Autism in Women: Why So Many Girls and Women Go Undiagnosed

By Virginia Lindahl, PhD

For many years, autism was primarily understood through research and diagnostic models based largely on boys.

As a result, autism in many girls and women was not recognized until much later in life, sometimes not until adulthood.

Many women describe growing up feeling different but unable to explain why. They may have appeared socially capable on the surface while feeling confused by social interactions, exhausted by the effort required to navigate them, or chronically out of step with their peers.

Some were identified early, but many weren’t.

Clinicians and researchers now recognize that autism in girls and women can sometimes present differently than traditional stereotypes suggest. Because many people still picture autism through a lens shaped largely by how autism has historically been described in boys, these presentations are sometimes overlooked by family members, educators, healthcare providers, and even the women themselves.

Why Autism in Girls and Women Can Be Missed

Part of the challenge is that many characteristics associated with autism aren’t unique to autism. Social anxiety, ADHD, depression, trauma, sensory sensitivities, perfectionism, and personality differences can sometimes create similar outward behaviors.

At the same time, autistic traits in girls and women may not match the stereotypes many people associate with autism. As a result, autism can be mistaken for something else, other conditions may be identified while autism goes unrecognized, or people may simply conclude that they are “different” without understanding why.

This is one reason a comprehensive evaluation is often helpful when someone is wondering whether autism may be part of the picture.

Autism Doesn’t Always Look How People Expect

Many people still associate autism with highly visible social difficulties, obvious repetitive behaviors, or limited emotional awareness. While those presentations certainly exist, autism can also appear in quieter, more internalized, or highly compensated ways.

Girls and women on the spectrum may:

• appear socially interested and motivated

• develop strong observational skills

• imitate peers socially

• mask confusion effectively

• maintain eye contact

• perform well academically

• have intense but socially acceptable interests

• appear emotionally insightful while still struggling socially

Because of this, difficulties are sometimes missed or attributed to other issues such as:

• anxiety

• depression

• ADHD

• perfectionism

• shyness

• emotional sensitivity

• trauma

• “quirkiness”

What’s Masking?

One reason autism in some women is overlooked is masking. Masking refers to consciously or unconsciously hiding autistic traits in order to fit in socially or avoid negative attention.

Women may learn to:

• rehearse conversations mentally

• copy peers’ facial expressions or mannerisms

• study social rules intellectually

• force eye contact

• suppress stimming behaviors

• monitor themselves constantly during interactions

• carefully script social responses

From the outside, someone may appear socially successful.

Internally, however, social interaction may feel effortful, confusing, exhausting, or highly anxiety-provoking. Many women describe feeling as though they are “performing” socially rather than interacting naturally.

Social Difficulties May Be Subtle

Many girls and women with autism are deeply interested in relationships and connection.In fact, many deeply want connection but struggle with:

• interpreting social nuance

• maintaining reciprocal conversations naturally

• understanding unspoken expectations

• navigating group dynamics

• recognizing social dynamics

• managing sensory and emotional overload in social situations

Some develop close one-on-one friendships while struggling more in larger peer groups or socially complex environments. Others feel socially “behind” despite appearing outwardly competent.

Special Interests May Look Different

Special interests in women are sometimes overlooked because they often appear more socially typical.

For example, intense interests may focus on:

• books

• animals

• art

• fictional worlds

• social justice topics

• celebrities

• research-based hobbies

The difference often isn’t the topic itself, but the intensity, depth, emotional significance, or all-consuming quality of the interest.

Emotional Exhaustion and Burnout

Many autistic women spend years compensating socially while trying to appear “normal.” This constant self-monitoring can become deeply exhausting.

Over time, women may experience:

• chronic anxiety

• burnout

• shutdowns

• emotional overwhelm

• depression

• identity confusion

• difficulty maintaining functioning despite appearing successful externally

Some describe feeling as though they can no longer sustain the level of masking they maintained earlier in life.

This is one reason some women aren’t identified until:

• college

• parenthood

• career transitions

• burnout periods

• relationship difficulties

• evaluation for ADHD or anxiety

Autism and ADHD Frequently Co-Occur

Autism commonly overlaps with attention-deficit/hyperactivity disorder.

Women with both autism and ADHD may experience:

• executive functioning difficulties

• emotional dysregulation

• sensory sensitivities

• social exhaustion

• difficulty with transitions

• chronic overwhelm

• inconsistent functioning

In some cases, ADHD symptoms are more readily recognized, while autistic traits remain unidentified for years.

Late Diagnosis Can Bring Mixed Emotions

Receiving an autism diagnosis later in life can feel validating, emotional, confusing, relieving, or grief-provoking.

Many women describe finally understanding:

• why social interaction felt different

• why exhaustion seemed disproportionate

• why relationships were difficult to navigate

• why they felt “out of sync” with peers

• why certain environments felt overwhelming

At the same time, some experience grief over years of misunderstanding, self-criticism, or unsupported struggles.

There’s Not One Single Presentation of Autistic Women

There is no single “female autism profile.” Some autistic women are highly verbal and socially engaged. Others are more visibly autistic. Some have intellectual disabilities. Others are academically or professionally high-achieving. Autism exists across a wide range of presentations, strengths, personalities, and support needs.

The goal of evaluation isn’t to determine whether someone matches a stereotype. The goal is to understand how social communication, sensory experiences, executive functioning, emotional functioning, and developmental history fit together and whether autism helps explain that pattern.

Autism Evaluations in Arlington, VA

I provide comprehensive autism evaluations in Arlington for adolescents and adults, including women whose autistic traits may have been previously overlooked or misunderstood.

Evaluations are designed to better understand patterns of strengths and challenges across social communication, sensory experiences, executive functioning, emotional functioning, and developmental history while helping individuals gain greater clarity and self-understanding.
