Would you want to know? Public attitudes on early diagnostic testing for Alzheimer's disease.

Introduction: Research is underway to develop an early medical test for Alzheimer's disease (AD).

Methods: To evaluate potential demand for such a test, we conducted a cross-sectional telephone survey of 2,678 randomly selected adults across the United States and four European countries.

Results: Most surveyed adults (67%) reported that they are "somewhat" or "very likely" to get an early medical test if one becomes available in the future.

The Impact of Experience with a Family Member with Alzheimer's Disease on Views about the Disease across Five Countries.

The objective of this paper is to understand how the public's beliefs in five countries may change as more families have direct experience with Alzheimer's disease. The data are derived from a questionnaire survey conducted by telephone (landline and cell) with 2678 randomly selected adults in France, Germany, Poland, Spain, and the United States. The paper analyzes the beliefs and anticipated behavior of those in each country who report having had a family member with Alzheimer's disease versus those who do not.
