The man over the health, making decisions for this country Robert F. Kennedy Jr. got a brain worm (likely a pork tapeworm larva) by ingesting its eggs, probably while traveling in Asia, South America, or Africa, where the parasite is more common. He described experiencing memory loss and brain fog, which led doctors to discover the parasitic cyst in his brain, though it eventually died and required no treatment. How It Happens (Neurocysticercosis): Ingestion of Eggs: A person gets infected by swallowing eggs from the pork tapeworm, Taenia solium, often through contaminated food or water. Larvae Travel: The eggs hatch, and the larvae travel through the bloodstream to other organs, including the brain. Cyst Formation: In the brain, the larvae form cysts, a condition called neurocysticercosis. RFK Jr.'s Experience: Symptoms: He reported severe memory loss and brain fog, leading to a diagnosis where doctors found a dead parasite cyst in his brain. Location: He suspected he contracted it during travel in South Asia. Resolution: The infection resolved on its own, with the parasite dying and no specific treatment needed for the cyst. While he mentioned high mercury levels as a potential cause for brain fog, the parasite infection was identified as the source of the cyst
