MS cognitive status is adversely affected by warmer weather - study
Kessler Foundation scientists correlated functional magnetic resonance imaging (fMRI) findings with the negative impact of outdoor temperature on cognitive functioning in multiple sclerosis (MS).
This study, "Warmer outdoor temperature is associated with task-related increased BOLD activation in patients with multiple sclerosis," released by Brain Imaging & Behavior corroborates the group's previous study that established that people with MS performed worse on processing speed and memory tasks during warmer outdoor temperatures versus during cooler outdoor temperatures. "Increased MS disease activity during warmer months is a recent discovery. Now, this work is the first report of brain activation associated with outdoor temperature in MS. This finding is novel and important for persons with MS who are shown to have worse cognition during warmer weather," said Victoria M. Leavitt, Ph.D., research scientist at Kessler Foundation and principal investigator for the study, funded by a grant from the National MS Society........ Read More - http://www.ms-uk.org/cognition
