Detecting Hearing Loss

Because many persons with traumatic brain injury are in a coma or otherwise unable to communicate their problems, it is often a bit difficult to determine if hearing loss is part of the injury. A recent study (Lew H. L. 2004) showed encouraging results by having the individual undergo brain stem auditory evoked potential. They follow this test up with CT scan of the bilateral temporal bones. Use of these two tests may prove valuable in ruling out hearing loss in those with severe TBI.
