 | | A transient ischemic attack is a "mini-stroke" caused by temporary disturbance of blood supply to an area of the brain, resulting in a sudden, brief decrease in brain function. |
 | | A transient ischemic attack (TIA) is caused by an interruption of blood flow to brain cells. |
 | | Less common causes of TIA include blood disorders (including polycythemia, sickle cell anemia, and hyperviscosity syndromes where the blood is very thick), spasm of the small arteries in the brain, abnormalities of blood vessels caused by disorders such as fibromuscular dysplasia, inflammation of the arteries (arteritis, polyarteritis, granulomatous angiitis), systemic lupus erythematosus, and syphilis. |
