“I was in a coma for four days from bacterial meningitis. When I woke up, I was completely deaf! I had to communicate with my parents and doctors with a notepad and pen. Some hearing gradually returned in my left ear, but my right ear is still 100% deaf to this day.” Deafness is not a particularly common symptom of comas. However, during a coma, the brain is in a state of altered consciousness and may not process sensory information in the same way it does when a person is awake. In some cases, this can result in sensory deficits, including hearing loss.
