What ADHD is, in short

ADHD (attention-deficit/hyperactivity disorder) is a neurodevelopmental condition in which ongoing patterns of inattention, hyperactivity or impulsivity begin in childhood and interfere with daily life. It is recognised in both the DSM-5 and ICD-11.

ADHD isn't a sign of low intelligence or a lack of effort, and it is independent of IQ. It often continues into adulthood, where hyperactivity tends to become inner restlessness while disorganisation and time-management problems come to the fore.

Worldwide, about 2.8% of adults meet criteria for ADHD, averaged across 20 countries in the WHO World Mental Health Surveys.

Screened positive? Note real examples from work and home, recall whether they started in childhood, and book a GP or doctor appointment. ADHD is very manageable with the right support.
