threatening, leading to avoidance that is driven by nervous system stress rather than defiance, laziness, or lack of motivation.
At its core, PDA is about autonomy, safety, and nervous system regulation. When autonomy feels threatened, the body responds. What can look like avoidance, resistance, or shutdown from the outside is often a protective response on the inside.

PDA was first identified in the UK in the 1980s by Elizabeth Newson. In recent years, awareness has grown in the US and Canada, particularly since the establishment of PDA North America in 2020.

PDA Peer Support Group

I facilitate a peer support group for PDA adults through PDA North America. It's a space to connect with others who actually get it, no explaining required. Topics have included things like family estrangement, masking, and the everyday realities of navigating a demand-averse nervous system.

Support Group for PDA Adults meets virtually, monthly on the 2nd Tuesday from: 7:30 pm - 9:00 pm EST

Participation is always opt-in. There's no round-robin sharing and pass is always available. You show up as much or as little as feels right that day.

Important: This is not the right group for parents or partners of PDAers.

Power Differentials in PDA

Most writing on power and PDA assumes one shape: an adult with authority, a child or client with less. This piece names four dynamics adult PDA life actually holds: two PDAers equalising against each other, PDA adults holding power over others, financial and institutional power that can't be equalised at all, and what equalising looks like once you're grown. With strategies for each.

Family Systems and Estrangement in PDA

Nearly a quarter of PDA adults report family estrangement, yet almost nothing is written for PDA adults about their own experience of the families they grew up in. This piece traces why ordinary family expectations land as threats for a PDA nervous system, what the misdiagnosis years leave behind, how estrangement actually unfolds (rarely as one clean break), and why choosing distance can be self-preservation, not failure.

What is Pain Masking?

Most PDA masking discussion centers on hiding autistic traits, but there's a second, less-named kind: masking pain itself. For a PDA nervous system, showing pain invites intervention, and intervention reads as a demand, so the body learns to suppress pain signals as instinct, not choice. This piece traces how that shows up from childhood on, why it makes doctor's appointments especially fraught, and what real support looks like when someone's crash comes days after the actual injury.

PDA & The Workplace

The standard workplace, rigid schedules, open-plan noise, hierarchy-based instructions, wasn't built for a PDA nervous system, and even a paycheck can register as a demand. This piece translates the behaviors that get labeled "difficult" or "unreliable" into what's actually happening underneath, then covers finding a better-fit role, adjustments worth requesting, alternatives to traditional employment, and how to catch PDA burnout before it takes you out entirely.

PDA & Executive Functioning Strategies

Executive functioning tools like checklists and reminders are built to supply structure from the outside, but for a PDA nervous system, outside structure can register as control, and control reads as threat. This piece breaks down what's really happening when help itself becomes a demand, and offers PDA-informed strategies, plus real conversation scripts, for supporting someone (or yourself) without triggering the very shutdown you're trying to prevent.
