Roro ikura Stroke

A stroke happens when you have a bleed or a blood clot blocking the blood supply to part of your brain. This causes damage to brain tissue that might have long-term effects. The effects of a stroke depend on which part of your brain is affected.

Symptoms of a stroke

The main symptoms of a stroke are known as FAST. These are:

  • Face – face drooping on one side.
  • Arm – arm weak on one side. The leg may also be weak.
  • Speech – speech jumbled or slurred.
  • Time – Time is critical. Call 111 for an ambulance.

Other less common symptoms of a stroke include:

  • dizziness, loss of balance or an unexplained fall
  • loss of vision, sudden blurring or decreased vision in one or both eyes
  • headache, usually severe and coming on suddenly
  • difficulty swallowing.
Call 111 immediately if you or someone close to you suddenly develops any stroke symptoms.

Mini strokes (transient ischaemic attack)

Some people develop symptoms similar to a stroke, but fully recover within a few hours. This may be a transient ischaemic attack (TIA), also called a mini stroke.

Diagnosing a stroke

To diagnose a stroke, a doctor will ask about your symptoms and examine you.

If they suspect a stroke, they will arrange further tests, such as:

  • blood tests
  • an ECG (electrocardiogram) to check your heart rhythm
  • a CT or MRI scan of your head.

Treating a stroke

Your treatment depends on the type of stroke you have had, including which part of your brain is affected and what caused the stroke.

Emergency treatment is used to reduce the damage to your brain. If a blood clot has caused your stroke, options include a medicine to dissolve the clot (thrombolysis) and a procedure to remove the blood clot from your brain (clot retrieval).

You may need rehabilitation to help recover from the lasting effects of the stroke. You may have help from a physiotherapist, occupational therapist and speech-language therapist for this.

You will need ongoing treatment with medications to reduce your risk of having a further stroke.

  • After a stroke, making healthy choices can help you recover and reduce your risk of a further stroke and heart attack.

    Changes you can make include:

    • stop smoking, if you smoke
    • keep as active as possible
    • eat and drink well
    • be a healthy weight.
  • You will also need to take preventive medication for the rest of your life. This may include:

    • medication to stop clots forming (antiplatelet medication)
    • medication to control blood pressure
    • statin medication to lower cholesterol
    • blood-thinning medication (anticoagulants) if you have atrial fibrillation.
  • It is common and understandable that you may feel down or anxious after a stroke. It is important to let people know how you are feeling and get help. The Stroke Foundation has advice about depression and anxiety after a stroke.
