Spotting hidden autism symptoms in girls

Girls can often mask signs of autism to fit in, feel safe and gain acceptance. But it takes a heavy toll for those on the spectrum, says Sarah-Jane Critchley…

When you look at Beth, autism is not the first thing that you would think of. She is bright, open, smiley, makes great eye contact and comes alive when you start talking about Harry Potter. Before long, you start to realise that she could hijack your entire with her in-depth characterisation of Hermione.

She knows the likes and dislikes of all of the characters in the book, what house they belong to at Hogwarts, their family histories and their motivations. Yet in the playground, she is completely at sea. Unless she can persuade other children to join in her specific game, she will struggle to play at all.

Like many autistic girls, she seems on the edge of things, rather than in the centre. She is struggling and yet you wouldn’t know it. She is working so very hard to fit in, yet at a huge cost. It’s overwhelming and the effort is exhausting.

“She is struggling and yet you wouldn’t know it”

The story of each autistic girl is as different as the girls themselves. They can be tomboys, girly or geeky – and yet they share huge vulnerabilities.

Masking in autistic girls

Maryam is almost silent in class. She sits at the back watching how the other girls act and will never put her hand up. Now in Y6, she wears her clothes exactly the way the popular girls do. But unlike them, she doesn’t speak or laugh at school and the other children pick her last for team games.

She has a wide group of people she calls friends. However, none of them choose to sit next to her on the school trip. Like so many other girls, Maryam is masking or camouflaging to hide the fact she is autistic.

It’s a mask she can’t take off because she has to hide to fit in, to feel safe and have the same opportunities as everyone else. She buries her own identity so that even others accept her, she feels that no one knows the ‘real’ her. This takes huge, consistent effort and comes at a very high psychological cost.

She falls to pieces when she gets home. She appears fine at school, but her parents are worried.

It can feel almost impossible to meet the needs of each and every girl. This is especially the case when so much of their pain is internal. But if you look deeper, it isn’t hard to spot the child who is deeply unhappy and uncomfortable.

“She falls to pieces when she gets home”

Sixth sense

Experienced and empathetic teachers will have almost a sixth sense for the children that are struggling in their class. Tapping into your empathy can make the difference between a child being able to stay in class, develop their interests and learn the vital skills they need to navigate the confusing social world, and being so stressed they can no longer attend school at all.

It can help you to know that when you create the right classroom environment and get it right for these incredible vulnerable girls, you will be helping all of your pupils – and boys mask, too.

Everyone benefits from having clear structure to the day and their work, and knowing exactly what you expect.


Ava is amazingly artistic and is a fantastic actress and dancer. Her body communicates emotion in a way that she can’t. In class though, Ava is a challenging child. She will blurt out anything that is crossing her mind at the time. She has been in trouble for hitting another child.

What you might not have seen was the child who kept poking her while you were working on the board until she reacted. Autistic girls who are desperate to fit in can be very trusting. They completely miss social cues and may be manipulated into doing a number of things against their best interests.

This could be anything from giving away their lunch, their money or possessions to a friend, to being manipulated into negative or risky behaviour.

“Autistic girls who are desperate to fit in can be very trusting”


Although autistic girls come in all shapes and sizes, what unites all of them is a need for support that understands the condition and the specific vulnerabilities that go with being an autistic girl in society.

Unsupported and unidentified autistic girls and women are far more likely to experience mental illness, exploitation and abuse in later life.

This means it’s vital that we provide support to give them the best opportunity to develop into the amazing potential which they hold, for their benefit and for ours.

How autism affects girls’ social relationships

The landscape of female friendships can be tough to negotiate for anyone. However, autistic girls often have the wrong map altogether, explains Felicity Sedgewick…

Autistic girls can have social behaviours and friendships that look very different from both those of autistic boys and non-autistic girls.

For example, girls may mimic the behaviours, interests and even speech patterns of people they are friends with. This is an attempt to fit in and be accepted. They may also memorise information about their friends’ interests, or learn ‘scripts’ so that they can talk to new people.

