ADHD: the Australian clinical guide.
ADHD is not a discipline problem or an attention deficit in any literal sense. It's a difference in how the brain regulates attention, motivation, and executive function — driven by dopamine and norepinephrine systems that work differently to the neurotypical default.
The three-ish presentations.
DSM-5 recognises three "presentations" of ADHD: predominantly inattentive, predominantly hyperactive-impulsive, and combined. In reality these are snapshots of the same underlying neurotype expressing itself differently depending on age, environment, hormones, stress, and masking capacity. Most adults who were flagged as hyperactive kids become inattentive-presenting adults. Most women and AFAB folks were missed entirely.
The core isn't inattention — it's interest-based nervous system regulation. ADHDers can absolutely pay attention, sometimes ferociously. They just can't summon that attention on demand for tasks the brain has flagged as boring, abstract, or low-stakes. This is neurological, not a character flaw.

Executive function
Working memory, task initiation, planning, emotional regulation. Not broken — running on different hardware with different demands.
02
RSD
Rejection Sensitive Dysphoria. Not in the DSM, but universally recognised by ADHDers. Perceived rejection lands like a physical blow.

Hyperfocus
The flip side of distractibility. When the interest lights up, ADHDers can work for twelve hours straight and forget to eat.
