Luckily there is a treatment protocol that can reverse Alzheimer’s. Big Pharma hates it because it is not based on any expensive drug.
See Dr. Bredesen’s book - The End of Alzheimer’s or his latest pilot study https://content.iospress.com/articles/journal-of-alzheimers-disease/jad215707
I know it can work for MCI and early stage Alzheimer’s. I am an Apoe4/4 genotype ( the Alzheimer’s gene) and I recovered from Mild cognitive impairment related to AD using the protocol. My short term memory score went from 24th percentile to 91st. If you catch it early there is hope.
