What it calculates

The “ABCD2 Score” calculator computes ABCD2 total score from 6 parameters: age (years), systolic bp (mmHg), diastolic bp (mmHg), clinical features (0 other, 1 speech, 2 weakness), symptom duration (min), diabetes mellitus (1 = yes).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Age = 65 years, Systolic BP = 150 mmHg, Diastolic BP = 85 mmHg, Clinical features (0 other, 1 speech, 2 weakness) = 2, Symptom duration = 30 min, Diabetes mellitus (1 = yes) = 0 the result is 5 (Clinical features: 2 — unilateral weakness, 1 — speech disturbance without weakness, 0 — other).

How to use

  1. Enter age, systolic bp, diastolic bp, clinical features (0 other, 1 speech, 2 weakness), symptom duration and diabetes mellitus (1 = yes) — each field above is adjustable with a slider.
  2. ABCD2 total score is calculated automatically as you type.
  3. Check the worked example below to see the formula applied to real numbers.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
