PDA: Pathological Demand Avoidance
When everyday expectations become overwhelming
Now is the time to thrive
For some neurodivergent people, even ordinary expectations can create an extraordinary amount of pressure.
Getting ready for school. Answering an email. Going to an appointment. Making a decision. Starting something you actually want to do. Responding to a partner's question. Even being reminded to eat, sleep, or take care of yourself.
For someone experiencing Pathological Demand Avoidance (PDA), which is also called Persistent Drive for Autonomy (and sometimes a variation of the two), a demand may not simply feel inconvenient or unwanted. It can create such an intense internal sense of pressure that the person feels unable to comply, sometimes even when they genuinely want to.
Our PDA therapy is grounded in understanding that anxiety, overwhelm, sensory load, masking, and need for autonomy that can make everyday expectations feel unexpectedly difficult. At TheraThrive, we work with PDA in children, teens, and adults, including people whose PDA has gone unrecognized because it looks very different from stereotypical ideas of refusal or defiance.
Instead of beginning with an assumption we become more curious about what is making things difficult.
What Is PDA?
PDA was originally described as Pathological Demand Avoidance, although many neurodivergent people and clinicians (like us) prefer terms such as Persistent Drive for Autonomy because they better reflect the internal experience rather than describing the person as pathological.
PDA is not currently a separate diagnosis in the DSM-5-TR or ICD-11, and there remains considerable need for research. It is most commonly discussed as a profile associated with autism, although demand-avoidant experiences may occur alongside ADHD and other forms of neurodivergence or neurotypes.
What matters clinically is not simply whether someone avoids demands. Many people avoid things they don't want to do. PDA is not that, and is very different.
A person experiencing PDA may have an intense, sometimes seemingly automatic response to the experience of being required to do something. The pressure itself can become overwhelming.
This may include:
- Direct requests or instructions
- Expectations from parents, teachers, employers, partners, or friends
- School or work responsibilities
- Appointments and scheduled activities
- Social expectations
- Transitions
- Decisions
- Expectations about how someone should behave
- Expectations the person has placed upon themselves
- Activities the person ordinarily enjoys
- Internal needs such as eating, sleeping, showering, or using the bathroom
Sometimes merely knowing that something has to happen changes the experience of doing it.
PDA Is Often About Capacity, Not Motivation
One of the most important shifts in understanding PDA is moving away from: Why won't they do this? and instead move toward: What is happening that makes this feel impossible right now?
At TheraThrive, we often conceptualize PDA as a response to overwhelm and overload.
We view overwhelm as coming from too much emotional input: anxiety, expectations, uncertainty, conflict, social pressure, masking, fear of disappointing someone, or simply too many things requiring attention at once.
Overload may come from too much sensory or cognitive input: noise, lights, people, transitions, decisions, school demands, work responsibilities, social interaction, or the accumulated effort of functioning throughout the day.
For highly sensitive neurodivergent people, those experiences can accumulate.
A seemingly small request can therefore produce a surprisingly large response, and not necessarily because the request itself is large, but instead because the person's nervous system was already carrying too much.
This can be repeats of the same demand, such as reminders, or new demands. In summary: sometimes one more demand is simply one demand too many.
PDA Can Feel Like: I Can't
A person with PDA may desperately want to do something and still find themselves unable to begin.
They might want to attend an appointment and suddenly find themselves unable to leave the house. They may intend to answer a text from someone they care about but feel increasing pressure every time they think about responding.
A teenager may genuinely want to attend school while simultaneously experiencing intense distress every morning when it is time to leave.
An adult may know that a task needs to be completed, understand the consequences of not completing it, and become increasingly anxious about it, yet still feel unable to start.
From the outside, these experiences can look like procrastination, oppositionality, stubbornness, avoidance, or lack of motivation.
Inside, the experience is not likely like that at all.
When something is causing difficulty, it is natural to ask how to make this stop. We also naturally want to understand why something is happening.
PDA may feel like being stuck in a uniquely painful way. For some people, that stuckness can become so profound that it resembles a freeze-like state: the intention to act is present, yet access to action seems temporarily unavailable. This is one reason we believe it is important to understand what is happening neurologically, emotionally, and contextually rather than simply increasing pressure. More pressure would very rarely help someone who is already overwhelmed by pressure.
What Can Trigger PDA?
There isn't always one identifiable trigger.
PDA can emerge from the accumulation of demands across an hour, a day, a week, or much longer. Capacity, which can be impacted by many factors, can also fluctuate considerably.
Masking
A person may successfully meet expectations at school, work, or in social situations while using enormous amounts of energy to do so.
