0

Unlikely, below 8

Band: Unlikely, below 8

Interpretation. Unlikely, below 8

Suggested management. A total below 8 is unlikely Lennox-Gastaut syndrome in the weighted screen.

REST-LGS Weighted Screen: 0 — Unlikely, below 8. Interpretation: Unlikely, below 8 What to do: A total below 8 is unlikely Lennox-Gastaut syndrome in the weighted screen. Inputs: Two or more seizure types: false; Seizure onset before 12 years: false; Slow spike-and-wave under 2.5 Hz: false; Cognitive impairment since childhood: false; Seizures despite at least two medicines: false; Vagus-nerve stimulation, ketogenic diet, or epilepsy surgery: false; Helmet use or head or face injury from seizures: false; Other EEG abnormalities: false Source: Wolf SM et al. Real-world use of the updated refractory epilepsy screening tool for Lennox-Gastaut syndrome. Epilepsia Open. DOI: 10.1002/epi4.12952. PMID: 38726917. Each of four major criteria scores 3: two or more seizure types, seizure onset before 12 years, slow spike-and-wave under 2.5 Hz, and cognitive impairment since childhood. Each of four minor criteria scores 1: seizures despite at least two antiseizure medicines; vagus-nerve stimulation, a ketogenic diet, or epilepsy surgery; seizure-related helmet use or head or face injury; and other EEG abnormalities (multifocal spikes, symptomatic generalized discharges, attenuation or electrodecrement, or paroxysmal fast activity). Likely is above 11, possible is 8 through 11, and unlikely is below 8. (2024)
