Tinnitus after a concussion or brain injury BPPV, or benign paroxysmal positional vertigo (the sensation of spinning).Vestibular ( balance) problems may include: auditory processing problems (you pass a hearing test but struggle to understand speech).aural fullness (ears feel like they can't pop).decreased sound tolerance for specific sounds.noise sensitivity or loudness intolerance.hearing loss, especially asymmetrical hearing loss or " double hearing".What auditory problems can be triggered by a TBI? Veterans are at particularly high risk for this kind of injury, resulting in high rates of tinnitus and hearing loss in the veteran community. When the head injury predominantly affects the ears (such as a blow directly to the ear, or a blast of noise at close range), it is known as an acoustic trauma. In a study of 395 patients age 14 and older who came to an urban hospital with a mild TBI, among those who met the usual criteria to be sent home without a follow-up, 27 percent actually turned out to have lasting cognitive problems, researchers said, and needed therapy. There is some evidence hospitals are undertreating TBIs considered mild. Also, your brain may be injured even if you did not lose consciousness.ĭoctors may use the word “concussion” rather than brain injury, especially when talking to parents, because it is less alarming. Note that the blow doesn’t have to be directly to your head for instance, if you are in a car accident and lurch forward violently, you could have a TBI even if your head doesn’t hit anything. It may also damage cells, as you can see in this illustration from the Centers for Disease Control and Prevention. Any bump, blow, or jolt that makes the head and brain move rapidly back and forth can make the brain bounce or twist within the skull, triggering chemical changes. Falls cause nearly half of all TBIs, followed by car crashes and assaults. The medical definition of a traumatic brain injury is a head trauma that temporarily impairs the normal function of the brain. Hearing loss and other auditory issues may have been missed or misdiagnosed. If you have a TBI in your history, even a mild one, be sure to tell your doctor or hearing provider. Sometimes problems are identified long afterward. It may take some time before “the patient reports signs and symptoms of audiological disorders or family members start noticing the signs,” notes Shahrzad Cohen, an audiologist based in Sherman Oaks, Calif., in a webinar for the Hearing Loss Association of America. The first goal for doctors in the aftermath of a TBI is to stabilize the patient. In the United States, people 75 years and older have the highest numbers and rates of TBI-related hospitalizations. Airbag injuries or blasts, for example, can affect them and trigger ringing in the ears, dizziness and hearing loss.Īnyone can have a TBI, but these events are more likely to be serious among older people. Have you been diagnosed with a traumatic brain injury (TBI) or concussion? Remember your ears.
