A transient ischemic attack (TIA) is a transient stroke that lasts only a few minutes. It occurs when the blood supply to part of the brain is briefly interrupted. TIA symptoms, which usually occur suddenly, are similar to those of stroke but do not last as long. Most symptoms of a TIA disappear within an hour, although they may persist for up to 24 hours. Symptoms can include: numbness or weakness in the face, arm, or leg, especially on one side of the body; confusion or difficulty in talking or understanding speech; trouble seeing in one or both eyes; and difficulty with walking, dizziness, or loss of balance and coordination.
The loss of blood flow to the brain can be caused by:
- Narrowing of a blood vessel
- Blood clot within an artery of the brain
- Blood clot that travels to the brain from somewhere else in the body (for example, the heart)
- Injury to blood vessels
I think you have a right to be concerned about a stroke but there are new drugs and new treatments. Interventional Radiology is making great strides in intervening during a stroke much like cardiac caths for heart attacks.
The time factor is very important for strokes and the need to present to an emergency room promptly may save many people from permanent brain damage.