Autistic girls may become fixated on one person in particular. They focus on making that person their best – and only – friend. This can be very intense for both people and can sometimes lead to a falling-out.

“Autistic girls may become fixated on one person in particular”

Autistic girls find recognising and managing conflict much more difficult than non-autistic girls do, impacting on their ability to repair and maintain friendships. Alternatively, some girls will form many casual friendships, but not stick to one group. They might not have close friends with whom they spend most of their time.

Guiding hands

It can be difficult for staff to support the social lives of autistic students alongside their studies, but it is a crucial aspect of school life and personal development.

Autistic girls may take literally whatever is said to them, leaving them vulnerable to being manipulated. Their less-developed social awareness can leave them open to gossip and exclusion. It is important to try and notice these behaviours and intervene or explain.

“Their less developed social awareness can leave them open to gossip and exclusion”

Girls who have just one or two very intense friendships may need help widening their circle and understanding why this matters.

Explaining that most people have several friends so that no single person gets overloaded or bored, and helping them find other young people with shared interests, can be a good form of support.

Girls who appear to be friendly with almost everyone, but who have no close friends, may need support in spending more time with peers. However, they may be happy with their less demanding, casual friendships.

The best course of action is to let each girl choose what sorts of friendships she prefers and to try to help her make and keep the friends she wants to have.

Undiagnosed autism in girls

Just because she’s not causing trouble, it doesn’t mean a student isn’t struggling with undiagnosed autism, explains Gordon Cairns…

Imagine trying to identify a ‘problem’ pupil in class who is eager to please by being extremely helpful, has a desire to succeed and may even have perfectionist tendencies.

Alternatively, the ‘difficulty’ could be that she has a passive personality, is compliant and may be one of the quieter pupils in the room. Perhaps she comes across as shy, innocent and unassuming and is very unlikely to be disruptive.

Yet a girl displaying some or all of these behaviours may well have an undiagnosed autism spectrum disorder. Worryingly, if the condition isn’t spotted, she could be experiencing eating disorders or self-harming and developing mental health issues that last into her adult life.

Under the radar

The trouble is that to a harassed teacher, with 30 demanding pupils and a range of behavioural issues, the girl with these traits may sound like the ideal student.

Furthermore, she may be very good at camouflaging her difficulties by mimicking more sociably able pupils in the class, making her condition even more difficult to recognise.

Contrast this with a lot of autistic boys who display a number of recognisable traits, such as a lack of empathy or an obsessional interest with obscure subjects, such as light bulbs.

It has been notoriously difficult to find a ratio of male-to-female autism that everyone agrees on. Figures range from, at one extreme, a 2:1 male-to-female ratio, to others believing that only one girl to every 16 boys has the condition.

From my own experience of working in an autism unit for over a decade, our numbers typically break down to one girl for every ten boys.

A National Autistic Society survey from 2012 showed how problematic it is to get a diagnosis for a girl. While 50% of boys with autism were diagnosed by the age of 11, only 20% of girls were. Just as worryingly, 42% of girls were reported as having been misdiagnosed, compared with 30% of boys.

“While 50% of boys with autism were diagnosed by the age of 11, only 20% of girls were”

Undiagnosed dangers

While these girls may outwardly be model pupils, their stress will often have to be released through another outlet such as self-harming or an eating disorder.

In fact, an increasing number of young women are being diagnosed with autism after being initially seen by a doctor for an unrelated condition. An article published in Neuropsychiatric Disease and Treatment in 2015 identified a connection between young women who have been diagnosed with anorexia nervosa and Asperger syndrome.

The risk is that the autistic element of these girls’ mental make-up is overlooked as clinicians look to treat the eating disorder. This may then lead to a simplification in the diagnostic consideration and therapeutic procedures.

The good news is that once they have received a diagnosis, girls can receive additional support. With greater understanding of self, their anxiety will lessen and they will be less likely to take part in harmful activities which could cause lasting physical damage.

By contrast, if left undiagnosed, in later life they might have a history of mental health issues and in extreme cases, feel suicidal.
