Overview
PDA Pathological Demand Avoidance is autism profile with extreme anxiety-driven need for control. Demand avoidance is not defiance but nervous system threat response to loss of control. Even simple requests trigger fight-or-flight. Demands accumulate throughout day until meltdown or shutdown. Traditional reward-consequence approaches backfire spectacularly. PDA often starts childhood. Co-occurs with ADHD OCD anxiety. Many misdiagnosed as ODD when root cause is anxiety not defiance. Low-demand approaches focus on collaboration autonomy reducing pressure. Not permissive parenting but trauma-informed support acknowledging nervous system differences. Recovery after meltdowns takes days not hours. PDA Society provides evidence-based guidance though remains controversial in UK clinical practice.
