• Symptoms of Stroke icon plus

  A stroke is either caused by a blood clot in one of your arteries (ischaemic) or when a blood vessel supplying the brain bursts (haemorrhagic). Health conditions such as diabetes, high cholesterol and high blood pressure can also cause strokes. The main symptoms of a stroke are:

  • the face dropping on one side, including the mouth or eye arms
  • weakness of numbness in one arm
  • slurred speech or garbled
  • blurred vision
  • sight loss
  • sudden memory loss or confusion 
  • severe headache

  A stroke is a medical emergency. Call an ambulance (999) if a person has these symptoms.

  Your consultant will carry out urgent imaging and blood tests to determine the cause and extent of the stroke. You'll be give a brain scan immediately — this might be a CT scan or an MRI scan. This determines the cause of the stroke (a blocked artery or a haemorrhage), which part of the brain has been affected and how severe the stroke is. You will also receive physical tests, such as blood tests to determine your blood sugar and cholesterol, and you may also be asked to swallow a small amount of water to ensure the stroke hasn't affected this function.

• Potential treatment options icon plus

  Quick treatment of a stroke can help prevent disability and death. Strokes cause by blood clots (ischaemic) are usually treated with medication such as statins and anti-coagulants. Strokes caused by bleeding on the brain (haemorrhagic) are also treated with medicine and sometimes surgery. Here, blood is removed from the brain and burst blood vessels are repaired. Neuro rehabilitation plays a vital role in stroke recovery, helping a person regain independence if they're left with disability. A team of therapists, including occupational health, speech and language and physiotherapists, will work with you for as long as you need.
