What is ADHD?
ADHD (ICD-11 6A05) is a common, recognised difference in how a child's brain manages attention, activity and impulse control — not bad behaviour or low intelligence. It appears as inattentive, hyperactive-impulsive or combined patterns across settings. Diagnosis is made only by qualified clinicians, and children thrive with the right support.
Read the answer AnswerWhat is the difference between ADHD and Autism Spectrum in young children?
ADHD and Autism Spectrum are distinct profiles often confused in young children. ADHD centres on attention, impulse control and activity levels, while Autism Spectrum centres on social communication, connection, play and sensory experience. They can look alike early on and sometimes occur together in the same child, which is why a single behaviour rarely tells the whole story. Neither is a flaw — each is a profile that, understood early through a developmental review, opens the door to the right support.
Read the answer AnswerADHD vs Cerebral Palsy in Young Children
ADHD and cerebral palsy are very different conditions in young children. ADHD affects attention, impulse control and activity levels, while physical coordination is usually typical. Cerebral palsy is a non-progressive movement and posture condition caused by early brain differences, with signs often visible in infancy such as stiff or floppy muscles and delayed motor milestones. One is mainly about focus and behaviour; the other is mainly about movement — and a clinician review distinguishes them.
Read the answer AnswerWhat is the difference between ADHD and Down Syndrome in young children?
ADHD and Down syndrome are very different. Down syndrome is a genetic condition caused by an extra chromosome 21, present from birth and usually recognised early, affecting physical features, growth and learning. ADHD is a neurodevelopmental pattern of attention, activity and impulse control that emerges over the early-to-school years, with no birth test or physical sign. One is identified by genes, the other by behaviour observed over time — and the two can sometimes co-occur.
Read the answer AnswerWhat is the difference between ADHD and Global Developmental Delay in young children?
ADHD and Global Developmental Delay describe different journeys in young children. ADHD is mainly a difference in attention, activity and impulse control, with thinking and milestones usually on track. GDD means a child is slower across several developmental areas at once — talking, moving, problem-solving and self-care — and is a term used before age five. The two can overlap, so a whole-child assessment matters rather than a checklist label, and both respond well to early, individualised support.
Read the answer AnswerWhat is the difference between ADHD and Hearing Impairment in young children?
ADHD and hearing impairment can look alike in young children — both may seem not to listen or have delayed speech — but they are very different. ADHD is about regulating attention, activity and impulses while hearing works normally; hearing impairment is about reduced access to sound while the wish to attend is intact. Because the signs overlap, hearing should always be checked first before attention is considered.
Read the answer AnswerWhat is the difference between ADHD and Intellectual Disability in young children?
ADHD and intellectual disability are different. ADHD mainly affects attention, impulse control and activity levels — a child can be bright yet struggle to focus, wait or sit still, with learning ability intact. Intellectual disability affects overall learning, reasoning and daily self-care skills, which develop more slowly across the board. A child can have one, the other or both, and only a qualified clinician can distinguish them through a whole-child assessment.
Read the answer AnswerWhat is the difference between ADHD and Sensory Processing Differences?
ADHD is mainly about how a young child's brain manages attention, impulses and activity across many settings, while sensory processing differences are about how a child takes in and responds to everyday sensations like sound, touch and movement. They can look similar — a fidgety, distractible or restless child — and sometimes overlap, but the underlying reason differs and shapes the support that helps. In young children neither should be labelled hastily; persistent patterns across settings are a reason for a gentle developmental review, not alarm.
Read the answer AnswerWhat is the difference between ADHD and Specific Learning Disability in young children?
ADHD and Specific Learning Disability are different. ADHD affects attention, activity and impulse control across most settings; SLD affects one academic skill — usually reading, writing or maths — despite good effort. A child can have either or both. Neither reflects intelligence, and in young children many patterns are simply development unfolding; a clear SLD picture usually emerges around ages 6–8.
Read the answer AnswerWhat is the difference between ADHD and Speech and Language Delay?
ADHD and speech and language delay are different developmental threads. ADHD affects how a child manages attention, activity and impulses, while a language delay affects how a child understands and uses words. ADHD is usually considered from school age, whereas language delays can be noticed and supported in the toddler years. The two can sometimes overlap, so a whole-child review is the best way to understand which is at play. Neither is a verdict, and both respond well to early support.

Can you tell if a 6–9-month-old has ADHD?
At six to nine months, ADHD cannot be diagnosed — a baby's attention and activity are still developing normally. Clinicians don't evaluate for ADHD before about age 4. Track general milestones instead, and have any genuine developmental delay checked early.
