Reports of brain worms, similar to the one alleged by Robert F. Kennedy Jr.'s campaign over ten years ago, are indeed factual — and these infections are more prevalent in specific regions of the world than commonly believed.
During an appearance on "CBS Mornings" Thursday, CBS News medical expert Dr. Céline Gounder verified the existence of parasitic infections that can affect the brain. Infections such as tapeworms in the brain, known as neurocysticercosis, can be acquired through the consumption of undercooked, contaminated pork or by drinking unclean water.
"Typically, this occurs in regions with poor sanitation and inadequate water quality," she explained, highlighting that it is "a leading cause of seizures worldwide in areas lacking proper water and sanitation."
A representative for Kennedy's campaign, Stefanie Spear, mentioned in a communication with CBS News that the presidential candidate developed the infection after extensive travel "throughout Africa, South America, and Asia in his role as an environmental activist."
What are the ways to contract brain worms?
Upon ingestion of minuscule tapeworm eggs, they hatch into larvae that can invade various organs, including the brain, muscles, liver, and other tissues.
"The transmission of these parasites typically occurs when parasite eggs are present in feces and then individuals consume contaminated food or water, leading to contamination of their hands," explained Gounder.
In a 2012 deposition, Kennedy mentioned that a parasitic worm had "eaten a portion" of his brain which may have contributed to cognitive issues, as reported by The New York Times. However, Gounder clarified that these parasites do not actually "eat" the brain.
"The most probable type of parasite he may have had is related to a pork tapeworm cyst, which typically remains in place. While they may grow and cause inflammation or swelling, resulting in symptoms, they do not consume the brain," she added.
Symptoms of Brain Worm Infection
Common symptoms of brain worm infection include nausea, vomiting, headaches, and seizures, according to Gounder. However, many individuals infected with this type of parasite may not display any symptoms.
Treatment for tapeworm infections typically involves the use of medications like anti-parasitic drugs to eliminate the worms. In some instances, if the worm dies, the body's immune system may naturally clear the deceased worm from the brain tissue without the need for surgery, unless complications arise. Kennedy mentioned to the Times that he did not require any treatment for his parasitic condition.
Gounder explained that these parasites are usually "encapsulated by the immune system and become calcified over time."
Many individuals may not even realize they have this condition until symptoms such as seizures or headaches arise. In some cases, it may be discovered incidentally during a scan for another purpose.
