Alzheimer's Disease (cont.)
IN THIS ARTICLE
Researchers have discovered changes that take place in the brains of people who have Alzheimer's disease. These brain changes may cause the memory loss and decline in other mental abilities that occur with Alzheimer's disease. It's not fully understood why these brain changes occur in some people but not in others.
Alzheimer's disease always gets worse over time, but the course of the disease varies from person to person. Some people may still be able to function relatively well until late in the course of the disease. Others may lose the ability to do everyday activities very early on.
A person with severe dementia becomes more vulnerable to other illnesses, such as pneumonia.
