Could a fecal transplant one day restore cognitive function in elderly?

Gut-brain connection was a great find and overall this is an exciting idea, despite how bizzare it seems on first read. I always find it funny though, if the fecal transplant practice is done without knowing the whole scientific context, it sounds like a witch-doctory treatment.

  Actually it is not a so new idea, for example the first publication I can find with this mention (brain-gut axis) is from 1980 [0] Since there were nearly 3 thousands publications, but no real breakthrough in medicine.

    Ah, forgive my ignorance and thanks for the insight.

  Many treatments around the mind aren't completely understood, they've just been proven to work without too many side effects. I think fecal transplants have a proven, or near proven ability to treat obesity and diabetes and used after illness or antibiotics have wiped out a patients gut microbiome. Pro biotic supplements are already derived from fecal matter and widely accepted. Under the right conditions its probably a low risk procedure.

Looking forward to future results testing the other direction.

So one day it might be possible to literally have shit for brains.

  That’s a quite shitty response

Well, some people do have shit for brains, so this might work...

    Humour is frowned upon in these parts lest it becomes the toilet that is Reddit.

      Because humor is less important?

        Nope. Sorry my comment was a facetious stab at the lack of comedy here. It’s essential and lacking.

if anyone wants a billion dollar idea that is unfortunately too early for the world, it's the sperm-bank equivalent for fecal transplants, and if you really wanna go luxury / premium go the Cameo route and create a marketplace to get high performers and celebrities' poop on a marketplace for people to buy and use for transplant.
