ADHD (attention deficit hyperactivity disorder) is a developmental difference in how attention, activity level and impulse control are regulated. It is not a matter of effort or discipline, and it doesn't reflect intelligence.
The three broad presentations
ADHD is generally described in three presentations, and people can shift between them over time:
- Predominantly inattentive: difficulty sustaining focus, losing track of instructions, misplacing things, appearing to daydream
- Predominantly hyperactive-impulsive: restlessness, difficulty staying seated, interrupting, acting before thinking
- Combined: features of both
How it looks in children
In a classroom, ADHD often surfaces as unfinished work despite clear ability, instructions that need repeating, or a child who is bright in discussion but disorganised on paper. Homework can take far longer than it should and often ends in frustration for everyone.
Hyperactivity is more visible and so tends to be identified earlier. Quietly inattentive children, more often girls, are frequently described as dreamy or careless rather than struggling, which is one reason their difficulties are recognised later.
How it looks in adults
Adults rarely describe themselves as hyperactive. It shows up instead as internal restlessness, difficulty settling, or a habit of taking on more than is manageable.
Common day-to-day patterns include chronic lateness, unfinished projects, difficulty starting tasks that aren't urgent or interesting, forgotten commitments, and long periods of intense focus on something absorbing followed by exhaustion. Many adults have built elaborate systems to compensate, and only seek assessment when circumstances change and those systems stop holding.
What an assessment involves
A psychological ADHD assessment is not a single test. It's a structured process that gathers information from several sources so that a pattern, rather than a snapshot, can be seen:
- A detailed developmental, educational and family history
- Standardised rating scales completed by the individual and, where relevant, parents and teachers
- Assessment of attention, working memory and related cognitive skills
- Review of school reports or workplace observations where available
- Consideration of other explanations: anxiety, low mood, sleep difficulties, learning difficulties or hearing problems can all affect attention
Why the process is thorough
Attention difficulties are not specific to ADHD. A child who sleeps badly, an anxious teenager, or an adult under sustained stress can all present with similar concentration problems. A careful assessment is what distinguishes between these possibilities.
The outcome is a clear written report explaining what was found, what it means in practical terms, and specific recommendations for home, school or work, including onward referral where medical input is appropriate.
Support after an assessment
An assessment is a starting point rather than a conclusion. Support may include structured strategies for organisation and task initiation, behaviour approaches for younger children, work with the school on classroom accommodations, and counselling for the self-esteem difficulties that often accompany years of being told to simply try harder.
Many people describe an accurate assessment as a relief: the difficulty finally has a name, and the plan that follows can be built around how their attention actually works.
