<unk>  usually starts confined to one ear; it extends to both ears in about 30% of cases. People may start out with only one symptom, but in MD all three appear with time. Hearing loss usually fluctuates in the beginning stages and becomes more permanent in later stages. MD has a course of 5–15 years, and people generally end up with mild disequilibrium, tinnitus, and moderate hearing loss in one ear.
