Chronic tinnitus prevents the brain from entering the resting state normally.
Evidence
Specifically in patients with tinnitus, the DMN does not clearly show a task-effect, which in contrast is clearly present in controls. This observation enhances the hypothesis that subjects with tinnitus cannot get the ‘rest’ that is necessary for a healthy life. In conclusion, we attribute the pattern of reduced connectivity in the DMN to the unremitting engaging effect of the tinnitus percept. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2747 (
