An inner ear condition that causes attacks of vertigo, hearing loss that may come and go, ringing in the ears, and ear pressure or fullness.
Because frequency of vertigo attacks is central to the rating levels, medical records that document how often attacks occur carry significant weight. Clinic notes, treatment records, or specialist reports that describe the number of vertigo episodes per week or per month directly correspond to the thresholds that separate 30%, 60%, and 100% ratings. Records showing cerebellar gait — an unsteady or staggering walk caused by the condition — are needed to support either of the two higher ratings.
Audiology reports and hearing test results help establish the hearing impairment component present at every level. Records noting tinnitus are also relevant, though tinnitus is not required at any rating level. Your own written statement, or statements from people who witness your episodes, describing how often attacks occur and how they affect your ability to work, drive, or carry out daily activities can help fill gaps between medical appointments. Statements about the unpredictability of attacks and their effect on your balance and mobility may reflect criteria at the higher rating levels.
