A stroke is one of the most time-sensitive emergencies in medicine. Recognizing it within minutes, not hours, can be the difference between full recovery and lasting brain injury. The F.A.S.T. method makes recognition simple enough for anyone to use.
This guide covers what a stroke is, how to spot one, what to do in the first 5 minutes, and what happens when you arrive at the ER of Irving.
What is a Stroke? Why Every Minute Counts
A stroke happens when blood flow to part of your brain stops. The brain tissue without blood begins dying within minutes, and the damage spreads fast.
On average, 1.9 million brain cells die every minute that a stroke goes untreated, according to the American Stroke Association. That is why doctors say “time is brain.” The earlier someone gets to an ER, the more brain tissue can be saved.
Strokes come in two main forms. An ischemic stroke is caused by a clot blocking a brain artery. A hemorrhagic stroke is caused by a brain artery bursting. Both are emergencies, but they need different treatments at the ER.
The F.A.S.T. Method: 4 Warning Signs of Stroke
The CDC and the American Stroke Association both promote F.A.S.T. as the fastest way to recognize a stroke. Each letter points to one thing to check.
- F – Face drooping. Ask the person to smile. Does one side of the face droop or feel numb?
- A – Arm weakness. Ask them to raise both arms. Does one arm drift downward or feel heavy?
- S – Speech difficulty. Ask them to repeat a simple sentence like “the sky is blue.” Are the words slurred or jumbled?
- T – Time to call 911. Even if symptoms seem to fade, call. Note the exact time symptoms started.
Any one of these signs is enough to call. You do not need all four.
Atypical Stroke Symptoms You Should Not Miss
F.A.S.T. does not catch every stroke. The American Stroke Association warns that some signs of stroke in women can be subtle enough to be missed.
Women can also have general weakness, confusion or memory problems, fatigue, nausea, or vomiting. Younger adults can have strokes too. Vision loss in one eye, sudden severe dizziness, or trouble walking should not be brushed off.
Posterior strokes affect the back of the brain. The same ASA page lists vertigo, imbalance, double vision, headache, and nausea or vomiting. Silent strokes cause no obvious symptoms, but MRI and CT brain imaging can show them.
If something is sudden and severe, call 911. Even atypical strokes need the same urgent ER pathway.
Ischemic vs Hemorrhagic Stroke: Why the Difference Matters
The two types of stroke need opposite treatments. That is why the ER team moves fast to identify which one is happening.
About 80% of strokes are ischemic, per MedlinePlus. A blood clot blocks an artery in the brain. Doctors may use a clot-dissolving medicine called tPA, but MedlinePlus notes it can only be given within 4 hours of when symptoms started.
The remaining strokes are hemorrhagic. A brain blood vessel ruptures and bleeds. Per MedlinePlus, treatment focuses on stopping the bleeding. If high blood pressure is the cause, blood pressure medicines may be given.
A CT or MRI scan of the brain shows where the stroke is and whether there is bleeding, per the MedlinePlus stroke guide.
The First 5 Minutes: Exactly What To Do
What you do in the first 5 minutes matters more than almost anything else.
- Call 911 immediately. Do not call a friend or search online. Just dial.
- Note the exact time symptoms started. Or the last time the person was definitely normal. The CDC says this helps health care providers determine the best treatment.
- Stay with them. Help them sit or lie down safely. Loosen tight clothing.
- Track any changes. Symptoms can worsen quickly. Tell the paramedics what changed.
- Do not give food, water, or medicine. Stroke can cause problems swallowing, per MedlinePlus.
What Not To Do: 4 Mistakes That Cost Critical Minutes
These four mistakes happen often and waste the only thing that matters: time.
- Don’t drive them yourself. The CDC says to call 9-1-1 so medical personnel can begin life-saving treatment on the way.
- Don’t give aspirin. Some strokes are caused by bleeding. A brain scan at the ER checks for bleeding before treatment is chosen.
- Don’t wait to see if it passes. Symptoms that fade can be a TIA, or mini-stroke. Per the CDC, more than a third of people who have a TIA and don’t get treatment have a major stroke within 1 year.
- Don’t let them sleep it off. Call 911 and note when symptoms started. MedlinePlus says tPA can only be given within 4 hours of when symptoms started.
Stroke Risk Factors and Prevention for DFW Adults
Many strokes can be prevented. The CDC lists the major risk factors, and most are within your control.
High blood pressure is a leading cause of stroke, per the CDC. Lowering it can also lower your risk. Diabetes, high cholesterol, atrial fibrillation, smoking, and obesity can also raise your risk.
Other factors add up too:
- Sleep apnea. Untreated sleep apnea increases the risk for stroke, per the NHLBI.
- Age over 55. The CDC says the chance of having a stroke about doubles every 10 years after age 55.
What helps: regular blood pressure checks, taking prescribed medications consistently, 2 hours and 30 minutes of moderate activity each week, and not smoking. Atrial fibrillation matters too. The CDC links it to an approximately fivefold increased risk of ischemic stroke.
What Happens When You Arrive at the ER of Irving for a Suspected Stroke
At the ER of Irving, the stroke pathway starts the moment paramedics call ahead. The American Heart Association notes that guidelines recommend giving tPA within 60 minutes of arrival. The goal is to compress every minute that matters. The team examines the patient and orders a brain scan to look for bleeding. That result guides the decision on tPA or transfer to a comprehensive stroke center.
Our 24/7 ER team is set up to keep the tPA window open. We coordinate with regional comprehensive stroke centers for cases that need endovascular thrombectomy or neurosurgery.
If you suspect a stroke, call 911 and tell them to bring the patient here.
FAQs
How long after symptoms start is tPA still effective?
MedlinePlus says tPA can only be given within 4 hours of when symptoms started. The sooner it is given, the better the chance of recovery. Some patients may also need endovascular thrombectomy, which removes a clot through a catheter.
Can young people have strokes?
Yes. Per the CDC, about one in seven strokes occur in adolescents and young adults ages 15 to 49. Experts link this to more young people having obesity, high blood pressure, and diabetes. Sudden severe headache or vision loss in a young adult should not be dismissed.
What does a mini-stroke feel like?
A transient ischemic attack, or TIA, produces stroke-like symptoms. Per MedlinePlus, most TIA symptoms disappear within an hour, although they may last for up to 24 hours. The damage to brain cells isn’t permanent, but a TIA raises your risk of stroke. The CDC says more than a third of people with an untreated TIA have a major stroke within 1 year. Get evaluated.
Can stress trigger a stroke?
Per the American Heart Association, chronic stress may lead to high blood pressure, which can increase the risk for stroke. The AHA says more research is needed on how stress contributes to stroke.
What is the difference between a heart attack and a stroke?
A heart attack is a blockage in a heart artery, usually causing chest pain. A stroke is a blockage or bleed in a brain artery, causing neurological symptoms like face droop or speech trouble. Both need 911.
What is the recovery time after a stroke?
It varies. Per MedlinePlus, problems moving, thinking, and talking often start to improve in the days to weeks after a stroke. Many people keep improving in the months or years after. How quickly treatment is given affects the outlook.
