ADHD in children: Spotting the signs early

Most children are energetic, distractible or impulsive from time to time (especially when they’re tired, hungry or overstimulated).

However, when these behaviours are persistent, show up across more than one setting (like home and school) and start interfering with learning, routines or relationships, it may be a sign of ADHD.

ADHD is a common neuro-developmental condition marked by ongoing patterns of inattention, hyperactivity and impulsivity that can affect a child’s day-to-day functioning and development.

It is often diagnosed at school-going age, typically around six, and may continue well into adulthood.

According to Dr Doshen Naidoo, paediatrician at Mediclinic Pietermaritzburg, distinguishing between spirited normal childhood behaviour and ADHD normally come down to three main factors: frequency, intensity and impact.

“Most children will have moments of distraction or high energy, but children with ADHD experience these symptoms consistently across multiple environments for a period of at least six months,” Dr Naidoo said.

When it’s more than ‘just a phase’

A common misconception that delays support is the belief that a child will ‘outgrow it’ or that the issue is teacher- or school-specific. Some families may also resist intervention due to fears that medication will cause dependency or may affect the temperament of their child.

However, Dr Naidoo notes that concern often becomes more apparent when a teacher flags that a child is not achieving their full academic potential. This is typically noted alongside difficulty completing tasks timeously or neatly, excessive fidgeting, or classroom disruption. In these cases, a professional assessment is advised, particularly because specific learning disorders can present with similar symptoms.

The cost of missing ADHD

When ADHD is left undiagnosed, children can fall into a cycle of failure. This is where neurobiological challenges are mistaken for character flaws such as laziness, stubbornness or defiance. Over time, children may internalise these labels, which can affect learning, social connection and overall emotional wellbeing.

Children may miss key information. This can include struggling to follow directions and leaving tasks incomplete, or to an increased risk of grade failure, disciplinary action and disengagement from school. Socially, impulsivity and difficulty regulating behaviour in real time can lead to peer rejection, isolation, or conflict at home. Emotionally, the cumulative impact of repeated correction and shame can contribute to anxiety, depression and risky coping behaviours later on.

Why early support matters

Early diagnosis and support can be powerful because it creates a ‘window of opportunity’ -allowing families and educators to intervene before patterns become deeply ingrained. Early identification can protect self-esteem, improve parent-child relationships by shifting responses from punishment to supportive strategies, and reduce the risk of mental health complications down the line.

It also helps children build the executive functioning skills they need as schoolwork becomes more complex, while improving the chances of healthier peer relationships and more consistent classroom success.

What an ADHD assessment involves

This is not a single test, but a comprehensive clinical evaluation. Families can start by speaking to a paediatrician or GP with an interest in ADHD, who can screen and refer when needed.

A thorough evaluation may include:

• Clinical interviews with caregivers and direct observation of the child
• Rating scales completed by parents and teachers (to assess symptoms at home and school)
• A medical examination to rule out other causes (such as hearing/vision problems, thyroid issues or sleep disorders)
• Review of school reports and teacher feedback (as symptoms must appear in more than one setting)
• Optional psychometric testing to identify learning disorders that may contribute to difficulties

An official diagnosis may be made by specialists, including a child psychiatrist, paediatrician, clinical or educational psychologist, or a paediatric neurologist in special cases.

The role of schools and teachers

Teachers are often the first to notice when behaviour differs from peers in intensity and frequency, particularly in the structured classroom environment. Schools can play an important role in gathering information for clinicians and putting supportive strategies in place.

Practical classroom approaches may include seating adjustments to reduce distractions, movement breaks, sensory tools, breaking tasks into smaller chunks, using visual aids, and giving concise instructions backed up in writing. Teachers can also protect a child’s self-esteem through positive reinforcement, private redirection and stigma-reducing classroom culture. Where appropriate, schools may facilitate exam accommodations such as extra time or quieter venues.

Reassurance for parents

Dr Naidoo emphasises that feeling anxious, guilty or overwhelmed after a diagnosis is normal – but a diagnosis does not change who a child is.

“A diagnosis is not a label that limits a child, it’s a map that helps explain how their world works,” he says.

He concludes that ADHD is a ‘performance gap’, not a reflection of intelligence, and that support can unlock a child’s strengths. A formal diagnosis can also open doors to support such as school concessions, medical aid benefits, and specialised therapies.

Most importantly, early identification can help prevent years of learned helplessness and low self-esteem. With the right support, children with ADHD can thrive at school, at home and in their relationships.
