Attention-deficit/hyperactivity disorder (ADHD) is often discussed in terms of visible traits: fidgeting, distractibility, forgetfulness or restlessness. But those are just the traits we can see.
ADHD is a complex developmental condition rooted in the brain’s motivational, attention and executive-function systems. And much of what looks like “disruptive behaviour” from the outside is often evidence of profound, ongoing internal struggle.
