Stroke is the third most common cause of death in Australia
The most common type of stroke is an ischaemic stroke, caused by a blood clot blocking an artery and interrupting blood flow to the brain. If the blood supply is blocked for more than a few minutes, brain tissue begins to die. If the blockage is not cleared within a few hours, the affected area of the brain may die and leave a scar, known as brain infarction. Ischaemic strokes occur more than five times as often as haemorrhagic strokes, which are caused by a ruptured blood vessel within or surrounding the brain.
The signs of a stroke include weakness or lack of movement in the legs and/or arms, with specific effects depending on the extent of brain damage and where in the brain the stroke occurred. While the symptoms and severity vary, people with mild symptoms should still seek urgent attention as they may be experiencing a "mini stroke", which is a warning sign of a more severe stroke.
The annual cost of stroke to the Australian economy is $9 billion, including healthcare costs, lost productivity, and the provision of informal care. With the Australian population increasing and ageing, the number of strokes is expected to rise, and significant investment is needed to reduce the burden on the country's health system and economy.

About 55,000 Australians have strokes annually
Stroke is a common and serious medical condition in Australia. About 55,000 Australians have strokes annually, with 73% of these being first-time strokes. This equates to more than 100 strokes every day. The Stroke Foundation's Economic Impact of Stroke Report, released in 2023, found that 45,785 Australians experienced a stroke that year, or one stroke every 11 minutes. The report also predicted that by 2050, the number of strokes per year will increase to 72,000.
Stroke is the third most common cause of death in Australia, with around 10,600 Australians dying from stroke each year. In 2022, stroke was the underlying cause of 8,400 deaths, or 4.4% of all deaths and 19% of CVD deaths. The rate of stroke deaths was highest among First Nations females, at 43.8 per 100,000 population, and First Nation males, at 384 per 100,000.
Stroke is also a leading cause of disability in Australia. Of the 475,000 stroke survivors alive today, around half suffer from a disability affecting their daily life. 35% remain permanently disabled at one year after their stroke, with 10% requiring care in a nursing home or other long-term facility. The specific abilities that are lost or affected by a stroke depend on the extent of the brain damage and the area of the brain affected. The right hemisphere of the brain, for example, controls the movement of the left side of the body, so a stroke in this area often causes paralysis on the left side.
The rates of stroke-related deaths have dropped significantly over the last 30 years, but stroke continues to have a significant impact on the Australian health system and economy. The costs associated with stroke in 2023 were over $15.7 billion, including $5.5 billion in healthcare costs and $6.3 billion in lost productivity.
The risk factors for stroke include tobacco smoking, high blood pressure, high cholesterol, abnormal blood lipids, TIA, atrial fibrillation, diabetes, and other heart diseases. Ischaemic strokes, which are caused by blood clots, are the most common type of stroke, occurring more than five times as often as haemorrhagic strokes, which are caused by ruptured blood vessels.

In 2021-22, the rate of stroke hospitalisations was highest among First Nation males
Strokes are a significant health concern in Australia, impacting thousands of lives each year. According to the Australian Institute of Health and Welfare, an estimated 387,000 Australians aged 15 and over (1.6% of the population) had experienced a stroke at some point in their lives as of 2018. This figure underscores the prevalence of strokes in the country.
In recent years, stroke-related data has revealed concerning trends. In 2023, it was reported that 45,785 Australians experienced a stroke, translating to one stroke every 11 minutes. This data indicates an increasing trend, with projections estimating that the number of strokes per year will surge to 72,000 by 2050. The economic impact of strokes in Australia is also substantial, with costs exceeding $15.7 billion over a lifetime and $9 billion annually for the Australian economy.
While strokes affect people from all demographics, certain populations are at higher risk. In 2021-22, the rate of stroke hospitalisations was highest among First Nation males, with a rate of 384 per 100,000. This is significantly higher than the rate for the general population. Additionally, between 2020 and 2022, the rate of stroke deaths was highest among First Nations females, with 43.8 per 100,000 population. These statistics highlight the disproportionate impact of strokes on Indigenous Australians.
The high rate of stroke hospitalisations among First Nation males warrants further investigation and targeted interventions. Cultural sensitivity and tailored health strategies are crucial to effectively addressing this issue. Additionally, considering the overall high prevalence of strokes in Australia, continued public education on stroke prevention, risk factors, and early warning signs is essential.
Addressing the modifiable risk factors for strokes is paramount. These risk factors include tobacco smoking, high blood pressure, abnormal blood lipids, transient ischaemic attack (TIA), atrial fibrillation, diabetes, and other heart diseases. By proactively tackling these risk factors and enhancing stroke prevention strategies, Australia can make significant strides in reducing the human and economic toll of strokes on its population.

