Dravet Syndrome Severity Score

Assess Dravet syndrome severity based on seizure frequency, prolonged seizure episodes, developmental trajectory, and SCN1A mutation status.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Assess Dravet syndrome severity based on seizure frequency, prolonged seizure episodes, developmental trajectory, and SCN1A mutation status

Each component has a specific meaning:

  • Seizure frequency — The seizure frequency recorded for the scenario being assessed.
  • Prolonged seizure episodes — The prolonged seizure episodes recorded for the scenario being assessed.
  • Developmental trajectory — The developmental trajectory recorded for the scenario being assessed.
  • SCN1A mutation status — The scn1a mutation status recorded for the scenario being assessed.

Note: Interpret the dravet severity result against the thresholds and context described above.

How to Use

Enter the seizure frequency, prolonged seizure episodes, developmental trajectory, SCN1A mutation status for the scenario you are assessing. Assess Dravet syndrome severity based on seizure frequency, prolonged seizure episodes, developmental trajectory, and SCN1A mutation status. Use the dravet severity result to inform your calculation.
