点击翻译按钮获取中文摘要

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This is an instrument protocol in which various novel instruments are tested for their future utility in primary prevention trials for Alzheimer's disease. Simultaneously, three methods of test administration are being tested: in clinic, at home, and web-based methods. This trial is fully enrolled, with 31 subjects involved in the trial, which will span the next four years for longitudinal data collection. No consent form document is enclosed since the study is closed to enrollment.
