A stroke occurs when blood flow to the brain is interrupted or significantly reduced, depriving brain cells of oxygen and nutrients, which can lead to cell death. Each year, approximately 800,000 individuals worldwide experience strokes, equivalent to about one person every forty seconds. Prompt identification and treatment of strokes are critical to minimizing brain damage. This article will explore the causes, management, and prevention of strokes, emphasizing the expertise of the best neurologist, Dr. Manoj Khanal, who is renowned for providing the best stroke treatment.
Categories of Stroke
Strokes are classified into three primary categories:
- Ischaemic Stroke: The most common type of stroke occurs when a blood clot obstructs the brain’s blood supply, preventing it from receiving blood and oxygen.
- Hemorrhagic Stroke: This type of stroke results from the rupture of a weakened blood vessel, often caused by aneurysms or arteriovenous malformations (AVMs).
- Transient Ischaemic Attack (TIA): Also known as a mini-stroke, this occurs when blood flow to a part of the brain is temporarily blocked. Symptoms usually resolve quickly as normal blood flow is restored.
Risk Factors and Prevention
While age and family history of stroke are non-modifiable risk factors, you can still reduce your stroke risk by adopting certain preventive measures:
- Regular Exercise: Inactivity is linked to numerous health issues, including stroke. Regular exercise helps lower other stroke risk factors such as obesity and high blood pressure. The American Stroke Association recommends 40 minutes of moderate to high-intensity aerobic exercise, three to four times a week, to keep your heart healthy and reduce stroke risk.
- Healthy Diet: A balanced diet can help lower blood pressure, a major risk factor for stroke. Avoiding excessive sodium and ensuring sufficient potassium intake are essential. Consuming potassium-rich fruits and vegetables, whole grains, low-fat dairy, and low saturated fats can prevent stroke.
- Manage Hypertension: High blood pressure is a leading risk factor for both hemorrhagic and ischaemic strokes. Maintaining a healthy weight, engaging in physical activity, and following a low-sodium diet can keep blood pressure in check. It’s important to have your blood pressure checked regularly, at least once a year.
- Lower Cholesterol: High total cholesterol levels increase stroke risk. A diet rich in fruits, vegetables, whole grains, and lean proteins, combined with statins if necessary, can help reduce cholesterol and prevent arterial blockage. Discuss with your doctor if statins are appropriate for you.
- Quit Smoking: Smoking significantly raises the risk of stroke. Quitting smoking, even after years of the habit, can dramatically reduce stroke risk.
- Medication Adherence: For those at high risk of stroke, taking anticoagulant medications like aspirin or warfarin under medical guidance can prevent blood clots and protect cardiovascular health.
