Causes of Transient Ischemic Attack

The common cause of Transient Ischemic Attack is an embolus that obstructs an artery situated in the brain.  This situation arises due to a dislodged atherosclertic plaque in any of the numerous carotid arteries present in the neck and brain or from a blood clot or thrombus in the heart due to atrial fibrillation.

Other causes of TIA may include excessive narrowing of vessels due to atherosclerotic plaque and enhanced blood viscosity which may set in as a result of some blood diseases. Transient Ischemic Attack can be co related to a few other medical conditions such as hypertension, Migraine, heart disease such as atrial fibrillation, nicotine smoking, diabetes mellitus and hypercholesterolemia.
