Education does not protect against age-related memory loss, say USC researchers
01-09-2007 · EurekAlert!Adults over 70 with higher levels of education forgot words at a greater rate than those with less education, according to a new study from the University of Southern California. The findings, published in the current issue of Research on Aging, suggest that after age 70, educated adults may begin to lose the ability to use their schooling to compensate for normal, age-related memory loss.

- New gene linked to macular degeneration risk
10-19-2006 · EurekAlert!
Researchers at the John A. Moran Eye Center at the University of Utah have identified a gene called HTRA1 that contributes to a major risk of age related macular degeneration, the most common cause of irreversible vision loss in the developed world. The discovery of this gene allows anyone to take a simple blood test to find out if they are up to 700 percent more likely to develop AMD than the average person.

- Laser treatment not effective in preventing vision loss for people with early AMD
11-01-2006 · EurekAlert!
According to a study that appears in the November 2006 issue of the journal Ophthalmology, researchers at the University of Pennsylvania School of Medicine and 21 other clinical centers have found that low-intensity laser treatment -- thought to be potentially beneficial in slowing or preventing the loss of vision from age-related macular degeneration -- is ineffective in preventing complications of AMD or vision loss.

- Limiting refined carbohydrates may stall AMD progression
10-08-2007 · EurekAlert!
Eating fewer refined carbohydrates may slow the progression of age-related macular degeneration and ease the growing public health burden due to vision loss, report Tufts researchers. People who consumed the most refined carbohydrates were 17 percent more likely to develop blinding AMD than those who consumed the least.

- Yerkes researchers pave the way for earlier diagnosis and treatment of retinal degenerative diseases
11-06-2006 · EurekAlert!
Researchers at the Yerkes National Primate Research Center, Emory University and the Atlanta VA Hospital have used magnetic resonance imaging to produce images of the eyeХs retinal layers. The research has the potential to revolutionize the way retinal degenerative diseases, such as retinitis pigmentosa, glaucoma, age-related macular degeneration and diabetic retinopathy, are diagnosed and treated. Accelerating detection and treatment of such diseases ultimately could help prevent vision loss.

- Einstein researchers use novel approach to uncover genetic components of aging
08-24-2007 · EurekAlert!
People who live to 100 or more are known to have just as many -- and sometimes even more -- harmful gene variants compared with younger people. Now, scientists at the Albert Einstein College of Medicine of Yeshiva University have discovered the secret behind this paradox: favorable "longevity" genes that protect very old people from the bad genes' harmful effects. The novel method used by the researchers could lead to new drugs to protect against age-related diseases.

- Loss of gene leads to protein splicing and buildup of toxic proteins in neurons
09-27-2007 · EurekAlert!
Researchers at Mayo Clinic in Jacksonville have discovered how loss of a gene can lead to accumulation of toxic proteins in the brain, resulting in a common dementia, and they say this mechanism may be important in a number of age-related neurological disorders.

- Link between carbohydrate quality and vision loss is strengthened by new data
07-11-2007 · EurekAlert!
People consuming diets with a higher glycemic index than average were at greater risk of developing advanced age-related macular degeneration, report researchers at Tufts. The researchers suggest that twenty percent of cases of advanced Age-Related Macular Degeneration might have been prevented if individuals had consumed a diet with a glycemic index below average.

- Women on hormone therapy regain emotion response
10-16-2006 · EurekAlert!
Older women on hormone therapy are more sensitive to negative events, confirming speculation that age-related estrogen loss affects the brain's ability to process emotion, an Oregon Health & Science University study shows. Researchers found that hormone therapy appears to reverse the age-related loss of arousal to negative emotional events experienced by the elderly. It also points to specific changes in the brain's arousal system, in the regions that process emotion, and intensification of negative emotions.

- Immune cell age plays role in retinal damage in age-related macular degeneration
11-01-2007 · EurekAlert!
Studying a mouse model of age-related macular degeneration, the leading cause of blindness in older Americans, scientists at Washington University School of Medicine in St. Louis have found age is key in determining whether damaging blood vessels will form beneath the retina and contribute to vision loss.

- Using fMRI to study brain development
11-30-2007 · EurekAlert!
Using fMRI to study early brain development requires learning more about the fMRI signal in the developing brain. MIT neuroscientists studying rats found the signal changes during first few weeks of life in relation to actual brain activity. Correcting for those changes, the researchers could monitor the development of the rat brain. The findings also identified a key player in the age-related changes in neurovascular coupling that gives rise to the BOLD signal.
