Can stress increase the risk of multiple sclerosis?

31.05.2011
Contrary to earlier reports, a new study finds that stress does not appear to increase a person's risk of developing multiple sclerosis (MS). The research is published in the May 31, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology.

"While we've known that stressful life events have been shown to increase the risk of MS episodes, we weren't certain whether these stressors could actually lead to developing the disease itself," said study author Trond Riise, PhD, with the University of Bergen in Bergen, Norway.

Researchers studied two groups of women nurses from the Nurses' Health Study. The first group of 121,700 nurses between the ages of 30 and 55 were followed starting in 1976. The second group of 116,671 nurses between the ages of 25 and 42 were followed from 1989. Participants were asked to report general stress at home and at work, including physical and sexual abuse in childhood and as teenagers. Of the first group, 77 people developed MS by 2005. In the second group, 292 people developed the disease by 2004. "The risk of MS is particularly high among young women, and the difference in the number of cases is consistent with the different ages of women in the two groups at the beginning of the MS follow-up," said Riise.

After considering factors such as age, ethnicity, latitude of birth, body mass at age 18 and smoking, the study found that severe stress at home did not increase the risk of developing MS. There was also no significant increased risk in developing MS among those who reported severe physical or sexual abuse during childhood or adolescence.

"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, who conducted the research as a visiting scholar at the Harvard School of Public Health.

The study was supported by the National Institute of Neurological Disorders and Stroke.

The American Academy of Neurology, an association of more than 24,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer's disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson's disease and epilepsy.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