Once that energy is depleted, demands that were manageable earlier may suddenly become intolerable.
This can help explain why a child may appear cooperative throughout the school day and unravel at home—or why an adult may function impressively at work and have very little capacity remaining afterward.
Sensory Overload
Noise, lights, clothing, crowds, movement, physical sensations, other's emotions, hunger, fatigue, and other sensory experiences can consume significant regulatory capacity.
When someone's sensory system is already overloaded, their ability to tolerate additional demands may become much smaller.
Anxiety
Anxiety is often central to PDA.
A request (even an internal one) may create uncertainty, loss of control, fear of failure, fear of judgment, or a sense of being trapped.
Restoring autonomy can therefore become an attempt to restore safety.
Decision Fatigue
Choice is important for autonomy, yet choices can also become demands when someone is depleted.
- What do you want for dinner?
- When should we leave?
- Which assignment will you do first?
- Do you want to go or stay home?
- Eventually, answering a question may feel like too much.
Social and Cultural Expectations
Some demands are never spoken aloud.
- Be productive.
- Be polite.
- Answer your messages.
- Maintain friendships.
- Make eye contact.
- Don't disappoint people.
- Keep up.
- Act your age.
- You should be able to do this.
PDA, Masking, and Burnout
PDA and burnout can overlap considerably, yet at TheraThrive we don't view them as interchangeable.
Both may involve exhaustion, reduced capacity, sensory sensitivity, withdrawal, difficulty initiating tasks, emotional distress, and a much lower tolerance for demands.
However, burnout generally reflects a more sustained depletion of resources. It may develop after prolonged periods of masking, sensory overload, chronic stress, excessive expectations, or continually functioning beyond one's capacity.
PDA can fluctuate much more rapidly. Someone's capacity may change from one situation, or even one moment, to another.
At the same time, prolonged masking and burnout can make PDA responses much more intense. When a person's regulatory resources are depleted, there simply isn't as much capacity available for another expectation, transition, decision, conversation, or request.
This means that an increase in demand avoidance can sometimes be an important signal that a person may be running out of resources.
Rather than increasing demands to restore functioning, we may first need to understand what has depleted their capacity.
PDA Does Not Always Look Like Saying No
Some PDA presentations are obvious. Others are remarkably easy to miss.
A person with PDA might:
- Negotiate
- Debate or explain
- Change the subject
- Use humor
- Delay
- Become distracted
- Withdraw
- Freeze
- Shut down
- Become intensely emotional
- Become angry or panicked
- Leave the situation
- Say they are unable to do something
- Agree to something but then are not able to begin
- Avoid making a decision
- Mask their distress and comply until they reach a place where they feel safe enough to fall apart
Some people externalize their distress. Others internalize it. And some become extremely skilled at appearing capable while experiencing enormous anxiety internally.
This is particularly important when recognizing PDA in teens and adults who have spent years learning how to meet expectations at considerable personal cost.
PDA in Relationships
PDA doesn't occur only in response to parents, teachers, bosses, or authority figures.
It can also impact romantic relationships, friendships, sibling relationships, parenting relationships, families, and other important connections.
Relationships naturally contain expectations.
- Can we talk?
- Please help with this.
- We said we'd go tonight.
- Why haven't you texted me back?
Relationships can be deeply rewarding and also quite complicated, particularly when people within the relationship experience, communicate, or respond to the world differently.
None of these statements are inherently unreasonable, however when a person's nervous system is highly sensitive to pressure, an ordinary relational request can sometimes be experienced with much greater intensity than the other person intended.
This type of situation can create painful misunderstandings.
One person may experience themselves as making an ordinary request of someone they care about, while the other person may experience feeling trapped, pressured, or unable to respond.
Both experiences are real, and gaining insight into PDA in relationships can make a big difference in mutual respect, understanding, and acceptance.
(By the way, relationship therapy with a neurodivergent therapist who knows how to work with PDA can help.)
When PDA Is Misunderstood
Sometimes when PDA is not understood, partners and family members may assign meaning to behavior that wasn't intended.
Avoidance may be interpreted as not caring. Difficulty responding may lead someone to think you might be ignoring them. If you need some space may, it may feel to others as if you are shutting them out. Also, if you express resistance to a plan or activity, others may assume that you want to have control.
Meanwhile, in the background, you may be experiencing PDA, with some accompanying anxiety, sensory overload, exhaustion, fear, shame, or an intense need to regain enough autonomy to regulate.
