Autism in Girls: Why It Can Be Overlooked
Learn how autism may present differently in girls, how camouflaging can make autistic characteristics harder to recognize, and what parents can look for in children and teens. While the core diagnostic criteria for autism are the same for boys and girls, the ways autistic characteristics are expressed and recognized may vary.

Historically, autism has been identified and diagnosed more frequently in males than in females. One contributing factor may be that early autism research and clinical understanding were based largely on male-dominated samples. Consequently, the characteristics professionals learned to recognize may not have captured the full range of autistic presentations.
Research increasingly highlights the importance of recognizing autistic girls and women whose characteristics may be less obvious, may be interpreted differently, or may be camouflaged through learned strategies. Some girls and women are therefore overlooked, misidentified, or diagnosed later in life, potentially delaying access to appropriate support.
However, less readily recognized presentations of autism are not exclusive to girls. Boys with similar patterns of autistic characteristics, including those with strong language and cognitive abilities, may also be overlooked or misidentified when their characteristics do not match commonly recognized stereotypes of autism. The same diagnostic criteria apply to boys and girls, but the ways autistic characteristics are expressed, compensated for, or recognized may vary from one individual to another.
Although research into autism in females has expanded, further investigation is needed to understand the full range of autistic presentations and improve recognition and assessment across individuals.
Autism Can Look Different
Some autistic characteristics are readily observable, while others may be less apparent because of how they are experienced, expressed, or camouflaged. A child’s outward behaviour does not always reveal the full extent of their differences, the effort involved in navigating everyday situations, or the support they may need.
Research has drawn particular attention to girls and women whose autistic characteristics may be less readily recognized, especially when they have strong language or cognitive abilities or use strategies to navigate social situations. However, boys with the same presentation of autistic characteristics can also be overlooked. A child of any gender may communicate clearly, perform well academically, or appear to manage social situations while experiencing difficulties that are not immediately apparent to others.
Adults may notice children whose behaviours are more visible, while overlooking children whose differences are interpreted as shyness, daydreaming, disorganization, emotional sensitivity, or anxiety. These interpretations may mean that autism is never considered and the child is not referred for an assessment. Even when an assessment takes place, less-visible autistic characteristics may not be recognized, potentially leading to a missed diagnosis or an alternative diagnosis that does not fully explain the child’s developmental profile and support needs. As a result, the child may not receive the appropriate support.
Autism is characterized by differences in social communication and social interaction, together with restricted or repetitive patterns of behaviour, interests, or activities. Both diagnostic areas must be considered when evaluating whether a person meets the criteria for autism. These characteristics can present in different ways and to varying degrees.
Although the diagnostic criteria are the same for girls and boys, individual characteristics may be expressed, experienced, or recognized differently.
Social Communication and Social Interaction
Social communication refers to how a person understands and uses verbal and nonverbal communication to interact, participate, play, and communicate with others in different situations.
Social interaction refers to the back-and-forth exchange between people. It also involves how a person engages with peers, participates in imaginative play, and develops and maintains friendships.
Language impairment
Some autistic children also have language difficulties. When applicable, the diagnosis may include the specifier with accompanying language impairment. However, autism can occur with or without accompanying language impairment.
Restricted Interests and Routines
Some autistic children have highly focused interests. The topics themselves may appear typical for their age, but the intensity, depth of focus, or rigidity surrounding them may be more pronounced.
Some children also have a strong preference for familiarity, predictability, and routines. Unexpected changes may cause significant distress, particularly when the child has difficulty shifting attention or adapting to a new situation.
Repetitive Movements, Speech, or Use of Objects
Some children repeat movements, words, phrases, or actions, or use objects in repetitive ways.
Examples include lining up toys, flapping their hands, repeating words or phrases (echolalia), or using language in an unusual or highly individual way.
Sensory Differences
Sensory differences involve how a person experiences and responds to sensory information.
Some children may be particularly sensitive to sounds, textures, light, pain, or temperature. Others may show reduced responses to certain sensations or have an unusually strong interest in particular sensory experiences.
Levels of Support
The DSM-5-TR describes three levels of support for autism: Level 1, requiring support; Level 2, requiring substantial support; and Level 3, requiring very substantial support. Support levels are considered separately for social communication and restricted or repetitive patterns of behaviour. An individual’s support needs may vary across areas and change over time.
