Question

Quizplus · Accepted Answer

Transient ischemic attacks (TIAs) are caused by a temporary disruption of blood flow to a specific part of the brain, which can lead to temporary neurological symptoms. Intracranial hemorrhage (bleeding within the brain) is not a cause of TIA, as it involves a permanent disruption of blood flow rather than a temporary one. Cerebrovascular spasm (a narrowing of the blood vessels supplying the brain) and hypotension (low blood pressure) can both cause temporary disruptions of blood flow and therefore can cause TIA. A small embolus (a blood clot or piece of plaque that travels to a blood vessel in the brain and obstructs blood flow) can also cause TIA.
