Stress at workplace may increase risk of stroke

Tue, 13 Jan 2009 05:51:42 GMT

(image) Japanese men in high-stress jobs appear to have an increased risk of stroke compared with those in less demanding positions, as per a report in the January 12 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. Stress is considered a risk factor for stroke, as per background information in the article. Several models of job stress have been developed and provide clues as to how occupational factors appears to be modified to reduce risk. "The job demandcontrol model is the most often used occupational stress model," the authors write. "It posits that workers who face high psychological demands in their occupation and have little control over their work (i.e., those who have job strain) are at a greater risk of becoming ill than are workers with low psychological demands and a high degree of control in their occupation (i.e., those with low-strain occupations)"........

Diabetes dementia and brain injuries

Tue, 13 Jan 2009 05:51:42 GMT

(image) Patients with dementia and diabetes appear to display a different pattern of injuries in their brains than patients with dementia but without diabetes, as per an article posted online today that will appear in the March print issue of Archives of Neurology, one of the JAMA/Archives journals. "The association between diabetes mellitus and increased risk for dementia in the elderly is well documented," the authors write as background information in the article. Several possible mechanisms have been proposed for this association, including the direct effects of high blood glucose and insulin, the build-up of beta-amyloid plaques in the brain and the effects of diabetes-related vascular disease on blood vessels in the brain........

A switchboard in the brain helps us learn and remember

Tue, 13 Jan 2009 05:51:42 GMT

(image) The healthy brain is in a constant struggle between learning new experiences and remembering old experiences, a newly released study in this week's PLoS Biology reports. Virtually all social interactions require the rapid exchange of new and old information. For instance, normal conversation requires that while listening to the new information another person is providing, we are already retrieving information in preparation of an appropriate reply. Yet, some memory theories assume that these different modes of memory cannot happen at the same time and compete for priority within our brain........

Where am I?

Tue, 13 Jan 2009 05:51:42 GMT

(image) We've all experienced the feeling of not knowing where we are. Being disoriented is not pleasant, and it can even be scary, but luckily for most of us, this sensation is temporary. The brain employs many tricks to reorient us, keeping our confusion to a minimum and quickly pointing us in the right direction. Research has suggested that animals and young children mainly rely on geometric cues (e.g. lengths, distances, angles) to help them get reoriented. Human adults, however, can also make use of feature cues (e.g. color, texture, landmarks) in their surrounding area. But which method do we use more often? Psychology experts Kristin R. Ratliff from the University of Chicago and Nora S. Newcombe from Temple University conducted a set of experiments investigating if human adults have a preference for using geometric or feature cues to become reoriented........

Alzheimer's patients who are taking antipsychotic drugs

Tue, 13 Jan 2009 05:51:42 GMT

(image) The study, funded by the Alzheimer's Research Trust, was led by Prof Clive Ballard's King's College London team and is published in Lancet Neurology on 9 January. The study involved 165 Alzheimer's patients in care homes who were being prescribed antipsychotics. 83 continued therapy and the remaining 82 had it withdrawn and were instead given oral placebos........

Seeing brain aging before symptoms appear

Tue, 13 Jan 2009 05:51:42 GMT

(image) UCLA researchers have used innovative brain-scan technology developed at UCLA, along with patient-specific information on Alzheimer's disease risk, to help diagnose brain aging, often before symptoms appear. Reported in the recent issue of Archives of General Psychiatry, their study may offer a more accurate method for tracking brain aging........

Smoking and family history of stroke

Tue, 13 Jan 2009 05:51:42 GMT

(image) A newly released study shows that people who are smokers and have a family history of brain aneurysm appear to be significantly more likely to suffer a stroke from a brain aneurysm themselves. The research is reported in the December 31, 2008, online issue of Neurology, the medical journal of the American Academy of Neurology and will appear in the January 6, 2009, print issue of Neurology.......

Use your unconscious brain to make the best bets

Tue, 13 Jan 2009 05:51:42 GMT

(image) Scientists at the University of Rochester have shown that the human brainonce believed to be a seriously flawed decision makeris actually hard-wired to allow us to make the best decisions possible with the information we are given. The findings appear in today's issue of the journal Neuron Neuroresearchers Daniel Kahneman and Amos Tversky received a 2002 Nobel Prize for their 1979 research that argued humans rarely make rational decisions. Since then, this has become conventional wisdom among cognition researchers........

What triggers Alzheimer's disease?

Tue, 13 Jan 2009 05:51:42 GMT

(image) A slow, chronic starvation of the brain as we age may be a main triggers of a biochemical process that causes some forms of Alzheimer's disease. A newly released study from Northwestern University's Feinberg School of Medicine has found when the brain doesn't get enough sugar glucose -- as might occur when cardiovascular disease restricts blood flow in arteries to the brain -- a process is launched that ultimately produces the sticky clumps of protein that appear to be a cause of Alzheimer's........

Role of cardiovascular proteins in Alzheimer's

Tue, 13 Jan 2009 05:51:42 GMT

(image) Scientists have observed that two proteins which work in tandem in the brain's blood vessels present a double whammy in Alzheimer's disease. Not only do the proteins lessen blood flow in the brain, but they also reduce the rate at which the brain is able to remove amyloid beta, the protein that builds up in toxic quantities in the brains of patients with the disease........

Girls have superior sense of taste to boys

Tue, 13 Jan 2009 05:51:42 GMT

(image) Girls have a better sense of taste than boys. Every third child of school age prefers soft drinks which are not sweet. Children and young people love fish and do not think of themselves as being fussy eaters. Boys have a sweeter tooth than girls. Teenagers taste differently. And finally, schoolchildren in northern Denmark have the best taste buds........

A fading sense of smell may signal Parkinson's disease

Tue, 13 Jan 2009 05:51:42 GMT

(image) A number of individuals with Parkinson's disease are able to recall losing their sense of smell well before the onset of more usually recognized symptoms such as tremors, impaired dexterity, speech problems, memory loss and decreased cognitive ability. To determine if a fading sense of smell may signal Parkinson's, scientists at Northwestern Memorial Hospital and Northwestern University's Feinberg School of Medicine are participating in a national study to examine the correlation and ascertain whether smell loss presents a tool for early detection of the disease and an opportunity to delay or ultimately prevent more troublesome symptoms........

If MRI shows signs of MS, will the disease develop?

Tue, 13 Jan 2009 05:51:42 GMT

(image) With more and more people having brain MRIs for various reasons, doctors are finding people whose scans show signs of multiple sclerosis (MS) even though they have no symptoms of the disease. A new study reported in the December 10, 2008, online issue of Neurology, the medical journal of the American Academy of Neurology, observed that a third of these people developed MS within an average of about five years........

Strategic video game improves critical cognitive skills

Tue, 13 Jan 2009 05:51:42 GMT

(image) A desire to rule the world may be a good thing if you're over 60 and worried about losing your mental faculties. A new study observed that adults in their 60s and 70s can improve many cognitive functions by playing a strategic video game that rewards nation-building and territorial expansion. This is the first such study of elderly adults, and it is the first to find such pronounced effects on cognitive skills not directly correlation to the skills learned in the video game, said University of Illinois psychology professor Arthur Kramer, an author on the study........

Maintaining the brain's wiring in aging and disease

Tue, 13 Jan 2009 05:51:42 GMT

(image) Scientists at the Babraham Institute near Cambridge, supported by the Alzheimer's Research Trust and the Biotechnology and Biological Sciences Research Council (BBSRC), have discovered that the brain's circuitry survives longer than previously thought in diseases of ageing such as Alzheimer's disease. The findings were published recently in the journal Brain.......
