My parents both had / have Alzheimer’s. They never had a cat.
I’ve always had a cat but never tested positive for toxoplasmosis (they test you when youre pregnant).
All this research is very interesting but no one seems to nail a cause.
You can get it from meat. Not sure what else besides meat and cats.
You bring up an interesting point re cat ownership.
My MIL had Alzheimer’s and she hated cats. She and her husband had Cocker Spaniels until their last child became an adult and left home.
A current friend with Alzheimer’s was/is allergic to cats.
None of our friends, relatives, in laws with Parkinson’s has/had cats. In fact they are real dog people. Whenever, a dog goes to doggie heaven, they get a new one.
“My parents both had / have Alzheimers. They never had a cat.”
Were your parents like my MIL and our current friend with Alzheimer’s, disgustingly healthy until the Alzheimer’s came?
