Expert ADHD assessment in Sydney
Professional ADHD assessment and diagnosis for children and adults in Sydney. Experienced GPs with specialist training. No GP referral needed.
Understanding ADHD
ADHD isn’t just about struggling to sit still. Among those seeking assessment, around 90% report difficulty sustaining focus: losing track mid-conversation, re-reading the same paragraph, or forgetting why they walked into a room. About a third experience hyperactivity or impulsivity that disrupts daily routines.
For children, it can look like restlessness in the classroom, difficulty following instructions, or emotional outbursts that seem disproportionate. For adults, it often hides behind years of coping strategies, until those strategies stop working.

The hidden cost of living with ADHD
For busy professionals, untreated ADHD creates consequences that compound over time. The World Health Organization estimates that adults with unmanaged ADHD lose an average of 22 days of productivity every year. Not from absence, but from the daily friction of missed deadlines, derailed meetings, and tasks that never quite get finished.
The numbers tell a harder story: people with untreated ADHD are 60% more likely to be let go from a job and three times more likely to quit impulsively. Open-plan offices, constant context-switching, and back-to-back meetings create environments that work against the ADHD brain, even for high achievers who’ve spent years masking their symptoms.
A diagnosis isn’t a label. It’s the beginning of understanding why things have felt so hard, and what to do about it.

A practice built on trust, based in Sydney
Headfirst was founded by GPs who saw a gap: families and adults across Sydney waiting months (sometimes years) for ADHD assessment through overstretched public services.
Every assessment is led by an experienced GP with specialist training in neurodevelopmental conditions. We follow AADPA evidence-based guidelines, the Australian standard for ADHD diagnosis, with no GP referral needed to get started.
We take the time to listen, explain, and support. Because that’s how good medicine works.
