I have had the same conversation dozens of times. A patient — usually in their 30s or 40s, often a woman — comes in for something unrelated, and during the consultation something triggers a question. Had they ever been assessed for ADHD? The response is almost always some version of: "Isn't that for hyperactive boys?"
No. It is not.
ADHD (Attention Deficit Hyperactivity Disorder) is a neurodevelopmental condition affecting approximately 3–4% of adults. It presents very differently in adults than in children, very differently in women than men, and it was dramatically underdiagnosed in African children who grew up in educational systems where ADHD was either not recognised, or where children — particularly girls — who struggled with attention were labelled as "lazy," "unfocused," or "not trying hard enough."
The consequence is a generation of African adults who have spent decades developing coping strategies for something they did not know had a name.
How ADHD in adults looks different from the stereotype
The public image of ADHD is a disruptive seven-year-old boy who cannot sit still. This image captures one presentation of childhood ADHD — and it has caused enormous harm by making the condition essentially invisible in girls, in quiet inattentive children, and in adults.
Adult ADHD commonly looks like:
- Starting many projects and finishing few
- Difficulty with time management — consistently underestimating how long things take, being late despite genuine effort not to be
- Hyperfocus — the ability to concentrate intensely on something interesting for hours, contrasted with the inability to concentrate at all on something uninteresting
- Difficulty beginning tasks that feel boring or overwhelming — "task paralysis"
- Emotional dysregulation — intense emotional responses, quick temper, quickly moved to tears
- Rejection sensitive dysphoria — intense emotional pain in response to perceived rejection or criticism, disproportionate to the situation
- Difficulty with organisation, losing things, forgetting appointments
- Talking over people, finishing others' sentences, difficulty waiting in conversations
- In women particularly: internalised symptoms — anxiety, depression, perfectionism as a compensatory strategy, chronic exhaustion from "masking"
Why ADHD was missed in African children
Cultural factors: In many African educational contexts, children with attention difficulties were viewed through a lens of discipline rather than neurology. A child who could not focus was not trying hard enough. A girl who daydreamed was lazy. Strict educational environments sometimes actually masked ADHD symptoms through external structure — children managed at school and fell apart at home or in unstructured settings.
Gender bias: Girls with ADHD more commonly present with inattentive ADHD rather than hyperactive-impulsive ADHD. They are quieter, less disruptive, more likely to be daydreaming than disrupting. They are dramatically less likely to be referred for assessment.
Diagnostic criteria bias: Early diagnostic criteria for ADHD were developed from research predominantly in white male children. Presentations that differed from this template were less likely to be recognised.
Under-resourced educational systems: Many children in African countries grew up in schools without educational psychologists, SENCO support, or assessment pathways even for children showing clear signs of learning difficulties.
The result: a generation of African adults — particularly women — who grew up hearing that they were bright but lazy, that they had potential they were wasting, that they needed to try harder. Who compensated through enormous effort and intelligence, sometimes reaching high levels of professional achievement — while experiencing the private exhaustion of a brain working twice as hard as neurotypical peers to achieve the same results.
Case study: Amara, finally understood at 36
Amara, 36, a solicitor from Ghana based in London, came to see me initially for anxiety. She described constant overwhelm, difficulty managing her workload despite long hours, feeling like she was "always drowning" despite being technically excellent at her job.
As we talked, a pattern emerged. She had always been like this — she had just always found ways around it. At school she had been "the smart one who needed to work harder." At university she had pulled all-nighters and relied on adrenaline-fuelled deadline pressure to complete work. As a solicitor she had developed elaborate systems — multiple calendars, constant lists, alerts for everything — that exhausted her to maintain but without which she could not function.
She described reading the same paragraph 10 times before it would stick. Sitting at her desk for three hours unable to begin a task she knew exactly how to do. Being interrupted by a colleague and losing an entire morning's work from her working memory. Being told she was "scattered" in feedback.
I referred her for a private ADHD assessment — NHS waiting times in her area were over 2 years. The assessment confirmed combined-type ADHD. She began methylphenidate.
"The first morning I took it," she told me, "I sat at my desk, opened a document, and wrote for three hours. I cried. I had never known what that was like. I thought everyone had to fight this hard."
Getting diagnosed — the pathway
NHS pathway: Referral from GP to adult ADHD service. Waiting times currently range from 6 months to over 3 years depending on area. The Right to Choose scheme allows patients to access alternative NHS-commissioned ADHD providers with shorter waits — ask your GP specifically about this option.
Private assessment: Available within weeks. Typically costs £600–1,200 for a full assessment. A private diagnosis can be "shared care" with your NHS GP for prescription management — though some GPs are reluctant and this requires negotiation.
What assessment involves: Structured clinical interview, symptom rating scales (self-report and ideally informant report from someone who knows you well), review of childhood functioning (school reports if available are helpful), and ruling out other conditions that can mimic ADHD (anxiety, depression, thyroid dysfunction, sleep disorders).
Treatment
Medication:
Stimulants (methylphenidate — Ritalin, Concerta; lisdexamfetamine — Vyvanse): First-line treatment with strong evidence. Work by increasing dopamine and noradrenaline in the prefrontal cortex — the brain's executive function centre. Many people describe the effect as "everything slowing down" or "being able to think in a straight line."
Non-stimulants (atomoxetine, guanfacine): Used when stimulants are contraindicated or not tolerated. Slower onset, may be preferable for people with anxiety or substance use history.
ADHD Coaching: Working with a coach trained in ADHD to develop systems, structures, and strategies tailored to how your brain works. Evidence-based and highly effective alongside medication.
CBT for ADHD: Adapted CBT addresses the emotional and cognitive consequences of ADHD — rejection sensitivity, shame, perfectionism, procrastination — alongside practical skills.
