<s>[INST] Symptoms of Cerebrovascular Disease [/INST] When plaque builds up in the carotid artery, blood flow to the brain may be impaired, increasing a patient’s risk of stroke. A brain aneurysm also increases a patient’s stroke risk. A stroke is damaged brain tissue caused by a vascular problem. There are many potential warning signs for stroke, including:

A sudden weakness or even paralysis of a leg, arm, or hand
Transient (lasting a short time) slurring, garbled, or inappropriate speech
Transient blindness or severe blurring of vision in one eye
A transient, one-sided facial droop
Other potential warning signs for stroke include blackout spells or severe headaches. Source: BRIGHAM AND WOMENS. Link: https://www.brighamandwomens.org/heart-and-vascular-center/diseases-and-conditions/heart-valve-disease. Field: Cardiovascular. Disease: Cerebrovascular Disease </s>