Stroke survivors often suffer from disabilities affecting their daily life
In Australia, about 55,000 to 56,000 people have strokes annually, with around 10,600 dying from it each year. In 2018, an estimated 387,000 Australians aged 15 and over (1.6% of the population) had experienced a stroke at some point in their lives. It is the third most common cause of death in Australia and a leading cause of disability. There are around 475,000 stroke survivors in Australia, and of these, around half suffer from a disability that affects their daily life.
The specific abilities that will be lost or affected by a stroke depend on the extent of the brain damage and where in the brain the stroke occurred. The right hemisphere of the brain, for example, controls the movement of the left side of the body, so a stroke in this area often causes paralysis on the left side. Globally, 60% of stroke patients develop permanent disabilities and experience limitations in mobility, vision, speech, and swallowing function.
Post-stroke survivors frequently experience varying degrees of impairment, necessitating emergency hospital treatment and prolonged home care. It can lower the quality of life, leading to social isolation and making it harder to function independently. Stroke survivors often experience post-stroke fatigue, with survivors feeling permanently tired or low on energy. For some, the fatigue is so severe that it has a significant debilitating effect on their daily lives. The affected side of the body can also suffer changes in how it senses temperature, pain, or textures. It is common for survivors to experience the inability to feel the position of their limbs, leading to actions such as hanging onto a railing while walking and then "forgetting" to let go.
Rehabilitation is crucial for stroke survivors, and patients with high levels of drive were more likely to comprehend rehabilitation. Rehabilitation nurses can help patients relearn the abilities required to perform fundamental daily activities, as well as provide information on basic medical procedures such as taking medications as prescribed, taking care of the skin, dealing with bladder and bowel problems, and getting out of bed and into a wheelchair.

Stroke risk factors include tobacco smoking, high blood pressure, and diabetes
In 2018, around 1.6% of Australians over the age of 15 (or 387,000 people) had experienced a stroke at some point in their lives. In 2022, stroke was the underlying cause of death for 8,400 people in Australia, with an average of 23 stroke-related deaths per day. The rate of stroke deaths was highest among First Nations females.
Strokes are often associated with several risk factors, including tobacco smoking, high blood pressure, and diabetes. Firstly, tobacco smoking is a well-known risk factor for strokes. The risk of having a stroke increases with the amount of smoking, and current smokers have a two- to fourfold higher risk of stroke compared to non-smokers. Tobacco smoke contains over 4000 chemicals, including heavy metals and other toxins, which promote the development of free radicals, leading to vascular endothelial dysfunction and inflammation. This process ultimately contributes to the development and acceleration of atherosclerosis, which is a common precursor to strokes.
High blood pressure, or hypertension, is another significant risk factor for strokes. Hypertension can be managed and controlled through lifestyle changes, such as adopting a healthy diet with reduced salt intake, engaging in regular physical activity, maintaining a healthy weight, managing stress, and limiting alcohol consumption. By working with a healthcare professional, individuals can effectively monitor and maintain their blood pressure within a healthy range.
Additionally, diabetes is closely linked to an increased risk of stroke. People with diabetes have twice the likelihood of experiencing a stroke compared to those without the condition. This association is due to the body's inability to regulate blood glucose effectively, leading to elevated glucose levels in the blood. Over time, high blood glucose can increase fatty deposits or clots in blood vessels, which may eventually result in a stroke. Type 1 diabetes occurs when the pancreas does not produce insulin, while in Type 2 diabetes, the pancreas produces insufficient insulin or the body's cells do not utilize insulin properly. Regular medical check-ups and lifestyle changes, such as maintaining a healthy weight and fibre intake, can help manage diabetes and reduce the risk of stroke.
