According to research, the number of people who have survived brain stem death is extremely low. Brain stem death is a severe medical condition in which the brain stem, the part of the brain responsible for regulating vital body functions, is completely non-functional. This condition is irreversible and is considered the most severe form of brain death.
Due to the severity of this condition, it is often impossible to revive the patient and as such, very few people have survived brain stem death. However, a few cases have been reported and documented where patients have recovered, albeit with extensive medical interventions and therapies.
One of the most high-profile cases of a person surviving brain stem death was that of Jahi McMath. In 2013, McMath underwent a tonsillectomy and suffered from severe brain swelling, leading to brain stem death. Despite the odds, McMath was eventually moved to a long-term care facility and made a remarkable recovery.
In addition to McMath, there have been several other cases of people surviving brain stem death. For example, in 2017, a 15-year-old girl in China survived after her brain stem was damaged due to a severe infection. In 2019, a 10-year-old girl in the United States made a full recovery after suffering from brain stem death due to a brain tumor.
Overall, while the number of people who have survived brain stem death is extremely low, there have been a few cases around the world where patients have recovered with extensive medical interventions and therapies.
