Forgetful? You may be losing more than just your memory

Older adults who complain their "mind is going" may be losing a part of their brain along with their memory, according to a study published in the September 12, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology.

The study, which looked at 120 people over the age of 60, found people who complained of significant memory problems but still had normal performance on memory tests had reduced gray matter density in their brains even though they weren't diagnosed with Alzheimer's disease or mild cognitive impairment (MCI), which is a transition stage between normal aging and the more serious problems caused by Alzheimer's disease.

When compared to healthy individuals, the study found people who complained of significant memory problems had a three-percent reduction in gray matter density in an area known to be important for memory; there was a four-percent reduction among individuals diagnosed with MCI.

"Significant memory loss complaints may indicate a very early "pre-MCI" stage of dementia for some people. This is important since early detection will be critical as new disease modifying medications are developed in an effort to slow and ultimately prevent Alzheimer's disease," said study author Andrew Saykin, PsyD, Professor of Psychiatry and Radiology at Dartmouth Medical School in Lebanon, New Hampshire, and an affiliate member of the American Academy of Neurology.

While normal aging, MCI and Alzheimer's disease have been associated with the loss of gray matter in the brain, this is believed to be the first study to quantitatively examine the severity of cognitive complaints in older adults and directly assess the relationship to gray matter loss.

Saykin says the findings highlight the importance of cognitive complaints in older adults, and suggest that those who complain of significant memory problems should be evaluated and closely monitored over time. Memory complaints, a cardinal feature of MCI which confers high risk for Alzheimer's disease, are reported in 25 to 50-percent of the older adult population.

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...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
