The Comparative Effectiveness Dementia & Alzheimer's Registry (CEDAR)

March 26, 2026 updated by: Weill Medical College of Cornell University
To evaluate the effectiveness of using clinical precision medicine to develop lifecourse interventions for Alzheimer's disease (AD) prevention and treatment. Anthropometrics, blood biomarkers (including genetics), and cognition will measured longitudinally to assess the comparative effectiveness of clinical care.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Enrolling by invitation

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The Comparative Effectiveness Dementia & Alzheimer's Registry (CEDAR) Project is a prospective, observational registry of adult patients at-risk for, or with, a diagnosis of dementia due to Alzheimer's disease (AD) or other neurodegenerative dementias. The purpose of this study is to develop a research repository, or database, for information collected during routine medical care of people with normal memory and family history of AD, or with memory loss or other changes in thinking. The registry will help generate empirical evidence that improves knowledge and informs care decisions about risk reduction for dementia due to AD, and about the effectiveness of a clinical precision medicine intervention. Using a life course approach to comparative effectiveness research will enable investigators to analyze the effects of evidence-based multidomain interventions on cognition, biomarkers of AD risk, and calculated AD risk across the pre-dementia spectrum of AD.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Male and female patients will be recruited at the Alzheimer's Prevention Clinic, Weill Cornell Medicine Memory Disorders Program.

Description

Inclusion Criteria:

  • 18 years of age or older
  • family history of Alzheimer's disease and no cognitive complaints OR subjective cognitive decline OR preclinical AD OR mild cognitive impairment due to AD or other conditions

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in Alzheimer's Prevention Initiative Cognitive Composite (APCC) every 6 months
Time Frame: every 6 months, for 18 months
Composite Cognitive Battery (including NIH Toolbox Cognition Battery and other pen-and-paper neuropsychological tests).
every 6 months, for 18 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in Cognitive Aging Composite (CAC) every 6 months
Time Frame: every 6 months, for 18 months
