Autism Masking: Why So Many Autistic Adults Are Hiding in Plain Sight

By Dr. Tyler Gerdin, PsyD, ABPP | Gerdin Psychological Services, Spokane, WA

She's articulate. Makes decent eye contact. Laughs at (almost) the right moments in conversation. She's held down jobs, maintained friendships — at least on the surface — and managed to move through the world without anyone raising a flag.

She's also been quietly exhausted for as long as she can remember. Social interactions that others seem to find effortless require something from her she can't quite name. She goes home and crashes. She's been in therapy for anxiety, depression, maybe a personality disorder. Nobody has ever mentioned autism.

What clinicians are missing is that they're seeing the performance, not the person.

That performance has a name: masking.

What Autism Masking (Camouflaging) Actually Is

Autism masking — also called camouflaging — refers to the conscious and unconscious strategies autistic people use to appear neurotypical. Forcing eye contact. Suppressing the urge to stim. Scripting conversations in advance. Mirroring other people's facial expressions, tone, and body language. Performing "normal" with such precision that nobody looks twice (Hull et al., 2017; Pearson & Rose, 2020).

Critically, masking changes what clinicians see — it does not change the underlying autistic profile. The sensory overwhelm is still there. The social processing differences are still there. The exhaustion of translating every interaction through a second language is still very much there. Masking just buries it under a layer of learned performance that can take decades to build and decades to recognize.

Tony Attwood and colleagues have described three broad patterns in autistic girls and women that illustrate this well. The first is the introverted type — someone who recognizes that social situations are complicated and overwhelming and quietly withdraws. The second is the intrusive extrovert — drawn to social situations despite struggling to read them, often coming across as intense or overbearing, with relationships that end in confusion and hurt feelings she can't quite explain. The third is the camouflaging extrovert — perhaps the most diagnostically elusive — someone who has studied other people so carefully, mimicked their cues so precisely, that she genuinely appears socially fluent. Her family sometimes knows exactly who she's playing. Her clinicians often don't.

Why Autism Masking Is Especially Common in Women and Girls

The research is consistent: autistic females camouflage more than autistic males, more consistently, and well into adulthood (Alaghband-rad et al., 2023; McQuaid et al., 2021). Part of this is developmental. Autistic girls often have greater social motivation than autistic boys — they want connection, they study it, they practice it. But the social rules keep shifting in ways that don't come naturally, and the stakes of getting it wrong feel enormous.

The DSM-5 criteria for autism were largely built on research with males. The stereotypes — hand-flapping, no eye contact, no interest in people, eccentric solitary interests — don't map onto most autistic women and girls. Autistic girls tend to have subtler repetitive behaviors, or they change them earlier so others don’t notice. Their restricted interests often look "typical" (animals, pop culture, a specific fandom, makeup, social justice) — just more intense and narrower than peers would expect. They're often described as shy rather than having poor eye contact. Passive rather than disruptive. Socially immature rather than socially impaired.

At school, an autistic girl often goes along with the crowd, stays quiet, avoids trouble. At home — where the mask comes off — she may be a completely different person: dysregulated, exhausted, in meltdown. Parents describe a child they can't quite reach. Clinicians see someone who seems fine.

The Clinical and Human Cost of Masking

Masking is a survival strategy. It emerges from stigma, from early experiences of exclusion, and from the very reasonable conclusion that hiding is safer than being seen (Pearson & Rose, 2020; Miller et al., 2021). In that sense, it works. But the cost is significant.

Research consistently links high masking with worse mental health outcomes — depression, anxiety, burnout, and elevated rates of suicidal ideation (Miller et al., 2021; Evans et al., 2023). A 2024 study found that autistic adults, particularly women, frequently received prior diagnoses of anxiety, mood disorders, or personality disorders before anyone considered autism — with masking specifically identified as a key driver of that diagnostic shadow (Kentrou et al., 2024).

There's also something more personal at stake. When someone has spent years performing a version of themselves that isn't quite real, the identity cost accumulates quietly. Many autistic adults describe not knowing who they actually are underneath the mask — what they genuinely enjoy, what they actually find painful, what they need. That's not a small thing to reckon with.

