At the time of the first MRI scans, the turquoise color shows areas of the hippocampus in patients with mild Alzheimer’s disease that are shaped differently than in healthy older people. Two years later, even more changes have occurred, represented by the purple color.Even when people have no symptoms, their brains already may be dotted with the plaques and tangles that characterize Alzheimer’s disease. As treatments to halt the progress of Alzheimer’s disease appear on the horizon, scientists are looking for new ways to identify Alzheimer’s-associated changes in the brain before cognitive decline begins. By examining brain images, researchers, led by John G. Csernansky, M.D., the Gregory B. Couch Professor of Psychiatry, and Lei Wang, Ph.D., research associate in psychiatry, both at Washington University’s Silvio Conte Center for Neuroscience Research, found that the volume and shape of certain brain structures change in different patterns during Alzheimer’s disease than in healthy aging. They believe that someday using these imaging techniques may allow for earlier diagnosis of Alzheimer’s disease, preferably before the most devastating symptoms appear.

That is the implication of a detailed study of the neuronal activity in a critical area of the brain, called the anterior cingulate cortex (ACC), published in the Oct. 3 issue of the journal Science. The finding is important because the ACC plays a key role in disorders such as schizophrenia and obsessive-compulsive disorder in humans, suggests Joshua Brown, study co-author and WUSTL research associate in psychology.

U.S. Administration on AgingAging is a women’s issue because women provide the bulk of care and support to older adults.An aging parent wants to keep the car keys, while his adult daughter thinks he is a hazard to himself and others on the road. Or a widow who has lived in her home for 55 years refuses to move out, although her children worry that she’s too frail to manage the stairs. As more and more adult children face caring for their aging parents in the coming decades, an expert on the clinical psychology of aging says the key to dealing with these types of situations is to discuss them before they become a reality. “Don’t procrastinate,” says Brian D. Carpenter, Ph.D., an assistant professor of psychology in Arts & Sciences at Washington University in St. Louis. “Start the process of talking to your aging parents early — before a crisis.”

Nutritionist offers tips on controlling Halloween candy consumption.Halloween is just around the corner, and most kids can’t wait. When else can you dress up in funny — or frightening — costumes, go door to door, and collect all the free candy you can fit in your bag? And with many kids opting to carry pillowcases instead of cutely decorated trick or treat sacks, that’s a lot of candy! While Halloween is a kid’s dream, it can be a nightmare for parents who struggle all year to get their children to eat enough fruits and vegetables and avoid excessive sugars and saturated fat. So how can parents keep their kids from gobbling down all that they bring home from a night of trick or treating — and from eating it all in one sitting? A registered dietician at Washington University in St. Louis offers some helpful tips.

Mary Butkus/WUSTL PhotoFoster care teens have a desire to attend college, study shows.A solid education is considered the foundation for a productive future, but for teens in foster care, education beyond high school is rarely a reality. In fact, a Westat study found that only 44 percent of 18-year-olds leaving the independent living program of the foster care system completed high school. But despite common thought, this dismal percentage is not due to a lack of educational aspirations among teens in foster care. According to a recent study at the George Warren Brown (GWB) School of Social Work at Washington University in St. Louis, a surprisingly high percentage — 70 percent — of teens in the foster care system have a desire to attend college.

Yet, globalization has produced opportunity and improvements in social welfare for those nations able to take advantage of its benefits. Nations who fail to take full advantage of globalization may have only themselves to blame, according to a study in a forthcoming issue of the Journal of International Management.

The recent decisions by Oklahoma and Colorado federal courts invalidating the Federal Trade Commission’s “Do Not Call List” were major victories for telemarketing companies, “but a tragedy for the rest of us,” says Neil M. Richards, associate professor of law at Washington University in St. Louis. “Even with the quick reversal of the Oklahoma decision by Congress and President Bush, the Colorado decision remains a major roadblock for the List,” notes Richards. “The FTC and the Federal Communications Commission have been warned by Judge Harrington in Colorado not to go against his order, and Congress has no power to overrule the judge’s decision- they cannot change the meaning of the First Amendment as interpreted by the Courts.”
