This document discusses sensory changes that occur with aging, including changes to vision, hearing, taste, smell, and touch. It covers normal age-related changes to each of the five senses, common causes of sensory impairment, nursing assessments related to sensory function, and potential nursing diagnoses associated with sensory problems in older patients. The overall focus is on explaining how the aging process impacts the five senses and providing guidance to nurses on assessing and caring for older patients with sensory impairments.
