Multiple therapies curb declining ability to learn with age

18.01.2005


Combination of behavioral enrichment and antioxidant supplementation in diet reveal clear-cut benefits



A new study of beagles led by researchers at the University of Toronto at Scarborough underscores the importance of using a combination of diet and behaviour therapies to curb the progressive decline in the ability to learn that occurs with advanced aging. “We were really surprised just how clear-cut the benefit is of using a combined therapy,” says lead investigator and psychology professor Bill Milgram of the U of T at Scarborough, who specializes in aging research.

The results of the study, published in the January 2005 issue of Neurobiology of Aging, looked at the impact four combinations of behavioural enrichment and supplementation of diet with antioxidants had on a beagle’s ability to learn as the senior dog grew older. The first group had a regular diet and regular experience; the second received a regular diet and enriched experience; the third group a regular experience and an enriched diet; and the fourth group an enriched diet and an enriched experience.


Whereas previous studies have looked at dogs of different ages all at once to identify age-related differences, this investigation followed four groups of dogs over a period of two years. As predicted, the researchers found a dog’s ability to learn declines with age. What they had not anticipated was seeing such a statistically-significant benefit of combining behavioral enrichment and the antioxidant supplementation compared to giving either alone.

“Since humans and dogs have many biological and behavioral parallels, I predict similar results would be attained in people,” notes Milgram. The study was funded by the National Institute of Aging and the U.S. Department of the Army. The following conflict of interest was declared by the authors with respect to publication of this paper: investigator Steven Zicker is an employee of Hill’s Pet Nutrition Inc., which has commercialized the antioxidant fortified food used in the study.

Im Focus: Why we need erasable MRI scans

New technology could allow an MRI contrast agent to 'blink off,' helping doctors diagnose disease

Magnetic resonance imaging, or MRI, is a widely used medical tool for taking pictures of the insides of our body. One way to make MRI scans easier to read is...

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
