Brief summary

This is an open label feasibility trial to examine the effect of a complementary treatment with High Phenolic Extra Virgin Olive Oil (HPEVOO) on the cognitive and mental health of people with Multiple Sclerosis (MS), while receiving their standard medical treatment.

Interventions

DIETARY_SUPPLEMENTHigh Phenolic Extra Virgin Olive Oil

Participants will be assigned in two groups: the Experimental Group (N= 20) will be receiving 50ml of freshly, cold-pressed, oleocanthal-rich Extra Virgin Olive Oil (EVOO) alongside their prescribed medical treatment, whereas the Control Group (N = 20) will be receiving their medical treatment as usual. The Experimental Group will be receiving the complementary treatment on a daily basis for 12 months and all participants will undergo a neuropsychological assessment at baseline, 6 months and 12 months +/- 7 days after their first assessment or beginning of treatment.

Design outcomes

Primary

MeasureTime frameDescription
Symbol Digits Modalities Test (SDMT)baseline, 6-months, 12-monthsChange will be assessed in the SDMT score (0-100 range), over three time points. Higher score indicates better processing speed.
California Verbal Learning Test-Second Edition (CVLT-II)baseline, 6-months, 12-monthsChange will be assessed in the CVLT-II score (0-80 range), over three time points. Higher score indicates better auditory-verbal learning.
Brief Visuospatial Memory Test-Revised (BVMT-R)baseline, 6-months, 12-monthsChange will be assessed in the BVMT-R score (0-36 range), over three time points. Higher score indicates better visuospatial memory.
Wisconsin Card Sorting Test (WCST)baseline, 6-months, 12-monthsChange will be assessed in the WCST score over three time points. WCST examines attention, working memory and intellectual flexibility (0-64 score range). Higher scores represent worse performance.
Trail Making Test (TMT)baseline, 6-months, 12-monthsChange will be assessed in the TMT scores over three time points. TMT examines attention, intellectual flexibility and inhibition. Longer time to completion indicates worse performance.
The Vocabulary and Block Design from the Wechsler Adult Intelligence Scale (WAIS)baselineIt will provide an estimated intelligence quotient (IQ) score
The Digit Span Test (DST) from WAISbaseline, 6-months, 12-monthsChange will be assessed in the DST score over three time points. DST examines working memory, 0-48 score range, higher scores indicate better working memory function.
Word List Generation (WLG) Testbaseline, 6-months, 12-monthsChange will be assessed in the WLG score over three time points. WLG examines lexical fluency. The higher the number of words generated, the better is the performance.
Faux Pas Recognition (FPR) Testbaseline, 6-months, 12-monthsChange will be assessed in the FPR score over three time points. FPR examines social cognition. Four different vignettes will be used for every assessment (0-20 score range). Higher scores indicate better performance.
Hospital Anxiety and Depression Scale (HADS)baseline, 6-months, 12-monthsChange will be assessed in the HADS scores over three time points. HADS examines anxiety, depression and psychological distress. Higher scores (0-42 range) indicate greater levels of anxiety and depression.
Health Status Questionnaire (SF-36)baseline, 6-months, 12-monthsChange will be assessed in SF-36 scores over three time points. SF-36 consists of eight scales (0-100 score range each) that examine physical and mental health-related quality of life. The lower the score the more disability.
Modified Fatigue Impact Scale (MFIS)baseline, 6-months, 12-monthsChange will be assessed in the MFIS score over three time points. MFIS examines how often fatigue interferes with daily activities. Higher scores (0-84 score range) indicate greater impact of fatigue on a person's activities.
