Weight loss may be an early sign of dementia in the elderly

11.01.2005


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.



"Incident dementia was associated with significant previous weight loss, which was independent of a large number of potential confounding factors," the researchers found. "A high proportion of men with dementia at examination 6 had lost at least 5 kg [about 11 pounds], which approaches 10 percent of average body weight for this cohort. This weight loss occurred in many cases over the two to four years prior to reaching the clinical threshold of dementia. The association was similar in AD and vascular dementia."

In conclusion the authors write: "An important consideration arising from research in this area is the extent to which weight loss may be prevented or minimized in dementia. Poor nutrition and frailty frequently complicate later stages of dementia, causing falls, poor wound healing, and increased physical dependence. … The results presented here suggest that weight change and nutritional state in people with dementia should be taken seriously at least from the time of diagnosis if not at earlier stages of more mild cognitive impairment."

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
