Autism and Anxiety: When to Get More Support and Treatment

When anxiety makes it difficult to sleep, attend school, work, manage everyday tasks, or use skills learned in therapy, it is time to discuss additional support. For an autistic person, that conversation should also consider sensory demands, communication needs, predictability, and what is happening around them. A useful plan may include changes to the environment, adapted therapy, medication, or a combination.

At Forest Psychological Clinic, we begin by asking what is driving the distress. Two people can avoid the same situation for different reasons. Understanding those reasons helps us decide which kind of support is most likely to help.

For additional clinical context, see NICE guidance on autism support and management and the National Institute of Mental Health overview of anxiety.

Start with the reason for the distress

In his discussion of autism and social anxiety, Dr. James Thatcher emphasizes context. Someone who withdraws from a conversation might be afraid of being judged. They might also be overwhelmed by noise, need more processing time, or find the expectations unclear. Several of those experiences can happen together.

Consider a busy lunchroom. One person may dread being embarrassed in front of classmates. Another may find the overlapping voices and smells overwhelming. Someone else may experience both, with the physical discomfort making an already worrying social situation harder to manage. These are possibilities to explore with the person, not diagnoses that can be assigned by watching them from across the room.

Research supports taking this complexity seriously. In a study of 59 autistic young people ages 7 to 17, researchers identified both anxiety that fit familiar diagnostic categories and anxiety presentations that did not fit those categories neatly. Some participants experienced both (Kerns et al., 2014).

Anxiety can also involve persistent worry across everyday situations, specific fears, or panic symptoms. Clinicians consider the person's experience, the circumstances, and the effect on daily life.

Dr. Thatcher also looks at the developmental timeline: what has been present since childhood, what has changed, and when distress became more interfering. A single behavior, such as avoiding eye contact, cannot answer all of those questions. If the diagnostic picture remains unclear, a psychological evaluation may help clarify overlapping concerns and guide recommendations.

When anxiety starts limiting daily life

You do not need to wait until someone can no longer get through the day to ask for help. The National Institute of Mental Health recommends seeking professional support when anxiety starts causing problems at school, work, or in relationships (National Institute of Mental Health [NIMH], 2025).

For Dr. Thatcher, a particularly important signal is that anxiety makes therapy skills difficult to use. A person may understand a coping strategy during an appointment but struggle to access it when worry becomes overwhelming. Repetitive thinking, racing thoughts, and physical distress may take up so much attention that ordinary activities become hard to manage.

He considers a medication consultation especially relevant when anxiety creates this degree of impairment. In his clinical view, medication may become an essential part of care for some people in that situation. The consultation helps determine whether it is appropriate for the individual and how it would fit with their other supports.

Physical symptoms deserve attention too. Anxiety can involve headaches, stomachaches, tension, and sleep difficulties. Those symptoms also have other possible causes, so they should be discussed with a medical provider rather than automatically attributed to anxiety (NIMH, 2025).

It helps to describe the impact specifically: which activities have become difficult, how often this happens, how long recovery takes, and what the person wants to be able to do more comfortably. That gives a clinician more to work with than a description such as “very anxious.”

Make daily life more manageable

In Dr. Thatcher's approach, the environment belongs in the treatment conversation. Clearer expectations, predictable routines, manageable schedules, and attention to sensory demands can make everyday situations more workable. For social connection, he also suggests looking for shared-interest activities where the purpose of being together is clearer.

The details should follow the person's needs. That might mean explaining a change in plans ahead of time, identifying a quieter place to take a break, or allowing time to process a question. Ask which parts of the situation are uncomfortable and which adjustments help.

NICE guidance for autistic children and young people specifically recommends considering communication difficulties, physical discomfort, mental health concerns, lighting and noise, and changes in routine when assessing distress expressed through behavior (National Institute for Health and Care Excellence [NICE], 2021b).

When anxiety and sensory distress overlap, the plan can address both. Dr. Thatcher's explanation connects changes in the environment and daily demands with psychological work on fear. The aim is to help the person participate in a life that works for them.

Adapt anxiety therapy to the person

Cognitive behavioral therapy, or CBT, can help people understand anxiety patterns and practice responding differently to feared situations. For autistic clients, how therapy is delivered matters.

A randomized trial involving 167 autistic children ages 7 to 13 compared standard CBT, CBT adapted for autistic children, and usual care. Both CBT approaches produced higher treatment-response rates than usual care. The adapted program performed better on the main anxiety measure (Wood et al., 2020).

That finding has limits. Participants were verbal children who met the study's cognitive eligibility criteria, including an IQ of approximately 70 or higher. The results cannot establish the same benefit for every age or communication profile. The adapted sessions were also longer and involved parents more, so the study did not isolate which adaptation accounted for the additional benefit.

A separate meta-analysis of 19 randomized trials, involving 833 autistic young people, found that CBT reduced anxiety immediately after treatment. The size of the benefit differed depending on whether clinicians, parents, or young people rated it. Longer-term benefits were not established in the limited follow-up data (Sharma et al., 2021).

In practice, adaptations can include concrete language, visual or written reminders, a clear session structure, breaks, and support to recognize emotions. NICE recommends adapting CBT for autistic children and young people who can engage with that approach, and recommends accessible cognitive and behavioral interventions for autistic adults with co-occurring mental health conditions (NICE, 2021a, 2021b).

