In the study, 60 young and high-level football players had a telemetry-free telemetry without traumatic or developmental history, measuring the size, location, and direction of their impact on the head. The researchers did not investigate unless they had any effect, the only effect that occurred.
The children were classified into two categories: small player heads (24) and low head impact players (36).
Before reproducing, each child had a functional break function, known as fMRI; At the end of the season of soccer players were repeated. The researchers affect the visual pruritus of the brain's "pruning" process in adolescence.
"Pruning is a key part of brain development," said Muruges, in order to compare and maintain healthy growth of trees to cut dead or unnecessary branches.
"The fractures of ordinary injections are associated with weak connections between different parts of the brain," he said.
After comparing the player's impact level with the results of functional MRI, the researchers found that the most influential groups of young people underwent their pruritus during a period of time.
"Our research has found a sharp decline in gray matter in the front line of the defective way, because they participate in more cognitive functions, such as planning and controlling social behavior," Murugesan said.
"Although teens were critical of brain development, brain remodeling or synaptic pruning, it was a short-term study and continued for many years without players," said Dr. Julian Bailes, a neurosurgery director and NorthShore University HealthSystem Director of Neurological Institute, who did not participate in the research.
"I would call this pilot research," said Isaacson. "Call for action requires more robust research, before and after brain imaging. Studies should also measure cognitive and neurological functions and look for changes."
When we learn more about this topic, Isaacson said that parents should do everything they can to limit sports contact "especially in gaming practice, especially studies that show most of the contact."
Bailes said that he should be careful in all sports, not just football.
"It's football, it's ice hockey, it's a fight," he said. "Crisis and head are any potential sports impact."
