The purpose of the Alzheimer's Disease Registry Study (ADRS) is to (1) create a registry that will continue to provide study-ready subjects who meet research diagnostic criteria for the different stages of AD and who have been evaluated using research instruments that allow for their participation in clinical trial research, (2) provide a platform to allow for continual follow-up with registry participants to allow for their participation in clinical trial research at different stages of the disease process, and (3) to incorporate a population of veterans and minorities suffering from AD, a population that is not proportionally represented in clinical trial research, into the registry.
By collecting data pertaining to medical history, current medication details, family history, vital signs, and memory/thinking symptom concerns and evaluating a subject's ability to perform certain tasks, such as memory and thinking tests, questions about their daily activities, and social functioning; researchers are able to determine a research subject's potential eligibility in a clinical trial research protocol.
A registry with such information would enable researchers to effectively and efficiently identify potentially eligible research subjects for the program's evolving portfolio of Alzheimer's disease-related clinical trials.
The purpose of the study is to see if daily use of nicotine patches will slow or reverse memory loss in participants with Mild cognitive impairment, an early stage of mental decline associated with Alzheimer's disease. Nicotine may mimic natural chemicals in the brain that play a crucial role in memory function, and previous studies have shown that nicotine may improve attention, learning, and memory. In this study, participants will receive either nicotine (up to 21mg/day, the standard dosage of a nicotine patch) or placebo for 2 years to see if these improvements in brain function can be observed over a longer period.
