Autistic girls often fall through the cracks.

Many are diagnosed later than boys, or missed entirely.

Because their traits can be subtle or masked, they may grow up feeling different to others without knowing why.

Many people still picture autism as a young boy who loves trains or flaps his hands. But it can look different in girls and women.

Many autistic girls learn to "camouflage" their differences to fit in with peers, often without realising they’re doing it. They copy social behaviour, rehearse conversations, or hide sensory discomfort. Masking can help them feel accepted, but it often leads to anxiety, burnout, or feeling unsure of who they really are. 

What are some signs of autism in women and girls?

Here are some ways that autism can present differently in girls and women:

Special interests - Autistic girls often have deep, focused interests but they’re easily overlooked because they're seen as “socially acceptable”. They might know everything about animals, celebrities, books, or a TV series, and spend hours immersed in that world.

Repetitive behaviours - Repetition can be subtle. Instead of lining up toys or repeating phrases, an autistic girl might listen to the same song on repeat, rewatch a favourite film, or reread a comforting book. These routines help create predictability and calm.

Anxiety - Many autistic girls and women experience high anxiety from trying to appear “fine”. They may hold everything together at school or work, then have meltdowns or shutdowns at home where they feel safe.

Friendships and socialising - Autistic girls may appear sociable but struggle with group dynamics, unspoken rules, or maintaining friendships, even when they seem included.

Why are women often diagnosed with autism later in life?

Because girls often mask so effectively, many don’t receive a diagnosis until adulthood. They may have been mislabelled as anxious, shy, or even diagnosed with a personality disorder. Some only recognise autism in themselves when their child or grandchild is assessed.

Autism is a spectrum, and every autistic girl or woman is different. Some show traits typically associated with boys; others present in quieter, less visible ways. What matters most is understanding their experience so they can access support and live more authentically.
