00:04A transient ischemic attack, or TIA, is often called a mini-stroke.
00:09TIA is a condition caused by a disrupted blood supply to the brain, which results in neurological
00:14symptoms that typically resolve within an hour, and often within minutes.
00:18The defining difference between a TIA and an actual stroke is that TIAs do not result
00:23in a brain infarct or death of brain tissue, while a true stroke does.
00:29TIAs are caused by a temporary reduction in blood flow to part of the brain, often due
00:33to a small blood clot or a piece of an atherosclerotic plaque that briefly obstructs a cerebral artery
00:38and then breaks apart or becomes dislodged on its own.
00:42Because neurons depend on a constant supply of oxygen and glucose, even a short interruption
00:47can disrupt brain function.
00:50Symptoms depend on the brain region affected, but are the same as those seen in stroke.
00:53These may include, but are not limited to, sudden weakness, paralysis, or numbness in the face
00:59or limbs, often on one side of the body, difficulty speaking or understanding language, blindness
01:05in one or both eyes, dizziness, and a loss of balance or coordination.
01:10In a transient ischemic attack, these symptoms fully resolve in a relatively short period of
01:15time.
01:17Because symptoms of a TIA can be indistinguishable from a stroke, a TIA should be treated as a
01:22medical emergency.
01:24Brain imaging and a comprehensive evaluation are typically used to determine if an actual
01:29stroke occurred and other tests are done to determine what might have caused the TIA.
01:34Although a TIA doesn't result in any damage to the brain, the risk of a stroke occurring
01:39after TIA is substantially higher, especially with inadequate treatment of the TIA.
01:43Thus patients are assessed for stroke risk and treated to prevent future stroke.
01:50With respect to the recovery here, we all have to collect.
01:59So
