About this study
The investigators' goal is to determine if certain tests of memory and attention, performed while sleepiness is induced by a single dose of lorazepam, can predict whether or not an individual is at risk for developing Alzheimer's disease.
Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
