If you've ever suffered a sudden onset of dizziness, or the vision in one eye is quickly distorted or blurred, you may have experienced what's known as a
transient ischemic attack (TIA), or ministroke. And there are other indicators that might suggest the onset of an event of this kind. A TIA is a temporary blockage of blood flow to part of the brain, the spinal cord, or the thin layer of tissue at the back of the eye known as the retina. A TIA doesn't cause permanent damage to the brain, but it does serve as a warning that you may be predisposed to a more serious stroke.
