About this trial
This study will assess the impact of a MIND (Mediterranean-DASH Intervention for Neurodegenerative Delay) diet on brain health and MS symptoms. Participants will be randomly assigned to one of two arms: the diet intervention arm or the "continue current diet"/control arm. Participants randomized to the dietary intervention arm will change their diet to follow a MIND dietary pattern for one year; diet-related education and programming is provided to support this change. Participants randomized to the continue/control arm will be asked to continue their current dietary habits, without major change for one year; multiple sclerosis (MS) MS-related related education and programming (unrelated to diet) is provided. All participants will be asked to provide blood \& stool samples and to complete online questionnaires \& three in-person assessments.

Treatments tested in this trial
Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) Diet
BehavioralA dietary pattern which promotes the intake of olive oil, fish, leafy greens \& other vegetables, fruits, whole grains, and legumes, and discourages processed foods, red meat, and sugar.
Small Group
BehavioralEducation and social support on topics related to multiple sclerosis such as disease-modifying therapies and MRI in MS.

Trial outcomes
Primary outcomes
Changes in plasma neurofilament light chain (NfL)
Plasma NfL quantification will be reported in units of pg/ml.
Secondary outcomes
Neurological Fatigue Index-MS (NFI-MS)
The NFI-MS is a brief (5-10-minute completion time), 23-item survey that measures fatigue in MS. Each question corresponds to a subscale that describes different facets of MS fatigue: physical (range 0-8), cognitive (range 0-4), relief by diurnal sleep or rest (range 0-6), and abnormal nocturnal sleep \& sleepiness (range 0-5). A summary score (range 0-30) can be calculated based on the responses from 10 of the items on the questionnaire. Scores are based on the respondent's level of agreement with each statement (0, Strongly Disagree; 1, Disagree; 2, Agree; 3, Strongly Agree); higher scores indicate higher levels of fatigue.
The Expanded Disability Status Scale (EDSS)
The Expanded Disability Status Scale (EDSS) helps to describe the extent to which one's MS affects their everyday functionality based on a neurological and physical exam. Total scale is scored from 1-10, with a higher score indicating greater levels of disability due to MS.
The Symbol-Digit Modalities Test (SDMT)
The Symbol Digit Modalities Test (SDMT) presents a series of nine symbols, each paired with a single digit in a key at the top of a stimulus page. Subjects voice the number associated with each symbol as rapidly as possible. The examiner records the total amount of responses completed. The task continues for 90 seconds with the research staff recording responses. The SDMT score ranges from 0 to 110, with higher values representing a better outcome in cognitive processing speed.
California Verbal Learning Test (CVLT-II)
The California Verbal Learning Test-Second Edition (CVLT-II) is a widely used neuropsychological assessment designed to evaluate verbal learning and memory. It requires individuals to recall words across multiple trials, measuring encoding, recall strategies, and recognition accuracy. Scores are based on the number of correctly recalled words across different conditions, including immediate free recall, short-delay free \& cued recall, long-delay free \& cued recall. Each trial is scored separately, with higher scores (range 0-16) indicating the successful recall of a word; raw scores are converted to a T-score based on age-and-sex-matched normative data.
