If ADHD has come up lately — at a parent-teacher meeting, in a late-night search, or in a quiet "that sounds a lot like me" moment — you are not alone, and you are in a good place to start. ADHD is one of the most talked-about and most misunderstood diagnoses we see. This article walks through what it really is, why it can stay hidden for years, and how a proper assessment can help you or your child move forward with clarity.
What the DSM-5-TR says about ADHD
In Australia, clinicians diagnose ADHD using the DSM-5-TR, the current edition of the Diagnostic and Statistical Manual of Mental Disorders. It describes ADHD (attention-deficit/hyperactivity disorder) as a neurodevelopmental condition: a persistent pattern of inattention, hyperactivity, and impulsivity that gets in the way of everyday functioning or development.
The manual groups the signs into two areas. The first is inattention — losing focus, missing details, struggling to finish tasks, being easily distracted, and forgetting everyday routines. The second is hyperactivity and impulsivity — restlessness, fidgeting, talking a lot, interrupting, and acting before thinking it through.
A few other criteria matter just as much. The signs need to have been present before the age of 12, to show up in more than one setting (such as home and school, or work and relationships), and to genuinely affect daily life. Depending on which signs stand out, a person may be described as having a predominantly inattentive, a predominantly hyperactive-impulsive, or a combined presentation.
The loud kind, and the quiet kind
ADHD does not always look like the stereotype. There are really two presentations people notice, and they can look completely different from the outside.
The outward, hyperactive-impulsive presentation is the one most people picture: the child who cannot sit still, who blurts out answers, who bounces from one thing to the next, and who seems to run on a motor that never turns off. It is visible, and it tends to get picked up early.
Then there is the quieter, more internal presentation. Here the hyperactivity happens on the inside — a mind that races, jumps between thoughts, and never quite switches off, paired with daydreaming, disorganisation, and trouble holding attention. From the outside, this person can look calm, dreamy, or simply "a bit scattered." Because it is so much easier to miss, this internal presentation is often why girls, women, and quieter kids go years without an answer.
You've had ADHD your whole life
ADHD is not something you catch or develop in adulthood. The wiring is there from early childhood. What changes over time is the demand placed on it.
For a long while, many people cope without realising anything is different. They lean on clever workarounds, structure from parents or teachers, natural ability, and sheer effort. It is often only when the demands outgrow those coping strategies — starting high school, moving to university, taking on a bigger job, becoming a parent, or navigating a major life change — that the cracks start to show.
This is why plenty of capable, hardworking adults are diagnosed in their thirties, forties, and beyond. They did not suddenly develop ADHD. Life simply began asking more of them than their usual strategies could quietly absorb.
Why a formal assessment is worth it
A formal ADHD assessment does much more than hand you a label. It gives you an accurate, evidence-based picture of how your brain, or your child's, actually works, which is the foundation for everything that comes next.
The benefits are practical and personal. It replaces unhelpful stories like "lazy," "careless," or "not trying hard enough" with a fair explanation. It can open the door to meaningful support, including school learning plans, exam adjustments, workplace accommodations, and strategies tailored to how the person thinks. A thorough assessment also considers the whole picture, because conditions such as anxiety, low mood, autism, and learning disorders often overlap with ADHD, and untangling them changes what support looks like. And it gives you a clear starting point for any decisions about support, including, if you choose, a conversation about medication with a doctor. If you want to know more about other assessments we offer and pair with ADHD assessments, you can read about them at our assessments page.
It is worth knowing that there is no single ADHD test — no one questionnaire or brain scan can confirm a diagnosis on its own. A quality assessment brings together interviews, a developmental history, questionnaires completed by more than one person, and standardised tools, all interpreted by a qualified psychologist. You can see what our ADHD assessment involves on our ADHD assessments page.
Having ADHD does not mean you have to take medication
If you or your child is diagnosed with ADHD, medication is one option, not an obligation.
Medication helps many people, but it is a personal medical decision, made with a doctor who can weigh the potential benefits and possible side effects for that individual. It is also not the only path. Environmental changes, routines and structure, coaching and practical strategies, therapy for any co-occurring anxiety or low mood, and support at school or work can all make a genuine difference, with or without medication. The right approach is the one that fits the person in front of us. For clarity, psychologists do not prescribe medication; where medication is worth exploring, that conversation happens with a paediatrician, or psychiatrist.

Frequently asked questions
Where do I get an ADHD assessment in Melbourne?
You can be assessed by a qualified psychologist, a paediatrician (a common first point of call for children), or a psychiatrist. At Fielding Feelings, we offer assessments across the lifespan here in Melbourne, with transparent pricing and an upfront quote before you book. Your GP can also help point you toward the right pathway for your situation.
Can I get an ADHD assessment as an adult?
Yes, absolutely. ADHD is lifelong, and adults are assessed and diagnosed every day, many for the first time in their thirties, forties, or later. An adult assessment looks at how the signs show up in your life now and traces them back to childhood, since they need to have been present before the age of 12. We assess adults as well as children and teens.
Does Medicare cover an ADHD assessment?
There is no single Medicare item that covers a full private ADHD assessment as a package, so most of the cost is usually out of pocket. Some individual consultations within the process may attract a partial rebate in certain circumstances — for example, with the right referral pathway — but this varies by situation and changes over time. Because rebates and eligibility are set by the Australian Government, it is worth confirming the current details with Services Australia or your provider. We publish our pricing and give you a full quote upfront, so you will always know the total cost before you commit.
Who can prescribe ADHD medication?
Psychologists cannot prescribe medication, so an assessment with a psychologist gives you a diagnosis and a detailed report, not a script. In Victoria, ADHD medication is prescribed by psychiatrists and paediatricians, and GPs can continue a specialist's prescription with the right approval.
