Clinical Trials

The purpose of this study is to identify potential biomarkers that may predict the development of Alzheimer's disease in people who carry an Alzheimer's mutation.

There is evidence that high blood pressure can cause changes in memory and thinking as people get older. When the SPRINT study intervention was stopped in September of 2015, important data on long term rate of Alzheimer’s, change in cognition, and impact on the kidneys were not able to be collected. Participants from the SPRINT study will undergo a single SPRINT ASK visit approximately two years after their SPRINT closeout visit to assess blood pressure, cognitive and kidney function.

5.4 million Americans have Alzheimer's disease (AD) costing $185 billion annually, while 15 million caregivers look after these individuals. AD is the sixth leading cause of death, but the only one in the top 10 causes that cannot be prevented.

This study may demonstrate exercise in an amount attainable by many will be preventative in asymptomatic individuals including those with brain Abeta deposition already that are at impending risk of the disease. Sperling and colleagues(1) coined the research term AD-pathophysiological process (abbreviated AD-P) for use in studies such as the intervention in this proposal.

Our long term goal is to assess whether ...

An urgent need exists to find effective treatments for Alzheimer's disease (AD) that can arrest or reverse the disease at its earliest stages. The emotional and financial burden of AD to patients, family members, and society is enormous, and is predicted to grow exponentially as the median population age increases. Current FDA-approved therapies are modestly effective at best. This study will examine a novel therapeutic approach using intranasal insulin (INI) that has shown promise in short-term clinical trials. If successful, information gained from the study has the potential to move INI forward rapidly as a therapy for AD. The study ...

A brain PET scan is recognized as "reasonable and necessary" for some patients with "a recently established diagnosis of dementia" (Centers for Medicare and Medicaid Services, Decision Memo CAG-00088R, 2004), but evidence is less clear for patients having less severe cognitive problems. A substantial portion of such patients will develop Alzheimer's disease and other forms of dementia, which affect millions of people in the U.S., costing us over $100 billion annually. This project employs a prospective randomized protocol to determine whether PET scanning can help distinguish those patients with early Alzheimer's changes in their brains from those having other causes ...

The purpose of this study is to assess the long-term safety and tolerability of ABBV-8E12 in subjects with early Alzheimer's disease (AD).

There is evidence that neurodegenerative changes precede clinical symptoms in Alzheimer’s disease by two decades (Villemagne et al, 2013). Early detection is critical for development of interventions to halt, slow, or even reverse these pathological processes. The promise of plasma biomarkers to identify early pathology is growing rapidly (Palmqvist et al, 2020), however it is likely that multiple converging biomarkers will be necessary to identify the earliest pathological changes, as subtle differences from healthy controls may fall within the margin of error for any given single biomarker measure. Here we propose that the evaluation of speech and language for both ...

Participants not willing to go to the OLE will participate in a long term follow-up period for up to 50 weeks ...

Automobile driving is a crucial aspect of everyday life, but driving safety problems including car crashes or speeding violations are a serious public health problem. Alzheimer’s Disease (AD) affects the ability to safely drive and raises crash risk. Mild cognitive impairment (MCI) raises the risk of dementia, and people with MCI have been shown to have problems with memory, decision making, and the ability to concentrate that could lead to unsafe driving, even before obvious dementia begins. Whether MCI patients who continue to drive are safe drivers or not is unknown.
