Cannabidiol reduces atypical absence seizures and epileptic spasms in a Gabrb3+/D120N mouse model of Lennox–Gastaut syndrome

open access: yesEpilepsia Open, Volume 11, Issue 4, Page 1263-1275, August 2026.
Abstract Objective Lennox–Gastaut syndrome (LGS) is a drug‐resistant developmental and epileptic encephalopathy (DEE). Preclinical drug development for LGS is constrained by a lack of syndrome‐relevant animal models. We aimed to evaluate a Gabrb3+/D120N knock‐in (KI) mouse model of LGS by quantifying atypical absence seizures and epileptic spasms and ...
