The worst acronym in the world.
There is no deficit of attention, trust me. Have you ever seen someone with ADHD doing something they’re interested in? There is no stopping them once they’re in that space, they could go for hours without so much as stopping to blink. Hyperfocus is one hell of an experience.
So then what is a better acronym? There have been many suggestions over the years but Dr. Edward Hallowell and John Ratey came up with VAST, Variable Attention Stimulus Trait.
