Call 911 immediately. Do not drive yourself to the hospital, do not wait to see if symptoms pass, and do not call your doctor’s office first. Every minute without treatment, roughly 4 million neurons die. The single most important thing you can do during a stroke is get emergency medical services on the way as fast as possible.
While you wait for the ambulance, note the time your symptoms started. That number will directly determine which treatments are available to you.
How to Recognize Stroke Symptoms
The acronym BE FAST covers the major warning signs:
- Balance: Sudden loss of balance or coordination
- Eyes: Vision changes in one or both eyes, or sudden double vision
- Face: One side of the face droops when you try to smile
- Arms: One arm drifts downward when you raise both arms
- Speech: Slurred words, difficulty speaking, or trouble understanding what others are saying
- Time: Call 911 right now
These are the classic signs, but strokes don’t always look textbook. Women in particular are more likely to experience what researchers call “non-traditional” symptoms: sudden severe headache, nausea, disorientation, face or limb pain, generalized weakness, chest pain, fatigue, or a sudden change in consciousness. A study of over 1,100 stroke patients found women were significantly more likely than men to report these diffuse symptoms alongside or instead of the classic ones. If something suddenly feels very wrong in your body and you can’t explain it, treat it as an emergency.
Why You Should Call 911 Instead of Driving
Calling 911 does more than get you a ride. It activates the hospital’s stroke team before you even arrive. Paramedics radio ahead with your symptoms, and by the time the ambulance pulls in, a neurologist and emergency physician can be standing by, ready to evaluate you the moment you’re wheeled through the door. If you drive yourself or have someone drive you, the hospital has zero advance notice. You’ll check in, wait to be triaged, and lose precious time.
There’s another critical advantage. Paramedics can assess your symptoms on scene and route you to the right hospital. Not every emergency room can perform advanced stroke procedures. If EMS suspects a large blood vessel in your brain is blocked, they may bypass the closest hospital and take you directly to a comprehensive stroke center 20 or 30 miles away, getting you the intervention you need without a transfer delay that could cost hours.
What Happens When You Reach the ER
Hospitals operate on strict time targets once a stroke patient arrives. The goal is for a physician to see you within 10 minutes of walking through the door. Within 25 minutes, you should be getting a CT scan of your brain. Results from that scan are typically interpreted within 45 minutes of arrival. The entire sequence is designed to answer one urgent question: is this stroke caused by a blood clot blocking an artery, or by bleeding in the brain? The answer determines everything about your treatment.
Alongside the brain scan, the team draws blood to check clotting function, blood sugar, and electrolytes. A neurologist scores your symptoms on a standardized scale to measure stroke severity, then repeats that assessment at one hour, two hours, and 24 hours to track whether you’re improving or worsening. This all happens fast and simultaneously. You’ll feel like a lot of people are doing a lot of things to you at once, and that’s by design.
Why Every Minute Counts for Treatment
The phrase “time is brain” exists because the math is staggering. During an untreated ischemic stroke, your brain loses about 4 million neurons, 12 million brain cells total (including support cells), and 15 billion synaptic connections every single minute. The tissue that dies cannot be recovered. But the tissue surrounding the dead zone, called the penumbra, is still alive and salvageable if blood flow is restored quickly enough.
The primary clot-dissolving treatment has been used since the mid-1990s and works best when given within 3 hours of symptom onset. Later trials extended that window to 4.5 hours with still-meaningful benefit. More recently, guidelines have expanded options further: patients who wake up with stroke symptoms can potentially receive clot-dissolving treatment within 9 hours from the midpoint of sleep, as long as brain imaging shows there’s still tissue worth saving. For strokes caused by a large blocked vessel, a procedure to physically remove the clot can be performed up to 24 hours after symptoms began in carefully selected patients whose imaging shows salvageable brain tissue.
These extended windows are encouraging, but they apply to fewer patients and require advanced imaging to qualify. The earlier you arrive, the more treatment options remain on the table and the more brain tissue can be saved. A person treated at 90 minutes will almost always have a better outcome than someone treated at 4 hours, even though both fall within the window.
What Not to Do
Do not take aspirin or any other medication while waiting for help. You don’t yet know whether your stroke is caused by a clot or by bleeding, and aspirin could make a bleeding stroke catastrophically worse. Do not eat or drink anything, because you may need emergency procedures and swallowing function can be impaired during a stroke without you realizing it. Do not lie flat if you’re having trouble breathing; try to stay seated or prop yourself up. If you’re alone, unlock your front door so paramedics can get in, then sit or lie down somewhere safe where you won’t fall.
Do not let embarrassment or uncertainty stop you from calling 911. Roughly 25% of strokes happen to people under 65. Symptoms that resolve on their own within minutes might be a transient ischemic attack (TIA), sometimes called a mini-stroke, and that is still an emergency. About 10 to 15% of people who experience a TIA will have a full stroke within three months, and half of those strokes happen within 48 hours. A TIA is a warning that demands immediate evaluation, not relief that it passed.
What to Tell the 911 Dispatcher
Keep it simple and specific. Tell them you think you or someone near you is having a stroke. State the symptoms you’re seeing: face drooping, arm weakness, slurred speech, vision changes, sudden imbalance. Give them the exact time symptoms started, or the last time the person was known to be normal. If you don’t know when symptoms started (for instance, the person woke up this way), say that clearly. This information gets relayed to the hospital and directly affects treatment decisions.
If you’re with someone else who is showing stroke signs, stay with them, keep them calm, and note any changes in their symptoms. Don’t let them talk you out of calling 911. People mid-stroke often deny something is wrong or resist going to the hospital. Their judgment may be impaired by the very event happening in their brain. Trust what you’re seeing over what they’re telling you.
