About this study

Official title: Oriental Intervention for Enhanced Neurocognitive Health (Orient) Diet in Populations With High Risk of Stroke (ENDS): a Randomized Controlled Trial

This randomized controlled trial will enroll 160 individuals aged over 40 without dementia who are at high risk of stroke, collecting multi-modal MRI imaging, serum, and fecal samples to investigate the impact of the ORIENT diet on brain functional networks.

Read the detailed description

Oriental Intervention for Enhanced Neurocognitive Health (ORIENT) Diet in Populations with High Risk of Stroke is designed to test the impact of a 6-month intervention utilizing a culturally adapted version of the MIND diet, named as the ORIENT diet, on 160 participants (aged 40 years and above, and without dementia) with high risk of stroke (defined as having transient ischemic attack or having ≥ 3 stroke risk factors including hypertension, dyslipidemia, diabetes, atrial fibrillation or valvular heart disease, smoking history, obvious overweight or obesity, lack of exercise, family history of stroke). The ORIENT diet retains the core components of the DASH, Mediterranean, and MIND diets, but incorporates adjustments according to evidence derived from Asian prospective cohorts and Chinese dietary practices. Participants in the intervention group will receive the ORIENT diet intervention, while participants in the control group will receive standard low-sodium and low-fat dietary advice. The study's primary objective is to assess the impact of the ORIENT diet on the brain functional networks of individual with high risk of stroke. The investigation will explore potential mediators and modifiers of the intervention's effects by collecting various cardiovascular risk factors, serum samples, fecal samples, neuropsychological assessment results, and multi-modal magnetic resonance imaging at baseline, 6 months, and 2 years.

Questions about this trial

What is this clinical trial studying?

A study testing Usual Diet advice and ORIENT diet intervention in people with High Risk of Stroke, run by Second Affiliated Hospital, Zhejiang University, School of Medicine at 1 site in China.

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 5 inclusion and 14 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: looking for participants now, as of the sponsor's last update on 15 Jun 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 China. 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. Some participants in this study may receive a placebo. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Min Lou, PhD, MD (13958007213, lm99@zju.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in brain functional network connectivity assessed by resting state functional magnetic resonance imaging (fMRI) (time frame: 6 months). 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 15 Jun 2025.
