The 5 senses are hearing, sight, taste, smell, and touch. Each of the 5 senses may become less sharp with age. Details or subtle differences a person once appreciated may go unnoticed.
Sensory changes can have tremendous impact on an individual.
These changes may make it hard for a person to communicate, enjoy certain activities, and interact with others. This can lead to feelings of isolation and loneliness. Through the senses that pick up light, sound, and temperature, for example, a person gains much information about the world. This information is changed into nerve signals and carried to the person's brain. There, it is turned into a message that he or she can understand.
