ADHD (attention-deficit/hyperactivity disorder)

A common, lifelong difference in how the brain manages attention, impulses, and activity — often missed until adulthood, and very manageable with the right support.

What it is

ADHD is a neurodevelopmental difference, not a character flaw or a matter of willpower. The brain's systems for regulating attention, impulses, and activity work differently — present from childhood and frequently continuing into adult life, even when it was never noticed earlier.

Common signs

Trouble sustaining attention on tasks that aren't novel or urgent, and losing track of details
Starting many things but struggling to finish, or leaving things until the last minute
Restlessness, fidgeting, or a constant sense of being 'driven by a motor'
Acting or speaking before thinking it through; interrupting or blurting things out
Time-blindness, forgetfulness, and difficulty getting organized
Strong, fast-changing emotions — adults often notice this more than hyperactivity

Good to know

Many people aren't identified until adulthood, often after their own child is diagnosed. ADHD frequently travels with anxiety, depression, or sleep problems, and stress or poor sleep can mimic it — so a screening tool (like the ADHD self-check on this site) is only a starting point, never a diagnosis.

What helps

A proper assessment by a qualified professional is the first step — a family doctor can refer you. Support usually blends practical strategies and environmental changes (routines, reminders, breaking tasks into small steps) with, for some people, medication and/or coaching or therapy. What helps is individual, and it's reasonable to try a few approaches.

When to seek help

If attention, restlessness, or impulsivity are getting in the way of work, school, relationships, or your wellbeing — or you've struggled with these for as long as you can remember — it's worth talking to a family doctor about an assessment.
