ADHD Meaning / History
not a modern inventionADHD has been described for over 200 years.
Despite the headlines, ADHD isn't a product of screens or modern life. Physicians have been describing this exact pattern of restless, inconsistent attention since the 18th century — they just kept changing its name.
A "disease of attention."
In 1798, the Scottish physician Sir Alexander Crichton described people with a "incapacity of attending with a necessary degree of constancy to any one object" — a mental restlessness he called the disease of attention, noting it usually eased with age. It's a strikingly modern description for the 18th century. Even earlier, thinkers from Hippocrates to John Locke had noted minds that couldn't keep from straying.
In 1844, the German physician Heinrich Hoffmann captured it in a children's story — "Fidgety Phil," a boy who squirms, won't listen, and can't sit still — an accidental portrait of ADHD that still rings true.
From the clinic to the pharmacy.
In 1902, British paediatrician Sir George Frederic Still delivered landmark lectures on children who were impulsive and inattentive despite normal intelligence and supportive homes — concluding the trait was innate, and noting it appeared more often in boys. He called it, in the language of the day, a "defect of moral control." In 1932, Kramer and Pollnow described a "hyperkinetic disease."
Then, in 1937, came an accident of history: Dr. Charles Bradley observed that a stimulant medication unexpectedly improved behaviour and schoolwork in some children — a discovery made decades before the condition even had its modern name.
Four names for one pattern.
1968 — Hyperkinetic reaction
The DSM-II gave it its first American Psychiatric Association listing, framed as a childhood condition thought to fade by adolescence.
1980 — ADD
The DSM-III renamed it Attention Deficit Disorder, with or without hyperactivity — putting attention, not just movement, at the centre.
1987 — ADHD
The revised DSM-III-R settled on Attention-Deficit/Hyperactivity Disorder — the name we still use.
2013 — DSM-5
The current criteria recognised ADHD as lifelong, formally acknowledging adults and raising the onset age. Its earlier names had included "minimal brain dysfunction" along the way.
History questions.
No. Physicians have described the same pattern of restless, inconsistent attention since at least 1798, and arguably far earlier. What's modern is the name and the diagnostic criteria — not the condition.
Sir Alexander Crichton described it in 1798 as a "disease of attention." The first detailed clinical account is usually credited to Sir George Frederic Still's 1902 lectures.
As understanding grew, the emphasis shifted — from "defect of moral control" to "minimal brain dysfunction" to ADD to ADHD — each name reflecting the science of its era. The current name dates to 1987.
Essentially yes. "ADD" was the official name from 1980–1987; today all presentations fall under ADHD, including the inattentive presentation many people still informally call ADD.
