Hello? P. Yoelli is a murine parasite (affects mice, typically tree rats, not humans). It does not cause vivax malaria in humans, P. vivax does. It’s falciparum, not vivax, that goes cerebral.
Ivermectin is not used to treat malaria.* You must be confusing it with hydroxychloroquine, which is.
I have seen cerebral malaria up close and personal (horrible seizures, arched back, etc). Brain fog it ain’t.
A myriad of diseases and medical conditions can cause brain fog (like low oxygen levels from COPD or Covid, or dehydration, or stress, vitamin deficiencies, lack of sleep, any number of things).
And what on earth has a malaria parasite got to do with HIV (retrovirus). It’s not even apples and oranges. It’s onions and elephants.
Also please see my #46 on this thread:

Finally, ivermectinis (A) not used to treat malaria and (B), even if it was (as hydroxychloroquine is) it could easily be both antimalarial and antiviral (again, see my #46).
*Ivermectin is an insecticide and it has been proposed it might be used to reduce the incidence of malaria, as mosquitoes feeding on humans and animals being treated with ivermectin have a shorter lifespan. That is far from being used to treat the disease itself.
