ADHD is not just about oft-stereotyped ‘squirmy’ kids and people who get distracted easily, says Texas-based Tracy Winter, an executive and leadership coach at Nerd Coach, who specialises in neurodiversity. Instead, ADHD is a complex neurodevelopmental disorder, which manifests in diverse symptoms and behaviours (though the word ‘disorder’ is controversial, points out Winter, who also has ADHD; she prefers to look at it as a “different kind of brain”). The ADHD brain isn’t necessarily flighty, she explains – anatomically, it structurally looks different and functions differently.
