I thought you may have been doing this already as you had mentioned epilepsy elswhere and seemed pretty keyed up on the Ketosis thing, so I just assumed.
I have no experience in it, but read about it a while back, seems it was the original treatment for epilepsy until drugs became commonly available, but has made a resurgance in recent years particularly in the treatment of drug resistant epilepsy. I became interested when I read about the high fat diet kid, some article in the New York times a few years ago, he had severe epilepsy, he had up to 130 seizures per day quoted, Link below:

So I looked into the Ketogenic diet for other health benefits, seems there has been some promising work in other neurological conditions like Alzheimers, although not reversing it did seem to halt progression and Parkinsons they are just starting to do trials.
So good luck with it.
