Sensory Input | General Description

Problems with sensory input can be a confusing area to understand.

As different areas of the brain are affected by Alzheimer's disease , changes can occur in a person's ability to understand what they see, hear, taste, smell, and touch. Normally, messages about your five senses are sent from the body to different parts of the brain. However, in Alzheimer's disease, the brain has difficulty understanding these messages. This results in a change or even a loss in how the person you care for senses portions of their environment.

Problems with how the brain evaluates information from your senses can lead to possible safety risks for the person you care for. They may be unable to smell something burning or tell if food is spoiled by sight or taste. As a result, it is possible that the person you care for might need help to understand the risks of their environment.
