Dravet syndrome: From neurodevelopmental to neurodegenerative disease?

Abstract

This is the largest group of adults with DS to be systematically evaluated. They had severe nonseizure symptoms. Older age and longer use of SCBs were associated with worse adaptive skills, gait, and parkinsonism. Some older adults screened positive for depression and dementia. Caregivers identified functional decline in activities of daily living (ADLs). Taken together, the risk of dementia, parkinsonian gait, and decline in ability to perform previously mastered ADLs support that some adults with DS may be developing a neurodegenerative disorder.