Dr. Thatcher's discussion also highlights matching the task to the source of difficulty. Work on fear of judgment might involve a planned, gradual social step. Sensory discomfort calls for attention to the setting and the person's capacity. When both are present, the therapist and client can plan a manageable step with appropriate supports in place.

Where medication can fit

Medication can be part of treatment for an anxiety disorder. The decision should connect a clearly identified concern with a realistic goal and a plan to monitor benefit and side effects. For autistic adults with co-occurring mental health conditions, NICE recommends drawing on guidance for the specific condition while accounting for individual responses and tolerability (NICE, 2021a).

Patrick Lancaster, PMHNP, describes medication and therapy as tools within a broader care plan. In his interview, he emphasizes discussing questions, preferences, and concerns with patients and caregivers. A medication consultation provides room for that discussion; it does not commit someone to taking a prescription. The treatment target is anxiety-related distress and impairment. The person's autistic identity and communication needs should be respected throughout care.

Autism-specific medication evidence needs careful interpretation. A 2022 pilot trial studied mirtazapine for anxiety in 30 autistic children and adolescents over 10 weeks. Improvement favored medication numerically, but the between-group difference did not reach statistical significance (McDougle et al., 2022). A small trial like this cannot establish which medication will work best for an individual.

A 2025 proposal from clinicians at the Lurie Center for Autism also notes that many antidepressant trials in autistic young people measured repetitive behavior, rather than anxiety as the main treatment target. Those results should not be presented as a direct answer about anxiety treatment. The proposal combines clinical consensus with research; it is not a trial proving one medication universally superior (Manter et al., 2025).

For someone considering medication, useful questions include:

• What specific symptoms and everyday difficulties are we trying to improve?

• What evidence supports this option for my age and situation, and is the intended use approved or off-label?

• What changes should we track, how long might benefit take, and when will we review progress?

• Which side effects require a call, and how do we contact the prescriber between visits?

“Off-label” means using an approved medicine in a way that is outside its FDA-approved labeling. A prescriber should explain the evidence, possible benefits, and risks of the proposed use (U.S. Food and Drug Administration, n.d.).

Antidepressants used for anxiety can cause side effects, including stomach upset, headaches, sleep changes, or sexual side effects. Children, teens, and young adults under 25 also require particular attention to possible increases in suicidal thoughts or behavior, especially early in treatment or after dose changes. Discuss new or worsening symptoms promptly with the prescriber and seek immediate help if safety is at risk (NIMH, n.d.).

Agree on what improvement would look like

Patrick recommends looking at change in everyday life and, when useful, keeping a brief journal. With appropriate permission, observations from caregivers, teachers, partners, or other people involved can add context. The person's own experience remains central.

Before treatment starts, choose a few meaningful goals to discuss with your clinician. You might want to spend less time caught in worry, get through a necessary appointment, or use a therapy skill when anxiety rises. Record the situation, what helped, and any unwanted changes. Bring those observations to follow-up visits.

Also ask about comfort, effort, and recovery. Completing an activity tells only part of the story. A useful follow-up conversation includes how the activity felt and what it cost the person to get through it.

NICE recommends regularly reviewing both the benefits and adverse effects of interventions for autistic adults, including any medication-specific monitoring (NICE, 2021a).

Coordinated support at Forest Psychological Clinic

At Forest Psychological Clinic, evaluation findings become part of the clinical chart so the clinicians involved in a person's care can access them. Our clinicians communicate about shared cases. That helps connect what an evaluator has learned with the work happening in therapy or medication management.

Depending on the question, support may begin with individual therapy, diagnostic clarification, or a medication management consultation with Patrick Lancaster, PMHNP. The starting point should reflect the person's concerns and goals.

If anxiety is interfering with daily life for you or your child, contact Forest Psychological Clinic. Share what has become difficult, which supports you have tried, and what you hope will change. We can discuss which service may be an appropriate next step.

Autism and Anxiety Support Options

Autism and anxiety often overlap, but support should be matched to the person rather than the diagnosis alone. A useful plan considers sensory demands, communication needs, routines, physical health, and the situations in which anxiety becomes most disruptive.

When therapy may help

Therapy can help an autistic person understand anxiety, develop practical coping strategies, and prepare for difficult situations without treating autistic traits as problems to eliminate. Forest offers individual therapy and therapy for teens and adolescents.

When medication may be considered

Medication may be discussed when anxiety is persistent, significantly limits daily life, or has not improved enough with environmental and therapeutic support. A medication evaluation should consider current symptoms, previous treatments, side effects, and personal goals.

Common anxiety patterns to discuss

Autistic people can experience several anxiety disorders, including generalized anxiety, separation anxiety, and specific phobias. Heightened anxiety may appear as avoidance, shutdown, distress around change, physical complaints, or sleep problems. For autistic people with an autism spectrum disorder diagnosis, increased anxiety can also reflect sensory overload, communication demands, or uncertainty rather than a single anxiety disorder. A careful evaluation distinguishes these emotional states and considers how autism and anxiety interact in daily life.
