Short web summary: Recent data show ADHD diagnoses and medication use rising sharply in Western Australia, with suburbs like Fremantle emerging as national hotspots. This post explains why the real story is an epidemic of mismatch and inequity, drawing on evolutionary science and local WA data to argue that modern environments are out of sync with how our brains are wired.
This article unpacks the complex landscape of ADHD in Western Australia, moving beyond the sensationalist "epidemic" headlines to explore the data, the history, and the evolutionary science behind the surge. You will learn why certain postcodes are hotspots, how our "disruptible" brains are actually an evolutionary legacy, and why the real challenge isn't just a brain disorder, but a chronic mismatch between our wiring and our modern environment.
The Data: A Tale of Two West Australias
To understand what’s happening "under the hood" of WA’s mental health system, we have to look at the numbers. Recent PBS (Pharmaceutical Benefits Scheme) data commissioned by the ABC offers a clear, if startling, diagnostic map.
As of 2024–25, approximately 2.36% of Australian adults aged 20–65 received at least one prescription for ADHD medication. On the surface, this aligns with global prevalence estimates (typically 2–3%), suggesting that as a nation, we aren't necessarily "over-medicating." However, the data reveals a massive geographical skew.
The "Hotspot" Phenomenon
Thirteen of the top 20 ADHD prescribing "hotspots" for adults in the entire country are located right here in Western Australia. Fremantle, in particular, stands out as a national leader in prescribing rates.
Conversely, in many low-income suburbs across other states, prescribing rates are so low that experts estimate up to 90% of adults with ADHD remain undiagnosed and untreated. We aren't seeing a uniform rise in ADHD; we are seeing a "postcode lottery" where access to diagnosis is tied to socioeconomic status and local awareness.
| Metric | National Average (Adults) | WA Hotspot Trend |
|---|---|---|
| Prescription Rate (2024-25) | 2.36% | Significantly Higher |
| 10-Year Medication Surge | ~300% Increase | Accelerated in WA |
| Untreated Rate (Low-SES) | High (est. 90%) | High disparity |
Why WA is "Ahead of the Curve"
Western Australia has a unique clinical history with ADHD. For over a decade, WA Health figures have identified ADHD as the state's most common developmental disorder in children. We have historically stayed "ahead of the curve" nationally, often being the first to adopt new diagnostic trends or policy shifts.
The WA Government is currently leaning into this role with "game-changing" reforms. By the end of 2026, a cohort of specialist GPs will be trained to diagnose ADHD from age 10 and prescribe stimulants: a move designed to break the bottleneck of private psychiatry waitlists. While this improves access, it also operates in a landscape where certain communities are already highly medicalised, while others remain invisible.
The "Evolved to be Disrupted" Perspective
At Keystone Therapy, we prefer to look at the "mechanics" of the brain through an evolutionary lens. Most public debate is stuck in a binary: Is it a fad or is it finally being recognised? Neither of these tells the whole story.
We propose an "Evolved to be Disrupted" model. This perspective, rooted in evolutionary psychiatry, suggests that the traits we now label as "ADHD symptoms" were once survival advantages.
The Hunter-Gatherer Legacy
Evolutionary research suggests that traits like fast scanning (distractibility), novelty seeking (impulsivity), and rapid switching of attention were incredibly useful in unpredictable, physically active environments.
- Fast Scanning: Allowed for the quick detection of threats or food sources.
- Novelty Seeking: Drove exploration and the discovery of new resources.
- Hyper-focus: Provided the intense drive needed for successful hunting or tool-making.
These traits are highly heritable and have persisted for thousands of generations. They aren't "broken" parts; they are "legacy software" that worked perfectly for most of human history.
Modern Life: The Great Environmental Mismatch
If these brains aren't "broken," why are so many Western Australians struggling? The answer lies in Environmental Mismatch. Our attentional systems evolved for a world of physical movement and tangible threats, yet we now live in an environment designed to hijack that very wiring.
Modern WA life, particularly in knowledge-work hubs like Fremantle or the corporate sectors of Perth, demands:
- Sustained Linear Focus: Sitting at a desk for 8-9 hours focusing on a single screen.
- Digital Fragmentation: Navigating a constant stream of notifications, emails, and pings specifically engineered to grab our attention.
- Sedentary Load: A lack of physical outlet for brains that are wired for movement.
- High Mental Load: Juggling the financial pressures and work-life demands of a modern "24/7" economy.
In this context, a "disruptible" brain isn't failing because of a defect; it is failing because it is being asked to operate in a habitat that is fundamentally incompatible with its wiring. We are seeing an epidemic of mismatch, not an epidemic of disease.
Beyond the Checklist: The Keystone Approach
At Keystone Therapy, we don't believe a simple checklist is enough to capture the complexity of a human life. Whether you are dealing with stress and relationships or seeking to understand your interpersonal neurobiology, we look at the whole system.
We move beyond the "over vs. under-diagnosed" debate by asking three critical clinical questions:
- Wiring: How is this specific person’s brain naturally oriented?
- Environment: Where is the friction between their wiring and their daily life?
- Intervention: What combination of behavioural activation, environmental adjustment, and medical support will actually improve their wellbeing?
The ARCHR²™ Framework
To provide holistic support, we utilize the ARCHR²™ framework, which balances clinical expertise with practical application. We don't just treat the "check engine light" (the symptoms); we look at the entire engine.
For many, this includes addressing the pillars of health that often collapse under the weight of ADHD-like struggles, such as sleep regulation or the development of social rhythms.
Changing the Public Narrative in WA
The "epidemic" in Western Australia is a symptom of a state that is both structurally ready to diagnose and environmentally prone to disruption. To move forward, we need a calmer, more nuanced conversation.
- Acknowledge the Struggle: Diagnosis can be a profound relief for those who have spent a lifetime feeling like a "faulty" version of a normal person.
- Address the Inequity: We must ensure that diagnostic pathways aren't just reserved for the affluent, but are accessible to everyone who is struggling, regardless of their postcode.
- Question the Environment: We need to be honest about how digital technologies and modern workplace cultures are exacerbating these difficulties.
If you feel like your brain is "evolved to be disrupted," you aren't alone, and you aren't broken. You are likely just a high-performance engine trying to drive on a road that wasn't built for you.
In Summary
Western Australia’s ADHD surge is a complex mix of historical clinical patterns, a shift in adult awareness, and a modern lifestyle that is increasingly hostile to the "disruptible" brain. At Keystone Therapy, we work to bridge that gap. By understanding your unique neuro-mechanical makeup, we can help you find a way to thrive in a world that wasn't necessarily designed for your wiring.

Next Steps:
- Audit your environment: Identify three "friction points" where your current workspace hijacks your attention.
- Regulate your rhythm: Look into how social rhythm therapy can help stabilize a disruptible system.
- Seek expert guidance: If you suspect a significant mismatch, consult a professional who looks beyond the checklist.
