- So why are so many adults only now realising they have it?
- Does ADHD in adults present in the same way as it does in children?

There are lists circulating online of behaviours that are all too easy to recognise in oneself: getting distracted, putting things off, forgetting an appointment, starting a thousand things without finishing them. It’s natural to wonder whether ADHD hasn’t simply become a fad.
But what exactly is ADHD?
ADHD is the English acronym for attention deficit hyperactivity disorder. It is a neurodevelopmental disorder – that is, one linked to the way the brain develops – which manifests itself from childhood onwards with persistent difficulties with attention, or with hyperactivity and impulsivity, or both, and which often continues into adulthood.
The key word is ‘functioning’. We all get distracted or put things off. ADHD is only diagnosed when these difficulties have persisted for some time, occur in several areas of life and are significant enough to interfere with study, work or relationships.
But you never used to hear about it. Isn’t it a relatively recent condition?
Far from it. Descriptions very similar to those of ADHD can be found in medical texts as early as the late 18th century. In 1775, the German physician Melchior Adam Weikard described people who were easily distracted and inconsistent; in 1798, the Scotsman Alexander Crichton spoke of a ‘mental restlessness’ present from early childhood. In 1902, the English paediatrician George Still described children who were intelligent but unable to sustain their attention or control their impulses.
Those descriptions do not correspond exactly to today’s criteria, but, as a 2015 historical review summarises, ADHD ‘is not a modern invention’. What has changed are the names and our ability to recognise it, not the fact that it exists.
