Step-by-step explanation:
The medical abbreviation TIA stands for Transient Ischemic Attack. It is a temporary loss of neurological function caused by a brief interruption in blood flow. Although similar to a stroke, a TIA does not last as long. The diagnostic definition of a stroke includes effects that last at least 24 hours, whereas a TIA involves stroke symptoms that are resolved within a 24-hour period due to restoration of adequate blood flow.
