“The world only exists in your eyes,” was a quote from F. Scott Fitzgerald. This statement is very relevant when we think of our senses such as sight and hearing and their impact on the aging process and dementia.
Numerous studies have demonstrated an association between sensory impairment and cognitive decline. There are a number of reasons that loss of sight and hearing could contribute to an increased risk of dementia. Many of these involve increased social isolation or decreased cognitive stimulation as a result of the sensory impairment.
