After all my ramblings on the statistical information surrounding Evan's seizures, the only conclusion we could come up with is that we need more data. We are seeing a couple days a week with no seizure activity and this is really reassuring! So, we canceled the appointment with Johns Hopkins (to start the Ketogenic Diet) and are going to give Vigabatrin a little more time to see if it works for Evan.
We increase Evan's Vigabatrin every Tuesday and we'll be interested to see what the next couple days bring, but Evan has had 3 seizure-free days since Tuesday. We flip-flop between feeling hopeful and helpless and it's nice to be on the hopeful side for a change!
