Adult Epilepsy: Seizure Severity

Seizure Severity in Medically Treated Adult Epilepsy Patients (N = 6874)

2008 – 2018

The effect of medical treatment on seizure severity was assessed using the Liverpool Seizure Severity Scale (LSSS), a validated patient-completed questionnaire developed to quantify seizure severity. Of the 6874 patients seen from 2008 through 2018, 35.3% improved, 49.6% remained stable, and 15.1% had a worsening in seizure severity. Clinically meaningful change was defined as a total point change of ≥ 5.1