How Can Autistic Characteristics Be Expressed?
Some autistic characteristics are externally expressed, meaning they are readily observable to others. Other characteristics may be experienced internally and may not be readily apparent to others.
This distinction is particularly important when considering autistic children and adolescents with strong language skills and cognitive abilities who may appear to manage well in everyday situations. Their abilities can make their underlying differences and support needs less obvious, particularly when they compensate for or camouflage their characteristics.
Although more observable characteristics have historically been more readily recognized in boys, while less visible or camouflaged characteristics may be more easily overlooked in girls, these patterns are not exclusive to either gender. Autistic children and adolescents of any gender may show a combination of externally expressed and less visible characteristics.
The difficulty is recognizing how autistic characteristics may be expressed, compensated for, or hidden in different individuals.
For example, educators may more readily notice students whose behaviours are highly visible, such as those who frequently move around, engage in repetitive movements, or show distress when routines change. Other students may appear quiet, shy, distracted, or emotionally sensitive, making their underlying experiences or support needs less apparent. This may be particularly relevant for children and adolescents who have strong language skills, perform well academically, or work hard to meet social expectations.
The important distinction is between what others can readily observe and what a child may be experiencing internally or working hard to conceal or compensate for. Understanding these differences can help parents, educators, and professionals recognize autistic characteristics that might otherwise be overlooked.
Externalized Characteristics: What Others Observe
Externalized characteristics are actions that are visible from the outside and can be observed by others.
Examples include:
- Sensory differences: Seeking particular sensory experiences, such as closely examining objects, or avoiding certain sensations, such as covering the ears in response to loud noises.
- Insistence on sameness: Becoming distressed when routines change, familiar activities end unexpectedly, or things do not happen as anticipated
- Repetitive movements: Rocking, finger posturing, or other repetitive movements that may help the child respond to excitement, anxiety, or sensory experiences.
- Repetitive use of objects: Spinning, lining up, sorting, or grouping toys according to a particular pattern or rule.
- Restricted interests: Intense interest in a particular subject, object, or activity, or developing extensive knowledge about a specialized, more uncommon subject.
These characteristics may be easier for parents and teachers to notice, although their meaning must be considered within the child’s broader developmental picture.
Internal Experiences and Camouflaging
Some autistic characteristics may be less obvious to other people because they happen more on the inside. A child may work hard to navigate social situations, manage sensory discomfort, or meet expectations without showing the extent of the effort involved.
Camouflaging refers to strategies autistic people may use to compensate for, mask, or minimize the visible expression of their autistic characteristics. These strategies may help them navigate social situations or feel more accepted by others, but they can also require considerable effort and contribute to exhaustion or emotional distress.
Camouflaging is often described in terms of three strategies:
- Compensation: Using strategies to navigate social difficulties, such as rehearsing conversations or preparing scripts for social situations.
- Masking: Hiding or suppressing autistic characteristics or mannerisms, such as consciously monitoring facial expressions or body language.
- Assimilation: Trying to fit in with others by imitating their behaviour, hiding self-regulatory movements (stimming), or downplaying personal interests.
These strategies can make a child’s differences less apparent. However, appearing socially competent does not necessarily mean that social interactions are easy or effortless.
Examples of Internalized Characteristics
The following examples describe experiences or strategies that may occur in some autistic people. They are not diagnostic indicators in isolation, and some may also occur in people who are not autistic.
- Sensory Differences: Planning around a sensory load without naming it as a sensory issue. For example, avoiding noisy restaurants with big crowds.
- Shutdowns: When sensory input, social demands, emotional stress, or other demands become overwhelming, some autistic people may withdraw, respond less to others, have difficulty speaking, cry, or seek a quiet or dark space. These responses may be less visible to others than outward expressions of distress.
- Social Communication and Social Interaction: Some children use scripted conversations, imitate facial expressions, or consciously work out social expectations to navigate interactions. They may appear socially competent while finding these interactions effortful or exhausting.
- Repetitive Speech and Internal Repetition: While repetitive speech may be externally expressed through repeating words, phrases, or dialogue, less visible forms of repetition may include mentally rehearsing familiar phrases, repeatedly replaying conversations, or internally repeating words or dialogue. These internal experiences may not be apparent to others.
- Insistence on Sameness: Some individuals may rely on detailed plans, familiar routines, or rigid personal rules to create predictability and manage uncertainty. Perfectionism may occur as a coping strategy but is not, by itself, a diagnostic characteristic of autism.
