Brain tapeworm

 RFK Jr said he had a brain tapeworm. 

the doctors thought it was a pork tapeworm.

old article on tapeworm in the brain.

The brain tapeworms, which cause a disease called neurocysticercosis, are most common in Central and South America. While the disease is rare in the US and Europe, the disease is "still frequently diagnosed" in migrant populations from the endemic areas, the study says. The researchers also estimate that in areas where the disease originated, 29 percent of epilepsy cases are caused by brain tapeworms. "Overall, 1.7 to 3 million persons are conservatively estimated to suffer from epilepsy due to NCC worldwide," the study says.

CDC page on the problemCysticercosis is a parasitic tissue infection caused by larval cysts of the tapeworm Taenia solium. These larval cysts infect brain, muscle, or other tissue, and are a major cause of adult onset seizures in most low-income countries. A person gets cysticercosis by swallowing eggs found in the feces of a person who has an intestinal tapeworm. People living in the same household with someone who has a tapeworm have a much higher risk of getting cysticercosis than people who don’t. People do not get cysticercosis by eating undercooked pork. Eating undercooked pork can result in intestinal tapeworm if the pork contains larval cysts. Pigs become infected by eating tapeworm eggs in the feces of a human infected with a tapeworm. Both the tapeworm infection, also known as taeniasis, and cysticercosis occur globally. The highest rates of infection are found in areas of Latin America, Asia, and Africa that have poor sanitation and free-ranging pigs

and yes there is a treatment: mild cases are merely observed and not treated, and severe cases require surgical removal. But anti parasitic medicines will sometimes work:

guidelines recommending use of albendazole with or without praziquantel for neurocysticercosis,

 but the authors also note: 

our case (as well as 4 other cases documented in the recent past) suggest a possible use of ivermectin as potential therapy for neurocysticercosis.

hmm... calling Ann Barnhardt: here's another use for Ivermectin.
