Stroke Awareness: Educating Patients To Save Lives

Stroke is a catastrophic event that can have pervasive effects on the lives of survivors and their families. It is the third leading cause of death and the major cause of long-term disability among older adults in the United States. As such, it is crucial for patients and their families to be educated about stroke, its warning signs, risk factors, and lifestyle changes that can help prevent it. Recognizing a stroke is the first step in getting the right treatment, and understanding risk factors can help reduce the chances of having a stroke. Additionally, stroke survivors may experience significant impairments and limitations after returning home, so continuing and targeted education is essential to help them manage their condition and improve their quality of life.

Recognising the signs of a stroke

Face Drooping

Ask the person to smile and observe if one side of their face droops or feels numb. This could be a sign of muscle weakness or paralysis, often occurring on just one side of the body.

Arm Weakness

Instruct the person to raise both arms. If one arm drifts or drops downward, it could indicate a stroke, as it suggests weakness or numbness in one arm.

Speech Difficulty

Listen to the person's speech. Slurred or strange speech, or difficulty in choosing the right words, could be a sign of a stroke, as it indicates potential issues with the brain's language centres.

Time to Call for Help

If you observe any of the above signs, it's time to act quickly. Call the emergency services (e.g. 911 in the US or 999 in the UK) immediately. Note the time when the first symptoms appeared, as this information is crucial for the medical team.

In addition to the FAST (Face, Arms, Speech, Time) test, there are other signs and symptoms that may indicate a stroke:

Numbness or weakness, especially on one side of the body
Blurred vision or loss of sight in one or both eyes
Confusion, disorientation, or memory loss
Dizziness, loss of balance, or lack of coordination
Severe headache with no apparent cause
Clumsiness or poor coordination
Loss or dimming of senses, including smell and taste

Remember, the signs of a stroke can appear suddenly and may vary between individuals. It's important to act FAST and seek immediate medical attention if you or someone you know exhibits any of these symptoms.

Understanding the urgency of treatment

Stroke is a medical emergency and early intervention is crucial to limiting brain damage. Treatments can reduce or completely reverse brain injury, but only if they are given within the first few hours of a stroke occurring.

The urgency of stroke treatment is often poorly appreciated by the public. This is reflected in the fact that many patients do not receive treatment within the necessary time frame. The short time window for treatment is one of the reasons why so few patients currently receive therapy.

The longer the delay in treating a stroke, the greater the risk of permanent brain damage and serious, long-term disability. The first few hours after a stroke are critical for effective reperfusion, with earlier restoration leading to greater tissue salvage.

The concept that "time is brain" underlines the importance of recognising the signs of stroke and seeking emergency treatment as soon as possible.

Knowing how to prevent strokes

Maintain a Healthy Weight

Obesity increases the likelihood of a stroke, as it often brings other risk factors such as high blood pressure, high cholesterol, and diabetes. Losing weight can significantly lower your chances of having a stroke. Work with your doctor to set realistic weight loss goals and develop a personalized strategy. Eating a balanced diet and increasing physical activity can help you achieve and maintain a healthy weight.

Control Your Blood Pressure

High blood pressure is the leading cause of strokes and significantly increases your risk. It often has no signs or symptoms, so regular monitoring is crucial. Work with your healthcare provider to determine your target blood pressure and develop a plan to achieve it. This may include lifestyle changes, such as reducing salt and high-cholesterol food intake, increasing fruit and vegetable consumption, and getting more exercise. If needed, your doctor may also prescribe blood pressure medication.

Manage Your Cholesterol

High cholesterol can raise your risk of stroke by contributing to plaque buildup in your arteries. Get your cholesterol levels checked regularly and work with your doctor to develop a plan to lower them if they are high. This may include dietary changes, such as adopting a DASH or Mediterranean diet, which emphasize fruits, vegetables, whole grains, fish, and nuts, while reducing saturated and trans fats.

Quit Smoking

Smoking is a significant risk factor for stroke, damaging the brain and blood vessels. Quitting smoking is one of the most effective ways to reduce your risk. Seek advice from your doctor and utilize quit-smoking aids, such as nicotine replacement therapy or counseling, to support your journey. Remember that it may take multiple attempts to quit successfully, so don't give up!

