The longest brain dead person kept alive is Jahi McMath, a 13-year-old girl who suffered from complications after a tonsillectomy at Children's Hospital Oakland in California. Jahi was declared brain dead on December 12, 2013, but her family refused to accept the diagnosis and sought medical intervention to keep her alive.
Jahi's family was able to secure an injunction allowing her to be kept on a ventilator and transferred to a long-term care facility in New Jersey. She remained on a ventilator for five years, until her death on June 22, 2018. During that time, her family and medical team provided her with nutrition, hydration and basic medical care.
The case of Jahi McMath has been highly controversial, as it stirred up debates about the definition of death, the right of families to make medical decisions, and the ethical implications of keeping a brain dead person alive. Despite the controversy, her case demonstrated the incredible lengths to which families will go to keep their loved ones alive.
