Stroke Symptoms

 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 – Stroke is an emergency. Every minute counts. Call 911 immediately. Note the time when any of the symptoms first appear.

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

¿Qué es un accidente o derrame cerebral?

a digital illustration of characters communicating RÁPIDO

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.

Why is knowing F.A.S.T. stroke warning signs important?

FAST Face drooping Arm weakness Speech difficulty Time to call 911 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.

Are the symptoms of a stroke different for men and women?

stroke warning signs 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.

Can recognizing a stroke save your life? 

Woman holding her armIf 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 
  • Time to call 911
What are Silent Strokes and do they have symptoms?

Woman with her hand to her lips to indicate silence 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 CT.

How are the symptoms of strokes that occur in the back part of the brain (posterior circulation strokes) different?

Blurred group of people walking aroundPosterior 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).

Symptoms include:

  • 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
What are the signs and symptoms of a warning stroke (mini-stroke)? 

Hospital emergency signA 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.

Treat a Stroke F.A.S.T.

Stroke Hero – What’s Your Superpower

Instruction Manual to Become a Stroke Hero Trainer

Our mission is to empower the next generation to help save lives. Anyone — including our kids — can be a stroke hero. This kit is an easy-to-use resource for adults to empower youths to become stroke heroes.

In the toolkit, you’ll find everything you need to explain the following:

  • What is a stroke?
  • How do I recognize a stroke?
  • What should I do if someone is having a stroke?
  • How can we prevent stroke?

The good news is that quick treatment for stroke can save lives. Unfortunately, many patients aren’t eligible for the latest therapies because their symptoms aren’t recognized in time. Without treatment, the results of stroke can be devastating — life-altering deficits or even death.

By educating our kids, you’re using the superpower of teaching to create Stroke Heroes who can take action F.A.S.T. by recognizing:

  • Face drooping
  • Arm weakness
  • Speech difficulty
  • Time to call 911
Caregiver Resources
As a caregiver, you provide the most important long-term support for your stroke survivor’s recovery and rehabilitation. More than 53 million Americans are caregivers, and are as diverse as those they care for — spouses, partners, adult children, parents, siblings, grandchildren and family friends.
Cryptogenic Stroke
In most cases, a stroke is caused by a blood clot that blocks blood flow to the brain. In some instances, despite testing, the cause of a stroke can’t be determined. This is called a cryptogenic stroke.
Hemorrhagic Stroke
Hemorrhagic strokes account for about 13% of stroke cases. These strokes are caused by a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses brain tissue.
Ischemic Stroke
 Ischemic stroke occurs when a vessel supplying blood to the brain is obstructed. It accounts for about 87% of all strokes.
After a stroke, you may have to relearn or reconfigure the most basic tasks in life: dressing, driving, shopping, to name a few.
Stroke can change your life in an instant. But quality rehabilitation can help you recover. It’s important to make informed decisions about rehab quickly, which can be overwhelming. 
Transient Ischemic Attack (TIA)
TIA is a temporary blockage of blood flow to the brain. Since it doesn’t cause permanent damage, it’s often ignored. But that's a big mistake, because a TIA may signal a full-blown stroke ahead.
