Dementia-associated weight loss begins before the onset of the definite dementia symptoms and accelerates by the time of the diagnosis, according to a study in the January issue of Archives of Neurology, one of the JAMA/Archives journals.
Weight loss in old age is common and may be related to various diseases, according to background information in the article. "It has long been observed that weight loss is common in Alzheimer disease (AD), but this has been documented in people who already have dementia."
Robert Stewart, M.D., From the Institute of Psychiatry, London, and colleagues analyzed data from 1,890 men (aged 77-98 years) who were participants in The Honolulu-Asia Aging Study. This population-based study of Japanese American men included 112 men with incident [new onset] dementia and 1,778 without dementia. The study participants were examined on six occasions over a period of up to 34 years. Weight was measured at each examination and dementia was ascertained at the three most recent examinations.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
