1. What is a Stroke Risk Calculator?

Definition: This calculator estimates an individual's risk of stroke based on common risk factors.

Purpose: It helps identify individuals who may benefit from preventive measures or medical intervention.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Stroke risk score (dimensionless)
• \( W_i \) — Weight of risk factor i (dimensionless)
• \( F_i \) — Presence of risk factor i (dimensionless)

Explanation: Each selected risk factor contributes to the total score based on its relative importance.

3. Importance of Stroke Risk Assessment

Details: Early identification of stroke risk allows for timely intervention and preventive measures.

4. Using the Calculator

Tips: Check all risk factors that apply. The calculator will sum the weighted values to determine your risk score.

5. Frequently Asked Questions (FAQ)

Q1: What do the different scores mean?
A: Scores ≥7 indicate high risk, 4-6 moderate risk, and ≤3 low risk.

Q2: Are all risk factors equally important?
A: No, factors like atrial fibrillation carry more weight than others.

Q3: Is this a diagnostic tool?
A: No, it's a screening tool. Always consult a doctor for proper evaluation.

Q4: What's not included in this calculator?
A: Family history, age, and other factors may also influence stroke risk.

Q5: How often should I check my stroke risk?
