I didn't read through all the posts, so I don't know if this was posted already...sorry if it was. Dysautonomia is a genetic and can be passed on, but that isn't always the case. Also, there is also a viral onset. Most of the people I know have the viral onset. Although, myself, cousin, mom, & aunt have genetic. My mother, cousin, & I either have some sort of syncope or POTS OR both....Which My cousin and I do have both (lucky draw...which is what I tell her ) We all have FMS and CFS. My grandmother has migraines with the rest of us. I'll just stop with that. We have a laundry list.... I always tell them we are a special family. My cousin is 12... I do know your fear...I have 2 boys. My sister has 2 girls and one on the way. Also go to www.dynakids.org....it's a dysautonomic form for kids and parents. I know they have a lot of info on how dysautonomia and how it affects kids. I haven't checked the main page recently...so they may have put different articles up. Take care!
