How to Prevent a Second Stroke: Expert Tips and FAQs

Experiencing a stroke is a life-changing occurrence. But did you know that “nearly 1 in 4” strokes occur in people who have had a previous stroke?  Preventing a second stroke is not just an important precaution; it can be life-saving.

At Aviv Clinics, we provide practical, research-backed strategies to help reduce your risk of a recurring stroke and protect your long-term brain health. This FAQ guide answers many key questions about second strokes, from their symptoms and causes to prevention tips. Our goal is for you to take proactive steps toward a healthier, safer future.  If you have questions along the way, contact our team to discuss how the Aviv Medical Program may be able to help.

Are Strokes Recurring? Understanding the Risk of a Second Stroke

Yes, even after surviving a stroke, there’s a possibility of a recurrence. However, lifestyle changes and medical management can significantly lower the risk of having another stroke. The American Stroke Association notes, “up to 80% of strokes may be prevented with a combination of medication and healthy habits.” 

What Are the Chances of Having a Second Stroke? 

About 23% of stroke survivors experience a second stroke, according to Johns Hopkins Medicine: “…of the 795,000 Americans who will have a first stroke this year, 23 percent will suffer a second stroke.” 

Physicians note the risk of a second stroke is “highest within the first two days” after the first incident. Survivors remain at risk for “up to three months and even up to one year after the first stroke.” Other studies indicate that the odds of experiencing an adverse event (including another stroke, a heart attack, admission to long-term care, or death) are over 35% over the five years following a stroke.

What Causes a Second Stroke? 

The same factors that caused the first stroke can trigger a second stroke. For example, let’s look at the causes of an ischemic stroke.

These are the most common types of stroke, and “account for 87% of strokes in the United States.” Ischemic strokes occur when a blood vessel becomes blocked or narrowed, cutting off the blood supply to the brain. 

Risk factors for ischemic stroke include: 

• Hypertension
• Diabetes 
• Hyperlipidemia (high blood cholesterol)
• Sleep apnea
• Obesity 

Other risk factors linked to stroke entail: 

• Smoking
• Sedentary lifestyle
• Heart problems

The key is to identify the root cause(s) and speak with your doctor about lowering your risk. 

Is a Second Stroke Worse Than the First?

Yes, a second stroke is typically worse than the first due to the additional damage to the brain.

According to research, the second stroke carries “significant cognitive and physical disabilities” compared to the first stroke. 

Even those who have had a silent stroke are at risk for more adverse effects. It’s not uncommon to suffer several silent strokes before noticing a significant neurological change. 

How Many Brain Cells Die Every Second During a Stroke?

Researchers estimate that a person who has a stroke “loses 1.9 million neurons each minute” following the incident, making immediate treatment critical.

Time is of the essence upon a stroke.

Knowing the signs and symptoms of a possible stroke is crucial. 

What Are the Common Signs and Symptoms of a Second Stroke?

A helpful way to remember the signs and symptoms of a second stroke is the FAST acronym: 

• F: Facial drooping
• A: Arm weakness
• S: Speech difficulty
• T: Time to call 9-1-1 

Additional signs and symptoms of a second stroke include:

• Nausea
• Vertigo
• Confusion
• Visual changes

What Are the Chances of Surviving a Second Stroke?

Survival rates decrease with a second stroke. One study found that stroke survivors who have a second stroke are “2.67 times more likely to die” than stroke survivors who did not have a recurrence.

The second stroke inflicts additional damage to the brain, so it’s more challenging to overcome. But getting the proper support through the five stages of stroke security offers plenty of hope for second stroke survivors.

How Can You Prevent a Second Stroke? Lifestyle and Medical Strategies

You can help prevent a second stroke by making healthy lifestyle choices. Preventive strategies include regular exercise, a diet rich in fruits and vegetables, managing stress, adhering to prescribed medications, and considering therapies like hyperbaric oxygen therapy (HBOT) under medical guidance.

While there’s no way to guarantee that someone won’t experience a second stroke, these five prevention strategies can help minimize the most common risk factors. Please discuss prevention strategies with your physician first before making any lifestyle shifts. 

1. Incorporate a Regular Exercise Routine

Physiologists at Aviv Clinics recommend at least 30 minutes of physical activity three days a week. Exercise can help manage blood pressure, cholesterol, diabetes, and weight. Try doing an exercise activity you enjoy to help you stay motivated and committed. 

Physical performance is one of the key elements of the Aviv Medical Program. Our team of physiologists and physical therapists can conduct a thorough evaluation of your physical performance and prescribe a regimen of exercise and physiotherapy designed specifically for your needs and goals to continue recovery after a stroke.

2. Consume More Fruits and Vegetables 

Follow a diet rich in fruits and vegetables. These foods contain nutrients that may lower risk factors for stroke. 

Learn about the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet for more tips. It blends two types of diets: 

• Mediterranean diet: Foods that promote heart health
• DASH diet: Foods that help with hypertension (high blood pressure)

Nutrition is also a key element of the Aviv Medical Program. Based on your body composition and nutritional needs, your team of expert clinicians can advise you on the best diet to build a solid foundation for further recovery.

3. Find Coping Strategies for Stress

Stress is inevitable in life, and it’s crucial to find healthy ways to cope with it. 

Smoking or consuming alcohol “can raise blood pressure levels and the risk for stroke.” Discover better coping strategies for stress, like the following: 

• Practicing meditation
• Seeking therapy or counseling
• Engaging in new hobbies 

Aviv’s team of neuropsychological professionals can offer more guidance on improving sleep and reducing stress as part of the Aviv Medical Program.

4. Stay Consistent with Your Medication

Stick with your prescribed medication. It can lower your risk of having a secondary stroke. Studies report:

People with heart disease who took “75 percent or less of their medications as prescribed had a four times higher risk of stroke” than those who took their medicine as directed. 

5. Learn About Hyperbaric Oxygen Therapy (HBOT) 

Decades of research illustrate HBOT can lead to neurological improvements in post-stroke patients, even at chronic late stages. These findings offer hope for survivors who had a stroke months or years earlier. 

Aviv Clinics’ evidence-based HBOT protocol includes fluctuating between high and normal oxygen levels during multiple sessions over the course of twelve weeks. These fluctuations and additional therapeutic programs encourage the body to heal damaged brain tissue and create new blood vessels, improving the flow of blood and oxygen to the brain. Remember that restricted blood flow is one of the primary causes of strokes.
