The Relationship Between Gender and Postconcussion Symptoms After Sport-Related Mild Traumatic Brain Injury
TL;DR: The authors sought to define the relationship between gender and postconcussion symptoms (PCSx) at 3 months after sport‐related mild traumatic brain injury (mTBI) and to examine whether age, source of PCSx reporting, previous head injury or loss of consciousness, or the sport type in which the mTBI was incurred explain any observed gender differences.

The Efficacy of Soccer Headgear.
TL;DR: The Protector headband appeared the most effective at reducing time to peak force and impulse within the design of this study, and the clinical effectiveness of these products remains to be seen.
Magnetic resonance imaging and computerized tomography in relation to the neurobehavioral sequelae of mild and moderate head injuries
Harvey S. Levin,Eugenio G. Amparo,Howard M. Eisenberg,David H. Williams,Walter M. High,Craig B. McArdle,Richard L. Weiner +6 more
TL;DR: Twenty patients admitted for minor or moderate closed-head injury were studied to investigate the relationship between magnetic resonance imaging (MRI) and neurobehavioral sequelae and found deficits in frontal lobe functioning and memory were related to the size and localization of the lesions as defined by MRI.
Repeat Traumatic Brain Injury in the Juvenile Rat Is Associated with Increased Axonal Injury and Cognitive Impairments
TL;DR: It is demonstrated that an experimental closed head injury in the rodent with low mortality rates and absence of gross pathology can produce measurable cognitive deficits in a juvenile age group, and the introduction of a second injury 24 h after the first impact resulted in increased axonal injury, astrocytic reactivity and increased memory impairment.
Early symptom burden predicts recovery after sport-related concussion
TL;DR: The only independent predictor of prolonged symptoms after sport-related concussion is overall symptom burden, and recursive partitioning analysis was used to develop a multivariate prediction model for identifying athletes at risk for a prolonged recovery from concussion.

Prognosis of severe brain injury
Olli Heiskanen,P. Sipponen +1 more
TL;DR: It is concluded that in patients over 60 no special or heroic methods of treatment are indicated but that in children and adolescents every effort should be made as long as there has not been respiratory arrest and cerebral death.
