It's great you're looking into the latest research! For Dravet syndrome, there's promising news regarding zorevunersen, a gene-regulation therapy. Early clinical trials show it may reduce seizures and improve cognition, behavior, and motor skills. You can check your child's eligibility for the Phase 3 Emperor study here: https://www.emperorstudy.com/

Also, be aware that behavioral and social issues can emerge early in Dravet syndrome, so early screening and intervention are key.

Unfortunately, I don't have specific Rett syndrome updates tied to autism research right now, but I recommend checking clinical trial registries for more info.
