Past Pregnancies Linked to Reduced MS Risk in Women

09.03.2012
Women who have multiple pregnancies may have a lower risk of developing multiple sclerosis (MS), according to research published in the March 7, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

“In our study, the risk went down with each pregnancy and the benefit was permanent,” said study author Anne-Louise Ponsonby, PhD, of Murdoch Children’s Research Institute in Melbourne, Australia.

Researchers reviewed information about 282 Australian men and women between the ages of 18 and 59 who had a first diagnosis of central nervous demyelination, which means they had their first symptoms similar to MS but had not yet been diagnosed with the disease. They were compared to 542 men and women with no MS symptoms. For women, the number of pregnancies lasting at least 20 weeks and the number of live births were recorded. For men, the number of children born was recorded.

The study found that women who were pregnant two or more times had a quarter of the risk of developing MS symptoms and women who had five or more pregnancies had one-twentieth the risk of developing symptoms than women who were never pregnant. There was no association between the amount of children and risk of MS symptoms in men.

“The rate of MS cases has been increasing in women over the last few decades, and our research suggests that this may be due to mothers having children later in life and having fewer children than they have in past years,” said Ponsonby.

The study was supported by the National Multiple Sclerosis Society of the United States of America, the National Health and Medical Research Council of Australia and Multiple Sclerosis Research Australia.

The American Academy of Neurology, an association of more than 25,000 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: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
