Transient Ischaemic Attack
A transient ischaemic attack (TIA) often called a mini-stroke, happens when the brain’s blood supply is interrupted for a very brief time.
The symptoms are very similar to a stroke (such as weakness on one side of the body, loss of sight and slurred speech) but they are temporary - lasting a few minutes or hours, and then disappearing completely within 24 hours.

In a TIA, the affected part of the brain is without oxygen for just a few minutes. A TIA is a sign that part of the brain is not getting enough blood and that there is a risk of a more serious stroke in the future. So, you should not ignore signs of a TIA - get medical help as soon as you can.
