Effects of aging: general: overall, there is a decline in acuity in all senses with age, vision, audition (hearing, somatosensory (touch, gustatory (taste, olfactory (smell, vestibular (balance) Visual changes in aging: visual acuity declines because of, changes in the visual system that occur with normal aging, can also be affected by a number of disorders that increase in prevalence with age, e. g. , macular degeneration, cataracts. Auditory changes in aging: similarly, auditory acuity is affected because of, normal changes with age (e. g. , reduction in flexibility of parts of the auditory system) increased risk of disorders that result in hearing loss (e. g. , tinnitus) Thought question: at what levels do you think reductions in sensory acuity impact older adults, cognitive, psychosocial, virtual dementia tour, http://www. youtube. com/watch?v=sj4w-qstq6s. Hearing loss is more severe at higher frequencies (presbycusis) Declines in auditory acuity result in impaired language comprehension in many older adults that some sounds are affected more than others.
