A new study suggests that colds and other minor infections may temporarily increase stroke risk in children. The study is published in the August 20, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
“While the study does show an increased risk, the overall risk of stroke among children is still extremely low,” said Lars Marquardt, MD, DPhil, of the University of Erlangen-Nuremberg in Germany, who wrote a corresponding editorial. “Minor infections are very common in children while strokes are thankfully very rare. Parents should not be alarmed whatsoever if a child catches a simple cold.”
For the study, researchers reviewed a Kaiser Permanente database of 2.5 million children. Of those, the scientists identified 102 children who had an ischemic stroke without a major infection associated and compared them with 306 children without stroke.
The children’s medical records were reviewed for minor infections up to two years before the stroke. About 80 percent of the infections were respiratory.
The study found that the risk of stroke was increased only within a three-day time frame between doctors’ visits for signs of infection and stroke. A total of 10 of the 102 children who had a stroke had a doctor visit for an infection within three days of the stroke, or 9.8 percent, while only two of the 306 control participants, or 0.7 percent, had an infection during the same time period.
The children who had strokes were 12 times more likely to have had an infection within the previous three days than the children without strokes. The total number of infections over a two-year period was not associated with increased stroke risk.
“These findings suggest that infection has a strong but short-lived effect on stroke risk,” said study author Heather J. Fullerton, MD, MAS, with UCSF Benioff Children’s Hospital San Francisco. “We’ve seen this increase in stroke risk from infection in adults, but until now, an association has not been studied in children. It is possible that inflammatory conditions contribute more to the stroke risk in children, however, further research is needed to explore this possible association.”
The study was supported by the National Institute of Neurological Disorders and Stroke.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
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...
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...
