Trial outcomes
Primary outcomes
Montreal Cognitive Assessment (MoCA) score
Composite measure of global cognitive function
fMRI
Functional brain activity will be analysed during cognitive tasks.
MRS
MRS will be used to assess neurochemistry of the medial temporal lobe and medial frontal cortex at rest.
Secondary outcomes
Pittsburgh Sleep Quality Index Scores
A validated self-report measure of sleep quality.
Immediate Word Recall from the Rey Auditory Verbal Learning Task
Participants will be presented with a sequential list of 15 words, at a rate of 1 word per second. The participant will then have 60s to say out loud as many of these words as possible, with the resulting score recorded as a percentage of accuracy.
Delayed Word Recall from the Rey Auditory Verbal Learning Task
After a period of time subject are asked to recall as many words as possible from list A
Gastrointestinal Symptom Rating Scale Scores
A validated self-report measure of gastrointestinal symptoms that includes 15-items (combined into five symptom clusters depicting Reflux, Abdominal pain, Indigestion, Diarrhoea and Constipation)
Other outcomes
Telephone Interview for Cognitive Status-40
A questionnaire that assesses cognitive status. It will be used to screen participants.
Gut microbiome diversity
In a random subsample of participants, stool samples will be collected to measure gut microbiome diversity. Indices of alpha and beta diversity will be analysed (16s sequencing).
Gut microbiome composition
In a random subsample of participants, stool samples will be collected to measure gut microbiome composition (genus and species) (16s sequencing).
