A TEMPORARY distribution in the blood supply to the brain is known as a transient ischaemic attack (TIA) – also known as a “mini stroke”. However, there is nothing minor about this condition.

A mini stroke is indicative of a lack of oxygen reaching the brain, and while the effects might be short-lived – and easily missed – it is an indication that a more brain-damaging stroke is on the way. The NHS pointed out the “sudden” signs of a TIA mini stroke, which can be remembered using the acronym FAST.

n
• 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.

n

• Arms – the person may not be able to lift both arms and keep them there, because of weakness or numbness in one arm.

n

• Speech – their speech may be slurred or garbled, or the person may not be able to talk at all, despite appearing to be awake; they may also have problems understanding what you’re saying to them.

n

• Time – it’s time to call 999 immediately if you notice any of these signs or symptoms.

n

n

Even if these symptoms disappear within minutes, you should still request an ambulance by calling 999.

n

People considered “high-risk” of a stroke include those who have diabetes or high blood pressure.

n

Sometimes, a mini stroke can cause different symptoms that appear over a few seconds.

n

Such symptoms might include:

n
• Complete paralysis of one side of the body

n

• Sudden vision loss, blurred vision or double vision

n

• Vertigo

n

• Being sick

n

• Dizziness

n

• Confusion

n

• Difficulty understanding what others are saying

n

• Problems with balance and co-ordination

n

• Difficulty swallowing (dysphagia).

f you suspect you are having a mini stroke, while awaiting an ambulance, do take an aspirin (if you have one nearby).

n

“You should be referred to see a specialist within 24 hours of the start of your symptoms,” the NHS stated.

n

“A TIA is a warning that you’re at risk of having a full stroke in the near future.”

I think I may have already had a TIA

If you believe you could have had a mini stroke in the past that was not checked out by a medical professional, make an urgent appointment with your doctor.
