Research indicating that stress could cause multiple sclerosis (MS) may be incorrect, a new study has shown.
Scientists from the University of Bergen found that a higher level of stress does not increase the individual's risk of developing MS, according to research published in journal Neurology.
Two groups of female nurses were surveyed in terms of general stress at home and work as well as highly stressful events in the past. There was found to be no association between stress levels and incidence of MS.
Study author Trond Riise explained that while stressful life events are thought to increase the chance of MS episodes, researchers were unsure as to whether such stress could lead to the development of the condition itself.
"This rules out stress as a major risk factor for MS. Future research can now focus on repeated and more fine-tuned measures of stress," said Riise of the results.
Meanwhile, research published in journal Acta Neuropathologica found that Viagra can lessen the symptoms of MS.
