Insights into Parkinson's balance problems

In PD, disorganized sensorimotor signals cause muscles in the limbs to contract, such that both a muscle promoting a motion and its antagonist muscle are Read more

Cajoling brain cells to dance

“Flicker” treatment is a striking non-pharmaceutical approach aimed at slowing or reversing Alzheimer’s disease. It represents a reversal of EEG: not only recording brain waves, but reaching into the brain and cajoling cells to dance. One neuroscientist commentator called the process "almost too fantastic to believe." With flashing lights and buzzing sounds, researchers think they can get immune cells in the brain to gobble up more amyloid plaques, the characteristic clumps of protein seen in Read more

Stress increases health risks to mother and fetus

At Emory’s fifth annual predictive health symposium “Human Health: Molecules to Mankind,” Emory GYN/OB Sarah L. Berga, MD, discussed the state of childbirth in the United States and how maternal stress affects pregnant women and their fetuses.

Berga is McCord professor and chair of the Department of Gynecology and Obstetrics at Emory School of Medicine. Sadly, Berga has seen maternal mortality rise steadily since the 1980s when she entered her medical residency. Georgia, she says, has the worse maternal mortality in the country. And the United States fares worse than many countries when it comes to maternal mortality.

Despite the unfortunate rise in maternal mortality of late, the good news is physicians have now started to pay more attention to the effect of stress—both the physical and emotional kind—on women and their fetuses. Recent research shows stress has the same negative effect on the body as do organic diseases, such as thyroid disease. In fact, too much stress reduces thyroxine levels by about 50 percent, says Berga. But because there’s no clinical recognition of this, tests are needed to determine if thyroxine levels are indeed insufficient.
