Brain worms like the one RFK Jr. had are real and more common than you might think, doctor explains

Brain worms, like the one Robert F. Kennedy Jr.'s campaign said he contracted more than a decade ago, are real — and the infections are more common in certain parts of the world than you might think.

On "CBS Mornings" Thursday, CBS News medical contributor Dr. Céline Gounder confirmed there are parasitic infections you can get in your brain. Tapeworm infections of the brain, or neurocysticercosis, can be contracted from consuming undercooked, infected pork or drinking contaminated water.

"Usually this happens in countries where you have poor sanitation, unclean water," she said, adding it is "one of the most common causes of seizure around the world where you don't have good water and sanitation."
