Mini strokes are also known as a TIA – a transient ischaemic attack.
Like strokes, a TIA is caused by a blood clot blocking an artery leading to the brain.
The symptoms are the same as those of a stroke, and usually begin suddenly. The difference is the symptoms only last for a few minutes or hours as the blockage is temporary.
A TIA is a warning that you may be at risk of having a full stroke in the near future – but how can you prevent one happening in the first place?
There are four ways according to the NHS.
The best way to help prevent a TIA is to eat a healthy diet, exercise regularly, and avoid smoking and drinking too much alcohol.
The health body states there are four main symptoms of strokes and TIAs to watch out for, which can be remembered with the word FAST.
F stands for face – the face may have dropped on one side, the person may not be able to smile, or their mouth or eye may have drooped.
A is for arms – the person with suspected stroke may not be able to lift both arms and keep them there, because of arm weakness or numbness in one arm.
S is for speech – their speech ay be slurred or garbled, or the person may not be able to talk at all, despite appearing to be awake.
T is for time – it’s time to dial 999 immediately if you notice any of these signs or symptoms.
Other signs and symptoms of strokes may include: complete paralysis of one side of the body, sudden loss or blurring of vision, dizziness, confusion, difficulty understanding what others are saying, problems with balance and co-ordination, and difficulty swallowing.
It can be difficult to know in the early stages of a TIA whether you’re having a mini stroke or a full stroke, but if you or someone experience any of the symptoms you should phone 999 immediately.
The NHS advises: “A TIA is a warning that you’re at risk of having full stroke in the near future. An assessment can help doctors determine the best way to reduce the chances of this happening.
“If you think you’ve had a TIA previously, but the symptoms have since passed and you didn’t seek medical advice at the time, make an urgent appointment with your GP. They can refer you for a hospital assessment, if appropriate.”
If you want to reduce the risk of a stroke happening in the first place, the Stroke Association suggests being more physically active.
Physical inactivity can increase your risk of stroke, heart disease, becoming overweight, developing high blood pressure, high blood cholesterol and diabetes, heart disease and stroke.
It recommends going on a brisk walk, taking the stairs, and doing whatever you can to make your life more active.
But whatever physical activity you do, the charity recommends doing it for a certain amount of time.
It states on its website: “Try to get a total of at least 30 minutes of activity on most or all days.”
Eating a healthy, balanced diet, can also help prevent a stroke happening.
If you’ve had a stroke, you should talk with a registered dietician to learn how to plan and prepare meals and snacks – and one thing in particular the National Stroke Association recommends is not to miss breakfast.
It states: “You will feel healthier, be less hungry, and snack less.”
Heavy drinking raises your risk of stroke, but a small amount each day can have a protective effect.
