Stroke Signs and Symptoms: How to Recognize a Stroke Quickly

A stroke is a medical emergency that occurs when blood flow to the brain is interrupted, either by a clot (ischemic stroke) or bleeding (hemorrhagic stroke).

Without prompt treatment, brain cells begin to die within minutes. Recognizing the signs and symptoms of a stroke quickly can save lives and reduce long-term disability.

Here’s what everyone should know about stroke warning signs, risk factors, and what to do if you suspect a stroke is happening.

Why Stroke Recognition Is Critical

According to the CDC, someone in the U.S. has a stroke approximately every 40 seconds. Stroke is also a leading cause of death and long-term disability, especially among older adults—but it can occur at any age.

Early treatment is essential. The sooner a stroke is diagnosed and treated, the greater the chance of recovery. In some cases, clot-busting drugs like tPA can reverse or minimize damage, but only if given within a few hours of symptom onset.

The FAST Test: Spotting a Stroke in Seconds

The acronym FAST is a simple way to remember the most common warning signs of a stroke:

  • F – Face drooping: One side of the face may droop or feel numb. Ask the person to smile—does it appear uneven?
  • A – Arm weakness: One arm may be weak or numb. Ask them to raise both arms—does one drift downward?
  • S – Speech difficulty: Slurred speech or trouble speaking clearly. Ask them to repeat a simple phrase—does it sound strange?
  • T – Time to call 911: If any of these symptoms are present, call emergency services immediately.

Other Stroke Symptoms to Watch For

In addition to FAST symptoms, stroke can cause other sudden and unexplained changes, including:

  • Sudden numbness or weakness in the face, arm, or leg—especially on one side of the body
  • Confusion or trouble understanding speech
  • Vision problems in one or both eyes (blurred, blackened, or double vision)
  • Severe headache with no known cause (more common in hemorrhagic stroke)
  • Loss of balance, coordination, or dizziness
  • Difficulty walking or sudden falls

Even if symptoms disappear quickly (within minutes), it could be a transient ischemic attack (TIA) or "mini-stroke," which is a serious warning sign of future stroke risk.

Stroke Symptoms in Women

While both men and women share core stroke symptoms, women may experience additional or subtler warning signs, including:

  • Sudden nausea or vomiting
  • Hiccups
  • Chest pain
  • Shortness of breath
  • Heart palpitations
  • Sudden behavioral changes or confusion

Because these signs are sometimes mistaken for anxiety or fatigue, stroke in women is more likely to be misdiagnosed or delayed.

What to Do If You Suspect a Stroke

  1. Call 911 immediately. Do not wait to see if the symptoms improve.
  2. Note the time symptoms began. This is crucial for treatment eligibility.
  3. Stay calm and keep the person safe. Keep them lying down with their head slightly elevated if conscious.
  4. Do not give food, water, or medication. Swallowing may be impaired.
  5. Follow EMS instructions carefully.

Never attempt to drive someone having a stroke to the hospital yourself—it could delay or compromise care.

Stroke Risk Factors to Know

Major risk factors include:

  • High blood pressure (hypertension)
  • Smoking
  • Diabetes
  • High cholesterol
  • Atrial fibrillation
  • Obesity and physical inactivity
  • Excessive alcohol intake
  • Family history of stroke

Some risk factors are manageable through lifestyle changes, medication, and regular checkups. Early prevention is key.

Final Thoughts: Know the Signs, Act FAST

Strokes can happen without warning, but knowledge is the best defense. Recognizing stroke signs and symptoms—especially the FAST acronym—can save a life or prevent permanent brain damage.

Don’t wait. If you or someone near you shows any signs of a stroke, call 911 immediately. Quick action can mean the difference between recovery and long-term disability—or even life and death.
