Definition of Tinnitus
Tinnitus is a condition when a person hears a ringing sound or a different variety of sounds when no corresponding external sound is present and that other people cannot hear. The word tinnitus comes from the Latin tinnire, "to ring".
Tinnitus may be associated with hearing loss or decreased comprehension of speech in noisy environments. It is common, affecting about 10–15% of people. Most tolerate it well, and it is a significant (severe) problem in only 1–2% of people.
Rather than a disease, tinnitus is a symptom that may result from a variety of underlying causes and may be generated at any level of the auditory system as well as outside that system. The most common causes are hearing damage, noise-induced hearing loss, or age-related hearing loss, known as presbycusis. Other causes include ear infections, disease of the heart or blood vessels, Ménière's disease, brain tumors, acoustic neuromas (tumors on the auditory nerves of the ear), migraines, temporomandibular joint disorders, exposure to certain medications, a previous head injury, and earwax. In some people, it interferes with concentration, and can be associated with anxiety and depression. It can suddenly emerge or increase during a period of emotional stress. It may have a higher incidence in people with depression.
