Billy Joel undergoes shunt surgery after linking hydrocephalus to loud concerts
Billy Joel, 77, underwent brain-shunt surgery in Connecticut after doctors linked his normal-pressure hydrocephalus to repeated exposure to loud rock concerts, and he is now undergoing physical therapy, Fox News reported. Rolling Stone earlier reported that the singer said the condition forced him to pause touring because live performances were damaging his brain. NBC News later disclosed that the shunt implantation improved his balance and memory and that he will continue following medical advice.
