GENERAL HISTOLOGY

Detailed explanation-1: -A transient ischemic attack (TIA) is a medical emergency. It is defined as a transient episode of neurologic dysfunction due to focal brain, spinal cord, or retinal ischemia, without acute infarction or tissue injury.

Detailed explanation-2: -A transient ischemic attack, or TIA, is a temporary blockage of blood flow to the brain. The clot usually dissolves on its own or gets dislodged, and the symptoms usually last less than five minutes. While a TIA doesn’t cause permanent damage, it’s a “warning stroke” signaling a possible full-blown stroke ahead.

Detailed explanation-3: -A transient ischemic attack (TIA) is a stroke that lasts only a few minutes. It happens when the blood supply to part of the brain is briefly blocked. Symptoms of a TIA are like other stroke symptoms, but do not last as long. They happen suddenly, and include: Numbness or weakness, especially on one side of the body.
