Women have a higher lifetime risk of having a stroke than men. Learn more about recognizing the signs of stroke in women. Stroke is the fifth-leading cause of death in men. Men and women can have some of the same signs and symptoms of stroke see above. However, some stroke symptoms occur more often in men.
These include:. Learn more about the signs of a stroke in men. Strokes fall into three main categories : transient ischemic attack TIA , ischemic stroke, and hemorrhagic stroke. These categories are further broken down into other types of strokes, including:. The type of stroke you have affects your treatment and recovery process. Read more about the different types of strokes.
During an ischemic stroke, the arteries supplying blood to the brain narrow or become blocked. They can also be caused by pieces of plaque due to atherosclerosis breaking off and blocking a blood vessel. The two most common types of ischemic strokes are thrombotic and embolic. A thrombotic stroke happens when a blood clot forms in one of the arteries supplying blood to the brain. The clot passes through the bloodstream and becomes lodged, which blocks blood flow.
An embolic stroke is when a blood clot or other debris forms in another part of the body and then travels to the brain.

According to the CDC, 87 percent of strokes are ischemic strokes. Find out why ischemic strokes occur. An embolic stroke is one of two types of ischemic strokes. It occurs when a blood clot forms in another part of the body — often the heart or arteries in the upper chest and neck — and moves through the bloodstream to the brain.

An embolic stroke may be the result of a heart condition. Atrial fibrillation , a common type of irregular heartbeat, can cause blood clots to develop in the heart. These clots may dislodge and travel through the bloodstream and into the brain. Read more about how embolic strokes occur and the symptoms they can cause. A transient ischemic attack , often called a TIA or ministroke, occurs when blood flow to the brain is blocked temporarily.
Symptoms, which are similar to those of a full stroke, are typically temporary and disappear after a few minutes or hours. A TIA is usually caused by a blood clot. Seek the same treatment you would for a major stroke and call Up to 10 to 15 percent of people who experience a TIA have a major stroke within three months.
A hemorrhagic stroke happens when an artery in the brain breaks open or leaks blood. The blood from that artery creates excess pressure in the skull and swells the brain, damaging brain cells and tissues. The two types of hemorrhagic strokes are intracerebral and subarachnoid. An intracerebral hemorrhagic stroke, the most common type of hemorrhagic stroke, happens when the tissues surrounding the brain fill with blood after an artery bursts.
The subarachnoid hemorrhagic stroke is less common. It causes bleeding in the area between the brain and the tissues that cover it. According to the American Heart Association, about 13 percent of strokes are hemorrhagic. Learn more about the causes of hemorrhagic stroke, as well as treatment and prevention.
The cause of a stroke depends on the type of stroke. The three main types of stroke are transient ischemic attack TIA , ischemic stroke, and hemorrhagic stroke. A TIA is caused by a temporary blockage in an artery that leads to the brain. The blockage, typically a blood clot, stops blood from flowing to certain parts of the brain.
A TIA typically lasts for a few minutes up to a few hours, and then the blockage moves and blood flow is restored. Like a TIA, an ischemic stroke is caused by a blockage in an artery that leads to the brain. This blockage may be a blood clot, or it may be caused by atherosclerosis. With this condition, plaque a fatty substance builds up on the walls of a blood vessel.

A piece of the plaque can break off and lodge in an artery, blocking the flow of blood and causing an ischemic stroke. A hemorrhagic stroke, on the other hand, is caused by a burst or leaking blood vessel. Blood seeps into or around the tissues of the brain, causing pressure and damaging brain cells.

There are two possible causes of a hemorrhagic stroke. An aneurysm a weakened, bulging section of a blood vessel can be caused by high blood pressure and can lead to a burst blood vessel. Less often, a condition called an arteriovenous malformation , which is an abnormal connection between your veins and arteries, can lead to bleeding in the brain. Keep reading about the causes of different types of strokes.
Certain risk factors make you more susceptible to stroke. According to the National Heart, Lung, and Blood Institute , the more risk factors you have, the more likely you are to have a stroke.
Risk factors for stroke include:. Regular exercise has a number of health benefits. The CDC recommends that adults get at least 2. This can mean simply a brisk walk a few times a week. Your risk for stroke also increases if you drink too much alcohol. Alcohol consumption should be done in moderation. This means no more than one drink per day for women, and no more than two for men.

More than that may raise blood pressure levels as well as triglyceride levels, which can cause atherosclerosis. Using tobacco in any form also raises your risk for stroke, since it can damage your blood vessels and heart. This is further increased when smoking , because your blood pressure rises when you use nicotine.
Stroke risk can be linked to your:. To find out about your specific risk factors for stroke, talk to your doctor. In the meantime, find out what you can do to lower your risk of stroke. Your doctor will ask you or a family member about your symptoms and what you were doing when they arose.
Your doctor will then do certain tests. A variety of tests are used to aid in diagnosis of a stroke. These tests can help doctors determine:. These tests include:.
You may undergo either or both a magnetic resonance imaging MRI scan and a computerized tomography CT scan. The MRI will help see if any brain tissue or brain cells have been damaged. A CT scan will provide a detailed and clear picture of your brain that shows any bleeding or damage in the brain. It may also show other brain conditions that could be causing your symptoms.
Your doctor may order an electrocardiogram EKG , too. This simple test records the electrical activity in the heart, measuring its rhythm and recording how fast it beats.
