Abstract: Hearing loss is a principal modifiable driver of cognitive decline and dementia. This article examines the physiological and psychosocial mechanisms linking peripheral auditory dysfunction to memory impairment. A review of epidemiological and longitudinal clinical data—drawn from 1,275 subjects monitored over 25 months—demonstrates that individuals with untreated hearing loss experience accelerated cognitive decline. Early audiological intervention, including hearing aids or cochlear implants, represents a critical neuroprotective strategy capable of substantially delaying or mitigating the progression toward secondary dementia.
