Stroke (CVA)
That is brought on by blockage of blood flow to the brain. It might be related to damage to the blood vessels, blood clots blocking the passage, or a narrowing because of the presence of plaques with fatty deposits.
It’s generally known as a transient stroke is a brief blockage by which symptoms last from just a few minutes to a maximum of 24 hours. Following a stroke or transient ischemic attack, there’s a high probability of getting one other stroke in the longer term.
