The Washington Post (9/4, Cha) reports that the Centers for Disease Control and Prevention “takes an in-depth look at how children with” attention-deficit/hyperactivity disorder (AD/HD) “came to get the label through a survey of 2,976 families.”

The CBS News (9/4, Welch) website reports that the new study from the CDC’s National Centers for Health Statistics “estimates that one-third of children in the US with AD/HD were diagnosed before the age of six.” Investigators “learned that the average age at which a child was first diagnosed was seven, but many” youngsters were diagnosed earlier.

The ABC News website reports that “in the vast majority of AD/HD diagnoses, family members are the first to identify signs of the disorder.”

The New York Times (9/2, Reynolds) “Well” blog summarized several studies indicating that exercise may be beneficial for “aging brains.” For example, a 100-participant study published Aug. 5 in PLoS One revealed that “the most physically active elderly volunteers…had better oxygenation and healthier patterns of brain activity than the more sedentary volunteers — especially in parts of the brain, including the hippocampus, that are known to be involved in improved memory and cognition.” A much larger study, published Aug. 25 in the Journal of the American Medical Association, indicated “some small improvements among the oldest exercising volunteers in their working memory and attention.”

CNN (9/2, Ansari) reports that results from an online survey “on mental health, anxiety and suicide indicate that 90% of Americans value mental and physical health equally,” indicating that the “stigma” surrounding mental health issues “appears to be shifting, at least in the” US.

US News & World Report (9/1, Esposito) reports that the survey, which was answered by “2,020 nationally representative adults,” also reveals that even though “47 percent of participants believe they have had a mental health condition, only 38 percent have received treatment” for it, with younger people being more likely than older ones to get help. The survey, which was conducted last month “by Harris and sponsored by the Anxiety and Depression Association of America, the American Foundation for Suicide Prevention and the National Action Alliance for Suicide Prevention,” also found that “about 55 percent of participants have been affected by suicide in some way, according to a joint press release from the three mental health groups.”

The Washington Post (9/1, Dennis) details a new report released by the American Academy of Pediatrics that recommends warning children by the age of nine about the dangers associated with drinking alcohol. The report states, “Surveys indicate that children start to think positively about alcohol between ages 9 and 13 years… Therefore, it is very important to start talking to children about the dangers of drinking as early as 9 years of age.”

The New York Times (9/1, Dell’Antonia) writes the report states that “21 percent of youth acknowledge having had more than a sip of alcohol before 13 years of age, and most (79 percent) have done so by 12th grade.”

NBC News (9/1, Fox) quotes the report as saying, “Among youth who drink, the proportion who drink heavily is higher than among adult drinkers, rising from approximately 50 percent in those 12 to 14 years of age to 72 percent among those 18 to 20 years of age.” This heavy drinking, or binging, was defined as five or more drinks in one sitting. The report also notes that “80 percent of teenagers say their parents are the biggest influence on their decision whether to drink.”
