Progression
Alzheimer's disease is a progressive, degenerative disease that destroys vital brain cells. As each area of the brain is affected, certain functions or abilities can be lost. The losses affect the individual's ability to think, to remember, to understand and to make decisions.
In addition to affecting a person's mental abilities, Alzheimer's disease affects moods and emotions. Along with loss of abilities, changes in behaviour occur. Gradually, independence disappears.
