What is ADHD? Recognising Attention Deficit Symptoms in Children

Your child can't sit still in class, leaves homework half-finished, or forgets instructions the moment you give them. Is this just high energy — or a sign they need support? Recognising ADHD is the first step toward getting it right.

What is ADHD?

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects a child's attention span, impulse control and activity level. It stems from differences in how the brain's executive functions develop — it is not the result of laziness, poor parenting or inadequate discipline.

Symptoms typically begin before the age of 12 and are observed in at least two settings — for example, both at home and at school. Many children receive a diagnosis during primary school years, although some are not identified until adolescence.

DSM-5 diagnostic criterion: the six-month rule

An ADHD diagnosis requires that at least six symptoms of inattention or hyperactivity-impulsivity have persisted for at least six months, are inconsistent with the child's developmental level, and are impairing functioning across more than one setting.

What do ADHD symptoms look like in children?

ADHD symptoms fall into three main groups. Not every child will show all three — which is part of what makes identification challenging:

Inattention

• Difficulty noticing details
• Unable to sustain attention on tasks or play
• Seems not to listen when spoken to directly
• Fails to follow through on instructions
• Frequently loses belongings
• Easily distracted by external stimuli
• Forgetful in daily activities

Hyperactivity

• Fidgets with hands or feet
• Leaves seat when expected to remain seated
• Runs or climbs in inappropriate situations
• Difficulty playing quietly
• Often "on the go" or driven by a motor
• Talks excessively

Impulsivity

• Blurts out answers before a question is finished
• Can't wait their turn
• Interrupts or intrudes on others
• Acts without thinking about consequences
• Extreme emotional reactions

What parents and teachers typically notice

ADHD presents differently depending on the setting. Here is what is most commonly reported:

At home

Getting up repeatedly while doing homework, being able to sit at a screen for hours but unable to hold a book for five minutes, constantly losing things, difficulty remembering household rules, sudden conflicts with siblings.

At school

Struggling to follow lessons, copying errors, inability to remain seated, difficulty waiting their turn, friction in group work, poor use of exam time.

In social situations

Disregarding or quickly breaking the rules of a game, fragile friendships, sudden outbursts of anger, very low tolerance for frustration.

A common misconception: "But they can play video games for hours"

Children with ADHD can focus intensely on activities they find highly engaging — this is called hyperfocus. It does not rule out ADHD; rather, it reflects how their brain's reward system works. The core difficulty is not an absence of attention but an inability to direct attention voluntarily.

Types of ADHD

Predominantly Inattentive Type

Hyperactivity is not prominent; the child may appear calm or even dreamy. More commonly seen in girls, which means diagnosis is often delayed.

Predominantly Hyperactive-Impulsive Type

Motor restlessness and impulse control are more prominent than attention difficulties. More frequently seen in boys and more likely to be identified early.

Combined Type

Both symptom groups are present and significant. This is the most common presentation of ADHD.

How to tell ADHD apart from typical child development

Not every energetic child has ADHD. These questions can help you distinguish:

Are the symptoms visible in more than one setting — both at home and at school?
Are the behaviours negatively affecting the child's academic performance, friendships or self-esteem?
Has this been going on consistently for at least six months?
Are these behaviours noticeably more intense than in peers of the same age?

If you answer "yes" to most of these, it is worth speaking with a specialist.

How does the assessment process work?

An ADHD diagnosis is not based on a single test. A thorough evaluation typically involves:

1

Clinical interviews

Separate interviews with the child and parents covering developmental history, school performance and family dynamics.
2

Parent and teacher rating scales

Standardised tools such as the Conners or Vanderbilt scales measure symptom severity across different settings.
3

Psychological testing

Tests measuring attention, memory and executive functions help distinguish ADHD from learning difficulties, anxiety or other conditions.
4

Medical evaluation

Medical causes of similar symptoms — such as hearing difficulties, thyroid problems or sleep disorders — are ruled out.

Treatment and support options

ADHD is a treatable condition. The most effective approach combines more than one strategy:

Behavioural Therapy

The first-line choice, particularly for children under 6. It teaches the child self-regulation skills and helps parents build consistent structure at home.
Parent Training

Expert guidance on communication strategies, reward systems and home routines. Research shows that parent training is as effective as direct child therapy for many families.
Cognitive Behavioural Therapy (CBT)

Particularly helpful for school-age children and adolescents. Addresses organisation, time management and unhelpful thinking patterns.
School Accommodations

Extended time in exams, a front-row seat, homework tracking tools — reasonable adjustments that can significantly improve academic outcomes.
Medication

Prescribed by a psychiatrist after full evaluation. For moderate to severe presentations, stimulant or non-stimulant medication combined with behavioural support can produce meaningful results.

Why early support matters

Children who grow up without a diagnosis are sometimes labelled "lazy", "disrespectful" or "a failure". These labels erode self-confidence and increase the risk of secondary anxiety or depression. Early intervention can break that cycle and bring the child's strengths to the fore.
