Attention Deficit Disorder (ADD) has many of the same features as ADHD, so much so that ADD is no longer presented as a separate condition to ADHD in the ICD-11 or the DSM-5. However, some do still diagnose ADD separately and this is generally when someone primarily displays difficulty in concentrating, staying on task, daydreams, shows a lack of attention to detail. What it is claimed that ADDers don’t have is hyperactivity and as much impulsivity. There is a lot of disagreement out there amongst the professionals on this (like so many diagnostic labels around neurodivergence!) and opinion varies widely in different countries.

I’ve put a couple of websites with opposing views on the Information page.
