Understanding Stroke
A stroke, sometimes called a 'brain attack', occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die within minutes. This can lead to long-lasting brain damage, disability, or even death. Strokes are a leading cause of disability in Australia, but prompt recognition and treatment can significantly improve outcomes. Understanding the different types of stroke and their causes is the first step in prevention and effective management.
There are two main types of stroke:
Ischaemic Stroke: This is the most common type of stroke, accounting for around 85% of all cases. It occurs when a blood clot blocks a blood vessel in the brain. These clots can form in the brain or travel from other parts of the body, such as the heart.
Haemorrhagic Stroke: This type of stroke happens when a blood vessel in the brain ruptures and bleeds into the surrounding brain tissue. Haemorrhagic strokes are often more severe than ischaemic strokes.
Several factors can increase your risk of stroke, including:
High blood pressure
High cholesterol
Smoking
Diabetes
Heart disease
Obesity
Family history of stroke
Recognising the signs of a stroke and acting quickly is critical. The faster someone receives treatment, the less damage to the brain and the better their chances of recovery. That's where the FAST assessment comes in.
The FAST Assessment: Face, Arms, Speech, Time
The FAST assessment is a simple and effective way to remember the key signs of a stroke. It stands for Face, Arms, Speech, and Time. If you suspect someone is having a stroke, use this assessment to quickly evaluate their condition.
Face
Ask the person to smile. Does one side of their face droop? Facial drooping or weakness is a common sign of stroke. The smile may appear uneven or lopsided.
Arms
Ask the person to raise both arms. Does one arm drift downwards? Weakness or numbness in one arm is another common sign. They may struggle to lift one arm as high as the other.
Speech
Ask the person to repeat a simple sentence, such as "The sky is blue." Is their speech slurred or strange? They may have difficulty understanding you or finding the right words. Their speech may sound garbled or nonsensical.
Time
If you observe any of these signs, even if they are subtle or temporary, it's time to call emergency services (000 in Australia) immediately. Note the time when the symptoms started. This information is crucial for medical professionals as certain treatments are most effective within a specific time window after the onset of stroke symptoms. Time is brain – the faster treatment is administered, the better the outcome. The emergency responders can provide immediate assistance and transport the person to the nearest appropriate hospital.

It's important to remember that not everyone experiences all of these symptoms, and some people may have other symptoms such as sudden vision loss, severe headache, dizziness, or loss of balance. If you suspect someone is having a stroke, even if they only have one symptom, err on the side of caution and call for help.
What to Do While Waiting for Help
While waiting for emergency services to arrive, take the following steps:
Keep the person calm and comfortable: Reassure them that help is on the way. Try to keep them as relaxed as possible.
Loosen any tight clothing: This can help improve blood flow.
Position the person safely: If they are conscious, help them lie down on their side with their head slightly elevated. This can help prevent choking if they vomit. If they are unconscious, place them in the recovery position.
Monitor their breathing and level of consciousness: Check their breathing regularly. If they stop breathing, be prepared to perform CPR if you are trained to do so. Note any changes in their level of consciousness and report these to the paramedics.
Do not give them anything to eat or drink: This is because they may have difficulty swallowing, which could lead to choking.
Gather information: If possible, gather information about the person's medical history, medications, and allergies. This information will be helpful for the medical team.
Stay with the person until help arrives: Provide reassurance and monitor their condition. If you have any first aid training, use your skills to assist them. Firstaiders offers a range of courses to equip you with these life-saving skills.
Preventing Stroke
While some risk factors for stroke, such as age and family history, are beyond our control, there are many lifestyle changes we can make to reduce our risk. Prevention is always better than cure, and adopting a healthy lifestyle can significantly lower your chances of having a stroke.
Here are some key steps you can take to prevent stroke:
Control high blood pressure: High blood pressure is a major risk factor for stroke. Monitor your blood pressure regularly and work with your doctor to keep it under control through lifestyle changes and medication if necessary.
Lower cholesterol: High cholesterol can lead to the build-up of plaque in your arteries, increasing the risk of blood clots. Eat a healthy diet low in saturated and trans fats, and consider medication if recommended by your doctor.
Quit smoking: Smoking damages blood vessels and increases the risk of blood clots. Quitting smoking is one of the best things you can do for your health.
Manage diabetes: Diabetes can damage blood vessels and increase the risk of stroke. Control your blood sugar levels through diet, exercise, and medication if necessary.
Maintain a healthy weight: Obesity increases the risk of high blood pressure, high cholesterol, and diabetes, all of which are risk factors for stroke. Aim for a healthy weight through diet and exercise.
Eat a healthy diet: A diet rich in fruits, vegetables, and whole grains can help lower your risk of stroke. Limit your intake of saturated and trans fats, cholesterol, and sodium.
Exercise regularly: Regular physical activity can help lower your blood pressure, cholesterol, and weight, all of which can reduce your risk of stroke. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
Limit alcohol consumption: Excessive alcohol consumption can increase your risk of stroke. If you drink alcohol, do so in moderation.
Manage stress: Chronic stress can contribute to high blood pressure and other risk factors for stroke. Find healthy ways to manage stress, such as exercise, yoga, or meditation. What we offer includes information on health and wellbeing programmes.
Post-Stroke Care
Recovery from a stroke is a long and challenging process, but with the right support and rehabilitation, many people can regain lost function and improve their quality of life. Post-stroke care focuses on helping individuals regain independence and participate in meaningful activities.
Key aspects of post-stroke care include:
Rehabilitation: This may include physical therapy, occupational therapy, and speech therapy. Physical therapy helps improve movement, balance, and coordination. Occupational therapy helps with daily living skills, such as dressing, bathing, and eating. Speech therapy helps with communication and swallowing.
Medication: Medications may be prescribed to prevent future strokes, manage blood pressure, cholesterol, and diabetes, and treat other medical conditions.
Emotional support: Stroke survivors and their families often experience emotional challenges, such as depression, anxiety, and frustration. Counselling and support groups can provide valuable emotional support.
Lifestyle changes: Continuing to follow a healthy lifestyle, including eating a healthy diet, exercising regularly, and quitting smoking, is crucial for preventing future strokes and improving overall health.
Assistive devices: Assistive devices, such as walkers, canes, and wheelchairs, can help stroke survivors regain independence and mobility.
- Home modifications: Modifying the home environment to make it more accessible can help stroke survivors live more independently. This may include installing grab bars in the bathroom, widening doorways, and adding ramps.
Stroke recovery is a marathon, not a sprint. It requires patience, perseverance, and a strong support system. With the right care and rehabilitation, stroke survivors can achieve significant improvements in their function and quality of life.
