这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 这是一种仪器方案，在该方案中，将测试各种新型仪器在阿尔茨海默病初级预防试验中的未来用途。同时，正在测试三种测试管理方法：临床、家庭和基于网络的方法。这项试验是完全登记的，有31名受试者参与试验，试验将跨越未来四年进行纵向数据收集。由于这项研究不对登记开放，因此没有附上同意表格文件。

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.
