While it is well established that childhood ADHD may continue into adulthood, new research by King's College London suggests that for some people the disorder does not emerge until after childhood.

Attention-deficit/hyperactivity disorder (ADHD) is a developmental disorder marked by inattention, hyperactivity and impulsivity and is one of the most common behavioural disorders in children. It is widely believed that adult ADHD is the continuation of the disorder from childhood.

However, researchers from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's found that nearly 70 per cent of the young adults with ADHD in their study did not meet criteria for the disorder at any of the childhood assessments. Adults with this 'late-onset' ADHD had high levels of symptoms, impairment and other mental health disorders.

Published today in JAMA Psychiatry, these findings have important implications for our understanding of ADHD, as ADHD that onsets in adulthood could have different causes to childhood ADHD.
