Autism and Co-occurring Anxiety

Anxiety is one of the most common experiences among autistic people. Research suggests that a large proportion of autistic children and adults experience significant anxiety, far more than in the general population. This can include generalized worry, social anxiety, specific phobias, panic, and obsessive-compulsive patterns. Anxiety in autistic people often has distinct triggers, such as uncertainty, sensory overload, changes in routine, and the effort of navigating social expectations. It may also look different from anxiety in non-autistic people. Recognizing and treating anxiety in an autism-informed way can make a significant difference to quality of life.

What Anxiety Can Look Like in Autistic People

• Intense distress when plans change unexpectedly.
• Worry about social situations, being misunderstood, or making mistakes.
• Anxiety in noisy, bright, or crowded places, often linked with sensory overload.
• Increased need for routines, sameness, or control.
• More stimming, pacing, or repetitive behaviours under stress.
• Avoiding new places, people, or activities.
• Meltdowns or shutdowns when anxiety builds.
• Physical symptoms, such as stomach aches, headaches, or sleep problems.
• Difficulty identifying anxiety as an emotion, sometimes linked with alexithymia.

Why It Happens

Several factors contribute to high rates of anxiety in autism. Many autistic people have a strong need for predictability, so uncertainty can feel especially threatening. Sensory sensitivities mean that ordinary environments can be overwhelming and hard to escape. Social situations often require effortful interpretation of unwritten rules, and past experiences of being misunderstood, bullied, or excluded can increase fear. Masking, or hiding autistic traits to fit in, is exhausting and associated with higher anxiety and depression. Biological factors, including differences in how the brain processes threat and uncertainty, may also play a role.

Anxiety and autistic traits can be hard to separate. For example, a preference for routine is part of autism, but rigid insistence on routine can increase when anxiety is high. Social anxiety may co-occur with autistic social differences. A clinician experienced in autism can help distinguish what is anxiety and what is an autistic way of being, so that support targets distress rather than identity. Ongoing anxiety and overload can also contribute to autistic burnout.

Anxiety in autistic children may show up mainly through behaviour, such as refusing to go to school, meltdowns, or clinging to routines. Parents may need to look beneath the behaviour to identify what is causing distress. Visual schedules, advance notice of changes, and quiet spaces can help children feel safer.

Autistic adults sometimes find that anxiety eases once they understand their autism and adjust their lives to fit their needs. Reducing unnecessary demands, building in recovery time, and spending time with people who accept them can lower the baseline level of threat.

What It Is Not

• Not an inevitable part of autism. Anxiety is common but treatable.
• Not a reason to eliminate autistic traits. Support should reduce distress, not force someone to act non-autistic.
• Not always visible. Many autistic people hide anxiety through masking.
• Not something standard treatment always fits without adaptation.

How It Is Assessed and Treated

Assessment should consider autistic communication, sensory needs, and how anxiety shows up, and may include input from family. Cognitive behavioural therapy adapted for autistic people has good evidence. Adaptations include using visual supports, concrete language, building on special interests, involving parents or partners, and paying attention to sensory needs. Gradual exposure can help with specific fears when done collaboratively and at a comfortable pace. Environmental changes, such as predictable routines, advance notice of changes, and sensory accommodations, reduce anxiety triggers. Medication may be considered for some people. Neurodiversity-affirming therapy supports self-understanding and reduces the pressure to mask.
