  1. This is a poor model of AD.

Yes! Mice do not get Alzheimer's, so we rely on a transgenic mouse model to exhibit the symptoms. The problem is that Alzheimer's isn't well understood, so it isn't clear how good mouse models are, and prior treatments effective in mouse models haven't proven effective in humans. This article is effectively hype.

    I would add it's long been known now that brain cells can regenerate. Even longer has it been known the brain can reprogram around damaged cells, to a point, it's complicated obviously.

    Around 2013 or so, there was a british columbian study where they gave brain damaged rats a type of super cannibinoid, like hundreds of times THC potency, and they regrew their brain cells, never heard any follow up studies on it.

    But in the 90s the mantra was that brain damage was always permanent, a message in service of keeping the kids of the marihuanas.
