ADHD in children in Singapore: early signs, assessment and support

If your child is under 5, busy and easily distracted, that's common. The NHS says it doesn't mean ADHD on its own. ADHD in children means attention and self-control problems that are strong, last for months and show up in more than one place. In Singapore, your polyclinic doctor or a CHAS GP can refer a child aged 6 or under to the Child Development Programme at KKH or NUH.

What to do if you think your child might have ADHD, step by step

1. Write down what you see, where it happens and how long it's been going on. AAP says the doctor will ask how long the signs have lasted and how they affect your family.
2. Ask your child's preschool teacher what they notice in class. HPB's Parent Hub says ADHD behaviour shows up in more than one setting, such as home, school and the supermarket.
3. Note how your child is sleeping and whether anything at home has been stressful. The NHS says high energy in under-5s can be a sign of being tired, anxious or stressed.
4. Book a visit with your polyclinic doctor or a CHAS GP. MOH told Parliament in February 2024 that children aged 6 and below referred from either can get consultations and therapy at KKH or NUH, subsidised by up to 70 percent.
5. Bring your notes, your child's Child Health Booklet and any preschool report. Our child health screening guide explains the booklet's checks.
6. Expect a long talk and some forms. AAP says there's no single test for ADHD, and you may fill in checklists or rating scales.
7. Ask whether parent training is part of the plan. CDC says that for children under 6, the AAP recommends behaviour therapy first, before medicine.
8. Share the plan with the preschool and with everyone who minds your child at home. NUH asks parents and school to work hand in hand on it.
9. Get support for yourself too. NHG says parents of children with ADHD often feel stressed and should lean on family and the school.

How doctors describe ADHD

NUH describes ADHD as a neurodevelopmental condition that affects attention, concentration, activity level and impulse control. NHG says it begins early, usually before age 7. It isn't caused by poor parenting, and a family history makes it more likely. MOH told Parliament in 2024 that research puts it at 5 to 8 percent of children and adolescents.

SingHealth's HealthXchange says ADHD is four times more common in boys. The NHS says girls get recognised less often, because they more often have inattentive signs, which are harder to spot. A quiet child who drifts off can have ADHD too.

Is my child just active, or is it ADHD?

HPB's Parent Hub says it's quite normal for children to be active, inattentive and impulsive. What doctors look at is how strong the behaviour is, how long it lasts and where it happens. Parent Hub says it matters when the behaviour is severe and persistent, shows up in more than one setting, and gets in the way of school and friendships.

ADHD signs fall into three groups. NHG says a child may show mostly one kind of sign, or a mix. Here's how each group can look in a young child, as the sources describe it:

A doctor decides what these signs add up to. Some of them overlap with other conditions. The NHS says doctors may consider autism or anxiety, so see our guides to early signs of autism and sensory processing if those sound familiar. Big meltdowns on their own are covered in our toddler tantrums guide.

At what age doctors assess ADHD

AAP's diagnosis guidelines cover children aged 4 to 18. It says ADHD is hard to diagnose before 4, because young children change so fast. SingHealth's HealthXchange says ADHD can be diagnosed from age 5, but doctors usually prefer to wait until 6 or 7, when a child has more control over their behaviour. HPB's Parent Hub says the signs must have started before age 7 and lasted at least six months.

How ADHD is assessed in Singapore

NUH says a diagnosis should come only after a thorough clinical assessment. That includes an interview with you or your child's main carer. Teachers, early childhood educators and close relatives can add to the picture. AAP says teachers matter here because children aged 4 and up spend many of their waking hours at preschool or school.

Expect questions about your child's behaviour and your family history. AAP says brain scans such as MRIs have little value in diagnosing ADHD in a child.

Treatment for young children

For children under 6, CDC says the AAP recommends behaviour therapy before medicine. The type that works best at this age is parent training in behaviour management. You learn the skills, then use them at home, because CDC says behaviour therapy works best in young children when parents deliver it.

