Subjective Cognitive ImpairmentNCT03569319
Tailored Mediterranean Lifestyle Education in Participants With Subjective Cognitive Impairment
A study testing "THINK-MED" resource (baseline) and "THINK-MED" resource (staged) in people with Subjective Cognitive Impairment, run by Queen's University, Belfast at 1 site in United Kingdom.
Trial summary
It is estimated that 30% of Alzheimer's disease cases globally are associated with changeable risk factors, such as diet and physical activity. In particular, a Mediterranean diet (MD) has been associated with reduced risk of cognitive decline and improved brain function. Read more about this study

About this study
Official title: The Development and Pilot Testing of Tailored Mediterranean Lifestyle Education to Encourage Behaviour Change in Participants With Subjective Cognitive Impairment
It is estimated that 30% of Alzheimer's disease cases globally are associated with changeable risk factors, such as diet and physical activity. In particular, a Mediterranean diet (MD) has been associated with reduced risk of cognitive decline and improved brain function.
The investigators developed educational resources on the Mediterranean diet and lifestyle (THINK-MED) in accordance with the Medical Research Council guidance for developing and evaluating complex interventions, based on a systematic literature review and informed by qualitative work with patients with mild memory problems.The feedback gathered informed refinements and tailoring of the resource and overall MD intervention.
This study aims to evaluate feasibility of the "THINK-MED" Mediterranean lifestyle educational intervention to encourage dietary behaviour change among community-dwelling people with subjective cognitive impairment.
Read the detailed description
This pilot RCT aims to evaluate the feasibility of a theory-based, tailored Mediterranean lifestyle education intervention (THINK-MED) to encourage behaviour change among participants who have subjective cognitive impairment.
This study will be a 6 month randomised controlled trial (RCT) with a total of 30 participants who will be randomised to 1 of 3 groups:
- Group 1 will receive the "THINK-MED" Mediterranean Lifestyle Education for Memory resource on one occasion at baseline (n=10)
- Group 2 will receive the "THINK-MED" Mediterranean Lifestyle Education for Memory resource at monthly intervals for 5 months, with an initial face-to-face visit from the research dietitian (month 1) and accompanied by telephone feedback (month 2-5) (n=10)
- Group 3 is a control group. Participants in this group will receive the "THINK-MED" Mediterranean Lifestyle Education for Memory resource after completing the 6 month study (n=10)

Questions about this trial
What is this clinical trial studying?
A study testing "THINK-MED" resource (baseline) and "THINK-MED" resource (staged) in people with Subjective Cognitive Impairment, run by Queen's University, Belfast at 1 site in United Kingdom.
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 10 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 3 Apr 2024. 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 Kingdom. 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?
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?
Change in Mediterranean Diet Score (MDS) at 6 months (time frame: Baseline, 6 months). 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 NCT03569319, 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 3 Apr 2024.
