Jmo: She only drinks colas, eats junk foods, and cat hair. After years of consuming small amounts of cat feces in cat hair, she may have brain parasites, also, of which there is no cure.
My unofficial diagnosis: She needs iron, calcium, and zinc and in addition, she would benefit from a healthier diet, including food sources of manganese found in spinach, kale, chard, raspberries, pineapple, strawberries, romaine lettuce, collard greens, garlic, summer squash, grapes, turnip greens, eggplant, and brown rice.
FWIW, if you’re thinking of Toxoplamosis gondii, there are several antibiotics that are effective against it. (If you’re not, never mind.)
I pretty much figured the zoonoses angle was already locked in.
If I were her, I’d be getting tested for them.
Even Toxo can be treated somewhat.
[don’t know if the brain damage can be undone, though]
