Attention Deficits/Hyperactivity Disorder (ADHD)

Understanding ADHD

Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects attention regulation, impulse control, and activity levels. It's one of the most commonly diagnosed conditions in children, but it doesn't stop at childhood — many people are first recognised as adults, often after years of unexplained difficulties with focus, organisation, or emotional regulation.

ADHD isn't a single, uniform experience. Clinically, it's understood across three symptom domains — inattention, hyperactivity, and impulsivity — and most people present with a mix of these rather than a "pure" type. A child who struggles to sit still in class and an adult who consistently misses deadlines despite genuine effort may both be describing the same underlying condition, just expressed differently across different life stages and demands.

Why symptoms can look different across people

Presentation varies significantly by age, sex, and individual circumstances. Hyperactivity is often more visible in younger children, while inattentive symptoms can become more prominent — and more disruptive — as academic and workplace demands increase. Girls and women are frequently diagnosed later in life, in part because their symptoms more often present as inattention or internalised struggle rather than the overt hyperactivity that tends to prompt earlier referral. Adults, meanwhile, often arrive at assessment after ADHD has quietly shaped years of work, study, or relationship patterns.

Why a proper assessment matters

Because ADHD shares features with anxiety, learning difficulties, sleep problems, and other conditions, an accurate diagnosis depends on a comprehensive, structured assessment — not a checklist or a single conversation. At the Behavioural Neurotherapy Clinic, assessment draws on clinical interview, standardised measures, and history from relevant sources, so that any recommendations reflect the individual's actual presentation rather than assumptions about what ADHD "should" look like.

Treatment is rarely one thing on its own

Current best-practice guidelines recommend a multimodal approach — combining strategies rather than relying on any single intervention in isolation. Depending on the person, this may include medication, psychological therapy such as CBT, family-focused support, and practical strategies for daily functioning. What works well for one person may not suit another, which is why treatment planning follows assessment rather than preceding it.
