An ischemic stroke occurs when the blood supply to part of the brain is blocked or reduced. This prevents brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes. Another type of stroke is a hemorrhagic stroke. It occurs when a blood vessel in the brain leaks or bursts and causes bleeding in the brain. The blood increases pressure on brain cells and damages them.
The patient with a stroke will typically start therapies very early after a stroke, including physical therapy, occupational therapy, and speech therapy. A person can continue to recover from a stroke for many months after a stroke up to a year or even longer. This recovery is a very gradual process. But don't give up.
Most often, a ruptured brain aneurysm happens in the space between the brain and the thin tissues covering the brain. This type of hemorrhagic stroke is called a subarachnoid hemorrhage. Brain aneurysms are common. But most brain aneurysms aren't serious, especially if they're small. Most brain aneurysms don't rupture. They usually don't cause symptoms or cause health problems. In many people ...
Carotid artery disease occurs when fatty deposits, called plaques, clog the blood vessels that deliver blood to the brain and head (carotid arteries). These clogged blood vessels increase the risk of stroke. Stroke is a medical emergency that happens when the brain loses all or much of its blood supply.
Heatstroke needs emergency care. If it's not treated, heatstroke can quickly damage the brain, heart, kidneys and muscles. This damage gets worse the longer treatment is delayed, which increases the risk of serious complications or death.
