Tinnitus is a subjective complaint of hearing a sound or sounds that is attributed to the ears or the head. The sound is simple and has no linguistic meaning. In that respect it is different from auditory hallucinations.

Chronic tinnitus

We define chronic tinnitus as a persistent symptomatology of disturbing tinnitus for more than 6 months (see references (1) and (2) in the last chapter).

Vertiginous patients complain of a sensation that "the world is going around" or that the head is moving.

Dizziness is a complaint of "unsteadiness", "feeling of unclarity" or feeling of being "one second before fainting".

Unsteadiness includes patients who developed dizziness, vertigo or both, but do not have any known pathology outside the vestibular system.
