Study summary

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.

Read the 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.

What researchers measure

Primary outcomes

  1. Change from Baseline in Alzheimer's Prevention Initiative Cognitive Composite (APCC) every 6 months

    Composite Cognitive Battery (including NIH Toolbox Cognition Battery and other pen-and-paper neuropsychological tests).

    Time frame: every 6 months, for 18 months

Secondary outcomes

  1. Change from Baseline in Cognitive Aging Composite (CAC) every 6 months

    Composite Cognitive Battery, including neuropsychological tests related to non-pathological (age-related) cognitive decline.

    Time frame: every 6 months, for 18 months

  2. Change from Baseline of Australian National University - Alzheimer's Disease Risk Score (ANU-ADRI) at 6 months

    Measure longitudinal changes in a validated Alzheimer's risk scale (score range from -13 to 78) where higher scores confer higher risk

    Time frame: 6 months

  3. Change in Baseline on Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE) Risk Score at 18 months

    Measure longitudinal changes in a validated Alzheimer's risk scale (score range from 0 to 14) where higher scores confer higher risk

    Time frame: 18 months

  4. Change from Baseline on American College of Cardiology / American Heart Association Cardiovascular Risk Percentage at 18 months

    Measure longitudinal changes in a validated cardiovascular risk scale (higher percentage confers higher risk).

    Time frame: 18 months

  5. Change from Baseline on Multi-Ethnic Study of Atherosclerosis (MESA) Risk Percentage at 18 months.

    Measure longitudinal changes in a validated cardiovascular risk scale (higher percentage confers higher risk).

    Time frame: 18 months

  6. Change from Baseline in Cholesterol Biomarkers at 18 months

    Change in blood serum levels of cholesterol (total, LDL, HDL) in mg/dL

    Time frame: 18 months

  7. Change from Baseline in Inflammatory Biomarkers at 18 months

    Change in blood serum levels of hs-CRP, fibrinogen, Cystatin C in mg/dL

    Time frame: 18 months

  8. Change from Baseline in Metabolism Biomarkers at 18 months

    Change in blood serum levels of HbA1c and HOMA-IR

    Time frame: 18 months

  9. Change from Baseline in Homocysteine at 18 months

    Change in blood serum level of homocysteine

    Time frame: 18 months

  10. Change from Baseline in Vitamin D at 18 months

    Change in blood serum level of Vitamin D

    Time frame: 18 months
