ADHD: A Practical Guide for Australian GPs
Attention Deficit Hyperactivity Disorder (ADHD) is one of the most commonly discussed neurodevelopmental conditions in Australian general practice today.
Yet many patients live for years without recognition.
Some present with:
- chronic anxiety
- repeated depression diagnoses
- poor work performance
- relationship difficulties
- persistent disorganisation
Others simply say:
“I feel like my brain never switches off.”
For many patients, the underlying issue may be undiagnosed ADHD.

What Is ADHD?
ADHD is a neurodevelopmental condition characterised by persistent patterns of:
- inattention
- impulsivity
- hyperactivity
Symptoms usually begin in childhood but often persist into adulthood.
In adults, ADHD may present differently than the classic childhood picture.
Instead of obvious hyperactivity, adults often experience:
- chronic distractibility
- executive dysfunction
- emotional dysregulation
- poor task completion
- difficulty organising daily life
ADHD in Australia
ADHD is increasingly recognised across the lifespan.
According to Australian data summarised by the
Australian Institute of Health and Welfare,
mental health conditions affect a large proportion of Australians across childhood and adulthood.
ADHD is estimated to affect approximately:
- 5–8% of children
- 2–5% of adults
However, many adults remain undiagnosed.
In general practice, ADHD frequently overlaps with other mental health conditions.
Why ADHD Is Often Missed in Adults
Many adults presenting with ADHD were never assessed in childhood.
Instead they may have received diagnoses such as:
- depression
- anxiety
- adjustment disorder
- burnout
- personality disorder
These diagnoses may partly reflect symptoms of untreated ADHD.
For example:
| ADHD symptom | Often labelled as |
|---|---|
| poor concentration | anxiety |
| procrastination | depression |
| emotional dysregulation | mood disorder |
| disorganisation | laziness |
Without exploring developmental history, ADHD may remain hidden.
Common ADHD Presentations in General Practice
Patients may present with concerns such as:
- inability to focus at work
- repeated unfinished projects
- impulsive financial decisions
- difficulty maintaining relationships
- chronic overwhelm
Others present through secondary problems such as:
- anxiety
- depression
- substance use
- chronic stress
The key clinical question is often:
“Has this pattern been present since childhood?”
Initial ADHD Assessment in General Practice
GPs play an important role in identifying possible ADHD.
Initial assessment usually includes:
Developmental History
- childhood school performance
- behavioural concerns
- attention difficulties
- academic struggles
Current Functioning
- work performance
- organisational ability
- emotional regulation
- financial management
Mental Health Review
- anxiety
- depression
- substance use
- trauma history
Screening Tools for ADHD
Several screening tools may assist assessment.
Common examples include:
- ASRS (Adult ADHD Self-Report Scale)
- Conners ADHD rating scales
- DIVA diagnostic interview
These tools help identify symptom patterns but do not replace clinical assessment.
A comprehensive evaluation often requires specialist input.
Diagnosis Pathways in Australia
In Australia, psychiatrists and paediatricians typically confirm ADHD diagnosis.
GPs may:
- Identify possible ADHD
- Conduct initial assessment
- Refer for diagnostic confirmation
- Assist with ongoing management
Some states also require specialist initiation of stimulant medication.
Clinical guidance for mental health care in primary care is available from the
Australian Journal of General Practice - Recognising attention deficit hyperactivity disorder across the lifespan.
Treatment Options for ADHD
Management usually involves a combination of approaches.
Medication
Common medications include:
- methylphenidate
- dexamphetamine
- lisdexamfetamine
- atomoxetine
Medication may significantly improve:
- attention
- impulse control
- emotional regulation
- task completion.
Psychological Support
Psychological strategies may include:
- executive functioning coaching
- cognitive behavioural therapy
- organisational skills training.
These approaches help patients build practical coping systems.
Lifestyle and Environmental Strategies
Many patients benefit from:
- structured routines
- task management systems
- reducing distractions
- regular exercise
- sleep regulation.
Lifestyle structure can be just as important as medication.
ADHD and Comorbidity
ADHD rarely occurs in isolation.
Common coexisting conditions include:
- anxiety disorders
- depression
- substance use disorders
- trauma-related conditions
- learning difficulties.
This complexity explains why some patients spend years in mental health treatment before ADHD is recognised.

The GP’s Role in ADHD Care
General practitioners are often the first clinicians to recognise ADHD patterns.
GP responsibilities may include:
- identifying possible ADHD
- coordinating referrals
- monitoring treatment response
- managing comorbid mental health conditions
- supporting long-term care.
Given the complexity of these consultations, clear documentation becomes important.
Where AI Can Support ADHD Assessments

Clinicians may explore:
- childhood schooling
- family background
- employment history
- emotional patterns
- previous diagnoses.
AI-assisted documentation tools can help by:
- structuring long clinical histories
- organising symptom patterns

Final Thoughts
ADHD is increasingly recognised across the lifespan.
For many adults, diagnosis brings clarity to years of unexplained struggles.
In general practice, the goal is not to rush diagnosis — but to recognise patterns and guide patients toward appropriate assessment and support.
When ADHD is identified and managed properly, the impact can be significant.
Patients often describe it as:
“Finally understanding how my brain works.”
