Kennedy previously traveled to Kyoto, Japan, “to get a surgery, a procedure … that is not available here in the United States,” he previously told Vladislav “DJ Vlad” Lyubovny in an interview. Kennedy claimed the procedure involved placing “a titanium bridge between your vocal cords.”

What Is Spasmodic Dysphonia?
Spasmodic Dysphonia is a vocal disorder that involves sudden involuntary spasms affecting the vocal cords, causing them to stiffen and slam closed, according to Johns Hopkins Medicine. The most common form of the disease is known as adductor Spasmodic Dysphonia.
“The spasms interfere with vibration of the vocal cords and with making sound,” Johns Hopkins reported. “Stress can make spasms worse. Speech sounds are strained and full of effort. Spasms generally do not happen when whispering, laughing, singing, speaking at a high pitch or speaking while breathing in.”
What Is RFK Jr.’s Health History?
During his college years, Kennedy experienced heart issues, which he attributed to sleep deprivation, caffeine and stress, according to The Times. Other than that, RFK Jr. has also managed short-term memory loss, he previously told The Times.
“I have cognitive problems, clearly. I have short-term memory loss, and I have longer-term memory loss that affects me,” RFK Jr. said.
Kennedy also stated that his cognitive issues resulted from a “worm that got into [his] brain and ate a portion of it and it died.”
