Forget that stereotype about the dumb jock. A new study reveals that kids who are more physically fit score higher on geography tests, too. Previous research has found that out-of-shape kids get lower grades in school and perform worse on tasks involving memory and other types of cognitive function. In addition, mice that exercise have better spatial learning and memory than sedentary mice. For the new study, researchers from the University of Illinois at Urbana-Champaign wondered whether there was a correlation between physical fitness and learning.

Jonah Lehrer is the Los Angeles guy who writes about brains, and he has them aplenty too. He wonders how our noggins make us individually distinct, and yet how the basic factory model means that so many of our brains are wired the same. In books such as "Proust Was a Neuroscientist," Lehrer metaphorically pokes at our gray matter, and in his latest, "Imagine, How Creativity Works," considers the neuroscience of the divine spark. For my "Patt Morrison Asks" column , I questioned him about the trope that depression can stimulate creativity, which invariably leads to the hypothetical, "If we'd been able to prescribe antidepressants for the dispirited geniuses of the past, would we be deprived of their music and their art?"

Having childhood attention deficit hyperactivity disorder could lead to a life of obesity, even if ADHD symptoms disappear in adulthood, a new study shows. The study, which followed up on 207 middle-class men who had been diagnosed with ADHD as children, found that some 33 years after their diagnosis, their body mass index was significantly higher than those without ADHD. Their propensity to become obese was twice that of adults who were never diagnosed with ADHD, according to the study published Monday in the journal Pediatrics.

About 3% to 7% of children 5 to 17 years old in the United States have attention-deficit/hyperactivity disorder , or ADHD, according to the Centers for Disease Control and Prevention. The CDC labels it "one of the most common neurobehavioral disorders of childhood. " It also breaks down ADHD into three different categories: predominantly inattentive (which was once called attention deficit disorder, or ADD), predominantly hyperactive-impulsive and combined. The Orlando Sentinel's health blog Vital Signs reports on a recent study that measured the effect of background noise on inattentive students called "A little white noise may help ADD students.

The effects of methylphenidate -- a stimulant used to treat attention-deficit hyperactivity disorder -- are interesting. The drug clearly helps many people with ADHD with mental focus and concentration. And although many parents fear giving the medication to children diagnosed with ADHD because it is a drug (and drugs can be abused), studies show that those children and teens who benefit from the medication are less likely to abuse drugs. Kids with ADHD who are untreated are at higher risk for substance abuse issues.

Go to a busy street in your community and count the next 25 adolescents who walk, bike, skateboard, stroll or saunter past. Odds are that two of those 25 kids (8.3% to be exact) would own up to having experienced 14 or more days in the last month that he or she considered "mentally unhealthy," according to a comprehensive report on the mental health of American youth issued Thursday. Between 2005 and 2010, roughly 2 million American adolescents between 12 and 17 acknowledged that for more than half of the previous month, they routinely had felt sad, angry, disconnected, stressed out, unloved or possibly willing to hurt themselves -- or others.

While Carl Dan Claes' murder was tragic, the logic behind his mother's naming the Tustin Unified School District as defendant in a lawsuit is certainly baffling ("Mother Files Suit Over Claes Murder," May 18). Even if it were true that the victim had informed his teacher that a number of kids "were out to get him," there was very little the school could have done in the absence of any concrete evidence. In addition, the murder did not even take place on the school ground. In the rest of the legally sane world, this type of lawsuit against a presumably innocent party would likely be thrown out of court with a reprimand by a magistrate or judge.

A growing body of evidence is suggesting that exposure to organophosphate pesticides is a prime cause of attention deficit hyperactivity disorder, ADHD. The findings are considered plausible to many experts because the pesticides are designed to attack the nervous systems of insects. It is not surprising, then, that they should also impinge on the nervous systems of humans who are exposed to them. Forty organophosphate pesticides are registered in the United States, with at least 73 million pounds used each year in agricultural and residential settings.

Teri Burley scanned the exhibitors' tables. There was a metronome-like device intended to help children improve their attention spans and coordination. There were dozens of books containing the latest research on a disorder that affects thousands of children like her two sons. "It's like a candy store here," Burley said as she surveyed the Anaheim conference devoted to people suffering from Attention Deficit/Hyperactive Disorder.
