Hearing loss is a common phenomenon and it could affect individuals across all age groups. The main causes for hearing impairment could be hereditary factors, trauma, ear disease, noise exposure, and most importantly, age. Hearing loss is known to trigger cognitive decline and memory loss in older adults. Audiologists have been seeing a boost in demand for their services by aged clients whose communication issues are triggered by hearing impairment and cognitive decline. For all these aged people, early detection or diagnosis of cognitive decline is crucial as it is mandatory to provide prompt medical intervention and also assure social support.
