What would I know: on brain injury, advocacy and the comfort of consensus

Estimates suggest that between 500 000 and 700 000 Australians live with the effects of Acquired Brain Injury (ABI). The fact that nobody can give an exact number is itself revealing. Despite the enormous scale of the problem, remarkably little coherent strategy exists to address it. That paradox itself should provoke feverish critique of the system, but instead of critical analysis, those within the field often respond with reinforcement. 

A relatively small network of ABI clinicians, researchers, advocates, service providers and highly engaged patients repeatedly amplify one another’s assumptions, priorities and language while remaining insulated from serious external critique. The result is a form of unconscious, inadvertent, incestuous amplification that may actively impairing progress in both acute management and long-term rehabilitation.

The problem begins with the heterogeneity of ABI itself. Acquired brain injury is an event, not a single disease. It includes traumatic brain injury, stroke, hypoxic injury, infection, alcohol related injury, tumours and countless other causes. Patients range from infants injured at birth and young athletes, through to elderly patients with vascular disease. Outcomes range from full recovery to profound disability but unlike cancer or cardiology, ABI lacks a clear biomarker, a single specialty owner, or a unified political constituency. 

Tribes and siloes emerge

Acute care systems reinforce acute care priorities. Neurosurgeons, intensivists and emergency physicians focus upon mortality reduction, decompression, haemodynamic targets, thrombectomy times and discharge survival. These are measurable, dramatic and politically attractive metrics. Entire conferences focus on the technical brilliance of saving a life measured in hours or days, yet the long shadow cast by ABI unfolds over decades. Executive dysfunction, social isolation, carer exhaustion, unemployment, substance misuse and recurrent presentations to hospital are not captured in acute datasets. 

Health systems amplify the rescue narrative, while neglecting reconstruction.

Rehabilitation then creates its own feedback loop. Specialist clinicians, allied health teams, advocacy organisations and lived experience groups operate within a morally protected ecosystem in which criticism risks being interpreted as cruelty. I am not laying any blame for this. ABI survivors are underserved and even abandoned, protection from critique comes at a cost. Weak evidence becomes institutionally entrenched because compassionate intent substitutes for rigorous scrutiny. Small studies with surrogate outcomes gain disproportionate authority and broad statements about “the value of rehabilitation” often obscure the uncomfortable reality that rehabilitation outcomes vary enormously depending on patient selection, intensity, timing, social supports and pre-injury characteristics.

The limitations of lived experience

It is here that the institutional elevation of “lived experience” becomes problematic. The term sounds morally unimpeachable, but it hides a profound selection bias. People like me become valuable precisely because we have not entirely moved on. If I had truly recovered, I would be back at work, socially intact, psychologically settled and no longer requiring counselling, mentors, advocacy groups or reflective writing to reconstruct my identity. I would not be attending conferences speaking about brain injury. I would simply have resumed my life.

In that sense, I am not a straightforward success story. I am functioning, articulate and considerably luckier than many. But my continuing visibility within the ABI world partly reflects continuing impairment. The very people most active within advocacy and “lived experience” ecosystems may therefore represent a skewed subgroup: survivors still searching for coherence, support, identity or meaning after injury.

What does recovery really look like?

Equally troubling is the silence surrounding those who supposedly achieve “successful rehabilitation.” We do not hear from those who return to work, resume relationships and disappear from services. Perhaps that reflects genuine recovery, or perhaps many continue to struggle privately with exhaustion, impulsivity, emotional dysregulation, alcohol misuse, social withdrawal or despair while outwardly performing normality. The elevated rates of suicide, self-harm, addiction, family breakdown and unemployment following ABI suggest that the concept of “successful rehab” may itself contain elements of institutional fiction.

Rehabilitation systems often define success pragmatically and administratively: discharge home, independent transfers, return to employment, reduced support hours. Yet these metrics may bear surprisingly little resemblance to whether somebody feels whole, connected, stable or psychologically safe. A patient can meet every formal rehabilitation goal while simultaneously losing their marriage, identity and sense of future. Systems count functional outputs because existential collapse is difficult to code into a spreadsheet.

Patient communities are vulnerable to similar amplification loops. ABI groups provide validation, belonging and practical advice for individuals frequently failed by mainstream systems. Yet they can also stabilise illness identity and reinforce selective narratives. Stories of catastrophic suffering dominate because those are the patients who remain engaged. Stories of inspirational recovery become overrepresented because society prefers redemption arcs. Both distort reality. The truth is usually slower, lonelier and more ambiguous.

The dangers of a closed ecosystem

ABI consistently struggles for strategic visibility because it lacks a coherent lobby structure. Stroke, dementia, spinal cord injury and autism all possess clearer institutional identities and advocacy narratives. ABI disperses across silos. Policymakers therefore repeatedly rely upon the same small groups of experts, providers and advocates to define the problem. Consensus develops not necessarily because the evidence is strong, but because the ecosystem is closed.

The absence of robust longitudinal datasets worsens the problem dramatically. Australia still lacks sufficiently integrated data linking acute care, rehabilitation exposure, employment outcomes, relationship stability, justice involvement, mental health and long-term healthcare utilisation after ABI. In the absence of data, narrative dominates. Whoever tells the most compelling story shapes strategy.

None of this implies bad faith. Most people working in ABI are intelligent, compassionate and committed. That is precisely why incestuous amplification is dangerous. It rarely feels like corruption. It feels like consensus.

Yet closed systems lose epistemic humility. They stop asking whether prevailing assumptions remain true. ABI desperately needs broader datasets, external critique and uncomfortable honesty about outcomes that remain poor despite decades of advocacy and rehabilitation rhetoric.

ABI rehabilitation risks continuing to reassure itself that we are doing all we can.

I don’t believe that we are.
