The relationship between vitamin D levels and cognitive impairment in patients with multiple sclerosis.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in the context of multiple sclerosis in this observational study publication.

Neurocognitive impairment is one of the most common manifestations of multiple sclerosis (MS).

However, the pathophysiology of this issue is still poorly understood.

The objective of this study is to investigate the relationship between vitamin D levels and cognitive function in patients with MS as assessed by the Cambridge Neuropsychological Test Automated Battery (CANTAB).

Who Took Part

According to the abstract, 39 patients were involved.

PubMed indexes the participants as teenagers, young adults, adults and middle-aged adults, both men and women.

This was a cross-sectional, case-control study; the subjects were 39 Saudi patients diagnosed with MS.

For all participants, demographic information, including age, sex, and educational level, was collected.

How the Study Was Run

Participants were also evaluated using the disease steps scale and the PHQ-9 scale.

Their vitamin D levels were assessed, and the participants completed a computerized cognitive assessment using the CANTAB.

What Was Measured

Topics PubMed links to this paper include Cognitive Dysfunction, Cross-Sectional Studies, Multiple Sclerosis and Vitamin D.

What This Means in Plain Language

This is an observational study of Vitamin D, K2, Magnesium and Zinc in 39 patients in people with multiple sclerosis.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The abstract goes on to report its results in about 11 sentences; this page does not restate them, so read the paper for the findings and their limits.

The publication is from 2021 (European review for medical and pharmacological sciences), a journal based in United States.
