Tinnitus is associated with improved cognitive performance and speech perception–Can stochastic resonance explain?

Abstract

Subjective tinnitus is a perceived sound in the absence of any objective sound source. This phantom perception has severe consequences, ranging from insomnia to depression or even suicide. Furthermore, tinnitus is assumed to accelerate cognitive decline. However, a recent study showed that in non-hispanic elderly people, tinnitus is associated with a better cognitive function compared to an age-matched control group.
