Trial summary

The purpose of this study is to use a functional MRI (fMRI) index to compare the brain activity of healthy volunteers to that of people with mild cognitive impairment (MCI) and Alzheimer's disease. The ultimate goal is to develop an early diagnostic tool for Alzheimer's disease. The study hypotheses are: 1. Read more about this study

About this study

The purpose of this study is to use a functional MRI (fMRI) index to compare the brain activity of healthy volunteers to that of people with mild cognitive impairment (MCI) and Alzheimer's disease. The ultimate goal is to develop an early diagnostic tool for Alzheimer's disease.

The study hypotheses are:

  1. The fMRI index will differentiate between Alzheimer's disease, non-Alzheimer's dementia, and healthy volunteers;
  2. The fMRI index will distinguish participants with MCI who convert to Alzheimer's disease from those who convert to a non-Alzheimer's dementia and those who remain stable;
  3. MCI participants with a lower fMRI index at baseline who convert will progress to Alzheimer's sooner than those with a higher fMRI index, and MCI participants with a faster rate of fMRI index decline who convert will have an earlier onset of Alzheimer's disease.
Read the detailed description

The onset of Alzheimer's disease is insidious and the boundary between normal aging and Alzheimer's disease is blurred. In order to prevent and treat Alzheimer's disease, the investigators must be able to mark its preclinical stage, before brain damage becomes irreversible. There is a substantial body of research dealing with predictive markers of Alzheimer's disease in individuals with mild cognitive impairment (MCI). Despite these advances, however, researchers have not had enough evidence to recommend specific techniques that mark preclinical Alzheimer's disease. This new functional MRI (fMRI) index may fill this gap.

Participants will have two visits, one for memory testing and neurological examination, and one for an MRI scan. Each visit will take approximately 1½ hours. For volunteers who wish to do so, all study procedures may be completed in a single visit. Participants with MCI will be followed annually.

The investigators are currently enrolling healthy volunteers, as well as individuals with MCI (memory loss that does not significantly affect normal daily activities), Alzheimer's disease, and frontotemporal dementia (includes primary progressive aphasia).

Questions about this trial

What is this clinical trial studying?

An observational study of Alzheimer's Disease and Mild Cognitive Impairment, run by Medical College of Wisconsin at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 14 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine the sensitivity and specificity of the MRN Index as an AD biomarker. (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2016.
