The purpose of this study is to develop a recruitment registry of potential drug study participants who may have amyloid, a specific biomarker for Alzheimer's disease, using a phone assessment of cognitive and behavioral functions. The investigator uses the responses to the phone questions to predict which participants most likely would show amyloid should they have a PET brain scan. An amyloid positive PET scan is required to enroll in the majority of Alzheimer drug studies.

People must live around  San Antonio, Texas or close area within the city 


There is one phone call for the participant that takes 30 to 45 minutes and one optional phone call with a caregiver/ study partner that takes 30 minutes.
