Why did doctors find a dead worm in RFK Jr.’s brain? |

Presidential candidate Robert F. Kennedy Jr. recently announced that a 2010 scan found a dead worm in his brain. This discovery came after Kennedy sought medical attention for memory loss and brain fog, fearing he might have brain cancer. The condition, known as neurocysticercosis, occurs when tapeworm larvae invade the brain and form cysts. While the tapeworm itself does not cause any direct symptoms, the immune system’s response can lead to seizures and other neurological problems. While neurocysticercosis is rare in the United States, it is a significant problem worldwide, particularly in regions with poor sanitation and hygiene practices. Treatment varies, with antiparasitic medications being used during the active phase and surgical removal required in severe cases. Ultimately, once the worm has died and calcified, complications are minimal and the patient may experience relief from symptoms.
