ADHD

What it is

ADHD is a neurodevelopmental condition involving persistent patterns of inattention, hyperactivity and impulsivity that are beyond what is expected for a person's age and that interfere with daily life across more than one setting (home and school, or work and relationships). It comes in three pictures: mainly inattentive (the quiet daydreamer who loses things and cannot finish tasks, often missed entirely, especially in girls), mainly hyperactive-impulsive (the child who cannot sit, blurts and acts before thinking), and combined.

ADHD is not a discipline problem and not a deficit of intelligence or effort. It is a difference in the brain's systems for attention, motivation and self-regulation. People with ADHD can hyperfocus intensely on what interests them, which is why “but he concentrates on games for hours” is not evidence against the diagnosis; it is part of the picture.

What it can look like

In children: homework that takes three hours and still gets left at home, careless mistakes, forgetfulness, losing belongings, interrupting, fidgeting, climbing, difficulty waiting, and emotional reactions that arrive fast and big. In adults, often undiagnosed: chronic lateness and procrastination, half-finished projects, impulsive decisions, restlessness, difficulty with admin and money, and a long private history of underachieving relative to ability, often misread by others, and by themselves, as laziness or carelessness.

How common is it

ADHD affects around 5% of children, and it continues into adulthood for many of them, affecting roughly 2 to 3% of adults. It is found in every country and culture. The mainly inattentive picture, more common in girls, is often missed, so many people, especially women, are diagnosed only in adulthood after years of struggling.

What causes it

ADHD is strongly heritable, so it often runs in families, and it arises from differences in how the brain's attention and self-regulation systems develop. Factors during pregnancy and birth, such as very low birth weight, can add to the risk. It is not caused by poor parenting, too much sugar, or screens, though a calm, structured environment does help a child cope. It is nobody's fault.

How it is diagnosed

There is no single test. Diagnosis is made by a qualified professional through a careful history of symptoms and their impact across settings, usually gathering information from parents and teachers for children, and ruling out other explanations: anxiety, depression, sleep problems, hearing difficulties, trauma and learning disorders, several of which can also co-occur with ADHD. A diagnosis is justified only when symptoms are persistent, present from childhood, and genuinely impairing, not merely an active temperament.

How it is treated

For school-age children and adults, the evidence supports a combination approach. Behavioural and educational strategies come first for young children and remain a foundation at every age: structure, routines, breaking tasks into steps, clear expectations, and classroom or workplace accommodations. Parent training in behaviour management has strong evidence for children.

Medication is highly effective for many people. Stimulant medications are the best-studied and most effective class for ADHD; non-stimulant options exist where stimulants are unsuitable. These are prescription medicines that require assessment and monitoring by a qualified prescriber; our medications guide explains the classes, and dosing always belongs to the prescriber. Treated well, ADHD shifts from a daily source of failure and shame to a manageable difference, and that shift can change the course of an education, a career and a sense of self.

ADHD in the African context

ADHD is just as common in African children as elsewhere, but it is widely under-recognised here. Restlessness and inattention are often read as naughtiness, poor discipline, or a spiritual problem, and large classes make it harder to spot the quiet, inattentive child. Assessment and specialist services are unevenly spread, and worry about medication runs high. Understanding ADHD as a recognised, manageable condition, rather than bad behaviour, can change a child's whole path through school.

Managing it day to day

Alongside professional support, these approaches help.

• Use structure and routine, with clear, simple steps and visible reminders such as lists, alarms, and calendars.
• Break large tasks into small ones, and tackle them in short, focused stretches with breaks.
• Reduce distractions in the study or work space, and keep important things in one fixed place.
• Protect sleep and physical activity, both of which improve attention.
• Notice strengths, since people with ADHD are often creative, energetic, and able to focus deeply on what interests them.

Helping someone

If your child or someone close to you has ADHD, how you respond matters.

• Learn about the condition, since understanding replaces blame. The behaviour is not chosen.
• Praise effort and small wins, and be clear and consistent rather than harsh.
• Work with the school on simple accommodations, such as seating and extra time.
• Encourage proper assessment and treatment, and offer to help arrange it. Our find a therapist page can help.
• Be patient, and protect the person's confidence, which takes many knocks.