- Emotional Reciprocity: Experiencing emotions intensely or finding it difficult to identify, communicate, or regulate feelings.
- Restricted Interests: Developing deep interests in topics that may appear socially typical such as animals, nature, literature, fantasy worlds, fiction, psychology, true crime. The intensity and focus may be less obvious because the topic itself is familiar and socially accepted.
Some autistic people show a combination of more visible and less apparent characteristics. Their presentation may also vary across situations and change as they grow older, develop coping strategies, or encounter different demands. Some characteristics may be noticeable to others, while others may be masked or experienced internally.
For example:
- Different characteristics in different areas: A child may show visible distress when overwhelmed while also working hard to follow social expectations or mask sensory discomfort.
- Changes over time: A child whose repetitive movements or difficulty with transitions were noticeable when younger may later learn to suppress these behaviours or use other strategies to manage uncertainty.
- Differences across settings: A child may appear to manage well at school but experience significant exhaustion or distress at home after navigating social, sensory, or academic demands throughout the day.
These examples illustrate why it is important to consider a child’s experiences across settings and over time, rather than relying only on what others observe in a particular situation.
Why Can Internal Characteristics Be Difficult to Identify?
Some autistic children and adolescents are diagnosed with anxiety, depression, attention-deficit/hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), or other mental health conditions before autism is recognized. These conditions may be identified first because their symptoms are more noticeable or because the child’s autistic characteristics are less apparent.
Importantly, these conditions can coexist with autism. Recognizing autism does not mean that anxiety, depression, ADHD, OCD, or other mental health difficulties should be dismissed or assumed to be part of autism. Each condition may contribute to a child’s experiences and support needs and may require its own assessment and intervention.
When autistic characteristics are less apparent or are camouflaged, they may be more difficult to recognize during an assessment. Although standardized diagnostic tools are important, they may not fully capture an individual’s experiences, particularly when the person compensates for social communication differences or their presentation does not match commonly recognized characteristics of autism.
A comprehensive evaluation considers developmental history, behaviour across settings, social communication, restricted or repetitive patterns of behaviour, interests and activities, and the person’s everyday experiences and support needs. It should also explore whether the individual uses strategies to compensate for or camouflage autistic characteristics that may not be immediately apparent during an assessment.
What Should Parents Look For?
Parents should consider patterns over time rather than focusing on one isolated behaviour. They should observe their child’s social communication, flexibility, sensory experiences, interests, and the effort involved in social situations—not just whether their child appears sociable or performs well at school.
No single trait establishes an autism diagnosis. Assessment considers the broader developmental picture and how these characteristics affect everyday functioning.
Traits Parents May Notice in Children Under Five
Some young children have strong cognitive abilities in particular areas, such as memory, visual reasoning, recognizing patterns, or understanding rules. Others may demonstrate advanced language or academic skills.
These strengths can coexist with challenges in social communication, flexible thinking, sensory processing, or adaptive behaviour (everyday skills needed to function independently). Strong language and academic abilities do not rule out autism, but neither do these strengths alone indicate that a child is autistic.
In some cases, a child’s strengths may make underlying challenges less obvious to parents, educators, and professionals. A child may learn quickly, remember details, or follow familiar rules while finding it difficult to adapt to changes, navigate social interactions, or manage sensory demands. When a child’s strengths in some areas make other differences less apparent, recognition of autistic characteristics and access to appropriate support may be delayed.
Some characteristics parents may notice include:
- Play and peer interaction: Playing alongside other children rather than actively engaging with them, preferring independent play, or imitating peers and copying phrases to participate in social activities.
- Back-and-forth interaction: Having difficulty maintaining reciprocal social interactions.
- Gestures and facial expressions: Using fewer gestures and finding it difficult to interpret other people’s gestures or facial expressions.
- Conversation and shared interests: Talking extensively about favourite topics without responding to the communication partner or sharing attention and interest.
- Understanding perspectives: Finding it challenging to understand what another person knows, feels, wants, or intends.
- Repetitive play: Lining up toys, sorting objects, or arranging items in a particular order repeatedly.
- Less flexible pretend play: Preferring to reproduce the same play scenario repeatedly rather than expand familiar play routines with new ideas.
