Autism in Girls vs Boys: What UK Parents Need to Know in 2025

If your daughter seems a little “quirky” or struggles in ways you can’t quite put your finger on—but keeps slipping through the diagnostic net—you’re not alone. For decades, autism has been mostly understood through how it shows up in boys. The result? Too many girls are left undiagnosed, misunderstood, and unsupported.

It’s time we talk honestly about the differences—and what UK parents need to watch out for in 2025 and beyond.

The Hidden Struggle of Autistic Girls

Take Sarah, for example. Her son was diagnosed with autism at age 4 after his nursery raised some concerns about his behaviour. He was having loud meltdowns and didn’t seem to connect with the other kids.

Her daughter? She didn’t get diagnosed until she was 14—after years of being labelled “shy,” “anxious,” or “overly sensitive.”

Sadly, Sarah’s story isn’t unusual.

In the UK today:

• Boys are four times more likely to be diagnosed with autism than girls

• Girls often wait 4–7 years longer than boys for a diagnosis

• Many autistic women only discover the truth about themselves in adulthood, often after years of being misdiagnosed

7 Key Differences Parents Should Know

1. Social Camouflage

• Girls tend to mimic others—copying how friends speak, gesture, and act, so they blend in.

• Boys often stand out more in social settings and struggle to “read the room.”

2. Special Interests

• Girls’ passions might look typical—like horses, celebrities, or fashion—but the intensity is off the scale.

• Boys often gravitate towards structured or unusual interests—like trains, maps, or number patterns.

3. Meltdowns vs Shutdowns

• Girls tend to internalise their stress. You might not see a public meltdown—but later, she may withdraw, cry, or even self-harm.

• Boys are more likely to express their overwhelm outwardly through shouting or aggression.

4. Coping at School

• Girls work hard to fit in and follow the rules—but often come home utterly drained.

• Boys are more likely to show behavioural difficulties during the school day.

5. The Diagnosis Trap

• Girls often get misdiagnosed with anxiety, depression, or even borderline personality disorder first.

• Boys usually show more of the “classic” autism signs clinicians are trained to spot.

6. Sensory Sensitivities

• Girls might endure scratchy fabrics, loud noises, or bright lights just to seem “normal.”

• Boys may flat-out refuse to wear certain clothes or go to noisy places.

7. Adulthood Outcomes

• Autistic women often hit a wall in their 30s after years of masking—they burn out.

• Autistic men are more likely to find their niche, especially in structured fields like tech or engineering.

The Masking Crisis

Imagine spending every day acting in a play where you don’t know the lines. That’s what masking feels like. Many autistic girls become expert performers—forcing eye contact, memorising what to say in social situations, and hiding their natural behaviours.

A 16-year-old girl shared:

“By Friday, I’m so drained I can’t even speak. Weekends are just recovery time.”

Why the NHS Still Misses Girls

Here’s the hard truth: many of the assessment tools used by the NHS were designed based on how autism appears in boys. That means:

• Girls often don’t tick the “right” boxes

• They need to display more extreme signs to get a diagnosis

• They’re often told things like “You’re too chatty to be autistic”, even when they’re clearly struggling

Take 12-year-old Emily. She seems outgoing, loves fashion, and has friends. But behind the scenes:

• She studies YouTube videos to figure out how to socialise

• She gets headaches from forcing eye contact all day

• She’s memorised over 200 “normal” conversation starters

What Parents Can Do Right Now

💡 Look Beyond the Stereotypes

Ask yourself:

• Does your daughter seem utterly exhausted after school?

• Are her friendships scripted or one-sided?

• Does she have intense interests—even if they’re seen as “normal”?

✍️ Start Keeping Notes

Begin a simple diary. Look for patterns in:

• Social burnout or anxiety

• Sensory triggers (like clothing tags or noise)

• Rigid routines or perfectionism

🩺 Push for the Right Assessment

• Ask for a referral to a specialist who understands how autism presents in girls

• Share trusted NHS resources (search “Autism in Women and Girls” on NHS.uk)

• If waiting times are too long, consider a private evaluation

Life After Diagnosis

For 14-year-old Maya, finally getting a diagnosis was life-changing. Her school now lets her wear noise-cancelling headphones. She no longer forces herself to make eye contact. And most importantly—she understands herself now.

Support Available in the UK

• EHCP plans (Education, Health & Care Plans) can be tailored to autistic girls

• CAMHS (Child and Adolescent Mental Health Services) may offer therapy better suited for girls

• Local and virtual support groups for autistic girls and their families are growing fast

The Future Is Changing

The good news? In 2025, we’re seeing real progress in the UK:

✅ New diagnostic tools are being trialled with girls in mind
✅ More teachers are being trained to spot the subtle signs
✅ And slowly but surely, the narrative is shifting: autism isn’t just a “male condition”

As one newly diagnosed woman shared:

“Understanding that I wasn’t broken—just different—changed everything.”
