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.
A naturally occurring protein that blocks an inflammatory immune response was associated with better stroke recovery in a study conducted in mice, according to preliminary research to be presented at the American Heart Association's Vascular Discovery: From Genes to Medicine Scientific Sessions 2021.
