I won‘t speculate about the feasability in humans, but at least in a mouse model, it looks like it‘s possible to at least partially reverse some symptoms: https://www.sciencedaily.com/releases/2018/02/180214093712.h...

I'm wondering, after the recent finding that herpes anti virals can reduce the chance of getting alzhemiers by up to 10x whether its worth trying them on my dad who's got some kind of dementia. Not sure if it's got a chance of working. The drugs are fairly cheap widely available and low side effects - the same stuff you take for cold sores. I guess the idea would be if you could control viral stuff the bodies normal repair mechanisms could help.

It sounds like you take some concern into your dads health and that you care. I would encourage you to be open and ask questions and find the information you need to help how you can. Maybe that is talking to your mom or if he is alone perhaps start a conversation with his doctor. If this is just something you have noticed but hasn't gone through the doctor I highly encourage you to do so. There are several causes to dementia. One being Alzheimer's as most know example but there are other types of dementia like vascular dementia where medications absolutely can help to some extent. Anyways don't be afraid to ask the questions. Wish you and your family best regards with all this.

IT may be more like - give mom the ability to re-learn who I am. Once AD hits, the memories are destroyed, so if things get restored, it may very well be a new a different person. Albeit one with the ability to learn and retain memories.

Is that something we actually know, that it's the storage area that's damaged and not the retrieval pathways?

Presumably you would treat during early onset.

The adult brain has some limited ability to recover from injuries. It's quite possible that if an aggravating factor was removed, Alzheimer's patients could slowly improve.
