About this study

Official title: Arterial Function and Structure and Evolution of Cognitive Impairment in Elderly Hypertensive Subjects With Subjective Memory Complaints

In the cross sectional study "Adelahyde 1" which took place between 2001 and 2005, the investigators data suggest that vascular alterations may play a role in the setting of subjective memory complaints.

This longitudinal study (Adelahyde 2) aims to confirm the role of vascular factors in the evolution of cognitive function and dementia.

Read the detailed description

Background: The role of arterial hypertension and vascular alterations in the development of cognitive decline is a major issue in both research and clinical practice. In a recently published cross-sectional study (Kearney-Schwartz, Rossignol et al. 2009), conducted on the "ADELAHYDE" cohort comprised of older hypertensive patients with memory complaints, the investigators showed the association of arterial changes (hypertrophy and arterial stiffness, endothelial dysfunction) with cognitive functions and/or white matter hyperintensities on MRI. A longitudinal study is the only means to confirm the role of vascular factors in the evolution of cognitive function and onset of dementia.

Objectives: i) Primary: To establish, in the "ADELAHYDE" cohort, the relationship between vascular alterations assessed at baseline during the cross-sectional study (hypertrophy and arterial stiffness, endothelial dysfunction) and the evolution of cognitive function (primary study endpoint) over a 8-year follow-up period; ii) Secondary a) To investigate the evolution of white matter hyperintensities on MRI (secondary study endpoint) as a function of peripheral vascular status, and especially of endothelial function. b) Determine the role of genetic factors and biomarkers of oxidative stress (from DNA and serum biobanks collected at the first visit) in the evolution of cognitive functions and white matter hyperintensities.

Methods: Prospective longitudinal single center study. All patients (378 subjects) who participated in the baseline cross-sectional study conducted between 2001 and 2005, will be reconvened at the Clinical Investigation Centre (CIC) of Nancy.

As in the cross-sectional study, the following will be assessed in this longitudinal phase: pulse wave velocity (PWV), carotid ultrasonography, flow-mediated dilation, brain MRI with semi-quantification of white matter hyperintensities, cognitive function evaluation and measurement of various biomarkers of endothelial function.

Expected fallouts: A major benefit of this project is that this cohort has already been explored in terms of cognitive function, arterial properties and neurovascular imaging (MRI). Thus, the programmed reconvening of these subjects for this project in 2011 will enable us to identify the role of vascular alterations in the evolution of cognitive function and leucoaraiosis in this population at high risk of dementia over a period of at least 8 years. Finally, it could pave the way for further investigations, notably in the field of cognitive impairment prevention, aimed at reducing or delaying the onset of dementia by acting on the "vascular factor", which is potentially modifiable.

Questions about this trial

What is this clinical trial studying?

A study testing blood sampling, brain MRI and TEP cerebral and Assessment of cognitive functions in people with Cognitive Impairment, run by Central Hospital, Nancy, France at 1 site in France.

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 3 inclusion and 1 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 15 Sep 2025. 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 France. 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?

Global memory, visual retention and verbal fluency composite score (time frame: up to two years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01351961, which also lists 1 linked publication.

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 15 Sep 2025.
