A Transient Ischemic Attack (TIA), is also known as a “mini-stroke.” It occurs when the blood supply to a part of the brain is briefly interrupted, usually by a blood clot. TIAs are caused by temporary blockages in the blood vessels that supply blood to the brain.
Symptoms of a TIA are similar to those of a stroke, but they usually last for only a few minutes or hours and do not cause permanent damage to the brain. Symptoms of a TIA may include:
Symptoms
- Weakness or numbness on one side of the body
- Trouble speaking or understanding speech
- Vision problems in one or both eyes
- Dizziness or loss of balance
- Difficulty with coordination and fine motor skills
- Confusion or disorientation
Because TIAs are often brief and do not cause permanent damage, they are sometimes referred to as “warning strokes.” TIAs are considered medical emergencies, and prompt evaluation and treatment can reduce the risk of having a major stroke in the future.
Treatment for a TIA typically involves medications to prevent blood clots, such as aspirin or blood thinners, as well as lifestyle changes to manage risk factors for stroke, such as high blood pressure, diabetes, and high cholesterol. Surgery or other procedures may also be used to open up narrowed blood vessels in the neck or head.
It is important to note that although TIAs themselves do not cause long-term damage, they are often an indication that a person is at increased risk of having a major stroke in the future.
