According to the World Stroke Organization, 101 million people were living who have experienced a stroke in 2019, with the 15-49 years age group accounting for 22% of them. Stroke remains a leading cause of death and disability globally, highlighting its substantial impact on public health. Furthermore, the American Stroke Association reports that someone in the United States has a stroke every 40 seconds, making it the fifth leading cause of death in the country.
Stroke risk factors include smoking (2-4 times increased risk), excessive alcohol, poor diet, and inactivity. Medical conditions like hypertension (50% of strokes), diabetes, and atrial fibrillation also elevate risk. Age doubles risk each decade after 55.

Understanding the Risk for Stroke; Identifying the Symptoms
A stroke, medically referred to as a cerebrovascular accident (CVA), is a critical medical condition that occurs when the blood supply to a part of the brain is interrupted or reduced. This interruption deprives brain tissue of essential oxygen and nutrients, leading to the rapid death of brain cells. Strokes are a medical emergency and require immediate medical attention to minimize brain damage and potential long-term disability. There are primarily two types of strokes:
Ischemic Stroke
This is the most common type of stroke, accounting for approximately 85% of all cases. It occurs when a blood vessel supplying blood to the brain is obstructed or blocked by a blood clot. There are two subtypes:
- Thrombotic Stroke: Caused by a clot (thrombus) forming within one of the brain’s arteries.
- Embolic Stroke: Caused by a clot or debris that forms elsewhere in the body (often the heart) and travels to the brain.
Hemorrhagic Stroke
This type of stroke occurs when a blood vessel in the brain ruptures or leaks.
The two main types of hemorrhagic stroke are:
- Intracerebral Hemorrhage: Occurs when a blood vessel within the brain ruptures, causing bleeding within the brain tissue.
- Subarachnoid Hemorrhage: Occurs when there is bleeding in the space between the brain and the surrounding membrane.
Transient Ischemic Attack (TIA)
- Often referred to as a “mini-stroke,” a TIA is a temporary blockage of blood flow to the brain.
- It does not cause permanent damage, but it is a warning sign that a more severe stroke may occur in the future and should be taken seriously.
Symptoms of Stroke
The acronym “FAST” is commonly used to recognize and respond to the signs of a stroke:
- F – Face Drooping: One side of the face droops or feels numb.
- A-Arm Weakness: One arm drifts downward when raised.
- S – Speech Difficulty: Speech is slurred, or the person is unable to speak or understand.
- T – Time to Call Emergency Services: If any of these symptoms are observed, it is crucial to seek immediate medical attention.
Other common symptoms include sudden numbness or weakness in the face, arm, or leg, especially on one side of the body; sudden confusion, trouble speaking, or understanding speech; sudden trouble seeing in one or both eyes; sudden trouble walking, dizziness, loss of balance, or coordination; and sudden severe headache with no known cause.
Stroke is a leading cause of death and disability globally, with over 12 million people experiencing a stroke each year. Of these, millions suffer long-term disability, and a significant portion die from the stroke. World Health Organisation
Early Recognition of Stroke Symptoms: Essential for Minimizing Impact
Early detection of stroke risk is crucial for prevention and timely intervention, which can significantly reduce the likelihood and severity of a stroke. It allows for the implementation of effective lifestyle modifications, medication, and regular medical check-ups to manage risk factors effectively. Early awareness also empowers individuals to recognize stroke symptoms promptly using the “BE FAST” acronym, facilitating timely emergency medical care and optimizing recovery outcomes by minimizing brain damage and reducing long-term disability. Use our Risk for Stroke Assessment to identify the symptoms early. Also, explore our Panic Attack Assessment for more guidance!

| Time to Treatment | Improvement in Outcomes (%) |
|---|---|
| Within 1 Hour | 35-45% |
| Within 2 Hours | 40-50% |
| Within 3 Hours | 40-50% |
| Within 4 Hours | 35-45% |
| Within 4.5 Hours | 30% |
| Within 6 Hours | 25% |
| Within 12 Hours | 20% |
| Within 24 Hours | 15-20% |
Key Factors Contributing to Risk for Stroke
Medical Conditions
- Hypertension (High Blood Pressure): Elevated blood pressure damages blood vessels, increasing the risk of blockages or ruptures.
- Diabetes: This condition can damage blood vessels and elevate the risk of atherosclerosis, leading to stroke.
- Atrial Fibrillation (AFib): AFib is an irregular heart rhythm that can cause blood clots, which may travel to the brain and cause a stroke.
Lifestyle Choices
- Smoking: Tobacco use damages blood vessels and promotes the formation of blood clots, increasing stroke risk.
- Excessive Alcohol Consumption: Heavy drinking can raise blood pressure, contribute to heart disease, and increase the risk of stroke.
- Physical Inactivity: Lack of regular exercise can lead to obesity, high blood pressure, and other risk factors for stroke.
- Unhealthy Diet: A diet high in saturated fats, trans fats, and salt can contribute to atherosclerosis and hypertension, increasing the risk of stroke.
Biological Factors
- High Cholesterol Levels: Elevated levels of LDL cholesterol (bad cholesterol) can lead to the buildup of plaque in the arteries, increasing the risk of stroke.
Age
- The risk of stroke increases with age, with the majority of strokes occurring in people over 65.
Gender
- Men have a slightly higher risk of stroke than women, but women are more likely to die from a stroke.
Ethnicity
- African Americans, Hispanics, and Asian/Pacific Islanders have a higher risk of stroke compared to Caucasians.
Family and Personal History
- Having a close family member who has had a stroke increases the risk.
Previous Stroke or Transient Ischemic Attack (TIA)
- Having had a stroke or TIA in the past increases the risk of experiencing another stroke.

Effective Strategies to Prevent the Risks of Stroke
Here are effective strategies to prevent the risk factors associated with stroke:
- Control Blood Pressure: Monitor and maintain blood pressure within the normal range through a healthy diet, regular exercise, and limiting alcohol intake.
- Manage Diabetes: Monitor blood sugar levels and manage them through a balanced diet, regular exercise, and prescribed medication.
- Maintain a Healthy Weight: Adopt a balanced diet low in saturated fats and sugars and engage in regular physical activity.
- Quit Smoking: Seek support from smoking cessation programs and avoid exposure to secondhand smoke.
- Manage Atrial Fibrillation (AFib): Regularly consult with a healthcare professional to monitor and manage AFib, and adhere to prescribed medications.
- Control Cholesterol Levels: Follow a diet low in saturated fats and cholesterol, engage in regular exercise, and consult with a healthcare professional about cholesterol-lowering medications if necessary.
- Limit Alcohol Consumption: Limit alcohol intake to moderate levels and avoid binge drinking.
- Eat a Healthy Diet: Consider following the DASH (Dietary Approaches to Stop Hypertension) diet, which is rich in fruits, vegetables, and low-fat dairy products.
- Regular Physical Activity: Engage in moderate-intensity aerobic exercise, such as brisk walking, for at least 150 minutes per week, and incorporate strength training exercises at least two days per week.
- Seek Prompt Medical Attention: Familiarize yourself with the BE FAST acronym (Balance problems, Eyesight changes, Facial drooping, Arm weakness, Speech difficulty, Time to call emergency services) to recognize stroke symptoms and seek immediate medical attention if they occur.
Implementing these strategies can significantly reduce the risk of stroke and improve overall cardiovascular health.
The overall death rate for stroke increased from 38.8 per 100,000 in 2020 to 41.1 per 100,000 in 2021. CDC
