TRANSIENT ISCHEMIC ATTACK
Definition
A Transient Ischemic Attack, generally referred to as a TIA, is a type of stroke that only last a few minutes. They are sometimes called ¡§mini-strokes.¡¨ The term transient is used to describe a condition that lasts only a short amount of time. Ischemic describes an inadequate blood flow. Therefore, TIA is a deprivation of blood to the brain for a short period of time.
General Information
Transient Ischemic Attacks occur in the same way as an ischemic stroke. Both occur when the blood supply to part of the brain is blocked, which is why a stroke is known as a cerebrovascular accident. ¡§Cerebro¡¨ refers to a part of the brain. ¡§Vascular¡¨ refers to the blood vessels and arteries.
Conversely, TIAs occur when blood flow to the brain is reduced for a short period of time. Therefore, a TIA resolves, leaving no noticeable symptoms or disabilities. This temporary blockage is typically caused by a spasm of a brain artery, causing it to narrow. However, it is also common for this blockage to be cause by a small blood clot in an artery.
The average duration of a TIA is said to be a few minutes, however, it this has recently been corrected. By definition a transient ischemic attack could have symptoms that last up to a maximum of 24 hours.
TIAs typically serve as a warning sign. Any individual who has had a TIA is at an elevated risk for a more serious and debilitating stroke.
Signs and Symptoms of a Transient Ischemic Attack
Signs and symptoms of a TIA are superfluous, and hard to recognize by most doctors. In 1999 The National Institute of Neurological Disorders and Stroke (NINDS) has come to the conclusion that there is no