And for autistic women specifically, the stakes extend further. Research suggests autistic girls and women experience significantly elevated rates of sexual victimization compared to neurotypical peers — in part because difficulty reading social cues makes dangerous situations harder to recognize, and in part because asking for help feels complicated, overwhelming, and — for many who have internalized the message that needing help means something is wrong with them — impossible (Bargiela et al., 2016).

What a Good Autism Evaluation Does Differently

Many clinicians do not complete autism assessments with masking in mind. They look for what's visible. For a practiced masker, what's visible may tell you very little.

A thorough evaluation for autism in adults — particularly women and gender-diverse individuals — has to go beneath the surface. That means asking about the experience of social interactions, not just the behavior. Not "do you make eye contact?" but "what does eye contact feel like for you?" Not "do you have friends?" but "what does it cost you to maintain them?" It means asking specifically about sensory sensitivities that may have been suppressed or internalized. It means understanding that an autistic woman's intense interest in something like true crime, K-pop, or horses is no less diagnostically meaningful than an interest in train schedules — it just looks more familiar.

It also means taking the history seriously. A childhood of being described as "quirky," "too sensitive," "a people pleaser," or "always in her own world" is clinically relevant. So is the pattern of adult burnout that nobody can quite explain.

The DSM criteria apply to what someone experiences currently or by history — which means a skilled evaluator is partly doing archaeology, working backward through years of compensatory behavior to find the underlying profile that was always there.

Getting the Right Answer: Autism Assessment for Adults

If any of this sounds familiar — if you've spent years wondering why everything feels harder than it seems to for everyone else, why social situations drain you in a way that's hard to explain, why you've never quite felt like yourself in the world — a comprehensive evaluation by someone who understands complex and masked presentations is worth pursuing.

Frequently Asked Questions About Autism Masking

What is autism masking? Masking — also called camouflaging — is the set of conscious and unconscious strategies autistic people use to appear neurotypical: forcing eye contact, suppressing the urge to stim, scripting conversations in advance, and mirroring other people's expressions and tone. It changes what other people see, but not the underlying autistic profile. The sensory overwhelm, social processing differences, and exhaustion are all still there — just buried under a layer of practiced performance.

What are the signs of autism in adult women? In women, autism often looks subtler than the stereotype: passing as "shy" rather than socially impaired, intense but familiar-looking interests (animals, a fandom, true crime, social justice), quieter repetitive behaviors, and a deep, hard-to-explain exhaustion after socializing. Many appear socially fluent in public and only unmask — dysregulated, drained, sometimes in meltdown — once they're home.

Why is autism so often missed in girls and women? The diagnostic criteria were largely built on research with boys, so the classic markers don't map onto most autistic women. Autistic girls also tend to have greater social motivation, study and rehearse social rules, and camouflage more consistently well into adulthood — which makes the underlying profile genuinely hard to see, even for experienced clinicians.

Can you be diagnosed with autism as an adult? Yes. Autism is lifelong, but many people — especially women — aren't identified until adulthood, often after years of being treated for anxiety, depression, or a personality disorder. Because the diagnostic criteria apply to what someone experiences currently or by history, a skilled evaluator works backward through years of compensatory behavior to find the profile that was there all along.

Is it autism, or is it anxiety or a personality disorder? It's frequently mistaken for all of them. Research shows autistic adults, particularly women, often receive prior diagnoses of anxiety, mood, or personality disorders before anyone considers autism — with masking identified as a key driver of that "diagnostic shadow." A masking-aware evaluation is specifically designed to tell the difference.

Why am I so exhausted after socializing? For someone who masks, every interaction is translated through a kind of second language — managing eye contact, tone, facial expression, and scripts in real time — and that constant performance is depleting in a way that's hard to name. The crash afterward, and the longer pattern of unexplained burnout, is one of the most common experiences autistic adults describe.

What does an autism evaluation for adults involve, and where can I get one in Spokane? A good evaluation goes beneath the surface — asking what social interaction feels like and what it costs you, not just whether you do it; taking sensory experiences and childhood history seriously; and recognizing masked presentations for what they are.
