Stroke is rising in under-65s. Know these symptoms immediately.

Dru Arnold is 39. A concreter from the Sunshine Coast, he woke in February 2026 with slurred speech and a severe headache. He decided to sleep it off.

By the time he reached Sunshine Coast University Hospital, doctors discovered he had suffered three strokes within the preceding 24 hours. They also identified evidence of a prior stroke he had sustained two years earlier — which had gone unrecognised at the time.

Seven months on, Arnold has largely recovered. His speech is still affected.

He is direct about what he wishes had been different: “If we knew, I could have been better than I was, we could have got to the hospital a day earlier.”

Most people at 39 are not thinking about stroke. That is the core of the problem.

The trend that matters

Stroke is not a new disease, and it remains predominantly an illness of older adults. In 2024, stroke claimed 9,147 Australian lives, with one person affected every 11 minutes. The Stroke Foundation’s Kelvin Hill has been explicit about a shift that clinicians are tracking: rates among people under 65 are rising. The conditions driving that shift are familiar — obesity, type 2 diabetes, and hypertension are emerging earlier in life than they did a generation ago. When those risk factors arrive in your 30s and 40s instead of your 50s and 60s, the cardiovascular consequences follow on the same trajectory.

Stroke nurse consultant Bailey McNamara, who works at the same hospital that treated Arnold, framed the clinical reality plainly: every minute a stroke goes untreated, an estimated 1.9 million brain cells die without adequate oxygen. The treatments that change outcomes — thrombolysis and mechanical thrombectomy — operate within narrow time windows. Arriving at a stroke unit early enough to receive them is the difference that clinical teams can observe directly. Danika Lloyd, the stroke nurse who cared for Arnold, described him as “very lucky” given the delay.

Younger people, she noted, frequently underestimate their stroke risk — attributing symptoms to a migraine, exhaustion, or something that will pass.

Both-and: prevention and recognition are different problems

The Stroke Foundation estimates that 80 per cent of strokes are preventable through active management of known risk factors: blood pressure, cholesterol, blood glucose, smoking, alcohol, weight, and physical activity. That is a population-level figure, and it reflects the genuine opportunity that exists before a stroke happens.

Prevention and recognition are, however, separate challenges. The prevention side operates over months and years — GP visits, medication, lifestyle adjustment, regular monitoring. The recognition side operates over minutes. Once a stroke is occurring, the prevention conversation is over and the only variable is how fast care begins.

The FAST acronym is the practical tool for recognition: Face drooping, Arm weakness, Speech slurred or difficulty finding words, Time to call 000. Beyond those four, additional symptoms worth acting on immediately include sudden severe headache unlike any you have experienced before, sudden vision changes, sudden difficulty walking or loss of balance, and sudden numbness or weakness — particularly on one side of the body.

Sleeping off any of those symptoms, as Arnold did, is the most common and most costly delay.

2 cents

If you are in your 30s, 40s, or 50s and have untreated high blood pressure, unmanaged type 2 diabetes, or elevated cholesterol you have never had checked: those are the risk factor conversations worth having with your GP. Not because stroke is inevitable, but because those conditions are the modifiable levers, and many Australians carry undetected hypertension — a condition with no symptoms but with meaningful cardiovascular consequences. A standard blood pressure check, fasting lipids, and fasting glucose take one appointment and give your GP enough to work with.

For immediate recognition: if you experience FAST symptoms — or see them in someone else — call 000. State clearly that you suspect a stroke. Note the time symptoms started; that number directly determines which treatments are available. Don’t drive to the emergency department. An ambulance is faster and allows assessment to begin earlier.

Dru Arnold spent a day at home before seeking help. Time is the variable that clinical teams cannot recover for you once it has passed.

Verdict: yes — clinically important and directly actionable.
