ABSTRACT
OBJECTIVE: To increase understanding of the impact of cannabidiol (CBD) on outcomes beyond seizure control among individuals with Dravet syndrome or Lennox-Gastaut syndrome. METHODS: Qualitative interviews were conducted with caregivers of individuals with Dravet syndrome or Lennox-Gastaut syndrome treated with plant-derived, highly purified CBD medicine (Epidiolex in the USA; Epidyolex in Europe; 100â mg/mL oral solution). Symptoms and impacts of Dravet syndrome and Lennox-Gastaut syndrome on individuals were explored, as were the effects of CBD. Data were analyzed using thematic analysis. RESULTS: Twenty-one caregivers of individuals with Dravet syndrome (n = 14) and Lennox-Gastaut syndrome (n = 7) aged 4-22 years participated. Health-related quality of life improvements associated with CBD included cognitive function, communication, behavior, mobility, and participation in daily activities. Seizure frequency reduction was commonly reported (n = 12), resulting in caregivers having greater freedom and family life being less disrupted. Adverse events were reported by 10 caregivers. CONCLUSION: In addition to reduced seizure frequency, CBD may have a wide range of beneficial effects beyond seizure control that warrant further investigation.
