Dravet syndrome is a terrible disease generally caused by mutations of the SCN1A gene. Recently others genes such as STXBP1 have been involved in the pathogenesis of the disease. The STXBP1 mutation in patients with Dravet Syndrome may additionally causes several parkinsonian features usually attributed to carriers of the SCN1A mutation. Management continues to be difficult that is why Cannabidiol emerged as valid option for treatment of this condition.
