By learning and sharing the F.A.S.T. warning signs, you just might save a life from stroke.
Call 911 if these signs are present
F.A.S.T. Warning Signs
Use the letters in F.A.S.T. to spot a Stroke
- F = Face Drooping – Does one side of the face droop or is it numb? Ask the person to smile. Is the person's smile uneven?
- A = Arm Weakness – Is one arm weak or numb? Ask the person to raise both arms. Does one arm drift downward?
- S = Speech Difficulty – Is speech slurred?
- T = Time to call 911
Other Stroke Symptoms
Watch for Sudden:
- NUMBNESS or weakness of face, arm, or leg, especially on one side of the body
- CONFUSION, trouble speaking or understanding speech
- TROUBLE SEEING in one or both eyes
- TROUBLE WALKING, dizziness, loss of balance or coordination
- SEVERE HEADACHE with no known cause
Take the CPR Challenge to Save Lives
Nearly 3 out of 4 cardiac arrests that don't happen in hospitals, happen in homes. You can help change this statistic. Join American Heart Association's challenge to the be the one in your household to learn CPR. Be the beat for someone you love.

Un accidente o derrame cerebral ocurre cuando se bloquea el flujo de sangre en las arterias que nutren el cerebro, o cuando ocurre un sangrado en el cerebro mismo o en las membranas que lo rodean.
Las mujeres, los hispanos y los afroamericanos en los Estados Unidos tienen mayor riesgo para el accidente o derrame cerebral.
Stroke is the No. 5 cause of death and a leading cause of disability in the U.S. Stroke can happen to anyone — any age, any time — and everyone needs to know the warning signs.
On average, 1.9 million brain cells die every minute that a stroke goes untreated.
Stroke is an EMERGENCY.
Call 911 immediately.
Early treatment leads to higher survival rates and lower disability rates. Calling 911 lets first responders start treatment on someone experiencing stroke symptoms before arriving at the hospital.
Men and women who have strokes often feel similar symptoms of stroke, such as face drooping, arm weakness and speech difficulty.
Other common signs for both women and men include problems seeing out of one or both eyes and balance or coordination problems.
Women can also experience:
- General weakness
- Disorientation and confusion or memory problems
- Fatigue, nausea or vomiting
However, some signs of stroke in women can be subtle enough to be missed or brushed off. That can lead to delays in getting time-sensitive, lifesaving treatments.
If you’re having a stroke, it’s critical that you get medical attention right away. Immediate treatment may minimize the long-term effects of a stroke and even prevent death.
Thanks to recent advances, stroke treatments and survival rates have improved greatly over the last decade.
But in order to seek treatment, you must recognize the signs and symptoms of a stroke and know what to do:
- Face drooping
- Arm difficulty
- Speech slurring

Silent strokes are undetected strokes. They occur when a blood vessel blockage in the brain causes cells to die, but no warning signs or symptoms are obvious.
About one-fourth of people over age 80 have at least one such area of tissue death, known as a "silent infarct," in the brain. The condition is more common with increasing age, and in people who smoke or have a history of vascular disease (conditions that affect your blood vessels).
Experts estimate that 10 silent strokes occur for every stroke with detectable symptoms. Despite being called "silent," these infarcts have been linked to subtle problems in a person's movement and mental processing. They also are linked to future risk for stroke and dementia.
Silent infarcts can be seen in patients through advanced brain imaging techniques such as MRI and CTLearn more about the effect of stroke.
Posterior circulations strokes (a stroke that occurs in the back part of the brain) occur when a blood vessel in the back part of the brain is blocked, causing the death of brain cells (called an infarction) in the area of the blocked blood vessel.
This type of stroke can also be caused by a ruptured blood vessel in the back part of the brain. When this type of stroke happens, several symptoms occur and they can be very different than the symptoms that occur in the blood circulation to the front part of the brain (called anterior circulation strokes).
- Vertigo, sensation like the room is spinning Imbalance or one-sided arm or leg weakness
- Slurred speech or difficulty in speech (dysarthria)
- Double vision or other vision problems
- A headache Nausea and/or vomiting
A transient ischemic attack (TIA) is a warning stroke, but is commonly referred to by the public as a mini-stroke.
TIA is a medical emergency with the same symptoms as ischemic and hemorrhagic strokes. Because most TIA symptoms last from only a few minutes up to 24 hours, they are often dismissed and not taken seriously.
TIAs, which occur before about 15% of strokes, are considered "warning strokes" — they are associated with additional TIAs, full-blown strokes or other cardiovascular problems later. Most of these later health problems happen within just days or weeks of the TIA, so early interventions to reduce risk are vital.
Remember "F.A.S.T." to know when to call for help:
- F = Face drooping
- A = Arm weakness
- S = Speech difficulty
- T = Time to call 911
If you or someone with you is experiencing these or other stroke symptoms, urgent medical evaluation and treatment are needed. Check the time so you'll know when the first symptoms appeared.
Call 911 even if the symptoms go away.

Additional Stroke Warning Signs
Effects of Stroke
The effects of a stroke depend on several factors, including the location of the obstruction and how much brain tissue is affected. However, because one side of the brain controls the opposite side of the body, a stroke affecting one side will result in neurological complications on the side of the body it affects.
Life After Stroke
While strokes can vary in type and severity, many patients and their loved ones have been where you are now – facing important decisions about rehab that must be made quickly. Stroke recovery can seem overwhelming, but rehabilitation can help you regain your strength, your courage and your independence.
Stroke Risk Factors
Stroke is dangerous and deadly — the No. 5 killer and a leading cause of disability in America. But you can control and treat several risk factors for stroke.

Types of stroke and treatment
In leading causes of U.S. death, stroke used to rank fourth. Now it's fifth. The higher survival rates are largely due to medical treatment advances.
The right care — done the right away — can save both lives and quality of life.
