Although there were promising results in a phase 2 trial, patients with mild Alzheimer disease who received the drug tarenflurbil as part of a phase 3 trial did not have better outcomes on measures of cognitive decline or loss of activities of daily living compared to patients who received placebo, according to a study in the December 16 issue of JAMA. http://www.physorg.com/news180116942.html Medicine & Health Tue, 15 Dec 2009 16:29:57 EST news180116942 A Kansas State University professor's research is showing a gap between the character traits that business students say make a good executive and the traits they describe having themselves. http://www.physorg.com/news179501607.html Other Sciences Tue, 08 Dec 2009 13:35:57 EST news179501607 Having a tough time recalling a phone number someone spoke a few minutes ago or forgetting items from a mental grocery list is not a sign of mental decline; in fact, it's natural. http://www.physorg.com/news178220995.html Physics Mon, 23 Nov 2009 17:51:01 EST news178220995 In a study that promises to improve diagnosis and monitoring of Alzheimer's disease, scientists at the University of California, San Diego have developed a fast and accurate method for quantifying subtle, sub-regional brain volume loss using magnetic resonance imaging (MRI).

However, there is new hope in the form of new research published October 28 in the open-access, peer-reviewed journal PLoS ONE, which suggests that relocating new bears doesn't just boost the population size but can also reverse some of the causes of the population decline. http://www.physorg.com/news175896460.html Biology Tue, 27 Oct 2009 21:30:03 EST news175896460 ST. PAUL, Minn. -Research has shown that diabetes increases the risk of Alzheimer's disease and the risk of memory loss in people who don't have Alzheimer's disease. But it hasn't been clear whether people with Alzheimer's disease and diabetes have more rapid memory loss than those who have Alzheimer's disease but no diabetes. http://www.physorg.com/news175884131.html Medicine & Health Tue, 27 Oct 2009 17:45:05 EST news175884131 According a new study of over 3,000 adults aged 70-79, the apparent association between light-to-moderate alcohol consumption and reduced risk of functional decline over time did not hold up after adjustments were made for characteristics related to lifestyle, in particular physical activity, body weight, education, and income. http://www.physorg.com/news174736691.html Medicine & Health Wed, 14 Oct 2009 11:20:02 EST news174736691 (PhysOrg.com) -- A study of mental decline in the years prior to diagnosis of Alzheimer's disease suggests that changing the focus of testing may help physicians detect signs of the disease much earlier. School of Medicine researchers have found that visuospatial skills, evaluated with tasks such as connecting the dots or using a guide to build a structure with blocks, begin to deteriorate up to three years prior to a diagnosis of Alzheimer's. http://www.physorg.com/news174731696.html Medicine & Health Wed, 14 Oct 2009 09:35:40 EST news174731696 A study in the Oct.1 issue of the journal Sleep shows that long-term alcoholism affects sleep even after long periods of abstinence, and the pattern of this effect is similar in both men and women. http://www.physorg.com/news173594832.html Medicine & Health Thu, 01 Oct 2009 06:00:06 EST news173594832 The National Institutes of Health has awarded Rush University Medical Center approximately $5.5 million in grants to study how epigenetic changes - chemical modifications to genes that result from diet, aging, stress, or environmental exposures - define and contribute to memory formation and cognitive decline. Results from the studies could profoundly alter the way the medical community understands, diagnoses, and treats Alzheimer's disease, according to the researchers. http://www.physorg.com/news173552904.html Medicine & Health Thu, 01 Oct 2009 01:20:01 EST news173552904 A new study published in the medical journal Neurology suggests that impaired kidney function is a risk factor for cognitive decline in old age. http://www.physorg.com/news173368269.html Medicine & Health Mon, 28 Sep 2009 15:20:02 EST news173368269 Among individuals with mild cognitive impairment, often considered a transitional state between normal cognitive function and Alzheimer's dementia, those who have more difficulties performing routine activities appear more likely to progress quickly to dementia, according to a report in the September issue of Archives of Neurology. http://www.physorg.com/news172166734.html Medicine & Health Mon, 14 Sep 2009 18:40:01 EST news172166734 (PhysOrg.com) -- Scientists studying cognitive decline that accompanies aging have been interested in nicotinic receptors, part of a key neural pathway that not only enhances learning and memory skills but reinforces addictions as well. The loss of these receptors has been difficult to study in living subjects, but Yale University researchers using advanced imaging technology have successfully tracked the loss of receptors with age, according to a report in the September issue of the journal Neurobiology of Aging. http://www.physorg.com/news171896029.html Medicine & Health Fri, 11 Sep 2009 14:20:01 EST news171896029 Shoppers face a complex and time-consuming task to get the best deal, depending on the store they buy food from and the item involved according to a new booklet "Public behavior in the UK in times of economic decline/rising food prices."

As a result, previous findings may have overestimated atrophy and underestimated normal size for the older brain. http://www.physorg.com/news171605735.html Medicine & Health Tue, 08 Sep 2009 05:30:01 EST news171605735 Watermelon vine decline (WVD) is a new and emerging disease that has created devastating economic losses for watermelon producers in Florida. Caused by the whitefly-transmitted squash vein yellowing virus (SqVYV), the disease created monetary losses estimated at $60 to $70 million in Florida during the 2004 growing season. The virus has become endemic in Florida and has appeared to varying degrees every season since it was first observed. http://www.physorg.com/news171284661.html Biology Fri, 04 Sep 2009 12:05:00 EST news171284661 (AP) -- It's a scene that scientists say is all too common: A commercial fishing boat pulls in a net full of shrimp or tuna and finds a loggerhead sea turtle mixed in with the catch. http://www.physorg.com/news171177115.html Biology Thu, 03 Sep 2009 06:30:02 EST news171177115 (AP) -- The world's only naturally migrating whooping cranes, and the species' best chance for survival, died at about twice their normal rate last year and will likely see an overall drop in their numbers, a worrying sign for the once near-extinct bird that has been making a comeback. http://www.physorg.com/news170443781.html Biology Tue, 25 Aug 2009 18:30:26 EST news170443781 (PhysOrg.com) -- New UCLA research suggests that for seniors age 70 and older, socioeconomic status does not play a major role in the brain's continued ability to function.
