Expanding Access to ADHD Support Across Australia & New Zealand -A Turning Point in Adult ADHD Care

A significant shift is underway in ADHD healthcare across Australia and New Zealand. Governments have now authorised General Practitioners (GPs) to conduct ADHD assessments for adult patients — a move that could substantially expand access to diagnostic and treatment pathways.

For many adults who have long suspected ADHD but faced prolonged waitlists and high specialist costs, this reform represents a potential breakthrough.

What Has Changed?

In both Australia and New Zealand, policy changes now enable appropriately trained GPs to assess and initiate management for adult ADHD in defined circumstances.

Previously, adult ADHD diagnosis was largely restricted to psychiatrists, contributing to long waiting periods — in some regions exceeding 6–12 months (Australian Senate Community Affairs References Committee, 2023).

This reform:

• Broadens the entry point into ADHD care

• Expiates earlier identification

• May reduce specialist bottlenecks

• Encourages shared-care models

Why This Matters

1. ADHD Is Common — and Often Missed in Adults

ADHD affects approximately 5% of children and 2.5–3% of adults globally (American Psychiatric Association, 2013; Faraone et al., 2021). Many adults, particularly women and high-functioning individuals, are diagnosed later in life after years of under-recognition.

Untreated ADHD in adulthood is associated with:

• Increased anxiety and depression

• Occupational instability

• Relationship difficulties

• Higher rates of substance use

• Executive functioning impairments

• Low self-confidence and high self-doubt

Earlier access to assessment can significantly improve life trajectory.

The Role of GPs vs Psychiatrists

While this reform expands access, ADHD remains a complex neurodevelopmental condition requiring careful clinical judgment.

GPs

• May conduct structured assessments

• Can initiate first-line treatment in appropriate cases

• Provide ongoing monitoring

• Coordinate referrals

Psychiatrists

• Manage complex or atypical presentations

• Oversee nuanced medication adjustments

• Assess co-existing psychiatric conditions

• Provide specialist oversight in high-risk cases

It’s been long known that shared-care models have demonstrated improved outcomes in chronic mental health management (Katon et al., 2010). ADHD should be no exception.

The Reality: Early Implementation Challenges

We must remain balanced in our expectations.

• GP capacity is already stretched.

• Specialised ADHD training requires time.

• Not all GPs will opt into ADHD assessment.

• Rural access disparities may persist.

Reform alone does not equal immediate accessibility. Implementation, training, and funding structures will determine success.

What has our experience in BEHAVIOURAL HEALTH taught us:

- Symptom Overlap Leads to Misdiagnosis - Many other psychiatric, medical, and neurodevelopmental conditions can mimic, mask, or exacerbate ADHD-like symptoms.

- Co-existing conditions are the Rule, Not the Exception - Research consistently shows that 50–80% of adults with ADHD have at least one comorbid condition (Faraone et al., 2021).

ADHD is not simply an attention problem. It is a neurodevelopmental condition frequently intertwined with trauma histories, anxiety or mood disorders, learning differences, and personality disorders. Oversimplification risks misdiagnosis, under-treatment, or over-medication.

Common co-occurring conditions:

· Autism spectrum conditions

· Mood disorders

· Learning disorders

· Anxiety disorders

· Substance use disorders

· Personality vulnerabilities

If clinicians focus narrowly on ADHD symptoms without mapping comorbidity:

· Treatment plans become incomplete.

· Medication responses may be misinterpreted.

· Risk factors (e.g., suicidality, trauma) may be missed.

Neurodivergent Interactions Can Exacerbate Presentation

When ADHD co-occurs with autism, learning disorders, or trauma-related adaptations, an individual's presentation may appear:

· More severe

· More emotionally dysregulated

· More treatment-resistant

· More socially complex

For example:

ADHD + autism can amplify executive dysfunction and emotional overwhelm.

ADHD + trauma have overlapping anxiety and impulsivity.

ADHD + anxiety can intensify distractibility and disorganisation.

Treating only ADHD may reduce some of the symptoms — but other underlying drivers remain active.

The Clinical Risk of “Single-Lens” ADHD Assessment

Assessing ADHD without differential diagnosis risks:

• Overdiagnosis

• Underdiagnosis of other conditions

• Fragmented care

• Inappropriate medication

• Poorer long-term outcomes

It may also undermine public trust in care systems.

Our Position

Expanding access to ADHD assessment (e.g., via GPs) is a positive development. We support this reform cautiously and constructively. Expanding assessment pathways is a necessary and overdue step toward reducing inequities in ADHD care. However, accessibility must not come at the expense of diagnostic rigor or thoughtful medication management.

The most effective path forward is collaborative care:

• GPs as accessible first contact

• Psychiatrists as specialist partners

• Psychologists supporting the diagnostic workup and the implementation of strategies

• Patients at the centre of decision-making

If implemented with appropriate safeguards, training, and shared-care protocols, this reform has the potential to reshape adult ADHD care across Australasia.

We recommend accessibility must be matched with:

· Structured diagnostic protocols

· Screening for mood, anxiety, trauma, ASD

· Clear referral pathways for complex cases

· Collaborative care models

ADHD is rarely a standalone condition in adults. Good practice requires a whole-person, lifespan, neurodevelopmental formulation — symptom count alone will inevitably lead to poor care.
