“Marijuana-based treatment for refractory epilepsy shows promise in surveys, case series and clinical trials.

However, literature on their electroencephalography (EEG) effects is sparse.

Our objective is to analyze the effect of marijuana on EEG in a 24-year-old patient with idiopathic generalized epilepsy (IGE) treated with cannabis.

Using a novel approach to electroencephalographic data, we demonstrate a decrease in interictal and ictal electrographic events during marijuana use.

Larger samples of patients and EEG, with standardized cannabinoid formulation and dosing are needed to validate our findings.”
