We have and had several friends/relatives with Parkinson’s and alzheimer’s. Zero of these patients have had any signs of impaired immune systems before their diagnosis were made.
They have ended up in PT programs for patients with Parkinson’s, take their meds, eat healthy Paleo diets and continue fish, kayak, run, walk or whatever they did before they were diagnosed with Parkinson’s. Many have added weight lifting to their exercise/PT programs.
Hopefully, this is not a scam to get funding as funding is going to get tighter.
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.
FWIW, I think it’s worth researching. Even if the parasite isn’t responsible for most cases. We’ve had three cases of dementia in the family. One Alzheimers, one vascular, one undetermined. One of the family members afflicted is a recovering crazy cat guy. We’ll be discussing the parasite with his doc at his checkup in a couple of weeks.
