Betty White’s cause of death has been confirmed.
White’s death certificate lists a cerebrovascular accident as her immediate cause of death.
A cerebrovascular accident, which is a medical term for a stroke, occurs when blood flow to the brain is interrupted, according to Johns Hopkins Medicine. When the blood supply is stopped, the brain cells begin to die and the brain loses function.
According to the death certificate, “The Golden Girls” star suffered a stroke six days before her death on Dec. 31 at age 99.
White’s agent and close friend Jeff Witjas said in a statement given to NBC News: “I was told that Betty passed in her sleep peacefully without pain. To me, this is the most important thing and brings me comfort as her friend. Anything else is private to Betty.”
