Study: Stroke becoming more common in young people

2012-10-11
(Press-News.org) MINNEAPOLIS – New research reveals that stroke may be affecting people at a younger age. The study is published in the October 10, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

"The reasons for this trend could be a rise in risk factors such as diabetes, obesity and high cholesterol," said study author Brett Kissela, MD, MS, with the University of Cincinnati College of Medicine in Ohio and a Fellow of the American Academy of Neurology. "Other factors, such as improved diagnosis through the increased use of MRI imaging may also be contributing. Regardless, the rising trend found in our study is of great concern for public health because strokes in younger people translate to greater lifetime disability."

For the study, researchers looked at occurrences of strokes in people between the ages 20 and 54 in the Greater Cincinnati/Northern Kentucky area during three separate, one year-long periods between July of 1993 and June of 1994, and the calendar years of 1999 and 2005. Only first ever strokes were included in the analysis.

The study found that the average age of people who experienced stroke fell from 71 years in 1993 and 1994 to 69 years in 2005. In addition, the study found that strokes among people under 55 made up a greater percentage of all strokes over time, growing from about 13 percent in 1993-94 to 19 percent in 2005. The stroke rate in young people increased in both African-Americans and Caucasians, from 83 strokes per 100,000 people in 1993-94 in African-Americans to 128 per 100,000 in 2005 and in Caucasians from 26 strokes per 100,000 people in 1993-94 to 48 per 100,000 in 2005.

"The good news is that some of the possible contributing factors to these strokes can be modified with lifestyle changes, such as diet and exercise," said Kissela. "However, given the increase in stroke among those younger than 55, younger adults should see a doctor regularly to monitor their overall health and risk for stroke and heart disease."

Women react to and recollect negative news more than men do

2012-10-11
Women who read negative news remember it better than men do, and have stronger stress responses in subsequent stress tests, according to new research published Oct 10 in the open access journal PLOS ONE by Sonia Lupien and colleagues from the University of Montreal, Canada. The researchers exposed groups of men and women to a succession of headlines drawn from recent newspaper articles. One group viewed only 'neutral' news, while the other group was shown news perceived as 'negative'. After reading the news, participants performed a standard psychological stress test. ...

New fossils suggest ancient origins of modern-day deep-sea animals

New fossils suggest ancient origins of modern-day deep-sea animals
2012-10-11
A collection of fossil animals discovered off the coast of Florida suggests that present day deep-sea fauna like sea urchins, starfish and sea cucumbers may have evolved earlier than previously believed and survived periods of mass extinctions similar to those that wiped out the dinosaurs. The full results are published Oct. 10 in the open access journal PLOS ONE by Ben Thuy and colleagues from the University of Göttingen, Germany. Previously, researchers believed that these present-day animals evolved in the relatively recent past, following at least two periods of mass ...

Single spider dads caring for eggs suffer no disadvantages despite parenting costs

Single spider dads caring for eggs suffer no disadvantages despite parenting costs
2012-10-11
Single fatherhood is a challenge many arachnids undertake, guarding eggs laid by females despite the costs to their own health and mating benefits, but the news may not be all bad for these dads. New research now shows that, in one species of spiders, males exclusively responsible for guarding eggs actually enjoy survival benefits rather than suffer losses to health or mating privileges. The study, published Oct. 10 in the open access journal PLOS ONE by Gustavo Santos Requena and colleagues from the University of Sao Paulo, Brazil, evaluates the costs and benefits ...

Skin hair skims heat off elephants

Skin hair skims heat off elephants
2012-10-11
Body hair in mammals is typically thought to have evolved to keep us warm in colder prehistoric times, but a new study suggests that it may do the opposite, at least in elephants. Epidermal hair may have evolved to help the animals keep cool in the hot regions they live in, according to new research published Oct 10 in the open access journal PLOS ONE by Conor Myhrvold and colleagues at Princeton University. Though the idea that low surface densities of hair can help dissipate heat is a popular concept in engineering, the biological and evolutionary significance of sparse ...

Parent-clinician communication about children's drug reactions needs improvement

2012-10-11
Many parents are dissatisfied with communication regarding adverse drug reactions experienced by their child, and the implications of such reactions for the child's future use of medicines, according to a new study published Oct. 10 in the open access journal PLOS ONE by Bridget Young from the University of Liverpool, UK and colleagues. The researchers interviewed parents of 44 children who had a suspected adverse drug reaction for their study. They found that the majority of parents in their study were dissatisfied with the clarity and timing of communications from ...

Like songbirds and people, mice can learn new tunes

2012-10-11
AUDIO: This is a mouse song. Click here for more information. Scientists have found the first evidence that the ability to learn vocalizations, a capacity so far believed to be restricted to a handful of bird and mammal species like humans and dolphins, is shared by another species: mice. The new research, published Oct. 10 in the open access journal PLOS ONE by Erich Jarvis and Gustavo Arriaga at Duke University and colleagues, shows for the first time that mice share certain ...

Negative news stories affect women's stress levels but not men's

2012-10-11
Bad news articles in the media increase women's sensitivity to stressful situations, but do not have a similar effect on men, according to a study undertaken by University of Montreal researchers at the Centre for Studies on Human Stress of Louis-H. Lafontaine Hospital. The findings were published today in PLOS One. The women who participated in the study also had a clearer recollection of the information they had learned. "It's difficult to avoid the news, considering the multitude of news sources out there, said lead author Marie-France Marin. "And what if all that news ...

Cambrian fossil pushes back evolution of complex brains

Cambrian fossil pushes back evolution of complex brains
2012-10-11
The remarkably well-preserved fossil of an extinct arthropod shows that anatomically complex brains evolved earlier than previously thought and have changed little over the course of evolution. According to University of Arizona neurobiologist Nicholas Strausfeld, who co-authored the study describing the specimen, the fossil is the earliest known to show a brain. The discovery will be published in the Oct. 11 issue of the journal Nature. Embedded in mudstones deposited during the Cambrian period 520 million years ago in what today is the Yunnan Province in China, the ...

NIH researchers provide detailed view of brain protein structure

2012-10-11
Researchers have published the first highly detailed description of how neurotensin, a neuropeptide hormone which modulates nerve cell activity in the brain, interacts with its receptor. Their results suggest that neuropeptide hormones use a novel binding mechanism to activate a class of receptors called G-protein coupled receptors (GPCRs). "The knowledge of how the peptide binds to its receptor should help scientists design better drugs," said Dr. Reinhard Grisshammer, a scientist at the NIH's National Institute of Neurological Disorders and Stroke (NINDS) and an ...

Glaciers cracking in the presence of carbon dioxide

2012-10-11
The well-documented presence of excessive levels of carbon dioxide (CO2) in our atmosphere is causing global temperatures to rise and glaciers and ice caps to melt. New research, published today, 11 October, in IOP Publishing's Journal of Physics D: Applied Physics, has shown that CO2 molecules may be having a more direct impact on the ice that covers our planet. Researchers from the Massachusetts Institute for Technology have shown that the material strength and fracture toughness of ice are decreased significantly under increasing concentrations of CO2 molecules, ...
