Study: Teen Athletes May Not Report Concussion Symptoms

Despite knowing the risk of serious injury from playing football with a concussion, half of high school football players would continue to play if they had a headache stemming from an injury sustained on the field.

In a new study, physicians from Cincinnati Children's Hospital Medical Center also report that approximately half of athletes wouldn't report concussion symptoms to a coach.

"We aren't yet at the point where we can make specific policy recommendations for sports teams, but this study raises concerns that young athletes may not report symptoms of concussions," says Brit Anderson, MD, an emergency medicine fellow at Cincinnati Children's and the study's lead author. "Other approaches, such as an increased use of sideline screening by coaches or athletic trainers, might be needed to identify injured athletes."

Of athletes surveyed, the vast majority recognized headaches, dizziness, difficulty with memory, difficulty concentrating, and sensitivity to light and sound as concussion symptoms. More than 90 percent recognized the risk of serious injury if they returned to play too quickly.

Despite these high levels of awareness, 53 percent responded that they would "always or sometimes continue to play with a headache sustained from an injury," and only 54 percent indicated they would "always or sometimes report symptoms of a concussion to their coach."

"Further study on concussion education in adolescent athletes and on ways to identify high school athletes who have sustained a concussion would be useful," says Dr. Anderson.

Blood Test for Teen Depression Under Study

Scientists have developed a blood test that one day may help diagnose major depression in teens and young adults.

The test is in very early stages. However, scientists hope it will someday make diagnosing depression more objective for teens.

"The bottom line is that a test is possible from blood that can differentiate teens with major depression from those who do not have it," says scientist Eva Redei, Ph.D., professor of psychiatry and behavioral sciences at Northwestern University Feinberg School of Medicine.

Major depression affects about 1% of children under age 12, Redei says. By late teens and young adulthood, that figure rises to about 25%.

Currently, doctors diagnose depression by asking about symptoms. In developing the blood test, Redei's team focused on blood biomarkers, or indicators, for depression and anxiety. These indicators reflect the activity of genes related to depression. The blood test is very preliminary and not ready for clinical use.

The findings are published in Transitional Psychiatry.

In Teen Music Choices, Anxiety Rules

Bottom line to this study... teens conform (at least in music choices) to their peers not to be popular, but to avoid the emotional anxiety and pain of being a "contrarian."

According to the findings of a study recently published in Neuroimage, when it comes to the music teens buy, a lot of those purchases are made out of fear -- a fear well known to adolescents all over America: terror of social rejection.

The fear of social rejection is so strong in adolescents because their relationships are essential for passing on the lessons that will enable them to join adult society. In order to do this properly and efficiently, teenagers come equipped with the ability to learn fast and furiously from their peers, especially those who wield more social power  -- who are older or more popular. Although this system developed because it helps  the teen transition to adulthood, it has proven an excellent principle upon which to base economic decisions. The popular kids dictate teen culture, and if they endorse it (Twilight, anyone?) it will sell.

The researchers chose to study adolescents between the ages of 12 and 17, a cohort thought to be highly susceptible to social influence, and known to buy at least one third of albums in the United States. Each participant heard a short clip of a song downloaded from the social-networking website Myspace. Following the clip they were asked to make two ratings, one indicating how familiar they were with the clip (which was always the hook or chorus of the chosen song) and one indicating how much they liked the clip on a five point scale. The clip was then played a second time, and they were again asked to rate how much they liked the song. However, in two thirds of these second trials the teens were shown a popularity rating that was estimated based on the number of times the song was downloaded.

When no information about the popularity of a song was displayed, teens changed their likability rating of the song 12 percent of the time. Not surprisingly, after being shown the popularity of a song, teens changed their ratings more frequently, on average 22 percent of the time. This difference was highly significant, and it is worth noting that among those who changed their likability ratings, 79 percent of the time teens changed their ratings in the direction of the popularity rating -- they followed the crowd.

These behavioral findings validate a great deal of previous research on conformity, and demonstrate that it is alive and well in the average American adolescent.

But, did teens actually “follow the crowd” or, upon further reflection and information from their peers, changed their intrinsic preference for a particular piece of music? The researchers investigated the question by looking at brain activity, and found it had nothing to do with increased liking of the music. Further, the research indicated that when teens became aware they held a unpopular likability rating for a song, brain activity registered in an area associated with anxiety and pain.

So, the researchers argue, conforming seems to be motivated not by the positive utility of behaving like your peers, but instead out of anxiety and pain at the prospect of being a “contrarian.”

Teen Brain: Adult Reasoning Capacity, Emotional Maturity Not So Much

If you have or have had teens at home or work with them, there is absolutely no surprise in this new study's finding that their emotional maturity development lags behind their reasoning capacity.

From a physiological standpoint, this study seeks to provide more understanding into the developing teen brain. From a practical standpoint, quite simply teens are "rookie" adults. They need time, guidance, and experiences to help them move toward maturity. It's worthwhile to note that teens are prone to experimentation and making some poor choices along the way.

Parents can mitigate some of the negative consequences by equipping teens with decision making skills including helping them learn to evaluate outcomes of different choices, and by providing loving support, appropriate discipline, along with lots of patience and grace.

A 16-year-old might be quite capable of making an informed decision about whether to end a pregnancy – a decision likely to be made after due consideration and consultation with an adult – but this same adolescent may not possess the maturity to be held to adult levels of responsibility if she commits a violent crime, according to new research into adolescent psychological development.

"Adolescents likely possess the necessary intellectual skills to make informed choices about terminating a pregnancy but may lack the social and emotional maturity to control impulses, resist peer pressure and fully appreciate the riskiness of dangerous decisions," said Laurence Steinberg, PhD, a professor of developmental psychology at Temple University and lead author of the study. "This immaturity mitigates their criminal responsibility."

Steinberg and his co-authors address this seeming contradiction in a study showing that cognitive and emotional abilities mature at different rates.

The findings appear in the October issue of American Psychologist, published by the American Psychological Association.
