Some sensory changes begin in early middle age. They are progressive and are apt to cause limitation of activity in later years. All sensory organs show some degree of altered function by the age of 70. In general, the changes in sensory function due to aging include a higher sensory threshold (level of strength a stimulus must reach to be detected) and a decrease in sensory acuity (actual physical ability of the sensory organs to receive input). Natural changes in vision, hearing, taste, and smell occur as one ages.
