Define Alzheimer's Disease and Explain the Progression of the Disease

Question

Examlex · Accepted Answer

The Answer is Alzheimer's disease is a chronic degenerative illness in which changes in nerve fibers in the brain result in mental deterioration affecting memory, speech, and personality.
It progresses in stages, each of which is marked by increasingly impaired memory and judgment. In later stages of the disease these symptoms can be accompanied by agitation and restlessness (especially at night), loss of sensory perceptions, muscle twitching, and repetitive actions. Many patients become depressed, combative, and aggressive. In the final stage, disorientation is often complete. The person becomes dependent on others for eating, dressing, and other activities. Identity loss and speech problems are common. Eventually, control of bodily functions may be lost.
