Researchers find salt intake, MS link


Following two sets of patients with relapsing-remitting multiple sclerosis, researchers found a link between MS and salt intake. They discovered that higher salt consumption is linked to increased disease activity in patients with MS.

The researchers, led by Dr. Mauricio F Farez, Department of Neurology, Raúl Carrea Institute for Neurological Research, investigated the relationship between salt consumption and clinical and radiological disease activity in MS. They observed the sodium intake of a group of 70 relapsing-remitting patients with MS for 2 years. They then replicated their findings in a separate group of 52 patients with MS.

They found a positive correlation between exacerbation rates and sodium intake. Patients with medium or high sodium intakes had a higher exacerbation rate than the low-intake group. Additionally, patients with greater sodium intake had a higher chance of developing a new lesion on the MRI. A similar relationship was found in the independent replication group.

The study was published in the August issue of the Journal of Neurology, Neurosurgery & Psychiatry.
