If you are looking for signs of ADHD in your child, you may expect hyperactivity or disruptive behaviour to be the most obvious clues. However, ADHD can appear differently from one child to another, and some less visible signs may be recognised less often in girls.
Your child may experience difficulties with attention, impulsivity or activity levels without always showing behaviour that seems obviously disruptive. Understanding these differences can help you recognise potential signs of ADHD and consider whether your child may benefit from further assessment.
Does ADHD Affect Both Boys and Girls?
ADHD can affect both boys and girls, with common difficulties involving attention, hyperactivity and impulsivity. However, these difficulties can appear in different ways from one child to another, so there is no single pattern that applies to every child.
When you are considering whether your child may have ADHD, it is more helpful to focus on their individual symptoms and how these affect everyday life. Their behaviour, development and experiences across different settings are more important than whether they are a boy or a girl.
Why Can ADHD Look Different in Boys and Girls?
ADHD can present differently from one child to another, with boys sometimes showing more noticeable hyperactive or disruptive behaviour and girls more often showing less obvious inattention or internal restlessness. These are general patterns rather than fixed rules, so your child’s individual symptoms and their impact on everyday life are more important than gender.
How ADHD May Present in Boys and Girls
| Area | Boys May Sometimes Show | Girls May Sometimes Show | Important Consideration |
| Hyperactivity | More visible physical activity or restlessness | Less obvious restlessness or internal feelings of being unsettled | Either can experience hyperactivity |
| Inattention | Difficulty focusing or completing tasks | Daydreaming, forgetfulness or appearing not to listen | Inattention can occur in both boys and girls |
| Impulsivity | Interrupting, acting quickly or difficulty waiting | Impulsive behaviour may be less noticeable | Individual symptoms vary considerably |
| Behaviour at school | More noticeable disruptive or active behaviour in some children | Difficulties may be quieter and less disruptive | Less disruptive symptoms can still affect learning |
| Emotional difficulties | Frustration or difficulty managing emotions may be noticeable | Emotional distress may be less visible to others | Emotional regulation difficulties can occur in any child |
| Recognition of ADHD | Symptoms may attract attention sooner | Less obvious symptoms may sometimes be overlooked | Assessment should focus on the child’s overall pattern |
| Individual differences | Boys do not all show the same symptoms | Girls do not all show the same symptoms | Your child’s needs should be considered individually |
What Can ADHD Look Like in Boys?
You may notice behaviours such as excessive running around, difficulty staying seated, interrupting others or acting without thinking. These signs can be more noticeable during everyday activities and may affect how your child manages situations at home or at school.
Because these behaviours can attract attention, concerns about ADHD may sometimes be raised more quickly. However, it is still important to consider the full pattern of your child’s symptoms and how they affect their everyday life.
What Can ADHD Look Like in Girls?
In girls, ADHD may be more noticeable through distractibility, difficulty concentrating, forgetfulness or problems with organisation rather than obvious disruptive behaviour. Your daughter may seem quiet or appear to manage well, even when she is finding certain tasks and everyday demands difficult.
If she does not draw attention to her difficulties, signs of ADHD can be easier to overlook at home or school. Looking beyond disruptive behaviour and considering less visible challenges can help you recognise when your child may need further assessment.
Can Girls Still Be Hyperactive?
Yes, girls with ADHD can be hyperactive, although their activity may sometimes look different from the behaviour traditionally associated with ADHD. You might notice frequent talking, fidgeting, restlessness or difficulty remaining settled rather than constant running around or disruptive movement.
These behaviours can still affect your child’s ability to concentrate, participate in activities or manage everyday situations. Looking at the overall pattern of their behaviour can help you and their specialist understand whether hyperactivity may be part of their difficulties.
Is Inattentive ADHD Easier to Miss?
Inattentive symptoms can be less noticeable because they may not disrupt the classroom or family routine in an obvious way. Your child might quietly lose concentration, forget instructions or struggle to organise their work while still appearing well behaved to the people around them.
