ACSM 2009: Multiple Concussions Linked to Postheading Deficits in Soccer Players “Athletes with a history of multiple concussions are significantly more likely to suffer from impaired balance after repeated purposeful heading of a soccer ball, according to a study presented here at the annual meeting of the American College of Sports Medicine. The findings underscore the need for clinicians to exercise caution before authorizing athletes to return to soccer after a concussion, despite a number of previous studies suggesting that purposeful heading is not a risk factor in athletes who have not had previous head injuries.”
After Concussion, Follow-Up Visit a Must “Children admitted to a hospital with a concussion should have a follow-up assessment with a clinician before resuming normal play activities or sports, a new study suggests.”
Concussion Experts: For Kids -- No Sports, No Schoolwork, No Text Messages “For children and adolescents, the guidance strongly reiterates several key points for coaches, parents, and physicians: • Injury to the developing brain, especially repeat concussions, may increase the risk of long term effects in children, so no return-to-play until completely symptom free. • No child or adolescent athlete should ever return to play on the same day of an injury—regardless of level of athletic performance. • Children and adolescents may need a longer period of full rest and then gradual return to normal activities than adults. For children, "cognitive rest" is a key to recovery. While restrictions on physical activity restrictions are also important, cognitive rest must be carefully adhered to, including limits on cognitive stressors such as academic activities and at-home/social activities including text messaging, video games, and television watching.”
Concussion In Former Athletes Can Affect Mental And Physical Processes Later In Life “Researchers have found the first evidence that athletes who were concussed during their earlier sporting life show a decline in their mental and physical processes more than 30 years later.”
New Study Shows Long-term Dangers Of Severe Concussions “Parents of kids suffering from severe or multiple concussions need to pay attention and track their child's symptoms across time. Post-concussive symptoms, according to Dr. Yeates, can be divided into three groups: somatic, cognitive, and emotional. Somatic symptoms like headaches and fatigue generally resolve themselves quickly. However, cognitive symptoms like trouble paying attention and forgetfulness may persist longer. "Parents should pay particular attention to these symptoms when they last more than a month or two and report all ongoing symptoms to their child's doctor so they can intervene appropriately," said Dr. Yeates. To better understand which kids may be at risk Doctor Yeates, of Nationwide Children's Hospital followed nearly 200 children with concussions for a year. His study, published in Pediatrics, found that while most kids had few problems, one out of every four experiences significant post concussive symptoms, some of which never fully resolved. And those whose concussions resulted in a loss of consciousness, amnesia or an abnormal CT scan were more likely to have symptoms that persist.”

Brain function decline in healthy retired athletes who sustained their last sports concussion in early adulthood (Brain 2009) “Relative to controls, former athletes with a history of concussion had: (i) lower performance on neuropsychological tests of episodic memory and response inhibition; (ii) significantly delayed and attenuated P3a/P3b components; (iii) significantly prolonged CSP and (iv) significantly reduced movement velocity (bradykinesia). The finding that the P3, the CSP as well as neuropsychological and motor indices were altered more than three decades post-concussion provides evidence for the chronicity of cognitive and motor system changes consecutive to sports concussion.”
