If Your Exhaustion is Debilitating, Disabling, and Intermittent, it Might be Autistic Burnout
An overview of the signs of autistic burnout, according to the most recent and thorough research available
Are you wondering whether you are in autistic burnout? It’s not an unrealistic worry, given how common this condition is in the autistic community. In fact, a study by Mantzalas et al (2024) estimated that up to 69% of autistic people have experienced autistic burnout at least once.
I see it frequently in my therapy practice, where the odds are good that my autistic clients are finding their ability to cope is slipping. That’s why I’m writing a series on what clinical research—which is slowly catching up to my clients’ lived experiences—is telling us about autistic burnout. In this post, I will explore the signs of this condition. In future posts, I’ll share its causes and current recommendations for recovery.
The difference between autistic burnout and occupational burnout
First, let’s define our terms. Normally, when we talk about burnout, we are referring to occupational burnout. Although autistic burnout has some overlap with this more commonly discussed syndrome, there are key differences.
Occupational burnout is defined by the 11th Revision of the International Classification of Diseases (the World Health Organization’s guide for diagnosing health conditions) like this:
Burn-out is a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed. It is characterized by three dimensions:
feelings of energy depletion or exhaustion;
increased mental distance from one’s job, or feelings of negativism or cynicism related to one's job; and
reduced professional efficacy.
Ali et al, authors of an excellent systematic review (i.e., a summary of all research to date of a specific topic) on autistic burnout define the condition like this:
Our findings suggest that burnout, as experienced by these autistic people, consisted of debilitating exhaustion and increased disability, which could be chronic with intermittent crises.
The Signs of Autistic Burnout
Here are the signs of autistic burnout, according to the 2025 systematic review by Ali et al that I just mentioned:
1. You are exhausted
It will probably come as no shock that deep fatigue is a defining characteristic of autistic burnout. You are tired, pure and simple.
2. You have lost certain abilities
You feel “more autistic” than normal, and more connected to the realities of being disabled. What you used to do with more ease now feels incredibly challenging.
3. You find it harder to process sensory stimulus
Your sympathetic nervous system is producing more fight, flight, or fight responses when you are subjected to challenging sensory stimulus. So if someone spritzes a perfume that nauseates you, you’re more likely to have the following reactions: “I want to yell at this person for spritzing this perfume” (fight); “I must leave this room because that person spritzed some perfume” (flight); “I’m dissociating because that perfume was spritzed” (freeze).
4. You find it harder to process emotions
Again, your system is more likely to respond to emotionally difficult situations with fight, flight, or freeze responses. You find relating to people more stressful, and conflict more devastating. You feel sensitive and raw.
5. You have reduced executive function
Planning, thinking, speaking, remembering—all of the “work” our frontal cortexes are designed to do—is much more difficult.
6. You find it harder to do everyday tasks
Just existing, just keeping up with everyday responsibilities is a big ask. The items on your to-do list pile up, and you feel helpless.
7. You have felt this way for at least 3 months, and maybe you’ve felt this way before
Autistic burnout is more likely to be chronic, i.e., a condition that does not present as “one and done” or last for brief periods. It is more likely to recur throughout your life. You have times of crisis when, for months or years on end, life is much more difficult. Seasons of burnout come and go.
