Abstract
The effects of hearing loss on neural processing and plasticity.
Highlights
Hearing loss—ranging from mild to severe—afflicts large numbers of individuals of all ages
It is estimated that 40–50% of adults over the age of 65 years have some degree of significant hearing loss, with this figure rising to 83% of those over the age of 70 (Cruickshanks et al, 1998)
Speech comprehension in the face of mild-to-moderate hearing loss modifies patterns of neural activation in BOLD imaging, and analyses of structural MRI images have shown that poor hearing acuity is associated with reduced gray matter volume in auditory cortex (Peelle et al, 2011; Eckert et al, 2012; Lin et al, 2014)
