Salzburg Criteria for Nonconvulsive Status Epilepticus
Salzburg consensus criteria for nonconvulsive status epilepticus (Leitinger 2015).
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- EEG pattern
- Epileptiform discharges <= 2.5/s OR rhythmic delta/theta > 0.5/s
- Spatiotemporal evolution
- Yes
- Subtle clinical ictal phenomena
- No
- Clinical and EEG improvement after IV antiseizure medication
- No
- EEG-only improvement after IV antiseizure medication
- No
Result: Salzburg criteria: Definite NCSE (pattern plus a secondary criterion).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Definite
- Discharges > 2.5/s, or a slower pattern with a secondary criterion.
- Possible
- EEG-only improvement after IV antiepileptic. A diagnostic classification, not a treatment order.
What you enter
- EEG pattern (worst 10-second epoch)
- Spatiotemporal evolution
- Subtle clinical ictal phenomena
- Clinical and EEG improvement after IV antiseizure medication
- EEG-only improvement after IV antiseizure medication
