Dravet syndrome (DS) belongs to a set of rare, complicated epilepsies known as the developmental and epileptic encephalopathies. Presenting early in life in previously well and developmentally normal infants, DS results in neurocognitive and neurobehavioral impairment, reflected in a slowing or regression of a child’s development, behavior, or cognition. ‘Fast Facts: Dravet Syndrome’ offers a concise yet comprehensive review of this complex disease. It aims to provide all members of the multidisciplinary team with an overview of the current understanding of its pathophysiology and approaches to treatment, as well as an insight into future directions, thus supporting them in meeting the unique needs of individuals with DS.
