Stroke

This is a slow down or blockage of the blood that normally flows to part of your brain. When it happens, your brain cells don't get the oxygen and nutrients they need. Within minutes, they begin to die.

Learn what a TIA is, how it is a serious warning sign for a stroke, and the importance of calling 911 if someone is showing the signs of having a TIA.

A transient ischemic attack (TIA), also called a ministroke stroke, causes symptoms similar to those of a stroke. The difference is that TIAs don't cause permanent brain damage. This video explains what happens during a TIA, what you should do if you have symptoms, and what treatment is available.

Your risk for stroke is tied to a lot of factors. Some things (like your age and family history) you can't control. But you do have control over many others. So if you're worried about your risk, focus on these healthy habits.

The effects of a stroke and how long they may last depend on several factors, including the location and size of the brain injury, the quality and quantity of medical care received, the strength of one's support circle and his/her will to get better. © AHA

Stroke is the fifth leading cause of death in America today. It's also a major cause of severe, long-term disability. To protect yourself and your loved ones from the serious effects of stroke, you should learn your risk factors, reduce your risk factors, learn the warning signs of stroke and know what to do if you notice warning signs. © AHA

During a stroke, fast action is key. Getting help quickly can be the difference between life and death. Fortunately, there are many warning signs that show you a stroke is happening. So get help immediately if you notice any of the following symptoms.

This is bleeding that happens inside your brain. Most often, it's a rupture of tiny arteries in your brain. It can happen deep within the brain, or near the brain's surface. It leads to stroke and to a dangerous buildup of pressure in the brain.

This is bleeding that happens between your brain and the membrane that surrounds it. It leads to stroke and to a dangerous buildup of pressure in your brain.

It's critical to diagnose a stroke in progress because the treatment for stroke depends on the type of stroke, and, in some cases, the location of the injury to the brain. Other conditions with similar symptoms to stroke and transient ischemic attack (TIA) will need to be ruled out to diagnose stroke. Some of these include seizures, fainting, migraine headaches, heart problems or other general medical conditions. © AHA

About 13 percent of strokes happen when a blood vessel ruptures in or near the brain. This is called a hemorrhagic stroke. When a hemorrhagic stroke happens, blood collects in the brain tissue. This is toxic for the brain tissue causing the cells in that area to weaken and die. © AHA

High blood pressure means that the force of the blood pushing against the blood vessel walls is consistently in the high range. Uncontrolled HBP can lead to stroke, heart attack, heart failure or kidney failure. © AHA

The majority of strokes occur when blood vessels to the brain become narrowed or clogged with fatty deposits called plaque. This cuts off blood flow to brain cells. A stroke caused by lack of blood reaching part of the brain is called an ischemic stroke. High blood pressure is a leading risk factor for ischemic stroke. © AHA

A transient ischemic attack (TIA) is often called a mini-stroke, but it's really a warning stroke. TIA and stroke symptoms are the same, although most TIA symptoms last only a few minutes (but up to 24 hours). While TIAs generally do not cause permanent brain damage, they are major warnings and should not be ignored. © AHA

Many strokes may be prevented through blood pressure control, a healthy diet, regular physical activity and smoking cessation. Each plays a big part in decreasing your risk for stroke, disability or even death. © AHA

There are risk factors that can lead to stroke that you can control and risk factors you can't control. Learn which ones you can change or treat and know which risk factors are out of your control. © AHA

A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. It can cause permanent disability or even death. Although stroke is the fifth-leading cause of death, Hispanic people in the U.S. face an even higher risk. It's the No. 4 cause of death for Hispanic men and No. 3 for women. © AHA

Stroke — the fifth leading cause of death in America — is a "brain attack" that occurs when blood that brings oxygen to your brain stops flowing and brain cells die. Black Americans have a higher prevalence of stroke and highest death rate from stroke than any other racial group. © AHA

Adults who have diabetes are two times as likely to have a stroke compared to people who do not have diabetes. The connection between diabetes and stroke has to do with the way the body handles blood glucose to make energy. © AHA

Stroke occurs when a blood vessel bringing blood and oxygen to the brain gets blocked by a clot or ruptures. When this happens, brain cells don't get the blood and oxygen that they need to survive. This causes nerve cells to stop working and die within minutes. Then, the part of the body they control are affected. The effects of stroke may be permanent depending on how many cells die, where they are in the brain, and other factors. © AHA

It is a brief and easy-to-use tool, intended for completion with the patient and the help of a caregiver, if necessary. © AHA

A hemorrhagic stroke happens when a blood vessel in the brain ruptures or leaks. A blood vessel on the surface of the brain bursts (hemorrhages). This spills blood into the surrounding tissue. This type of stroke often happens suddenly, with little warning.

The earlier treatment for a stroke is started after symptoms begin, the more likely you are to survive and recover. Here is what you can expect during treatment.

Every part of your body, including your heart and your brain, needs oxygen to work. Oxygen is carried in the blood. Blood vessels called arteries carry oxygen-rich blood throughout the body. Both heart attack and stroke are due to problems in the arteries. The same factors that cause heart disease can make you more likely to have a stroke.

This type of stroke can have a wide range of effects in the body and cause a broad range of symptoms.

Most strokes are caused by a blockage in a blood vessel that supplies the brain. They can also occur if a blood vessel in the brain ruptures (bursts open).

A TIA (transient ischemic attack) is an early warning that a stroke (also called a brain attack) is coming. A TIA is a temporary stroke. It causes no lasting damage. But the effects of a stroke, if it happens, can be very serious and lasting. Here are symptoms to watch for.
