Stroke Risk Factors: A Complete Guide to Understanding Your Personal Risk

Stroke is a leading cause of disability and death worldwide. Knowing your risk factors empowers prevention.

Modifiable Risk Factors

• High blood pressure (hypertension): #1 risk factor—damages vessel walls.
• High LDL cholesterol: Drives atherosclerotic plaque buildup.
• Diabetes: High glucose damages vessels and nerves.
• Smoking: Damages endothelium, promotes clotting.
• Obesity: Linked to hypertension, diabetes, dyslipidemia.
• Physical inactivity: Contributes to above risks.
• Excessive alcohol: Raises BP, triggers arrhythmias.
• Atrial fibrillation (AFib): 5x stroke risk due to clot formation.
• Sleep apnea: Intermittent hypoxia strains cardiovascular system.

Non-Modifiable Risk Factors

• Age: Risk doubles each decade after 55.
• Sex: Men have higher incidence; women's risk rises after menopause.
• Race/ethnicity: Black and Hispanic adults face higher risk.
• Family history: Genetic predisposition.
• Prior stroke/TIA: Strongest predictor of recurrence.

Emerging/Other Factors

• Migraine with aura
• Chronic kidney disease
• Autoimmune conditions (lupus, antiphospholipid syndrome)
• Air pollution
