Presidential candidate Robert F. Kennedy Jr. revealed that he was diagnosed with mercury poisoning around the same time doctors discovered a parasitic worm in his brain, adding to questions about the cognitive fitness swirling the 2024 campaign.
Kennedy consulted neurologists about memory loss in 2010 and said a doctor told him a dark spot in a scan of his brain could be caused by a worm that ate a portion of his brain, according a deposition reviewed by the New York Times. He also attributed mercury poisoning to a fish-heavy diet.
