There's a lot of scientific evidence that medical marijuana can remove beta-amyloid build up in the brain. There is also evidence that unknown spirochete diseases can cause Alheimer like symptoms. There is also cause for concern that bio-pesticides that are GMO based are can infect the brain and cause symptoms like this as well. I would definitely never give up if this happened to me. Antibiotics, antiparasite, diet changes, small microdosages of CBD/THC based marijuana strains, neuroprotective compounds, etc --- all through a process of elimination with a journal. I hope Jo or somebody like Jo reads my comment and tries these things.
