Types ADHD in adults
The types of ADHD: three presentations of one condition
ADHD is one condition with three "presentations", and which one fits depends on where your symptoms fall between two clusters: inattention (focus, organisation, follow-through) and hyperactivity-impulsivity (restlessness, acting before thinking). The current manual replaced the older idea of separate "types" with presentations, precisely because they are not fixed — the one that fits you can change across your life.
What people still call "ADD" is the inattentive presentation. If any of this sounds familiar, the adult ADHD screening based on the WHO ASRS is a quick, private first step toward an assessment.

The main types, one by one
- Predominantly inattentive presentation
- The focus-and-organisation side without obvious hyperactivity — what used to be called ADD. Easy to miss because it is quiet, and disproportionately under-diagnosed in women and girls. Read more →
- Predominantly hyperactive-impulsive presentation
- The restless, act-first side — fidgeting, difficulty staying seated, interrupting, impatience, and impulsive decisions — with fewer inattentive symptoms. The most externally visible presentation, and the one most often spotted early in childhood.
- Combined presentation
- Enough symptoms from both clusters — inattention and hyperactivity-impulsivity — to meet the threshold for each. The most commonly diagnosed presentation overall.

you which one fits — a screening is a helpful first step, not the last word.
