ADHD in adults

ADHD affects around three to four in every hundred adults. It is more common in people who have a sibling or close family member with ADHD, epilepsy, neurodevelopmental conditions, or mental health conditions, and in those with a history of alcohol or drug misuse or an acquired brain injury.

Adult ADHD often looks different from the textbook picture of a restless child. Hyperactivity may have eased, but the inattentive features tend to persist. Many adults describe years of strain that they have learned to mask: missed deadlines, scattered focus, decision fatigue, emotional reactivity, and a sense of underperforming relative to their abilities.

Late diagnosis is common, particularly for women, for those who excelled academically, and for those with quieter, more inattentive presentations. A diagnosis later in life is not a missed opportunity. It is the start of understanding, treatment options, and tailored strategies that can change daily life.

If any of this resonates, an assessment is the most efficient way to clarify whether ADHD or another condition best explains the pattern.
