Hearing troubles are very widespread soon after a traumatic brain injury (TBI) due to the fact the inner ear is straight connected to the central nervous program. Ringing in the ear (tinnitus) and hearing loss are two of the most extensively reported side effects of a traumatic brain injury. Some other hearing issues that may possibly happen soon after a brain injury incorporate hyperacusis (typical scenarios look quite loud); trouble filtering one particular set of sounds from background noise; and auditory agnosia (also named pure word deafness). Auditory agnosia is a situation in which the particular person is unable to recognize the meanings of specific sounds.
After a TBI, hearing difficulties can happen for a quantity of motives, each mechanical and neurological, specifically when the inner ear and/or temporal lobes have been broken.

Simply because hearing loss limits or requires away a single of the main indicates we use to communicate, hearing loss has the possible to complicate numerous of the other side effects of brain harm, primarily cognitive and social difficulties. Quite a few TBI victims currently endure cognitive problems such as trouble discovering words, and these challenges are only exacerbated if the patient can't hear what is going on about him.
Luckily, for some TBI victims, hearing issues disappear a handful of weeks following the accident that led to the patient's brain harm, but other hearing difficulties will final indefinitely. Due to the fact numerous hearing challenges can not even be detected by the patient himself right after the TBI, it is suggested that anybody suffering a traumatic brain injury be evaluated by an audiologist, even if absolutely nothing seems to be incorrect with the victim's hearing.
