Stroke is a medical emergency that happens when blood flow to part of the brain is suddenly blocked or when a blood vessel in the brain bursts.
Without enough oxygen, brain cells begin to die within minutes. Fast treatment is very important because it can reduce brain damage and improve the chances of recovery.
Older adults have a higher risk of stroke because blood vessels naturally change with age. Many seniors also have conditions such as high blood pressure, diabetes, high cholesterol, or an irregular heartbeat, all of which increase the risk. Learning the early warning signs can help save a life.
An easy way to remember the main symptoms is the word FAST. The letter F stands for face drooping. If one side of the face looks uneven or droops when a person smiles, it may be a sign of a stroke.
A stands for arm weakness. Ask the person to raise both arms. If one arm cannot stay up or slowly falls down, they may be having a stroke.
S stands for speech problems. Speech may become slurred, confused, or difficult to understand. The person may also struggle to find the right words or understand what others are saying.
T stands for time to call emergency services immediately. Do not wait to see if the symptoms go away. The sooner treatment begins, the better the chance of protecting the brain.
There are also other warning signs. A person may suddenly become confused, lose vision in one or both eyes, feel dizzy, lose balance, or have trouble walking. A sudden, very severe headache with no clear cause can be a sign of bleeding in the brain, known as a hemorrhagic stroke.
Research has shown that every minute counts. A study published in The New England Journal of Medicine found that people treated within three hours of their first stroke symptoms had much better outcomes than those who received treatment later. Early treatment can restore blood flow in many strokes caused by blood clots.
Some people experience a transient ischemic attack, or TIA, often called a mini-stroke. The symptoms are similar to a stroke but usually disappear within minutes or hours. Even though the symptoms go away, a TIA is a serious warning that a major stroke could happen soon.
According to the American Stroke Association, about one in three people who have a TIA will have a full stroke within one year if the cause is not treated. Anyone with TIA symptoms should seek medical care right away, even if they feel better.
The risk of stroke can often be reduced by managing health problems. Keeping blood pressure under control is one of the most important steps because high blood pressure is the leading cause of stroke. Eating a healthy diet, staying active, maintaining a healthy weight, not smoking, and controlling cholesterol and diabetes also help protect the brain.
For people with atrial fibrillation, a common heart rhythm problem, taking prescribed blood-thinning medicine can greatly lower the risk of stroke. Doctors can recommend the best treatment based on each person’s health and risk factors.
Overall, recognizing stroke symptoms quickly and acting FAST can save lives. Never ignore sudden face drooping, arm weakness, speech problems, vision changes, confusion, or a severe headache. The research published in The New England Journal of Medicine highlights the importance of getting emergency treatment as quickly as possible.
