Do I Have ADHD?
Signs, Symptoms & How to Get Diagnosed in Australia
Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental conditions in Australia, affecting an estimated 1 in 20 Australians. Yet many people — particularly adults — go undiagnosed for years, struggling with focus, organisation, and impulsivity without understanding why.
What Is ADHD?
ADHD is a condition that affects the brain's ability to regulate attention, impulse control, and activity levels. It is not simply about being energetic or easily distracted — ADHD involves persistent patterns of behaviour that significantly interfere with daily life, relationships, and work or school performance.
There are three main types of ADHD:
Inattentive Type
Difficulty focusing, following instructions, or completing tasks. Often informally called "ADD".
Hyperactive-Impulsive Type
Restlessness, impulsivity, and difficulty staying still or waiting for turns.
Combined Type
A mix of both inattentive and hyperactive-impulsive symptoms — the most common presentation.
Common Signs of ADHD in Adults
ADHD in adults often looks different from how it presents in children. Many adults develop coping strategies that can mask symptoms. Common signs include:
- Difficulty concentrating on tasks, especially repetitive or low-interest work
- Frequently losing items like keys, phones, or important documents
- Chronic disorganisation and trouble managing time
- Impulsively interrupting conversations or making hasty decisions
- Feeling restless, mentally "on the go", or unable to relax
- Struggling to complete long-term projects or follow through on commitments
- Hyperfocusing on enjoyable tasks while neglecting responsibilities
- Mood swings, frustration, and emotional sensitivity
Everyone experiences some of these traits occasionally. ADHD is diagnosed when symptoms are persistent, severe, and impact daily functioning across multiple areas of life.

ADHD Signs in Children
In children, ADHD symptoms may include:
- Difficulty sitting still in class or during quiet activities
- Talking excessively or blurting out answers before questions are finished
- Frequent daydreaming or seeming not to listen when spoken to
- Making careless mistakes and struggling to pay attention to detail
- Difficulty taking turns and playing quietly
- Forgetting to complete homework or chores
What Causes ADHD?
ADHD has a strong genetic component — it tends to run in families. Research shows differences in brain structure and neurotransmitter function (particularly dopamine and norepinephrine) play key roles.
ADHD is not caused by poor parenting, too much screen time, or eating sugar. These misconceptions delay people from seeking help.
How Is ADHD Diagnosed in Australia?
A formal ADHD assessment in Australia typically involves:
- Clinical interview — detailed discussion of symptoms, history, and daily impact
- Rating scales & questionnaires — standardised tools completed by you, and sometimes by partners or teachers
- Collateral information — school reports, work history, and previous assessments
- Differential diagnosis — ruling out other conditions such as anxiety or thyroid issues
What to Do If You Think You Have ADHD
If you recognise several of the signs above and they are affecting your quality of life, the best first step is to speak with a qualified doctor. Early diagnosis and treatment can make a significant difference — helping you understand how your brain works and giving you the tools to thrive.
