Know the Warning Signs of a Stroke: A Guide for Lake Forest, Laguna Hills, Laguna Woods, Aliso Viejo, Irvine, Laguna Niguel, and Dana Point Residents

May is Stroke Awareness Month and if you live in South Orange County, this is information you need to share with your family, neighbors, and community.

Every 40 seconds, someone in the United States has a stroke. Every four minutes, someone dies from one. Whether you’re a longtime resident of Lake Forest, a retiree in Laguna Woods, a young professional in Irvine, or raising a family in Aliso Viejo, stroke does not discriminate by age, zip code, or lifestyle. The good news? Up to 80% of strokes are preventable — and recognizing the warning signs early can mean the difference between full recovery and permanent disability.

This month, we’re encouraging residents across Laguna Hills, Laguna Niguel, Dana Point, and surrounding South Orange County communities to learn, prepare, and share this life-saving information.

What Is a Stroke?

A stroke occurs when blood flow to the brain is suddenly interrupted — either by a blocked artery (ischemic stroke) or a burst blood vessel (hemorrhagic stroke). When the brain is deprived of oxygen, brain cells begin dying within minutes. That’s why rapid recognition and emergency response is absolutely critical.

For communities like Dana Point and Laguna Niguel where outdoor activity is part of daily life, and in retirement-active communities like Laguna Woods, understanding stroke risk is especially important. Many stroke risk factors increase with age — and South Orange County has one of the fastest-growing senior populations in California.

Recognize the Warning Signs: B.E. F.A.S.T.

Medical professionals use the B.E. F.A.S.T. acronym to help people identify a stroke quickly. If you or someone near you — whether you’re on the trails in Aliso Viejo, at a coffee shop in Lake Forest, or at the beach in Dana Point — shows any of these signs, call 911 immediately.

B — Balance A sudden and unexplained loss of balance or coordination. The person may stumble, veer to one side, or be unable to stand without support.

E — Eyes Sudden vision problems, including blurred vision, double vision, or loss of sight in one or both eyes.

F — Face Drooping Ask the person to smile. Does one side of their face droop? Is their smile uneven? Facial drooping on one side is a classic stroke warning sign.

A — Arm Weakness Ask the person to raise both arms. Does one arm drift downward? Is there sudden weakness or numbness in one arm or leg?

S — Speech Difficulty Is the person slurring their words? Are they speaking in a confused or jumbled way? Are they unable to speak at all or unable to repeat a simple sentence?

T — Time to Call 911 If you observe any of the above signs, call 911 immediately. Note the exact time the symptoms began — this information is critical for emergency medical teams and may determine which treatments are available.

Do not drive to the hospital yourself. Emergency responders can begin treatment en route. Residents in Irvine, Laguna Hills, and across South Orange County should always call 911 first.

Additional Stroke Warning Signs

Beyond B.E. F.A.S.T., be alert to these often-overlooked symptoms:

• Sudden, severe headache with no known cause — often described as the worst headache of one’s life
• Sudden confusion or difficulty understanding what others are saying
• Numbness on one side of the body, including the face, arm, or leg
• Sudden dizziness, loss of coordination, or trouble walking

Don’t Ignore a Mini-Stroke (TIA)

A transient ischemic attack — commonly called a TIA or “mini-stroke” — produces the same symptoms as a full stroke, but they resolve within minutes to hours. Many people in Laguna Hills, Lake Forest, and across Orange County dismiss TIAs because the symptoms seem to pass on their own.

This is a dangerous mistake. A TIA is a serious medical emergency and a major warning sign that a full stroke may follow within days. If you or a loved one experiences TIA symptoms, call 911 — even if you feel fine by the time help arrives.

How to Prevent a Stroke: Steps Every South Orange County Resident Can Take

Stroke prevention starts with lifestyle. Whether you’re walking the trails in Aliso Viejo, cycling along the coast in Dana Point, or hitting the gym in Irvine, daily habits have a measurable impact on your stroke risk.

1. Control Your Blood Pressure

High blood pressure — or hypertension — is the single most significant risk factor for stroke. Many people don’t know their blood pressure is elevated because it has no symptoms. Regular checkups with a primary care physician in your area — whether in Laguna Niguel, Lake Forest, or Irvine — are the first step to knowing your numbers. Aim for a reading below 120/80 mmHg.

2. Quit Smoking

Smoking significantly increases the risk of blood clots and narrows the arteries that supply blood to the brain. The risk of stroke begins to drop within weeks of quitting, and continues to decline over time. If you’re a smoker in Laguna Hills, Dana Point, or anywhere in South Orange County, talk to your doctor about cessation programs and resources available to you.

3. Manage Blood Sugar and Cholesterol

Diabetes and high LDL cholesterol both damage blood vessel walls over time, making strokes more likely. Routine blood work — available at clinics throughout Irvine, Laguna Niguel, and Lake Forest — can detect these conditions early, often before symptoms appear.

4. Stay Physically Active

South Orange County is a paradise for outdoor activity — from hiking the Aliso and Wood Canyons in Aliso Viejo and Laguna Hills to swimming and paddleboarding in Dana Point Harbor. Aim for at least 150 minutes of moderate-intensity exercise each week. Regular physical activity lowers blood pressure, helps maintain a healthy weight, and reduces inflammation — all of which lower stroke risk.

5. Eat a Heart-Healthy Diet

A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats can significantly reduce stroke risk. Limit your intake of sodium, saturated fats, and ultra-processed foods. Farmers markets throughout Laguna Hills, Lake Forest, and Irvine make it easy to find fresh, whole foods year-round.

6. Limit Alcohol Consumption

Heavy drinking raises blood pressure and increases stroke risk. If you drink alcohol, limit consumption to no more than one drink per day for women and two for men.

7. Know and Treat Atrial Fibrillation (AFib)

Atrial fibrillation is an irregular heart rhythm that increases the risk of blood clots forming in the heart — clots that can travel to the brain and cause a stroke. AFib is more common in adults over 65, which is especially relevant for the large and active senior community in Laguna Woods. If you have been diagnosed with AFib, following your treatment plan is one of the most important things you can do to prevent stroke.

Who Is Most at Risk?

Understanding your personal risk profile is key to prevention. Stroke risk factors fall into two categories:

Controllable risk factors (can be reduced or eliminated):

• High blood pressure
• Smoking
• Obesity
• Physical inactivity
• Diabetes
• High cholesterol
• Heavy alcohol use
• Untreated AFib

Uncontrollable risk factors (cannot be changed, but should be known):

• Age — risk increases significantly after age 55
• Family history of stroke
• Prior TIA or stroke
• Being of African American, Hispanic, or Asian descent (higher statistical risk)

If you have multiple uncontrollable risk factors, it’s even more important to aggressively manage the ones you can control. Talk to a healthcare provider in Irvine, Lake Forest, Laguna Niguel, or your nearest South Orange County community.
