"A stroke is just one rare but bad possible complication of an infection," said Fullerton.
of kids who survive Nike Zoom Elite 6 a stroke will end up with a severe disabling outcome, another third will have an evident problem and a third will have minimal or no deficits, said Fullerton.
The children who had strokes were 12 times more likely to have seen a physician for a minor infection within three days of the stroke than were the children who didn't have strokes. About 80 percent of the minor infections identified were upper respiratory, such as colds and flu.
When strokes occur in kids, the outcomes aren't always good, said Fullerton. "Fatality rates are 5 to 10 percent, so certainly kids can die from strokes."
While it is unclear exactly how the process might work, inflammatory responses which are a defense mechanism against infection can cause a stroke, said Dr. Lars Marquardt, who wrote an editorial accompanying the research, published online Aug. 20 in Neurology.
For the study, researchers tapped a health care plan database of 2.5 million children. From that group, they identified about 100 children who had had an ischemic stroke (the type caused by obstruction of a blood vessel that supplies blood to the brain). They matched those children to about 300 kids who didn't have strokes. Kids who had had a major infection such as meningitis or sepsis were excluded from the study.
Flu to Rare Risk of Stroke in Kids

The study had several limitations, said Marquardt, a professor of surgery in the department of neurology at the University of Erlangen Nuremberg, Germany. The research didn't include children who hadn't seen a physician for their infection. Also, the researchers didn't review laboratory tests to look for signs of infection that might not have been entered into the medical record, and they didn't include analysis of any nonprescription medications the children may have taken that could have prevented blood clots, he noted.

Youth can actually work against children in the case of a stroke. Kids have more brain mass than adults, because older brains tend to shrink a little over time. Since kids' brains are still "full sized," there's less room for the brain swelling that occurs after a stroke, Fullerton explained. "So they die from very high pressures in their head, Nike Zoom Cage 2 Womens
"Infections trigger activation of platelets [blood cells responsible for clotting], making them more prone to clotting," he said.
The study found that the risk of stroke from infection was increased only within a three day period. That suggests that the cause is acute inflammation of the arteries, a problem already discovered as a possible trigger in adults, said Fullerton.
WEDNESDAY, Aug. 20, 2014 (HealthDay News) Although it's extremely rare, colds, flu and other minor infections might trigger a strong but brief period of elevated risk for stroke in children, a new study suggests.
Children with health issues such as cardiac disease, sickle cell anemia or lupus may be more prone to stroke. Yet a small number of children appear to have been perfectly healthy before having a stroke, explained Fullerton.
However, having chronic infections or a series of infections did not seem to increase the risk of stroke. "With kids, once you're done with an infection you're done with the stroke risk," Fullerton explained.
Just five out of 100,000 children a year have a stroke in the United States, said Dr. "It seems infections play a role in causing a stroke in those who are somehow predisposed to the problem," she said.
