Tinnitus is a sound perceived without external stimulus, and results from the dynamic interaction of the centers in the central nervous system, including non-auditory and auditory ways. The result of this interaction, especially with the limbic system and autonomic nervous system, would be responsible for triggering negative emotional associations and distress in patients with tinnitus. Anxiety, a physiological condition inherent to human beings, when exacerbated, generates a mood disorder, affecting thinking, behavior and physiological activity. If an inner or outer stimulus is interpreted as dangerous or threatening, it may trigger an emotional reaction characterized as a state of anxiety. This work aims to review the relationship between tinnitus and anxiety. The tinnitus sound is perceived can be altered by anxiety, thereby, sharpening the sensitivity in detecting sounds that seem a potential threat, because for many people, tinnitus is synonymous with a serious illness. The etiology for the development of depression and anxiety may be related to tinnitus. Many people acquire this symptom by physical problems and hence develop depression and anxiety. Others with different degrees of distress due to tinnitus acquire emotional problems. Thus, there is a probable link between tinnitus and emotional problems, but it is not always easy to identify which one occurs first. Studies show that patients affected by tinnitus have a greater trend for suicide, depression and anxiety. They also refer to the additive cumulative effects of anxiety and depression on the quality of life of tinnitus sufferers.