- Cooperative play: Wanting other children to follow specific rules or a particular script, or wanting friends but struggling to join a group, negotiate play, or adapt to other children’s ideas.
- Routines and transitions: Becoming distressed when routines change or an activity ends unexpectedly or relying on familiar routines, expectations, and sequences to feel secure.
- Communication for different purposes: Using language effectively to request and label objects but showing less spontaneous communication to comment, share experiences, or engage socially. Some children speak well but find reciprocal interaction with peers difficult.
- Scripting: Using memorized phrases or familiar dialogue in particular situations.
- Focused interests: Showing intense interest in particular objects, characters, numbers, letters, or topics.
- Shifting attention: Finding it difficult to move away from a preferred activity or interest.
- Sensory differences: Experiencing sensory challenges that affect eating, sleep, dressing, daily routines, or participation in preschool activities.
- Differences across settings: Appearing to manage well in structured settings but experiencing significant distress or exhaustion afterward.
- Recognizing and communicating emotions: Finding it difficult to identify or communicate emotions, discomfort, hunger, fatigue, or other bodily sensations.
Parents should look at their child’s developmental history, the combination of characteristics present, and how these characteristics affect everyday life.
Traits Parents May Notice in Adolescents
Some autistic adolescents have strong cognitive and language skills while finding social expectations, changing friendships, or increasing emotional and social demands difficult to navigate. They may communicate clearly and perform well academically, so their support needs can be overlooked.
Some characteristics parents may notice include:
- Interpreting non verbal social cues: Difficulty understanding nonverbal cues, sarcasm, joking, indirect communication, or implied meanings.
- Routines and predictability: A strong need for routines or significant distress around unexpected changes.
- Sensory experiences: Sensory sensitivities that interfere with school, social activities, or everyday functioning.
- Personal space: Difficulty recognizing or adapting to other people’s expectations regarding personal space.
- Friendships: Difficulty making or maintaining friendships as peer expectations become more nuanced and social communication becomes more subtle. Social interactions may feel confusing or exhausting.
- Focused interests: Developing deep knowledge about specific subjects or hobbies and enjoying detailed discussions about them, while finding it difficult to shift attention during conversations or classroom activities.
- Repetitive behaviours: Repeatedly tapping fingers, moving feet, clicking pens, or manipulating small objects; repeating phrases, quotations, or dialogue from films, television, or social media; rehearsing conversations or possible social responses; mentally replaying social situations; preferring the same route, seating arrangement, foods, clothing, or belongings; repeatedly watching particular scenes or listening to the same song; or seeking reassurance about plans and expectations.
- Emotional regulation: Experiencing strong emotions, outbursts or shutdowns, while finding it difficult to identify or express what they are feeling.
- Social participation: Withdrawing from group activities or experiencing isolation when social situations become difficult to navigate.
- Strengths and interests: Having strong memory, deep curiosity, or the ability to focus intensely on preferred subjects. These strengths may support success in areas such as technology, the arts, or other specialized academic fields.
- Relationships: Developing dependable friendships and becoming supportive friends and collaborators when relationships are understanding and supportive.
Some adolescents may camouflage their characteristics in an effort to fit in, making their support needs less apparent.
Can Adults Also Recognize These Characteristics Later in Life?
Some adults with strong language skills and cognitive abilities may recognize longstanding differences in social interaction, sensory processing, emotional regulation, daily routines, or flexible thinking. They may begin to suspect they are autistic after learning more about autism or recognizing similarities between their own experiences and those of autistic people.
Examples of characteristics may include:
- Finding small talk confusing, tiring, or difficult to follow, particularly when social cues are unspoken.
- Interpreting language literally or finding hints and implied intentions difficult to understand.
- Experiencing sensory information like everyday sounds, textures, visual input, or temperature changes as overwhelming.
- Repeating actions, phrases, questions, or stories as a communicative or regulatory function.
- Relying on familiar preferences and routines for comfort and predictability.
- Experiencing emotions intensely or finding emotional regulation challenging.
- Finding changes to familiar routines distressing.
- Masking autistic characteristics in public to fit in with others.
- Developing strong interests and sharing extensive information about preferred topics as a way of connecting with others.
- Having particular strengths or talents, such as exceptional memory, musical ability, mathematical skills, or attention to detail.
Adults who recognize a longstanding pattern of differences may consider a diagnostic evaluation to better understand their experiences and support needs.
