Chloe AndersonJack Della Maddalena Headlines UFC Perth: What Combat Sports Teach Us About Brain Health
On 2 May 2026, Perth's RAC Arena will host one of Australian sport's most anticipated events of the year. Jack Della Maddalena — "JDM", born and raised in Western Australia — headlines UFC Fight Night against Carlos Prates as the world's #1 ranked welterweight. It is Della Maddalena's first major fight since losing the welterweight title to Islam Makhachev in November 2025. The Perth crowd will be electric.
But beyond the drama of the fight itself, events like UFC Perth bring a quieter question into focus. What does sustained participation in combat sports — whether at elite or recreational level — do to the brain? And what should Australians who box, wrestle, or train in mixed martial arts know about protecting their long-term health?
Head Trauma in Combat Sports: The Science
The brain sits inside a fluid-cushioned skull, but it is not protected against every impact. When a fighter takes a punch, a kick, or a slam, the brain moves inside the skull — bouncing against the inner surface and causing a cascade of biochemical changes at the cellular level. A single significant impact can cause concussion. Repeated subconcussive impacts — blows that don't cause immediate symptoms — accumulate over time.
The cumulative effect of repeated head impacts is now the subject of significant medical and legal attention through research into Chronic Traumatic Encephalopathy (CTE). CTE is a progressive neurodegenerative disease linked to repetitive traumatic brain injury. It has been found post-mortem in the brains of former boxers, American football players, and contact sports athletes across multiple disciplines.
According to Healthdirect Australia, the Australian Government's health information service, concussion symptoms include headache, confusion, dizziness, difficulty concentrating, sensitivity to light and noise, and sleep disturbances. Crucially, concussion symptoms can be delayed — appearing hours or even days after the impact — which means athletes and coaches can underestimate the extent of an injury at the time it occurs.
What Makes MMA Different From Boxing?
Mixed martial arts introduces head trauma risks that differ from boxing in important ways. Fighters face strikes from fists, elbows, knees, and kicks — a wider variety of impact types and angles. Ground-and-pound positions can place a grounded fighter in a particularly vulnerable position, with little room to roll or absorb strikes.
On the other hand, MMA matches are typically shorter than professional boxing bouts, and fights are stopped earlier by referees and ringside doctors when a fighter is in danger. The UFC's medical protocols have evolved significantly in recent years, including mandatory neurological testing, pre-fight medical clearances, and medical suspensions after KO or TKO stoppages.
Della Maddalena's recent title loss to Makhachev was a unanimous decision loss — he was not knocked out or stopped — meaning his return to competition follows a different medical pathway than a fight-ending finish. But even decision losses accumulate cumulative head impact, and professional fighters operate under different return-to-competition parameters than recreational athletes.
Signs That Warrant Medical Attention
For the hundreds of thousands of Australians who train in boxing, MMA, kickboxing, wrestling, or Brazilian jiu-jitsu, the medical landscape is different from elite sport. There are no ringside doctors, no mandatory medicals, and no governing body requiring post-event neurological testing.
Anyone who participates in contact combat sports should know the warning signs that require prompt medical attention:
- Loss of consciousness, even briefly, following a blow to the head
- Persistent headache that does not resolve within 24 hours after training or competition
- Confusion or disorientation following a hard sparring session
- Vision disturbances including double or blurred vision
- Unsteadiness or poor coordination lasting more than a few minutes
- Amnesia — inability to recall events immediately before or after the impact
- Vomiting following a head impact
- Sleep disturbances that emerge in the days following a heavy contact session
Any single severe symptom, or a cluster of milder symptoms that persist for more than 24-48 hours, warrants assessment by a GP or — in the case of significant symptoms — an emergency department visit.
Long-Term Protection: What Recreational Fighters Can Do
Professional fighters like Della Maddalena have access to nutritionists, physiotherapists, sports psychologists, and medical teams. Recreational athletes generally do not. Practical steps for people who train in combat sports include:
Head gear in sparring: Full-contact sparring without protective headgear dramatically increases cumulative head impact. Gyms that require headgear in sparring for non-competitive training provide a meaningful reduction in long-term risk.
Monitoring cumulative load: Elite sports scientists track training load to prevent overtraining. The same principle applies to sparring. Two hard sparring sessions per week is very different from six.
Recovery between impacts: The brain's recovery from even subconcussive impacts takes longer than it may feel subjectively. Training through the recovery period compounds risk.
Post-concussion protocol: After any concussion, returning to contact training requires a stepwise return-to-sport protocol. Graded exercise testing under medical supervision is the gold standard before returning to full-contact activity.
When to See a Specialist
General practitioners can assess and manage most concussion presentations. For fighters with a history of multiple concussions, or for anyone experiencing persistent cognitive symptoms — difficulty concentrating, memory problems, mood changes — referral to a neurologist or sports medicine physician with expertise in brain injury is warranted.
Earlier this year, the medical questions surrounding Jai Opetaia's ongoing boxing career raised similar concerns. The pattern is consistent: Australian boxing and MMA fans cheer on their champions, but the conversations about long-term brain health in combat sports remain too rare outside elite sporting institutions.
Jack Della Maddalena is a remarkable athlete at the peak of his career. His fight on 2 May will be one of the highlights of the Australian sporting calendar. The lesson for every Aussie who trains in combat sports is that elite performance and long-term brain health require the same fundamental attention: respect the risks, know the warning signs, and get proper advice when something doesn't feel right.
