Korean-American comedian Johnny Yune is in a sanatorium in Los Angeles with advanced dementia.
Yune has been confined to a wheelchair due to limited mobility. A friend told reporters Yune "keeled over from a brain hemorrhage in spring this year."
Yune made his debut in Korea in 1959. He moved over to the U.S. in 1962 as an international naval cadet and resumed his career as a stand-up comedian.
He became popular after appearing on NBC's "Tonight Show" with Johnny Carson and then hosted "Johnny Yune Special Show" on the same network.
He returned to Korea in 1989 and became a popular talk show host.
Yune was treated at Asan Medical Center for a cerebral hemorrhage in April last year and returned to Los Angeles several months later.
