Sorry I took so long to get back to this...
Yep. The idea is that glutamate neurotransmitter receptor sporting cells can be driven to energy failure under certain conditions. Adding ketones as an alternative to glucose appears to supply energy to allow both survival and improved function of neurons which are doing very badly on glucose.
This story has been on the internet for a while now and it seems some people with a certain gene will get some relief with MCT oil or coconut oil (contains MCTs) that then get converted in the liver to ketones:

And ketogenic diets have been used to partially REVERSE Parkinson's:

It appears that if you feed dopaminergic brain cells on ketone bodies they stop dying, and maybe the sick-but-not-yet-dead ones recover. The brain likes ketone bodies.
I'm still on the early part of the learning curve with all this...so maybe these approaches have since fizzled out??
You're doing this yourself, or you're following the research - or both?
Please tell me more!
Thanks!
