Stroke Foundation NZ training on what a stroke is, how to recognise the key signs of stroke and how to give someone the best chance of recovery after a stroke is available through the F.A.S.T. Training and Workplace Toolkit.
What is a stroke?
Stroke refers to a sudden interruption of the blood supply to your brain, which can cause permanent damage. There are different types of stroke, described by the Stroke Foundation NZ as follows:
Ischaemic stroke: This is the most common type of stroke, particularly in older people. An ischaemic stroke occurs when a clot blocks an artery in the brain. The clot usually forms in a small blood vessel inside the brain that has become narrowed through high blood pressure, high cholesterol, diabetes or smoking.
Embolic stroke: This occurs when a blood clot or piece of plaque (cholesterol or calcium deposits) on the wall of an artery breaks loose and travels to the brain. When this happens, the flow of oxygen-rich blood to the brain is blocked and tissue is damaged or dies.
Haemorrhagic stroke: This occurs when an artery in the brain ruptures (bursts) and leaks blood into the brain (cerebral haemorrhage). This break in the blood pipeline means parts of the brain are deprived of blood and a stroke occurs. Blood irritates brain tissue, causing swelling and pressure, which cause further damage and loss of function. Subarachnoid haemorrhage (SAH) is when blood leaks into the surface of the brain. Intracranial haemorrhage (ICH) is when there is bleeding into the brain tissue itself.
Each year about 9,000 people in New Zealand have a stroke. Strokes are more common as you get older, with 76% of strokes occurring in people over the age of 65 years. However, they can occur in younger adults and even children on rare occasions.
About 80% of strokes are preventable, so check with your doctor, nurse or pharmacist as to what your risk is and what you can do to reduce it.
Check your risk with the Stroke Riskometer app developed by the Auckland University of Technology, NZ, 2015.
How is a stroke diagnosed?
To diagnose a stroke, ambulance and medical teams will ask you a series of questions. These will be about your symptoms, when they started, whether you have any other health conditions, etc. They will also use some standard assessment tools to help assess how urgently you need treatment.
If a stroke is suspected, further tests will be done, such as:
blood tests to check your full blood count, electrolytes, renal function tests, fasting lipids, erythrocyte sedimentation rate and/or C-reactive protein and glucose
These tests should be performed as soon as possible after a stroke. In some cases they may need to be performed as an emergency procedure.
What is the treatment for stroke?
The symptoms you have in the first few days after a stroke may not last forever. If your symptoms are going to improve, they usually do so in the first 2 months after you have a stroke. In many cases, if treatment is received early enough, full recovery is possible.
Early treatment is critical
Time is brain – meaning every minute counts and the longer brain cells are without oxygen, the more damage that is done. If treatment is started within a few hours, more brain cells can be saved.
Where possible, stroke patients are now treated within specialist stroke units. In most cases, treatment includes medication, rehabilitation and lifestyle changes.
In the acute phase:
Medicine may be given intravenously to help dissolve blood clots (acute stroke thrombolysis).
Sometimes surgery is needed to treat brain swelling or help reduce further bleeding in cases of haemorrhagic strokes.
In the recovery phase:
Medication is given to lower blood pressure and reduce cholesterol levels.
Depending on the type of stroke and parts of the body affected, a range of rehabilitation support may be needed for weeks to months.
Rehabilitation support can range from speech and language therapy to physical therapy and work retraining.
Lifestyle changes are also needed as above to improve diet and exercise levels, support quitting smoking, managing stress and more.
How can I reduce my risk of stroke?
If you are at higher risk of having a stroke or have had one, talk with your doctor, nurse or pharmacist about what you can do to lower this risk.
If you or someone you know has had a stroke, visit Stroke Foundation of NZ 0800 STROKE (0800 78 76 53). The Stroke Foundation provides a wide range of support, including support groups and educational resources.

"Dianna, a health worker who is Ngāpuhi, experienced a stroke one morning. Fortunately she knew the signs and got help fast. Because of this she has recovered well. Dianna knew she was at risk, given she was a long time smoker and overweight. She has made some changes now, and that day she had her last cigarette."

Like many of us, Rukingi worked 24/7, pushing himself at the expense of his health. Unfortunately, Rukingi’s experience reinforces the horrifying statistics that pin the average age of stroke occurrence in Maori to 56 years old – a conspicuous 15 years earlier than Pakeha.
