Returning to Sports After Concussions

Be careful not to rely on what adolescent athletes tell you about their recovery from concussions as the sole criterion for making return-to-play decisions, researchers from UPMC and the University of Pittsburgh warn sports medicine practitioners.

 

In findings published online in the inaugural issue of Applied Neuropsychology: Child, researchers found that young athletes neglect the more subtle symptoms — neuropsychiatric and sleep issues — and base their perceptions of their recovery primarily on physical (somatic) symptoms such as headache and nausea.

Results indicate that when athletes gauge their own readiness to return-to-play, their physical symptoms account for 56 percent of their self-assessment, whereas their performance on objective neurocognitive testing only accounts for 28 percent. While the statistical analyses revealed that they judged their recovery on somatic and cognitive symptoms almost twice as strongly as neurocognitive testing, the sleep and neuropsychiatric symptoms ranked ahead of their performance on the objective test data by only a few percentage points.

“Our findings suggest that young athletes may not perceive their cognitive deficits as well as they perceive their somatic symptoms,” said Anthony Kontos, Ph.D., assistant research director with the UPMC Center for Sports Medicine Concussion Program. “Therefore, it is important to assess their cognitive deficits using neurocognitive concussion tests and a comprehensive clinical evaluation.” [continue reading…]

Stressed Men Are More Social

Freiburg researchers refute the common belief that stress always causes aggressive behavior

 
A team of researchers led by the psychologists and neuroscientists Prof. Markus Heinrichs and Dr. Bernadette von Dawans at the University of Freiburg, Germany, examined in a study how men react in stressful situations – and have refuted a nearly 100-year-old doctrine with their results. According to this doctrine, humans and most animal species show the “fight-or-flight” response to stress. Only since the late 1990s have some scientists begun to argue that women show an alternate “tend-and-befriend” response to stress – in other words, a protective (“tend”) and friendship-offering (“befriend”) reaction. Men, in contrast, were still assumed to become aggressive under stress. Von Dawans refuted this assumption, saying: “Apparently men also show social approach behavior as a direct consequence of stress.”

With this study, the research team experimentally investigated male social behavior under stress for the first time. The results are published in the prestigious international journal Psychological Science. The economists Prof. Ernst Fehr of the University of Zurich, Switzerland, and Prof. Urs Fischbacher of the University of Konstanz, Germany, as well as the psychologist Prof. Clemens Kirschbaum from the Technical University of Dresden, Germany, also participated in the study. Last year, Heinrichs and von Dawans already developed a standardized procedure for inducing stress in groups using a public speaking task. The researchers examined the implications of this stressor for social behavior using specially designed social interaction games.. These games allowed them to measure positive social behavior – for example, trust or sharing – and negative social behavior – for example, punishment.

In the study, subjects who were under stress showed significantly more positive social behavior than control subjects who were not in a stressful situation. Negative social behavior, on the other hand, was not affected by stress. For Markus Heinrichs, this has far-reaching consequences for our understanding of the social significance of stress: “From previous studies in our laboratory, we already knew that positive social contact with a trusted individual before a stressful situation reduces the stress response. Apparently, this coping strategy is anchored so strongly that people can also change their stress responses during or immediately after the stress through positive social behavior.”

couple distantHow good are married couples at recognizing each other’s emotions during conflicts? In general, pretty good, according to a study by a Baylor University researcher. But if your partner is angry, that might tell more about the overall climate of your marriage than about what your partner is feeling at the moment of the dispute.

What’s more, “if your partner is angry, you are likely to miss the fact that your partner might also be feeling sad,” said Keith Sanford, Ph.D., an associate professor of psychology and neuroscience in Baylor University’s College of Arts & Sciences. His study — “The Communication of Emotion During Conflict in Married Couples” —is published online in the American Psychological Association’s Journal of Family Psychology.

“I found that people were most likely to express anger, not in the moments where they felt most angry, but rather in the situations where both partners had been feeling angry over a period of time,” he said. “This means that if a couple falls into a climate of anger, they tend to continue expressing anger regardless of how they actually feel . . . It becomes a kind of a trap they cannot escape.”

Common spats that might fester deal with in-laws, chores, money, affection and time spent on the computer.

Sanford found that when people express anger, they often also feel sad. But while a partner will easily and immediately recognize expressions of anger, the spouse often will fail to notice the sadness.
“When it comes to perceiving emotion in a partner, anger trumps sadness,” he said. [continue reading…]