Read the answer AnswerWhat are the early signs of ADHD?
Early ADHD signs are inattention, hyperactivity and impulsivity that are stronger and more persistent than in same-age children, appear before age 12, and show across more than one setting. Under age 4–5 normal energy overlaps heavily, so a persistent, disruptive pattern matters most — and ADHD is never diagnosed from a checklist alone.
Read the answer AnswerEarly signs of ADHD in a 12-to-18-month-old
ADHD cannot be diagnosed in a 12-to-18-month-old — high energy and short attention are normal toddler behaviour, not early ADHD. ADHD becomes a meaningful question only from around school age. At this stage, watch broad development — communication, connection, play and movement — and raise any worry early through a general developmental check.
Read the answer AnswerEarly Signs of ADHD in an 18-to-24-Month-Old
ADHD cannot be diagnosed in an 18-to-24-month-old — high activity, short attention and impulsiveness are normal toddler traits, and ADHD (ICD-11 6A05) is recognised only later, usually around school age. At this age, watch overall development in communication, play, sleep and behaviour, and share any worries at a routine developmental check rather than looking for ADHD signs.
Read the answer AnswerWhat are the early signs of ADHD in a 2-year-old?
ADHD is not diagnosed at age two — restlessness, impulsivity and short attention are normal toddler behaviour. Reliable ADHD assessment begins around 4–6 years when traits persist across settings and affect daily life. For any concern at two, a general developmental check is the right, reassuring first step.
Read the answer AnswerWhat are the early signs of ADHD in a 3-to-6-month-old?
ADHD cannot be identified in a 3-to-6-month-old and there is no infant signs list to watch for. ADHD is a sustained pattern recognised only from the preschool years. At this age, track normal milestones — social smiles, eye tracking, head control, reaching — and see a clinician for any general developmental concern.
Read the answer AnswerWhat are the early signs of ADHD in a 3-year-old?
At three, high energy and short attention are usually normal, and ADHD is not formally diagnosed this young. Watch for restlessness, impulsivity and inattention that are clearly beyond same-age children and persist across home and playgroup — a pattern worth a gentle developmental check, not a cause for alarm.
Read the answer AnswerWhat are the early signs of ADHD in a 4-year-old?
At four, lively energy, short attention and impulsiveness are largely normal. ADHD is considered only when inattention, hyperactivity or impulsivity are far stronger than peers, persist across home and playgroup, and disrupt daily life. A formal diagnosis is rarely made this young, but noticing a clear pattern early means support can begin sooner.
Read the answer AnswerWhat are the early signs of ADHD in a 5-year-old?
Many five-year-olds are active and distractible — that's normal. ADHD is considered when inattention, hyperactivity and impulsivity are stronger than same-age peers, appear across home and school, last six months or more, and disrupt learning or friendships. At five this is a reason to watch and screen, not to label — only a clinician confirms it.
Read the answer AnswerWhat are the early signs of ADHD in a 6-to-9-month-old?
ADHD cannot be identified in a 6-to-9-month-old — there is no infant ADHD signs list, and busy, distractible baby behaviour is normal. ADHD is usually considered only from around 4–5 years, when attention and activity can be compared with peers. For now, simply track general milestones and book a routine developmental check if anything worries you.
Read the answer AnswerWhat are the early signs of ADHD in a 6-year-old?
ADHD in a 6-year-old appears as a consistent pattern of inattention, hyperactivity or impulsivity that is more than same-age peers, seen across home and school, and interfering with learning, friendships or routines. Occasional fidgeting is normal — persistence across settings is the cue for a clinician-led check.
Read the answer AnswerEarly Signs of ADHD in a 9-to-12-Month-Old
ADHD cannot be identified in a 9-to-12-month-old and there is no early-signs list at this age — high energy, wriggling and short attention are normal infant behaviour. ADHD (ICD-11 6A05) is recognised only from around school age. For any concern now, the right step is a general developmental check, not an ADHD-specific one.
Read the answer AnswerWhat are the early signs of ADHD in a newborn?
ADHD cannot be identified in a newborn — attention, impulse control and activity regulation only develop and become observable over the early years, and ADHD is usually recognised from around school-entry age. Newborn fussiness, wakefulness and high activity are normal. Focus on nurturing care and routine developmental checks instead.
Read the answer AnswerWhen should I worry that my 12–18 month old might have ADHD?
At 12–18 months ADHD cannot be diagnosed, and high energy or short attention is normal toddler behaviour. Rather than ADHD signs, watch milestones — connection, communication, play and movement. A general developmental check, not ADHD screening, is the right next step, and only a clinician can assess.
