(Knupp, et al. 2017) This online survey of 202 caregivers measured frequencies of reported comorbidities commonly associated with Dravet syndrome. 99% of caregivers reported an issue with appetite, 82% reported sleep concerns, 75% reported falls and balance concerns, and 69% reported significant concerns with the patient’s attention. Detailed analysis showed that most concerns outpaced the concerns reported by caregivers of neurotypical patients, and that Dravet syndrome affects multiple body systems.
