Differential Diagnoses
Workup
Laboratory Studies
Evaluation may entail a variety of tests, including blood tests for autoimmune-induced hearing loss.
Imaging Studies
Evaluation may entail a variety of tests, including CT scanning or MRI to exclude anatomic abnormalities or mass lesions that may cause hearing loss.
Other Tests
- Audiometric testing with pure-tone average and speech discrimination forms the cornerstone of diagnostic testing for presbycusis.
- The need for additional testing can usually be determined from the audiometric test results. For example, individuals with asymmetric hearing loss (ie, more than 10 dB difference at any 2 consecutive frequencies) and individuals with a conductive component require further evaluation.
- Evaluation may entail a variety of tests, including tests of central auditory processing to exclude abnormal processing of auditory information in the central nervous system.
