Overview
A transient ischaemic attack (TIA) or "mini stroke" is caused by a temporary disruption in the blood supply to part of the brain. The disruption in blood supply results in a lack of oxygen to the brain.
Symptoms
- weakness, numbness or paralysis in the face, arm or leg
- slurred or garbled speech or difficulty understanding others
- blindness in one or both eyes or double vision
- vertigo or loss of balance or coordination
Causes
- a tia has the same origins as that of an ischemic stroke, the most common type of stroke. in an ischemic stroke, a clot blocks the blood supply to part of the brain. in a tia, unlike a stroke, the blockage is brief
Risk factors
- family history.
- age. your risk increases as you get older, especially after age 55.
- sex. men have a slightly higher risk of a tia and a stroke.
Diagnosis
- physical exam and tests.
- carotid ultrasonography.
- computerized tomography (ct) or computerized tomography angiography (cta)
