Autism in women and girls is often under-recognised, not because it is less common, but because it can present in ways that are frequently misunderstood or attributed to other conditions. Many autistic women and girls receive multiple mental health diagnoses before autism is ever considered, sometimes only discovering their neurodivergence in adulthood.

Understanding these overlapping experiences is key to improving recognition and access to appropriate support.

Misdiagnosis and overlapping conditions

Autistic traits in women and girls are often interpreted through the lens of mental health or personality-based explanations. As a result, individuals may be diagnosed with conditions such as:

• Anxiety disorders
• Depression
• Eating disorders
• Borderline personality disorder (BPD)
• Obsessive-compulsive disorder (OCD)

While these conditions can co-occur with autism, they may sometimes mask underlying autistic traits or delay a correct understanding of an individual’s neurodevelopmental profile.

This is often referred to as misdiagnosis or diagnostic overshadowing in autism, where emotional or behavioural difficulties are seen without recognising the underlying autism.

Emotional regulation and internal experiences

Many autistic women and girls experience intense internal emotional worlds that are not always visible to others. This can include:

• High levels of anxiety, especially in social situations
• Emotional overwhelm or shutdowns rather than outward meltdowns
• Difficulty identifying or expressing emotions (sometimes referred to as alexithymia)
• People-pleasing behaviours that hide distress

Because these experiences are internalised, they may be misinterpreted as mood disorders rather than signs of autism spectrum disorder in females.

Social expectations and pressure to adapt

Social expectations placed on girls from a young age can contribute to late recognition of autism. Many autistic women and girls learn to adapt their behaviour early in life to meet expectations around communication, friendships, and emotional expression.

This can include:

• Copying peers to “fit in” socially
• Suppressing stimming or natural behaviours
• Developing highly rehearsed social scripts
• Becoming highly aware of social judgement

While these adaptations may help in the short term, they can lead to long-term exhaustion, anxiety, and loss of authenticity, often contributing to autistic burnout in women later in life.

The impact of late diagnosis

For many women, an autism diagnosis comes after years of feeling “different” without understanding why. A late autism diagnosis in women can bring both relief and reflection, helping to reframe past experiences through a new lens.

However, it can also involve processing years of misinterpretation, incorrect treatment, or feeling misunderstood within healthcare or educational systems.

Why recognition matters

Improved awareness of autism in women and girls helps reduce misdiagnosis and supports earlier identification. This can lead to more appropriate support, better mental health outcomes, and a clearer understanding of individual needs.

Recognising autism alongside co-occurring mental health conditions allows for a more holistic and accurate approach to care.

Final thoughts

Autism in women and girls is complex, often shaped by internalised experiences, social expectations, and overlapping mental health presentations. Increasing awareness is helping more individuals receive clearer answers and more appropriate support, sometimes after many years of uncertainty.

If you recognise yourself in these experiences, seeking an autism assessment or post-diagnostic support may help provide clarity and direction.
