A stroke is a medical emergency where every second counts. It occurs when blood flow to a part of the brain is interrupted, either by a blood clot or a ruptured blood vessel. When brain cells are deprived of oxygen and nutrients, they begin to die within minutes. Knowing the signs of a stroke and what to do immediately can be the difference between a full recovery and a life-altering disability or even death. The most important thing to remember is the acronym F.A.S.T., a simple and effective tool for recognizing the symptoms of a stroke.
F.A.S.T.: The Key to Recognition
F – Face Drooping: Ask the person to smile. Does one side of their face droop or feel numb? This is one of the most common and recognizable signs of a stroke.
A – Arm Weakness: Ask the person to raise both arms. Does one arm drift downward or feel weak and numb? A person suffering a stroke may not be able to lift one arm or keep it raised.
S – Speech Difficulty: Ask the person to repeat a simple sentence. Is their speech slurred, strange, or difficult to understand? They may have trouble finding the right words or speaking clearly.
T – Time to call 911: If the person shows any of these symptoms, even if they are temporary, it is time to call 911 immediately. Do not wait to see if the symptoms go away.
What to Do to Help and Prevent Further Harm
Once you recognize the signs of a stroke, your immediate actions are critical. The goal is to get the person to a hospital that is a certified stroke center as quickly as possible. The saying “time is brain” is not just a slogan—it reflects the reality that for every minute a stroke goes untreated, the brain loses a significant number of neurons.
- Call 911 Immediately: This is the most important step. Do not drive the person to the hospital yourself. Emergency medical services (EMS) are trained to care for stroke patients on the way to the hospital and can alert the hospital’s stroke team to prepare for their arrival. This saves crucial time.
- Note the Time: Try to remember the exact time the symptoms first appeared. This information is vital for doctors, as it determines which treatments, such as clot-busting medications (tPA), are an option.
- Keep the Person Comfortable: While waiting for help to arrive, keep the person calm and in a comfortable position, ideally with their head slightly elevated to reduce pressure on the brain. Do not give them any food, water, or medication, as a stroke can affect their ability to swallow.
- Do Not Drive Yourself: It bears repeating: do not attempt to drive the person yourself. You are not equipped to handle a medical emergency, and the delay in care could lead to a worse outcome.
In a stroke, every moment matters. By learning and remembering the F.A.S.T. acronym and knowing how to respond, you can be a hero who helps prevent as much future harm as possible. Sources
