A silent stroke, also known as a covert stroke or a clinically silent cerebral infarction, is a type of stroke that occurs without the person being aware of it. These strokes are often asymptomatic, meaning they do not present with the typical signs of a stroke, such as sudden weakness, numbness, or speech difficulties. However, they can still result in permanent damage to the brain. Silent strokes can be detected through medical imaging, such as MRI or CT scans, and they are often discovered incidentally during tests for other conditions. Over time, multiple silent strokes can accumulate and lead to cognitive issues, including problems with thinking and memory. read more >>