Because these difficulties may not attract immediate attention, they can sometimes be overlooked. Paying attention to patterns such as forgetfulness, distractibility and difficulty completing tasks can help you recognise when your child may need further assessment.
Why Is ADHD Often Missed in Girls?
NICE advises that ADHD is thought to be under-recognised in girls and women, who may also be less likely to be referred for an assessment. One reason is that inattentive or less outwardly disruptive difficulties may not attract the same immediate attention as more visible signs of hyperactivity.
Your child may therefore be experiencing difficulties that are not immediately obvious to the people around her. Looking carefully at patterns of attention, organisation and everyday functioning can help ensure that less visible signs are not overlooked.
Can Girls Hide Their ADHD Difficulties?
Some girls may put considerable effort into fitting in, staying organised or preventing others from noticing that they are struggling. Your child may appear to be managing well on the outside while using significant effort to cope with attention, organisation or everyday demands.
You may only notice these difficulties through signs such as exhaustion, feeling overwhelmed, falling behind with schoolwork or struggling to manage everyday responsibilities. Looking at what happens beneath the surface can help you recognise difficulties that may otherwise be easy to overlook.
How Can ADHD Affect Boys at School?
A boy with prominent hyperactivity or impulsivity may find it difficult to sit through lessons, wait for his turn or avoid interrupting others. These challenges can make it harder for your child to follow classroom routines and manage the demands of school.
Teachers may therefore notice behavioural difficulties even when your child is capable of understanding the academic work. Looking at both behaviour and learning can help you and the school understand where your child may need additional support.
How Can ADHD Affect Girls at School?
A girl with ADHD may struggle to concentrate, organise schoolwork, remember instructions or complete tasks without necessarily disrupting the classroom. These difficulties can affect her learning and day-to-day schoolwork even when her behaviour appears quiet or well managed.
If these signs are mistaken for daydreaming, carelessness or a lack of effort, the underlying ADHD symptoms may remain unrecognised for longer. Paying attention to ongoing difficulties with concentration, organisation and task completion can help identify when your child may need further support.
Can ADHD Affect Confidence and Emotions?
ADHD-related difficulties with schoolwork, organisation or friendships can sometimes affect your child’s confidence and emotions. Your child may become frustrated or feel they are not meeting expectations when everyday tasks seem harder.
- Self-confidence: Repeated difficulties may affect how your child feels about themselves.
- Frustration: Challenges with tasks or organisation can lead to feelings of frustration.
- Self-blame: Some children may blame themselves for difficulties they do not understand.
- Low self-esteem: Ongoing challenges may affect your child’s sense of ability and confidence.
- Low mood: Emotional difficulties can sometimes develop alongside ADHD symptoms.
Recognising these emotional effects can help your child’s specialist understand the wider impact of their difficulties. It also allows you to identify areas where your child may need additional support.
Should Parents Look Beyond Hyperactivity?
Yes, focusing only on obvious hyperactivity could mean you miss other important signs of ADHD in your child. Difficulties with concentration, forgetfulness, organisation, listening and completing tasks can also be significant when they are persistent and affect everyday life.
Your child may not always appear restless or disruptive, yet they may still find everyday tasks challenging. Looking at the wider pattern of their behaviour can help you recognise difficulties that may otherwise be overlooked.
What Should Teachers Look For?
Teachers should look for persistent patterns involving attention, impulsivity and activity rather than focusing only on disruptive classroom behaviour. A child may experience difficulties even when they appear quiet, settled or well behaved during lessons.
If your child regularly loses track of instructions, struggles to organise their work or appears easily distracted, these signs may still be important. Recognising these patterns can help ensure that your child receives appropriate support or is considered for further assessment.
Are Different Diagnostic Criteria Used for Boys and Girls?
Boys and girls are assessed using the same recognised ADHD diagnostic framework rather than separate criteria based on sex. Your specialist considers your child’s symptoms, development and the extent to which their difficulties affect everyday life.
They will also look at whether these difficulties occur across important settings, such as home and school. This means your child’s individual symptoms and level of impairment are considered rather than applying different diagnostic standards based on whether they are a boy or a girl.