Over time, misunderstandings like these could start to create difficult cycles. The more one person pushes for connection, reassurance, or some type of communication or action, the more pressured the other person might feel even if they want to connect or reassure, and so forth.
Yet, the more you withdraw or seem to resist, the more hurt or frustrated the other person can become, such that everyone could end up feeling misunderstood.
PDA-Informed Therapy
One thing important to consider is that therapy itself contains demands. You have to attend an appointment on time, you will likely be asked to talk about yourself or answer questions. You may possibly be provided with exercises or strategies to try. Ultimately therapy asks you to work towards changing something.
For someone with PDA, even therapy that is intended to help can inadvertently recreate an experience of pressure. This is why the therapeutic relationship, flexibility, curiosity, and also collaboration matter.
At TheraThrive, we don't believe it is helpful or effective PDA therapy to try to eliminate all of the expectations from someone's life. Nor do we think that anxiety is needed to help determine someone's decisions Instead, we will work together to understand what is driving the PDA response and help you to develop greater access to regulation, communication, self-understanding, and your core sense of choice.
Depending upon the person, PDA therapy may include:
- Playing, sandtray therapy, sensory activities, and/or art
- Identifying patterns and triggers without judgment, including internalized shoulds
- Understanding sensory and emotional needs and also overload
- Recognizing early signs of decreasing capacity and energy depletion
- Exploring anxiety and what the need for autonomy may look or feel like
- Developing language for communicating needs
- Understanding masking and its costs
- Addressing burnout and chronic exhaustion
- Finding ways to approach necessary demands with greater flexibility
- Exploring trauma, when relevant
- Developing accommodations for home, school, work, and/or within relationships
Most importantly, we support you in better understanding your own nervous system and developing ways to recognize, communicate, and support your needs.
Supporting Children and Teens With PDA
Children and teens with PDA may be described as oppositional, controlling, manipulative, or unwilling to follow directions. Those descriptions can profoundly change how a child feels about themself and also how adults respond to them.
If we assume behavior is primarily about defiance, the results may be an increase in structure, consequences, or pressure. Yet when a child's behavior is being driven by anxiety, overwhelm, sensory overload, and/or a loss of felt autonomy, increasing pressure may intensify the very response adults are trying to reduce.
At TheraThrive, we help families become curious about capacity. We explore what happened before the avoidance occurred. We also explore the environment and situations a child has been in, including how much sensory experiences have they had to manage. Learning about and understanding a child's masking is also important part of treatment.
Additional factors, including if a child is hungry, tired, overwhelmed in some way, anxious, or just socially depleted. Perhaps there was an unexpected transition, or a series of transitions. All of these can be seen as demands and taxing on a nervous system. We also look at what is manageable, strengths, and work-arounds to help create strong autonomy. Sometimes the most meaningful change can come from simply understanding why a child has already been trying hard, and how to know when they need to conserve energy.
PDA in Adults
Many adults discover PDA only after years of wondering why seemingly ordinary responsibilities can sometimes feel inexplicably difficult. Adults generally have more autonomy than children, in which case PDA may not be as obvious. Additionally, adults may also have developed more sophisticated ways of structuring their lives to avoid situations that create intolerable pressure.
PDA in adulthood might appear as difficulty with:
- Appointments
- Communication, such as emails and texts
- Household responsibilities
- Work expectations and deadlines
- Decisions
- Maintaining relationships
- Self-care
- Small tasks throughout the day
- Activities that were originally enjoyable and more lately have begun to feel obligatory (this can even occur in game play)
Some adults are quite capable in many areas of their lives, yet may still struggle with PDA.
Recognizing PDA can help adults to understand they can replace years of self-criticism with self-understanding, especially around the conditions under which their brain functions best.
Understanding Changes What We Do
A goal is to create a life in which demands won't continually overwhelm your capacity to meet them, versus creating a life without responsibilities.
This means:
- Changing your communication style.
- Reducing your overall sensory load.
- Allowing for recovery after masking.
- Stimming, as pertinent
- Building more flexibility into your routines.
- Examining unnecessary self-induced pressure
- Learning when choice is helpful and when making a decision would be too much.
- Repairing misunderstandings
- Recognizing burnout before you reach exhaustion.
- And finding ways to preserve autonomy while still navigating the realities of school, work, family, relationships, and daily life.
For many PDA children, teens, and adults, being understood differently can itself be a reduction in pressure. We want to support you (or your child) in learning how to recognize capacity and to develop your container and a greater sense of autonomy.
Understanding PDA can change what happens next. We provide neuroaffirming, PDA-informed therapy for children, teens, adults, and families.
