Is this actually ADHD?
Most people who end up researching ADHD diagnosis have spent a long time wondering if something is off. Not lazy, not disorganised, not bad with time — just genuinely struggling in ways that feel out of proportion to the effort you put in. That’s a common starting point and it’s worth taking seriously.
ADHD is a neurodevelopmental condition that affects how the brain regulates attention, impulse control and activity. It’s not a character flaw and it doesn’t mean low intelligence. Many people with ADHD are high-functioning in some areas and seriously struggling in others, which is exactly why it gets missed for so long.
In adults it tends to look less like the hyperactive kid bouncing off the walls and more like chronic disorganisation, emotional dysregulation, difficulty finishing things, an inability to switch off, or years of feeling like you’re working twice as hard as everyone else for the same result.
Inattentive symptoms
- Difficulty sustaining attention on tasks or conversations
- Frequently losing things: keys, phone, documents
- Making careless mistakes despite real effort
- Easily distracted by external noise or internal thoughts
- Difficulty finishing projects once the initial interest fades
- Forgetting appointments, calls, obligations
- Poor time management and chronic lateness
Hyperactive and impulsive symptoms
- Internal restlessness even when sitting still
- Difficulty sitting through long meetings or events
- Interrupting conversations or talking over people
- Impulsive spending or decision-making
- Emotional dysregulation, quick to frustration or tears
- Hyperfocus: completely absorbed in certain things, unable to stop
- Difficulty relaxing or switching off mentally
Women are particularly likely to present with inattentive symptoms, which are subtler and more easily attributed to anxiety or depression. Many women aren’t diagnosed until their 30s or 40s, often after a child in the family is assessed.

Book an ADHD assessmentBefore assuming it’s ADHD
Several conditions produce very similar symptoms. Anxiety, depression, sleep apnoea, thyroid problems and iron deficiency can all look like ADHD and frequently co-occur with it. A good assessment looks at the full picture rather than ticking a checklist. That’s one reason why going through a GP first is the right move.
Who can diagnose ADHD in Australia?
Historically, only psychiatrists and paediatricians could formally diagnose ADHD and initiate medication in Australia. That’s changing state by state.
In Queensland, from December 2025, GPs who have completed an accredited ADHD training program can now assess, diagnose and prescribe medication for adult ADHD without needing to refer to a psychiatrist first. This is a significant change. What previously took 6 to 24 months on a psychiatrist waitlist can now often be resolved within one or two GP appointments.
Queensland GP pathway: what changed in December 2025
Trained GPs in Queensland can now diagnose adult ADHD and prescribe stimulant medication independently. This doesn’t apply to every GP, only those who have completed the RACGP accredited training program. For straightforward adult presentations it can dramatically reduce the time and cost of getting diagnosed.
For complex cases, co-occurring conditions like autism, or presentations that need more specialist input, referral to a psychiatrist or psychologist remains the right pathway. Your GP will tell you which route applies to your situation.
How the process works, step by step
-
Start with your GP
Book a long appointment, 30 minutes if possible, and tell them you want to discuss ADHD. Be specific about how your symptoms affect your daily life: work, relationships, finances, functioning. The more concrete you can be, the more useful the conversation.
-
Your GP takes a detailed history
They’ll go through your current symptoms, how long they’ve been present, any childhood history you can recall, school reports if you have them, mental health history, family history, and other conditions that might explain what you’re experiencing.
-
Ruling out other causes
Blood tests are usually ordered to check for thyroid issues, iron deficiency and other conditions that can mimic ADHD. This is a normal and important part of the process.
-
Diagnosis or referral
In Queensland, trained GPs can now make the diagnosis and initiate treatment for straightforward adult presentations. For complex cases your GP will refer you to a psychiatrist or psychologist. Either way, they’ll explain the reasoning and what comes next.
-
Treatment and ongoing care
If ADHD is confirmed, you’ll discuss treatment options together. Medication works well for most people but it’s not the only path. Psychological strategies and coaching are effective too, particularly for managing the practical day-to-day challenges. Your GP handles ongoing prescriptions and monitoring.
What to bring to your first appointment
Coming prepared makes a real difference. Write down your symptoms in your own words before you go, with specific examples of how they affect your life. “I can’t stay focused” is less useful than “I’ve missed three deadlines this month because I couldn’t start the task until the night before.” Concrete examples help your GP understand the functional impact.
If you have old school reports, bring them. Evidence of childhood symptoms is part of what an ADHD diagnosis requires. If you’ve had previous mental health treatment, bring those details too. A list of current medications is also helpful.
Screening questionnaires
Your GP may ask you to fill out a standardised screening tool before or during your appointment. The most commonly used ones in Australia are the ASRS-6, a short WHO-developed screener, and the CAARS and DIVA-5 for more detailed assessment.
These inform the clinical picture but don’t diagnose on their own. A high score warrants further assessment. A low score doesn’t rule ADHD out, particularly if inattentive symptoms are the main presentation.
What does it cost?
The GP pathway is substantially more affordable than going directly to a psychiatrist. A GP ADHD assessment is billed at standard consultation rates. With Medicare, your out-of-pocket cost depends on whether your GP bulk bills and how many appointments are needed to reach a diagnosis.
The traditional psychiatrist pathway typically cost between $1,500 and $2,500 out-of-pocket before Medicare rebates. The GP pathway brings that down considerably for straightforward adult presentations.

Common questions
I was a good student. Could I still have ADHD?
Yes. Many people with ADHD, particularly those with high intelligence or supportive environments, compensate well during school. The difficulties often become more apparent later in life when external structure falls away and demands increase.
Does a diagnosis mean I have to take medication?
No. Medication is one option. Psychological strategies, coaching and practical adjustments to how you work and live can make a significant difference too. A diagnosis opens up options rather than committing you to a particular path.
How long does it take?
Under the Queensland GP pathway, a straightforward adult presentation can often be assessed and diagnosed within one to two appointments. The psychiatrist route previously stretched to 6 to 24 months depending on location and demand.
What if my GP doesn’t take it seriously?
You have the right to ask for a referral to a specialist even if your GP is uncertain. ADHD in adults is still under-recognised in some settings. If you feel dismissed, seeking a second opinion is entirely reasonable.
Can my child be assessed too?
Yes. ADHD in children is assessed with input from parents and teachers alongside clinical assessment. Depending on age and complexity, a referral to a paediatrician or child psychiatrist may be part of the process. A GP is still the right starting point.
What if I already have a diagnosis and just need ongoing management?
A GP can handle ongoing prescription management, monitoring and reviews for established ADHD patients. You don’t need to go back through the full assessment pathway.
