A stroke happens when the blood supply to your brain stops suddenly. It is a medical emergency and if you think you or someone else has had one, act fast.
Is it a stroke? Think FAST and call 111 immediately if you suspect a stroke.
Face: Is it drooping on one side? Arm: Is one arm weak? Speech: Is it mixed-up, slurred or lost? Take action: Call111 immediately.
Key points about stoke
Think FAST to recognise the signs of a stroke: Face, Arm, Speech, Take action.
If you think someone is having a stroke, call 111 immediately.
After a few minutes without oxygen and food from your blood, your brain begins to suffer damage.
If treatment is started within a few hours, permanent damage can be avoided.
What are the symptoms of stroke?
The signs and symptoms of stroke usually come on suddenly. The type of signs experienced will depend on what area of the brain is affected.
Common first signs of stroke include:
Face: sudden drooping, weakness and/or numbness of face
Arm: sudden weakness of the arm (and/or leg)
Speech: difficulty speaking, words jumbled or lost voice.
These FAST symptoms are present in 85% of strokes.
What is a stroke?
Stroke refers to a sudden interruption of the blood supply to your brain, which can cause permanent damage. This interruption can be caused by a blood clot (known as an ischaemic stroke), or by bleeding in your brain (known as a haemorrhagic stroke).
Each year about 9,000 people in New Zealand have a stroke. Strokes are more common as you get older, with 1 in 10 occurring in people aged 75 or older. 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.

Fatigue (excessive tiredness) affects up to 92% of people who have had a stroke. It's normal to get tired after a busy day or not sleeping well the night before. This usually gets better after a good night's rest.
However, fatigue after stroke is an excessive tiredness that will not go away even after a good rest or sleep. You may feel constantly worn out, or have no energy to carry out usual daily activities.
Are you affected by stroke? Are you interested in taking part in a clinical research study in New Zealand on fatigue after stroke? Find out about the FASTER study here.
Causes of fatigue after stroke
It is unclear why you get excessive tiredness after experiencing a stroke. It could be caused by a combination of factors, such as:
brain damage due to stroke
stress after having a stroke
difficulty adjusting to your new life situation.
There are also a number of medical problems that could contribute to excessive tiredness after stroke. These include:
medications that have fatigue as a side effect
See your doctor if you have excessive tiredness after stroke so that they can check if you have any of these medical problems.

This study is conducted by a team of health researchers who work at universities in New Zealand and is funded by the Health Research Council NZ.
What is the purpose of this study?
The purpose of this study is to test a new approach to fatigue management after stroke using cognitive behavioural therapy (CBT). This short-term, goal-oriented treatment uses a practical approach to problem-solving.
What are the criteria for this study?
To be eligible to take part in this study, you need to be:
aged 18 years or older
experiencing fatigue (feeling constantly weary, tired and lacking in energy and strength)
living in Auckland or the Waikato region
able to converse in English
able to provide consent
someone who has had a stroke (confirmed by scan) within the past 3–24 months.
If you have had a previous stroke prior to one in the past 3–24 months, you are still eligible for this study.
If you would like to take part, a researcher will ask you some questions over the phone to check if you may be eligible for this study.
What will happen in this study?
If you are eligible and would like to take part, a time will be arranged for a member of the study team to meet with you in person. The purpose of this meeting is to ask you some questions and to ask you to perform a physical task, if possible. Everyone on the study team has been trained for this project.
When a researcher comes to visit you, you will have the opportunity to ask any questions you might have about the study. If you are happy to take part, the researcher will check a few more details with you to make sure that you are fully eligible to participate. This initial visit should take about 1 hour. If you take part, a member of the study team would like to visit you on 3 occasions over the next 3 months.
If you like, you are welcome to have a support person with you during each visit. After the first visit, you will be randomly allocated to receive one of two group education programmes.
If you are assigned to Programme 1, you will be asked to attend one group education session each week for a total of 6 weeks. Each group session will take between 1–1.5 hours.
If you are assigned to programme 2, you will be asked to attend a single, one-off support group education session. This group session will take approximately 1.5 hours.
A member of the study team will come to visit you at 6 weeks and 3 months after the start of either programme. They will ask you similar questions at visit and will ask you to perform a physical task, if possible.
