Transient Ischaemic Attacks


What is Transient Ischaemic Attack?

Transient Ischaemic Attacks are transient neurological dysfunction. It involves the appearance of a sudden focal neurologic deficit that clears completely in less than 24 hours.

The brain has its own blood supply, which gets interrupted for a short while. The cause lies in the heart or blood vessels elsewhere, and TIAs are warning signs of an impending stroke unless something is done about the cause. Arterial narrowing or occlusion and inadequate collateral circulation produce transient focal ischaemia (low flow) to a particular area of the brain. A transient short-lived episode of the weakness of one half of the face, an arm, leg and foot results. Speech difficulties may arise.

Repetitive episodes of dizziness and double vision may also occur.

The patient must compulsorily be seen by a physician to assess and commence necessary treatment.
