Not a medical person, but don't think seizures start at 68,...Alzheimer's’ maybe....;~)
I know a person in his 40s who has seizures, and I’ve seen him when one happens. He has no DL, but seizures aren’t the reason he can’t drive.
He’s a drunk and a doper with multiple DUIs. Whether the liquor and drugs have anything to do with causing his seizures, I don’t know, but I guarantee they don’t help.