When Should You Consider an ADHD Assessment?
You may want to seek professional advice when difficulties with concentration, impulsivity, restlessness or organisation are persistent and affecting your child’s learning, relationships or everyday life. It is worth paying attention to patterns that continue over time rather than focusing on occasional difficulties.
This applies whether your child’s symptoms are highly visible or much quieter and easier for others to miss. Looking at how these difficulties affect your child across different areas of everyday life can help you decide when further assessment may be appropriate.
How Can the Right ADHD Support Help?
Support should be based on your child’s individual needs rather than assumptions about how ADHD should look in boys or girls. Understanding how your child’s symptoms affect their everyday life can help you and their specialist identify suitable ways to support them.

UK Guidance Note
NICE advises healthcare professionals to be particularly aware that ADHD is thought to be under-recognised in girls and women. Your daughter should not be excluded from assessment simply because she is quiet, academically capable or does not display obvious disruptive behaviour.
Your child should receive the same comprehensive diagnostic assessment regardless of sex. Their symptoms should occur frequently in at least two important settings and cause at least moderate psychological, social or educational impairment, while being considered alongside their developmental history, mental health, physical health and possible coexisting conditions.
Frequently Asked Questions
1. Is ADHD more common in boys than girls?
ADHD is diagnosed more often in boys, but this does not necessarily mean that girls are unaffected. Girls may be less likely to be identified when their symptoms are mainly related to inattention or are less outwardly disruptive.
2. Can ADHD symptoms be different in boys and girls?
The core symptoms of ADHD are the same, involving inattention, hyperactivity and impulsivity. However, children can express these difficulties differently, with some girls showing less obvious hyperactivity and more noticeable problems with concentration or organisation.
3. Why is ADHD sometimes missed in girls?
ADHD may be missed when a girl does not display obvious disruptive or hyperactive behaviour. Quiet inattention, forgetfulness, difficulty organising schoolwork or daydreaming may be overlooked or attributed to other causes.
4. Can girls with ADHD be hyperactive?
Yes. Girls can experience significant hyperactivity or impulsivity, although it may appear as frequent talking, fidgeting, restlessness or difficulty remaining settled rather than obvious physical disruption.
5. What are common signs of inattentive ADHD in girls?
You may notice that your child frequently forgets instructions, loses belongings, struggles to complete tasks, becomes easily distracted or has difficulty organising schoolwork. These signs can be subtle, particularly when your child is otherwise quiet and well behaved.
6. Can boys have mainly inattentive ADHD?
Yes. ADHD does not follow a fixed pattern based on sex, and boys can also have predominantly inattentive symptoms. A child does not need to be noticeably hyperactive or disruptive for ADHD to be considered.
7. How can ADHD affect school differently in boys and girls?
A child with prominent hyperactivity or impulsivity may attract attention because of interruptions or difficulty remaining seated. A child with mainly inattentive symptoms may instead quietly fall behind, miss instructions or struggle with organisation without disrupting the classroom.
8. Can girls hide or compensate for ADHD symptoms?
Some girls may develop strategies that make their difficulties less obvious to other people. They may work particularly hard to stay organised or appear attentive, while experiencing significant difficulty that becomes more noticeable when demands increase.
9. Are boys and girls diagnosed using different ADHD criteria?
No. Boys and girls are assessed using the same recognised diagnostic criteria. The specialist considers the child’s symptoms, development, impairment and experiences across relevant settings rather than applying different diagnostic standards based on sex.
10. When should I consider an ADHD assessment for my child?
Consider seeking professional advice when difficulties with attention, impulsivity, hyperactivity or organisation are persistent and affect your child’s learning, relationships or everyday life. This is important whether your child’s difficulties are obvious and disruptive or quieter and easier to overlook.
Final Thoughts: Recognising ADHD Beyond Stereotypes
ADHD can present differently from one child to another, so looking beyond obvious hyperactivity can help you recognise difficulties that might otherwise be overlooked.
