NPR (12/21, Hamilton) reports that a study published in Neurology suggests that “sleep quality and brain function improved in tandem” for patients “hospitalized for moderate to severe traumatic brain injuries.” According to NPR, “the results raise the possibility that patients with brain injuries might recover more quickly if hospitals took steps to restore normal sleep patterns.”

The Boston Globe (12/21, Freyer) reports the “brain abnormalities that cause dyslexia may be deeper and more pervasive than previously thought,” according to a new study published in the journal Neuron. Researchers found that “neural adaptation was reduced” in people with dyslexia “even in tasks unrelated to reading, suggesting that dyslexia affects many brain regions, not just those involved with language.”

HealthDay (12/21, Norton) reports the researchers used brain imaging technology and found that adults and children with dyslexia demonstrated “less ability to ‘adapt’ to sensory information,” not just written words, compared to people without dyslexia.

Medical Daily (12/21, Drain) reports research suggests that “around two-thirds of women with anorexia nervosa or bulimia will eventually recover.” Investigators arrived at this conclusion after analyzing data on “246 participants for more than 20 years.” The findingswere published online Dec. 20 in the Journal of Clinical Psychiatry.

Psychiatric News (12/21) reports that even though “‘for most patients with anorexia nervosa and bulimia nervosa, recovery is durable, we found that 10.5% of those with anorexia nervosa and 20.5% of those with bulimia nervosa who achieved recovery in the first decade had relapsed at long-term follow-up,’ the authors wrote.”

The AP (12/20, Tanner) reports that a study published in JAMA indicates that physical activity may help children recover from concussions. Researchers “surveyed about 2,400 kids aged 5 to 18 treated for concussions in nine emergency departments in Canada.” They found that “a month after their concussions, ongoing or worse symptoms were more common in children and teens who were inactive during the week following injury, compared with those who engaged in physical activity during that first week.” Their findings “were similar even among those who early on had three or more concussion symptoms.”

HealthDay (12/20, Preidt) reports researchers at Ohio State University found that “student were far more likely to engage in a violent act if a friend has also done so.” Researchers collected data in “the mid-1990s from more than 5,900 seventh- through 12th-graders at 142 U.S. schools” and found that “youths were 48 percent more likely to be in a serious fight and 140 percent more likely to pull a weapon on someone if a friend had done the same.” Youths were also “up to 183 percent more likely to injure someone badly, the researchers said.” The findings were published online Dec. 20 in the American Journal of Public Health.
