A recent study shows how even mild-moderate hearing loss might influence brain processing 

By Hannah Glick, AuD, PhD, and Anu Sharma, PhD

One of the most amazing abilities of the human brain is its capacity for change. The term neuroplasticity refers to the brain’s ability to adapt or change. While the brain is most amenable to change early in development (developmental neuroplasticity), neuroplastic changes may occur across the human lifespan as a result of disease, injury, dysfunction, and learning (adulthood neuroplasticity). Based on our findings, it appears that untreated hearing loss (even mild sensorineural hearing loss) is associated with neural reorganization and cognitive deficits.
