Get Moving: Daily Exercise May Reduce Alzheimer’s Disease Risk at Any Age

Daily physical exercise may reduce the risk of Alzheimer’s disease, even in people over the age of 80, according to a study published in the April 18, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology.

“The study showed that not only exercise but also activities such as cooking, washing the dishes and cleaning are associated with a reduced risk of Alzheimer’s disease,” said study author Aron S. Buchman, MD, with Rush University Medical Center in Chicago and a member of the American Academy of Neurology. “These results provide support for efforts to encourage physical activity in even very old people who might not be able to participate in formal exercise but can still benefit from a more active lifestyle.”

For the study, a group of 716 people with an average age of 82 wore an actigraph, a device that monitors activity, on their non-dominant wrist continuously for 10 days. All exercise and non-exercise was recorded. They also were given annual tests during the four-year study that measured memory and thinking abilities. During the study, 71 people developed Alzheimer’s disease.

Participants also self-reported their physical and social activity. Buchman said this is the first study to use an objective measurement of physical activity in addition to self-reporting. “This is important because people may not be able to remember the details correctly,” he said.

The research found that people in the bottom 10 percent of daily physical activity were more than twice as likely to develop Alzheimer’s disease as people in the top 10 percent of daily activity.

The study also showed that those people in the bottom 10 percent of intensity of physical activity were almost three times as likely to develop Alzheimer’s disease as people in the top 10 percent of intensity of physical activity.

“Since the actigraph was attached to the wrist, activities like cooking, washing the dishes, playing cards and even moving a wheelchair with a person’s arms were associated with a lower Alzheimer’s risk,” said Michal Schnaider-Beeri, PhD, of Mount Sinai School of Medicine in New York in an accompanying editorial. “These are low-cost, easily accessible and side-effect free activities people can do at any age, including very old age, to possibly prevent Alzheimer’s disease.”

The study was supported by the National Institute on Aging, the Illinois Department of Public Health and the Robert C. Borwell Endowment Fund.

The American Academy of Neurology, an association of more than 25,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
