WEDNESDAY, June 11 (HealthDay News) -- People with sleep apnea show tissue loss in brain regions that help store memory, a University of California, Los Angeles (UCLA) study shows. "Our findings demonstrate that impaired breathing during sleep can lead to serious brain injury that disrupts memory and thinking," principal investigator Ronald Harper, a professor of neurobiology at the David Geffen School of Medicine at UCLA, said in a prepared statement. People with sleep apnea stop breathing and awaken repeatedly during the night, leading...

TUESDAY, June 24 (HealthDay News) -- The Alzheimer's drug memantine (brand name Namenda) may help reduce a form of brain injury that affects many premature babies, according to a Children's Hospital Boston study. Hypoxic-ischemia, a compromise of the brain's blood and oxygen supply, can lead to cerebral palsy and cognitive/behavioral problems. In experiments with rats that had brain injury similar to that seen in some premature infants, the Children's Hospital team found memantine could reduce damage to cells called...

MONDAY, May 12 (HealthDay News) -- A new way of analyzing MRI data can detect a subtle but serious kind of brain injury and help determine how a patient may recover, say researchers at the University of Texas Southwestern Medical Center at Dallas. This kind of injury, called diffuse axonal injury (DAI), occurs when the head suddenly stops moving, such as during a motor vehicle crash, and axons are damaged or deformed. Axons are long, thin extensions that reach from one area to another.

Welterweight boxer Oscar Diaz remains in critical but stable condition two days after collapsing during a fight, but the doctor who performed surgery on him said he should survive. David Jimenez said Diaz is still in a coma, but that is to be expected after a severe brain injury. "Overall, I think ultimately he should survive the injury and should recover," Jimenez said. But Jimenez said it's too early to tell whether the 25-year-old Diaz, who collapsed before the 11th round of the televised USBA welterweight...

MONDAY, June 23 (HealthDay News) -- In 2005, traumatic brain injuries (TBIs) due to falls resulted in nearly 8,000 deaths and 56,000 hospitalizations among Americans age 65 and older, according to a U.S. Centers for Disease Control and Prevention study. TBIs accounted for 50 percent of all unintentional fall deaths and 8 percent of nonfatal fall-related hospitalizations among older adults. As people age, their risk of falling increases due to a number of factors such as mobility problems due to muscle weakness or poor balance, loss of...

More than 5 million Americans have suffered a traumatic brain injury. A new Web site, brainline.org, offers these people and their families a user-friendly source of information. The site was created by public television and radio station WETA, with funding from the government's Defense and Veterans Brain Injury Center. Brainline offers such online tools as webcasting, videos, a Facebook page, font enlargement, a glossary that can pop up inside text and a one-click option that translates all text into Spanish.
