Validating Imaging Biomarkers of Small Vessel Disease in Diabetic Individuals Using Advanced MRI Techniques.

April 16, 2021 updated by: Yale University
To develop a set of biomarkers for imaging of small vessel disease in diabetic individuals using advanced MRI techniques. With this the investigators want to document progression of disease both radiologically and clinically.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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 investigators will use a paradigm developed at Yale University called Cognitive Predictive Modelling (CPM) which takes connectivity data and reduces it to two smaller network which predict higher and lower performance in a particular task for which these networks have been optimized. Vascular measures will complement this measure.

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

55 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Our study population are those with type 2 diabetes in mid-life and old age, who may or may not have cognitive deficits, whose cognitive deficits (when present) cannot be better explained by other factors. We exclude those who are unable to have MRI or cognitive testing due to a variety of reasons.

  6. History of alcohol or substance abuse or dependence (DSM IV criteria) within the past 2 years.
  7. Pregnancy, as determined by screening pregnancy tests for pre-menopausal females
  8. Impairment of visual or auditory acuity sufficient to interfere with study procedures.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Diabetics/No cognitive impairment
These are individuals with diabetes who do not have vascular cognitive impairment as determined by VASCOG criteria.
Diagnostic test: MRI including cf-MRI, DTI, ASL and CVR.
A paradigm developed at Yale University called Cognitive Predictive Modelling which takes connectivity data and reduces it to two smaller network which predict higher and lower performance in a particular task for which these networks have been optimized. This will be supplemented by MRI vascular measures.
Other Names:
  • Neuropsychological testing (Cantab), basic laboratory blood tests, small number of CSF

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
Diagnostic Odds ratio for the MRI vascular cognitive impairment biomarker.
Time Frame: 2 years
This will be calculated from the sensitivity and specificity as compared to clinical diagnosis.
2 years

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
Correlation between the biomarker and cognition
Time Frame: 18 months.
Assess whether the biomarker can predict the severity of the cognitive performance.
18 months.
