Stroke

Besides heart attacks, atherosclerosis can also lead to strokes. Hyperlipidemia, or high cholesterol, directly increases the risk of stroke, especially when combined with other conditions such as hypertension, or high blood pressure.

The plaques that can result from hyperlipidemia often contribute to the most common type of stroke, called an ischemic stroke. During an ischemic stroke, a piece of plaque or blood clot blocks an artery into the brain.

A second type of stroke is called a hemorrhagic stroke, and is caused by a ruptured blood vessel within the brain.

The result of either type of stroke is that part of the brain is injured or dies from lack of blood flow and oxygen.

Symptoms of a stroke may include sudden numbness or weakness of the face, arm or leg, especially on one side of the body. Stroke symptoms also may include sudden confusion, trouble speaking or understanding, sudden vision problems, dizziness, loss of balance, or an abrupt, unusually severe headache.

Although some stroke damage is reversible, ischemic and hemorrhagic strokes can both result in part of the brain dying from lack of blood and oxygen. This affects the part of the body that is controlled by the damaged part of the brain. For those who survive, stroke can cause paralysis, affect language and vision, and cause a variety of other problems.

Keep in mind, it’s possible to protect against a stroke. Knowing and reducing your risk factors, such as high cholesterol, can lower your risk. Ask your healthcare provider for more information about stroke and its warning signs.
