Autism in Girls: Why It's Often Missed and What Parents Should Know

Autism in girls is significantly underdiagnosed in the UK. Girls are four times less likely to receive an autism diagnosis than boys, not because fewer girls are autistic, but because autism often presents differently in girls and diagnostic criteria have traditionally been based on how autism appears in boys.

Understanding these differences is crucial for parents who suspect their daughter may be autistic. Early diagnosis can transform a girl's educational experience, self-understanding, and wellbeing.

How Autism Presents Differently in Girls

Girls with autism are often better at "masking" or "camouflaging" their autistic traits, suppressing natural behaviours to fit in socially. This can mean they appear more socially capable than boys with autism, making their difficulties less obvious to teachers and professionals.

Girls may also have intense, focused interests that appear more socially acceptable—for example, collecting information about horses or reading extensively about animals—rather than the stereotypical interests associated with autism. They may have close friendships but struggle with the unwritten rules of group social interaction.

Common Traits in Autistic Girls

• Strong preference for one or two close friends rather than large social groups
• Intense, passionate interests that dominate conversations and free time
• Difficulty understanding social nuances and unwritten social rules
• Anxiety, particularly around social situations or changes to routine
• Perfectionism and high academic standards
• Sensory sensitivities (to sounds, textures, or lights)
• Executive function difficulties (organisation, time management, planning)

Getting an Assessment

If you're concerned your daughter may be autistic, start by speaking with your GP or school SENCo. Diagnosis typically involves assessment by a specialist, such as a clinical psychologist or psychiatrist experienced in autism in girls. This may be available through the NHS, though waiting times vary by region.

Keep detailed notes of your daughter's behaviours, interests, and social interactions. This information is valuable during assessment. Connect with other parents and autistic women—their experiences can be invaluable in understanding your daughter's needs.

A diagnosis of autism isn't a label limiting your daughter's potential; it's a framework for understanding her strengths and challenges, enabling better support and self-acceptance.