Treat Atrial Fibrillation

Atrial fibrillation, an irregular heartbeat, increases your stroke risk by causing clots to form in the heart, which can travel to the brain. If you experience symptoms like heart palpitations or shortness of breath, consult your doctor for an examination. Treatment options may include anticoagulant drugs (blood thinners) to reduce the risk of clotting and stroke.

Manage Your Blood Sugar

High blood sugar can damage blood vessels over time, making clot formation more likely. Monitor your blood sugar levels regularly and work with your healthcare team to keep them within a healthy range. This may involve dietary changes, exercise, and medication.

In addition to these key points, remember that regular exercise, moderate alcohol consumption, and stress management are also essential components of stroke prevention. By addressing these risk factors and adopting a healthier lifestyle, you can significantly reduce your chances of having a stroke.

Hypertension

Hypertension is the most important modifiable risk factor for stroke. The incidence of stroke increases proportionally with both systolic and diastolic pressure, increasing the relative risk by 3.1-fold for men and 2.9-fold for women. The risk of stroke in the setting of hypertension is also far-reaching. Hypertension is a primary driver of cerebral small vessel disease (CSVD) that leads to cognitive decline and lacunar stroke.

Diabetes

Diabetes greatly increases the risk of ischemic stroke. Diabetes causes plaque to build up in the arteries at a faster rate. People also tend to gain weight with diabetes, which can lead to high blood pressure and high cholesterol, both risk factors for stroke. When sugar (glucose) levels are high, damage from a stroke can be even worse. Good control of diabetes can reduce your risk of stroke.

Congestive heart failure

Congestive heart failure is a weakening of the heart muscle. The heart becomes less able to pump the amount of blood the body needs to perform normal activities. Congestive heart failure is a risk factor for stroke and getting treatment for this condition helps reduce the risk of stroke.

High cholesterol

Unhealthy cholesterol may lead to fat deposits in the arteries. These fat deposits are called plaque. Plaque narrows the arteries and can lead to stroke. To reach your cholesterol goals, you may need diet, exercise, and medicine. It is very important to work very hard to control your cholesterol to prevent a stroke or recurrent stroke. Eat a diet full of vegetables, lean meats, whole grains, and fruits. Exercise at least 30 minutes a day, for at least three days per week, to strengthen your heart and reduce your risk of building up cholesterol in your blood vessels.

Coronary heart disease

Coronary heart disease (CHD) shares common risk factors with stroke, such as age, sex, hypertension, smoking, metabolic syndrome, physical inactivity, and diet and nutrition. With increasing age, the accumulation of these systemic risk factors may further increase the possibility of developing a stroke.

Previous stroke

Previous stroke was reported as an independent predictor of long-term survival in stroke patients. Approximately three-fourths of strokes in the US are recurrent strokes. After an initial stroke, the risk of recurrence or death was also high among the Chinese population, with more than 40% experiencing a recurrent stroke within 5 years.

Other comorbidities

Other comorbidities that increase the risk of stroke include hyperlipidemia, chronic obstructive pulmonary disease, nephropathy, and cancer.

Rehabilitation and recovery

Stroke rehabilitation, or "rehab", is a crucial aspect of recovery, aiming to help patients regain independence and improve their quality of life. The rehab process involves a multidisciplinary team, including doctors, therapists, and social workers, who work together with the patient and their family. The program is tailored to the patient's specific needs, addressing physical, emotional, and cognitive impairments caused by the stroke.

Rehab programs focus on various aspects, such as treating the underlying disease, improving function, providing adaptive tools, and teaching patients and families how to adapt to lifestyle changes. This may include relearning self-care skills, improving communication and cognitive abilities, and addressing emotional disturbances. The extent and goals of rehab depend on factors like stroke severity, the patient's overall health, and available support systems.

The involvement of patients in decision-making during rehab is essential. Studies have shown that when patients are engaged in shared decision-making and goal-setting, it leads to greater satisfaction and improved functioning. Additionally, patient education is a continuous journey during stroke recovery. Educational programs can empower patients and caregivers by providing knowledge about secondary prevention, stroke signs, risk factors, and maintaining functional independence.

Rehab services are provided in various settings, including acute care hospitals, long-term care facilities, outpatient rehab centres, and even in patients' homes. The choice of a rehab facility should consider factors such as insurance coverage, location, qualifications of the facility and staff, availability of daily therapy, and the support provided to patients and families.
