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.

  • Age between 55 and 90 (inclusive)
  • Score on the Montreal Cognitive Assessment (MOCA) 15 to 23
  • Presence of a responsible caregiver who will accompany mild cognitive impaired (MCI) subjects to all procedures.

Previous treatment with an investigational small molecule with anti-amyloid properties or passive immunization against amyloid within 1 year of study entry. Previous treatment with an active immunization against amyloid.
  • History of schizophrenia or other major psychiatric disorder (DSM IV criteria).
  • History of alcohol or substance abuse or dependence (DSM IV criteria) within the past 2 years.

  • Education level < 6 years.
  • Presence of pacemakers, aneurysm clips, artificial heart valves, ear implants, metal fragments or foreign objects in the eyes, skin or body. The presence of claustrophobia, precluding MRI.
  • Drink more than 5 alcoholic drinks per week or any heavy drinking days in the last 30 days
  • Women who are pregnant or nursing, or fail to use one of the following methods of birth control unless she or partner is surgically sterile or she is postmenopausal (hormone contraceptives [oral, implant, injection, patch, or ring], contraceptive sponge, double barrier [diaphragm or condom plus spermicide], or intrauterine device (IUD)

About this study

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.

Read the 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.

Being tested
MRI including cf-MRI, DTI, ASL and CVR.
Medical subject headings
Diabetic Angiopathies

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MRI including cf-MRI, DTI, ASL and CVR.Diagnostic test

    Also called Neuropsychological testing (Cantab), basic laboratory blood tests, small number of CSF

    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.

Study groups in NCT03754608
Study groupRoleWhat they receive
Diabetics/No cognitive impairmentThese are individuals with diabetes who do not have vascular cognitive impairment as determined by VASCOG criteria.
Receives: Diagnostic Test: MRI including cf-MRI, DTI, ASL and CVR.
Diabetics with vascular cognitive impairmentThese are individuals with diabetes who have vascular cognitive impairment as determined by VASCOG criteria.
Receives: Diagnostic Test: MRI including cf-MRI, DTI, ASL and CVR.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Diagnostic Odds ratio for the MRI vascular cognitive impairment biomarker.

    This will be calculated from the sensitivity and specificity as compared to clinical diagnosis.

    Measured: 2 years

Secondary outcomes (1)
  1. Correlation between the biomarker and cognition

    Assess whether the biomarker can predict the severity of the cognitive performance.

    Measured: 18 months.

Questions about this trial

What is this clinical trial studying?

An observational study of Small Vessel Disease of Diabetes Mellitus, run by Yale University 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 15 inclusion and 12 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: finished, as of the sponsor's last update on 19 Apr 2021. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Diagnostic Odds ratio for the MRI vascular cognitive impairment biomarker. (time frame: 2 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 19 Apr 2021.
