Answers

1. A is the correct answer.

Estimates vary, but experts suggest that as many as 5 million people in the United States may have Alzheimer's disease. Most of them are age 65 or older, but those with a rare, inherited form may be in their 30s, 40s, and 50s.

2. A is the correct answer.

Increasing age is the most important known risk factor for Alzheimer's disease. The disease usually begins after 65, and the risk goes up with age.

3. C is the correct answer.

Family history is another risk factor for Alzheimer's disease. Scientists have found genetic links to both early-onset and late-onset Alzheimer's disease. Over recent years, more than a dozen gene variants have been linked to late-onset Alzheimer's disease, the most common form of the disease. Researchers have also identified genes involved in the rare, early-onset form of Alzheimer's. Discovery of genes—both that confer risk and offer protection—may help researchers to more effectively test possible treatments and prevention strategies in people who are at risk of developing Alzheimer's—ideally, before symptoms appear.

4. D is the correct answer.

Some observational studies have linked controlling blood pressure, being physically active, and eating a healthy diet with a reduced risk of developing Alzheimer's disease. Currently, there are no lifestyle treatments, drugs, or pills that have been shown to prevent Alzheimer's disease.

5. D is the correct answer.

Although there is no cure for Alzheimer's disease, early diagnosis makes it possible to consider treatment options and make legal and financial arrangements while the person with Alzheimer's can still take part in making decisions. Early treatment may help the person function independently for longer. Also, doctors may find other possible causes of the person's symptoms, such as thyroid problems, drug reactions, depression, brain tumors, or blood-vessel disease in the brain. Some of these other conditions can be treated successfully.

6. C is the correct answer.

With Alzheimer's disease, the time from diagnosis to end of life varies. It can be as little as 3 years if the person is over 80 years old when diagnosed, or as long as 10 years or more if the person is younger.

7. D is the correct answer.

Memory aids may help some people with mild Alzheimer's disease with day-to-day living. A big calendar, a list of daily plans, notes about simple safety measures, and written directions describing how to use common household items can be useful.

8. C is the correct answer.

A person's genetic make-up can affect the risk of developing both early- and late-onset forms of Alzheimer's disease. Early-onset Alzheimer's, a rare form of the disease affecting 5 percent or fewer of people with Alzheimer's, can be directly inherited. One gene—apoE4—may increase a person's risk of having the common, late-onset form of the disease, which occurs after age 65.
