Early detection fine. Early cure even better.
A cure is more likely if you can catch it before too much brain damage has occurred.
There is a lot of new research and evidence that many of the neurodegenerative diseases (Alzheimers, dementia, and others) stem from brain cells losing the ability to "burn glucose" and are basically starving (brain glucose dynamics differ from the rest of the cells of the body). This metabolic failure DOES NOT hinder the ability of brain cells to burn ketones. Switching from a diet with lots of carbs to one with almost no carbs, but "ketogenic" (high fat, moderate protein, very very low carbs) and the use of exogenous ketone supplements have resulted in some stunning recoveries from AD.
I got onto the intermittent fasting/ketogenic diet to reverse my Type 2 "pre-diabetes" (which it is doing), but references to Alzheimers keep popping up. My next-door neighbor (really nice guy) has just been diagnosed with "mild cognitive impairment" (basically pre-Alzheimers), which has triggered me to shift my keto research more to Alzheimers than diabetes.
