Forgetful? You may be losing more than just your memory

12.09.2006
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: UNH scientists help provide first-ever views of elusive energy explosion

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...

Im Focus: A Chip with Blood Vessels

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...

Im Focus: A Leap Into Quantum Technology

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...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

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...