NUH lists parent training, classroom behaviour management, social skills groups and family therapy among the options. KKH's team says parenting skills training helps parents manage ADHD signs better. A doctor may also discuss medicine. NHG says to bring any questions about medicine to your child's doctor.

What helps at home and at preschool

• Give one short instruction at a time. HealthXchange says some very active children can follow only one simple instruction at a time.
• Keep the same basic rules with every carer, grandparents and your helper too. HealthXchange advises setting rules while your child is young and keeping them.
• Use a picture list for daily jobs like getting dressed. HealthXchange suggests simple drawings for children who can't read well yet, and our preschooler routine guide has sample days.
• Praise effort and small wins. HealthXchange says to point out tiny improvements, and NHG suggests rewarding a few behaviours at a time.
• Break sitting tasks into short blocks. The NHS suggests splitting tasks like sitting down to eat into 15 to 20 minute slots, with a break between.
• Plan active play every day, at the playground or along a park connector. The NHS says exercise is a good focus for a child's energy. Ideas are in our active play guide.
• Keep sleep regular, as the NHS advises. Our kids bedtime calculator helps you set a time that fits your child's age.
• Hold hands near roads and pools. AAP says a child with ADHD may not always be aware of dangers and can get hurt easily.

At preschool, NHG suggests teachers seat the child near the front and praise effort. Tell the teacher what works at home. Then you can both use the same words and rewards. Screens a sticking point? Our screen time guide covers setting limits. For early intervention options in Singapore, see our special needs support guide.

When to see a doctor

See your polyclinic doctor or a CHAS GP for a referral if:

• the behaviour has gone on for more than 6 months (AAP)
• it shows up in more than one place, such as home, preschool and the supermarket (HPB's Parent Hub)
• it makes it hard for your child to make friends, get along with others or finish tasks (NHG)
• your child's preschool teacher raises the same concerns, since AAP says teachers give valuable insight
• your child often seems unaware of danger, such as near traffic (AAP)
• you also notice signs of autism or anxiety, which the NHS says doctors consider alongside ADHD

For an emergency, such as a serious injury, go to KKH or NUH Children's Emergency, or call 995 as KKH advises.

Frequently asked questions

What are the signs of ADHD in a preschooler?

Look at the three groups in the table above. In a preschooler that can mean not sitting through meals, climbing on furniture, not waiting a turn or not seeming to listen. HPB's Parent Hub says it matters when they're severe and persistent and turn up in more than one setting. Only a doctor can say what they mean.

Is my child just active, or could it be ADHD?

Lots of young children are just active. The NHS says many under-5s are easily distracted and full of energy, and that doesn't mean ADHD. Being tired or stressed can look similar. If the behaviour is strong, has lasted more than 6 months and shows up everywhere, talk to your doctor.

How is ADHD diagnosed in Singapore?

Start at a polyclinic or CHAS GP. For children aged 6 and below, MOH says they can refer to the Child Development Programme at KKH or NUH. NUH says diagnosis follows a thorough assessment with a parent interview and input from teachers. For children aged 7 and up, MOH says support starts with school counsellors and REACH, with referral to IMH's Child Guidance Clinic when needed.

Can a 3 year old be diagnosed with ADHD?

Not usually. AAP says ADHD is hard to diagnose before 4, because young children change so quickly. HealthXchange says diagnosis is possible from 5, but doctors usually wait until 6 or 7. You can still raise a worry early and get advice on what to do at home.

Will my child grow out of ADHD?

NUH says ADHD can't be outgrown, but children who get help early can still do well at school and in adult life. That's why NUH encourages parents to seek help early rather than wait.

What support is there in Primary 1?

MOH says school counsellors and special educational needs officers support students aged 7 and above at no charge, and bring in REACH when needed. Tell the school about your child's needs before Primary 1 starts. Our Primary 1 checklist covers the rest of the move.
