Understanding Stroke

What is Stroke?

Symptoms of Stroke - VHL HealthSheet #82577_VA
During a stroke, blood stops flowing to part of the brain. This can damage areas in the brain that control the rest of the body. Call 911 and get help right away if any of these symptoms come on suddenly, even if the symptoms don’t last.
Understanding Dysphagia - VHL HealthSheet #82959_VA
If you have a problem swallowing foods or liquids, you may have dysphagia.
What Is Aphasia? - VHL HealthSheet #82575_VA
Aphasia is a loss of language skills. It may happen if the brain is damaged. This usually happens after a stroke. It can also happen from brain injury, tumors, or neurological disorders.
What Is Dysarthria? - VHL HealthSheet #82581_VA
Dysarthria is a speech problem caused by a weakness or a lack of control over muscles in the face, mouth, and respiratory system. Dysarthria may be congenital (present at birth) because of a disorder such as cerebral palsy or the result of a stroke or brain injury.
Stroke - VHL Video
A stroke occurs when either too much blood or too little blood disrupts blood flow to part of the brain. This deprives brain tissue of necessary oxygen and nutrients. Within minutes brain cells begin to die and the result is a loss of brain function.
Carotid Artery Disease - VHL Video
Carotid artery disease means that a large blood vessel in your neck is partly blocked. You may not have symptoms. But the condition is serious because it can lead to a stroke.
