Autism and Anxiety: Why They Often Co-Occur
In short: Autism and anxiety often go together because of overlapping brain wiring, sensory overload, and social communication differences. This can make daily life harder, but with the right strategies and support from a BCBA-led team, families can help reduce anxiety and improve well-being. Get ABA Therapy is a free service that matches families with vetted providers who understand these connections.
Key takeaways
- Up to 40-50% of autistic individuals also experience clinically significant anxiety, much higher than in the general population.
- Shared neurological factors, like differences in the amygdala and prefrontal cortex, contribute to both conditions.
- Sensory sensitivities and social communication challenges are major triggers for anxiety in autism.
- ABA therapy, led by a BCBA, can help by teaching coping skills and reducing anxiety triggers.
Understanding the Link Between Autism and Anxiety
If you or a loved one is autistic, you may have noticed that anxiety often comes along for the ride. Research shows that up to 40% to 50% of autistic individuals experience clinically significant anxiety at some point in their lives, compared to about 10% in the general population. This is not a coincidence. There are real, underlying reasons why autism and anxiety so frequently co-occur, from how the brain processes information to the everyday challenges of navigating a world not built for neurodivergent minds.
Understanding this connection is the first step toward finding effective support. Whether you are a parent, a caregiver, or an autistic adult, knowing what drives the anxiety can help you choose the right strategies and therapies. And if you are looking for professional help, services like Get ABA Therapy can connect you with vetted, BCBA-led providers who specialize in both autism and anxiety.

Why Do Autism and Anxiety Co-Occur?
Shared Brain Wiring
The brain structures involved in processing emotions, especially the amygdala and prefrontal cortex, work differently in many autistic individuals. The amygdala, which helps detect threats and triggers fear responses, can be overactive or have altered connectivity in autism. At the same time, the prefrontal cortex, which helps regulate those emotions, may not communicate as efficiently. This imbalance can make it harder to calm down after a stressful event, leading to chronic anxiety.
Sensory Sensitivities
Many autistic people experience sensory sensitivities, meaning they are either hypersensitive (over-responsive) or hyposensitive (under-responsive) to sounds, lights, textures, smells, or movements. Imagine walking into a grocery store where the fluorescent lights buzz loudly, the air smells like bleach and produce, and the background music is jarring. For someone with hypersensitivity, this can feel overwhelming and even painful. The constant vigilance needed to avoid or cope with these sensory triggers can build anxiety over time.
Social Communication Challenges
Navigating social situations can be exhausting and confusing for many autistic individuals. Difficulty reading facial expressions, understanding sarcasm, or knowing when to speak can lead to misunderstandings and rejection. The fear of making a social mistake or being judged can cause anticipatory anxiety, making social events a source of dread rather than enjoyment. This is especially common in school, work, and community settings.
Routine Disruptions and Uncertainty
Autistic individuals often thrive on routine and predictability. When a schedule changes unexpectedly, or when faced with an ambiguous situation, anxiety can spike. The need for sameness is a core feature of autism, and any deviation can feel like a threat. This is why transitions, like starting a new school or moving to a new home, can be particularly anxiety-provoking.
How Anxiety Looks Different in Autism
Anxiety in autistic people may not always look like the classic signs of worry or panic. Instead, it can show up as:
- Increased stimming (repetitive movements like hand-flapping or rocking) to self-soothe.
- Meltdowns or shutdowns that are triggered by anxiety buildup, not just sensory overload.
- Refusal to try new things or extreme avoidance of certain places or activities.
- Physical complaints like stomachaches or headaches without a clear medical cause.
- Sleep problems that worsen during anxious periods.
Recognizing these signs is crucial because anxiety in autism is often missed or misattributed to the autism itself. A child who refuses to go to school may be labeled as "noncompliant" when they are actually terrified of a specific social or sensory trigger.

What Can Help: Practical Strategies and Therapies
ABA Therapy for Anxiety
Applied behavior analysis (ABA) therapy, led by a Board Certified Behavior Analyst (BCBA), is one of the most evidence-based approaches for supporting autistic individuals. While ABA is often associated with teaching skills and reducing challenging behaviors, it is also highly effective for managing anxiety. A BCBA can:
- Identify anxiety triggers through functional behavior assessments.
- Teach coping skills like deep breathing, requesting a break, or using a visual schedule.
- Gradually expose the individual to anxiety-provoking situations in a safe, controlled way (desensitization).
- Build communication skills so the person can express their feelings and needs.
Because ABA is individualized, the strategies are tailored to the person's unique sensory profile, communication style, and interests. This makes it a powerful tool for reducing anxiety in autism.
Other Helpful Approaches
- Cognitive Behavioral Therapy (CBT) adapted for autistic individuals can help reframe anxious thoughts.
- Sensory integration therapy with an occupational therapist can reduce sensory-driven anxiety.
- Mindfulness and relaxation techniques can be taught in a concrete, visual way.
- Social skills groups that are neurodiversity-affirming can reduce social anxiety.
Costs, Insurance, and Getting Started
ABA therapy is widely covered by insurance plans, including many Medicaid programs. In states like California, Texas, Florida, and New York, Medicaid typically covers ABA for autism when prescribed by a doctor. Private insurance plans are also required to cover ABA in most states due to autism insurance mandates. However, coverage for anxiety specifically may vary, so it is important to check with your provider.
If cost is a concern, Get ABA Therapy is a free service that helps families find vetted, BCBA-led providers who accept their insurance. You simply fill out a short form, and the team matches you with options in your area. This can save you time and ensure you get quality care without the financial burden of paying out of pocket.
Common Mistakes to Avoid
- Ignoring anxiety as just a part of autism. Anxiety is treatable and should not be dismissed.
- Using punishment for anxiety-driven behaviors. This can increase fear and worsen anxiety.
- Pushing too hard too fast. Gradual exposure is key; forcing a child into a scary situation can backfire.
- Neglecting sensory needs. Always consider sensory triggers first when addressing anxiety.
- Not seeking professional help. A BCBA or therapist can provide strategies that families alone may not know.
Moving Forward with Hope
Autism and anxiety often go hand in hand, but that does not mean they have to control your life or your child's life. With the right understanding, strategies, and support, it is possible to reduce anxiety and improve quality of life. Whether through ABA therapy, sensory supports, or a combination of approaches, help is available. If you are ready to take the next step, consider reaching out to Get ABA Therapy to get matched with a BCBA-led provider who can create a personalized plan for your family.
