Every year approximately 150,000 people in the United Kingdom have a stroke. Most of these people are aged over 65 years old, but strokes can happen at any age, even to children and babies.
What is a stroke?
A stroke occurs when an area of the brain is deprived of its blood supply, causing brain tissue to die. This is usually the result of a clot or burst blood vessel. The signs of a stroke are facial weakness, arm or leg weakness, speech problems and loss to half of the visual field.
These signs may only last for a few hours, which is called a Transient Ischaemic Attack (TIA), but they must not be ignored. Early treatment saves lives and increases the chances of making a better recovery.
There are two main types of stroke:
- Ischaemic stroke – This is the most common type of stroke, which occurs when the artery is blocked by a blood clot.
- Haemorrhagic stroke – This is when a blood vessel ruptures, causing bleeding or a haemorrhage.
Signs of a stroke
The first signs that someone has had a stroke are very sudden. Symptoms include:
- numbness, weakness or paralysis on one side of the body (signs of this may be a drooping arm, leg or lower eyelid, or a dribbling mouth);
- slurred speech or difficulty finding words or understanding speech;
- sudden blurred vision or loss of sight;
- a severe headache.
A stroke is a medical emergency. If you see the signs of a stroke, you need to act FAST and call 999.
These simple checks can help you recognise whether someone has had a stroke or a mini-stroke (TIA):
- F – Facial weakness: Can the person smile? Has their mouth or eye drooped?
- A – Arm weakness: Can the person raise both arms?
- S – Speech problems: Can the person speak clearly and understand what you say?
- T – Time it is time to dial 999 immediately if you see any of these symptoms.
If you see any of these signs, dial 999 immediately. For further information and advice, read the NHS leaflet When stroke strikes, act F.A.S.T..
Ways to help prevent a stroke
Some people are more likely than others to suffer a stroke, but there are several ways to reduce your chances of having one:
- Diet – Too much salt and saturated fats increases the risk of having a stroke. Saturated fats are found in foods such as red meat, cheese and butter. Eating fruit, vegetables, wholegrain cereals, fibre and unsaturated fats can help to significantly lower the risk of stroke. Unsaturated fats are found in foods such as nuts, seeds and oily fish.
- Exercise – Regular exercise helps to reduce the risk of stroke by enhancing circulation, lowering blood pressure, lowering cholesterol levels and keeping body weight down.
- Lifestyle – Other ways to help to reduce your risk of stroke are to stop smoking, stick to safe alcohol limits and watch your weight.
High blood pressure, or hypertension, is the single biggest risk factor for stroke. It contributes to the hardening of the arteries, increasing the risk of them getting blocked; and it puts a strain on the blood vessel walls, increasing the risk of a blood vessel bursting and bleeding into the brain. Both of these are causes of stroke. See our section on High blood pressure (hypertension) to find out more.
Possible effects of a stroke
Aphasia (sometimes called dysphasia) is a disorder caused by damage to the areas of the brain that control language. It is usually caused by a stroke or head injury, and leads to communication problems such as difficulty with talking, understanding, writing or using numbers.
Even everyday tasks can become impossible, such as making telephone calls, shopping, or having a conversation. A common misconception is that the person with aphasia is losing their intelligence, which can also be very distressing and frustrating, for them and their family. There are around 250,000 people with aphasia in the UK, and many of them are under the age of 65 years old.
NETA (North East Trust for Aphasia) is a registered charity set up by people with aphasia and their families. They can provide information and support and also fund ‘Comm-Unity’, an Aphasia Support Centre. The support centre can provide the following services:
- Communication groups
- Family support groups
- Training courses (e.g computers, photography)
- Speech and language therapy
Difficulty in making decisions
If you have had a stroke you may find it difficult to make decisions, and may want to plan ahead in case you are unable to make important decisions for yourself in the future. If you care for someone who has had a stroke, this could also be an issue that causes concern. For more information, visit our section on Making decisions (Mental Capacity).
Local Help and Support
