July 20, 2011 (Paris) -- Alzheimer's is the second most feared disease after cancer, even though many people do not realize it is inevitably fatal, a U.S. and European survey shows.

More than eight in 10 respondents said they would see a doctor if they were experiencing confusion or memory loss to determine if the case was Alzheimer's disease. And nearly all would take a loved one exhibiting these symptoms for evaluation, says Robert Blendon, ScD, professor of health policy and political analysis at the Harvard School of Public Health.

However, 38% to 59% of respondents mistakenly believe that there is a reliable test to determine if a person is in the early stages of Alzheimer's, according to the findings, presented here at the Alzheimer's Association International Conference.

Expectations High

Recent studies suggest that Alzheimer's starts developing a decade or more before symptoms appear. As researchers work toward the ultimate goal of developing drugs to prevent and treat the disease, early detection will be crucial, Blendon tells WebMD.

"The questions we wanted to answer were: Will people come for testing? And what would happen if they did?

"We found a large proportion of people will come, but they may come with high expectations [that we have more to offer than we currently have]," he says.

The telephone survey involved 2,678 adults in the United States, France, Germany, Spain, and Poland.

When asked to identify the most feared disease out of a list of seven that included cancer, heart disease, and stroke, about one-fourth of respondents from four of the five countries cited Alzheimer's. In the fifth, Poland, only about 12% did.

Between one-third and two-thirds of people -- from 35% in the U.S. to 62% in Germany -- mistakenly believe Alzheimer's is not a fatal disease. (There are some drugs like Aricept, Cognex, Exelon, and Razadynethat boost mental functioning in a small percentage of people for a time, but none halts the inevitable progression of the disease).

About three-fourths of people surveyed said they know or have known someone with Alzheimer's disease.

About two-thirds of respondents say they would get tested to see if they were likely to develop the disease, even if they had no symptoms.
