Do you try to avoid tasks or demands expected of you, or do you feel pressure or anxiety because of them? When this happens constantly rather than occasionally, it may relate to a kind of autism spectrum called Pathological Demand Avoidance (PDA). PDA is often misunderstood by clinicians, employers, and support services due to its different profile characteristics from other autism profiles.
In 1980, Professor Elizabeth Newson at the University of Nottingham first described PDA. Recognition of the profile in adults remains inconsistent in the UK, with the challenges adults face in obtaining a diagnosis and the specialist support pathways available.
What is PDA Autism in Adults? Understanding the Profile
Pathological Demand Avoidance (PDA) describes a pattern of autistic experience in which demand avoidance is not occasional but pervasive and present across all settings, throughout the day, and significantly impacts daily life.
We all avoid things that we don’t want to do sometimes. PDA differs because the avoidance is persistent and often outside the person’s control. When a demand or instruction lands on someone with Pathological Demand Avoidance, many individuals with PDA may experience demands as threatening or overwhelming and avoids it as a defensive reaction. Generally, the avoidance is driven by a stress and anxiety response rooted in a nervous system that perceives demands as threatening.
In the UK, PDA is recognised as a type of autism, unlike the DSM-5 and ICD-11 (medical manuals used around the world). The PDA Society, which is the main UK charity focused on PDA, along with more and more research studies, believes that PDA is part of the autism spectrum.
Common Symptoms of PDA in Adults
Adults with PDA develop sophisticated strategies to mask demand avoidance, such as being present as charming, articulate, and engaging in short bursts, making it harder to identify the autism profile.
- Pervasive Avoidance of Demand: Avoiding emails, phone calls, work tasks, responsibilities, or even things they want to accomplish.
- Sophisticated Avoidance Strategy: A person with PDA will not outright refuse, but will use distractions such as humour, redirecting conversations, and providing elaborate justifications, etc.
- Demand Avoidance Extending to Self-Imposed Goals: When a person’s favourite task or things they enjoy doing turn into an obligation that can trigger avoidance in a person with PDA.
- Intolerance of Uncertainty: When a person’s intolerance of uncertainty magnifies, such as not knowing what to do if certain tasks or demands are made.
- Sensory Processing Differences: Environmental changes, noises, and sudden lights can make demands feel more stressful and make an adult with Pathological Demand Avoidance feel dizzy, nauseated, or have brain fog.
- Social Masking and Performance: Appearing as socially confident in short conversations while experiencing intense internal distress, especially women.
- Engagement with Roleplay and Fantasy: Roleplay and fiction can help individuals feel safer and less stressed while dealing with real-life problems or demands.
- Identity and Control: A strong need for control or independence. Strict rules, demands, or unexpected situations can feel stressful or difficult to manage.
Why PDA is Often Overlooked or Misdiagnosed in Adults
Adults with a PDA profile are experiencing what the PDA Society has described as a mental health crisis, one that is substantially linked to years of misunderstanding, inappropriate support strategies, and systemic barriers.
This is the most significant recent dataset on PDA and the mental health briefing 2023 in the UK:
- 84% of PDA adults reported experiencing suicidal thoughts
- 82% of PDA adults have experienced severe anxiety in the previous year
- 71% reported that a poor understanding of PDA created barriers to support
- Only 20 individuals found CBT-style approaches helpful without adaptations
If you or someone you know is experiencing severe emotional distress, support is available through a GP, NHS 111, or mental health services.
Navigating the UK Adult Diagnostic Pathway
The UK Adult Diagnosis Pathway: Getting an autism (and PDA) diagnosis as an adult
- See your GP
- GP referral
- Triage and screening
- Assessment appointment
- Outcome and diagnostic report
There are three routes to the assessment of Pathological Demand Avoidance:
- NHS Local: GP refers you to your local autism assessment service. It is free, but it takes years sometimes for your assessment to be completed.
- Right to Choose: NHS-funded but with a private provider of your choice. Start with GP. Takes time, but ICB funding varies.
- Private: Pay for a private assessment. No GP referral needed. This is a much faster process, and you don’t have to wait, but all the expenses are borne by you.
Managing Daily Life: Practical Strategies for PDA Adults
Many adults with PDA encounter advice that can feel unrealistic or difficult to apply in everyday life. However, many adults find that generic advice can be difficult to apply consistently in real-life situations. Rather than trying harder, reduce demands and build skills.
Here are some practical strategies for Pathological Demand Avoidance:
- Make choices: Task, responsibilities, and demands convert these into choices
- Shrink Demands: make a list of tasks that feel overwhelming or obligatory, and break it into small choices or make it optional.
- Self-care is not an obligation: do things as you allow yourself, not something you must do.
- Adjust work and employment: change work environment (work in a hybrid or remote environment), take flexible deadlines, avoid unnecessary team events, consider self-employment
- Manage your PDA burnout: when demands pile up and anxiety rises, the brain’s nervous system crashes, resulting in burnout. Build flexible routines, remove obligation rather than pausing them.
Accessing UK Support: PIP, Access to Work, and Social Care
Accessing PDA support in the UK for people with an autism profile can make their lives more independent, confident, and financially stable.
Apply for Personal Independence Payment (PIP)
PIP (Personal Independence Payment) is for people with conditions such as autism or PDA, who are facing everyday difficulties living.
- Apply for a claim at the Department for Work and Pensions (DWP)
- Fill the form, which assesses everyday activities, social interaction, and independent travel, etc.
- Supporting evidence from healthcare professionals can strengthen the application.
Explore the Access to Work Scheme
Access to Work is a government-funded scheme, which you can apply for from your computer or smartphone online. For autistic adults who are employed or preparing for work, Access to Work provides workplace adjustments, travel support, or job coaching.
Request a Social Care Needs Assessment
Local healthcare services or councils can provide support. First, an assessment will look into your daily challenges to determine the proper care needs to improve your quality of life. Support may include home care, respite services, or community access assistance.
