This guide outlines evidence-based strategies to reduce the incidence of cerebrovascular events. It is essential to consult with your doctor before making significant changes to your medical regimen or starting new treatments.
High blood pressure (hypertension) remains the leading modifiable cause of stroke globally. When blood pressure is consistently high, it weakens the blood vessels in the brain. Other cardiovascular (CV) risk factors, such as diabetes and obesity, compound this damage.
Goal: Aim for blood pressure below 120/80 mmHg where clinically appropriate.
Action: Regularly monitor your levels at home or in a clinic; and work with a doctor to manage glucose and salt intake.
Atrial fibrillation (AF) is an irregular heart rhythm that can cause blood to pool and form clots in the heart. If these clots travel to the brain, they cause an embolic stroke.
The Risk: AF is estimated to increase stroke risk approximately fivefold.
Action: Seek a medical review if you experience palpitations, unexplained breathlessness, or an irregular pulse. Anticoagulants (blood thinners) are often prescribed to significantly reduce the risk of clot formation.
Excess LDL (“bad”) cholesterol contributes to atherosclerosis, a condition where plaque builds up and narrows the arteries. This narrowing can eventually block blood flow to the brain or cause a clot to rupture.
Goal: Maintain low LDL levels and preserve the elasticity of your blood vessels.
Action: Incorporate heart-healthy fats into your diet and, if recommended by a specialist, utilize statins or other lipid-lowering medications to manage your profile.
For individuals who have already experienced a stroke or a Transient Ischaemic Attack (TIA), the risk of a recurrence is significantly higher. Secondary prevention focuses on intensive management to ensure a second event does not occur.
Goal: Prevent recurrence through aggressive risk factor modification.
Action: Adhere to antiplatelet (e.g. aspirin and/or clopidogrel) or anticoagulant therapies and maintain stricter targets for blood pressure and cholesterol through specialist follow-up care.
Lifestyle choices form the foundation of vascular health. Small, consistent changes in daily habits can have a profound impact on the structural integrity of your circulatory system.
Focus: Emphasise a Mediterranean-style diet, consistent physical activity, and the elimination of tobacco products.
Action: Increase consumption of leafy greens, whole grains, and olive oil; aim for 150 minutes of moderate exercise weekly; and strictly limit alcohol intake.
The following table summarises the primary categories of stroke prevention and the necessary actions for each.
| Category | Prevention Strategy | Key Action Item |
| Medical | Blood Pressure Control | Aim for <120/80 mmHg; reduce salt |
| Medical | Manage Heart Rhythm | Screen for AF; use anticoagulants |
| Medical | Cholesterol Management | Lower LDL with diet or statins |
| Medical | Secondary Prevention | Antiplatelets; specialist follow-up |
| Lifestyle | Healthy Lifestyle | Mediterranean diet; 150 min exercise |
Even with the best prevention strategies, it is vital to recognize the signs of a stroke immediately. Early intervention is the most critical factor in recovery and survival.
Balance: Sudden loss of balance or coordination.
Eyes: Sudden vision changes or loss of sight.
Face: One side of the face drooping when smiling.
Arms: Weakness or drifting downward when both arms are raised.
Speech: Slurred, strange, or confused speech.
Time: If any of these signs are present, call emergency services immediately.
