Watershed stroke is a type of stroke that happens in the watershed area of blood supply in the brain between the various major arteries that supply blood to the brain such as middle cerebral artery, anterior cerebral artery, posterior cerebral artery and the circle of Willis.

About Stroke[edit | edit source]

A stroke happens when a blood clot blocks blood flow to the brain. This causes brain tissue to become damaged or die.

Stroke ischemic

Other names[edit | edit source]

A stroke, sometimes called a brain attack, occurs when something blocks blood supply to part of the brain or when a blood vessel in the brain bursts. In either case, parts of the brain become damaged or die. A stroke can cause lasting brain damage, long-term disability, or even death.

The brain[edit | edit source]

The brain controls our movements, stores our memories, and is the source of our thoughts, emotions, and language. The brain also controls many functions of the body, like breathing and digestion.

To work properly, your brain needs oxygen. Although your brain makes up only 2% of your body weight, it uses 20% of the oxygen you breathe.1 Your arteries deliver oxygen-rich blood to all parts of your brain.

How stroke happens[edit | edit source]

If something happens to block the flow of blood, brain cells start to die within minutes because they can’t get oxygen. This causes a stroke.

There are two types of stroke:

An ischemic stroke occurs when blood clots or other particles block the blood vessels to the brain. Fatty deposits called plaque can also cause blockages by building up in the blood vessels.

A hemorrhagic stroke occurs when a blood vessel bursts in the brain. Blood builds up and damages surrounding brain tissue. Both types of stroke damage brain cells. Symptoms of that damage start to show in the parts of the body controlled by those brain cells.

Quick Treatment Is Critical for Stroke[edit | edit source]

A stroke is a serious medical condition that requires emergency care.
