ADD vs ADHD: What's the Difference?

By Jess, Mental Health Writer 12 July 2026 5 min read

You’ll still hear people talk about “ADD” and “ADHD” as if they’re two different conditions. Here’s the simple answer: they’re not — “ADD” is just an older name. But the distinction people are reaching for is real, so it’s worth clearing up.

The short version

ADD (attention-deficit disorder) is an outdated term. It was used in the past to describe people who had attention difficulties without hyperactivity. Today, the umbrella term for all of it is ADHD (attention-deficit/hyperactivity disorder), and what used to be called “ADD” is now recognised as one of ADHD’s presentations.

So if someone says they “have ADD,” what they almost always mean is the inattentive presentation of ADHD.

Why the name changed

The terminology was updated as understanding improved. Clinicians recognised that attention problems and hyperactivity-impulsivity are part of the same underlying condition, appearing in different combinations. Rather than two separate diagnoses, the current diagnostic manual (DSM-5) describes ADHD with three presentations:

  • Predominantly inattentive (what people mean by “ADD”)
  • Predominantly hyperactive-impulsive
  • Combined

Why people still say “ADD”

The old term stuck around because it usefully captured something: not everyone with ADHD is hyperactive. Many adults — especially women — have the quiet, inattentive kind and don’t relate to the “bouncing off the walls” stereotype. “ADD” felt like a better fit. The condition is the same; only the label has been updated.

What matters more than the label

Whether you call it ADD or ADHD, the important thing is whether attention, organisation and self-regulation difficulties are affecting your life — and if so, getting a proper assessment. Try our free ADHD self-check or learn about ADHD assessment.
