Further, many studies of concussion have used self-reported concussion signs and symptoms to classify groups of athletes (eg, by number of previous concussions, presence of LOC or PTA). However, the accuracy of self-reported concussion history has been questioned. This study examined the recall of concussion signs and symptoms among recently injured athletes (ie, within the past 7 days) and healthy athletes who had not been concussed for at least 1 month.

We explored patterns of recovery for neurocognition and postconcussive symptoms following concussion in children and adolescents. Using a prospective, longitudinal design, we collected baseline data on 728 children and adolescents aged 10-17 years. 10 participants sustained a concussive injury (n=10) in the 12 months following baseline testing and they were reviewed at day 5, 10 and 30 postconcussion. Assessments included the CogSport for Kids computerised test battery to evaluate neurocognitive function and self-report, and parent measures of postconcussive symptoms. At day 30, parents also completed measures rating their child's quality of life and executive functions. Children and adolescents displayed a gradual reduction in postconcussive symptoms over the 30 days following injury. At day 5, 87% of participants were reporting physical and cognitive symptoms, with a generalised reduction in ...

Some of the pathological findings reported in the literature may be encountered with age and other neurodegenerative diseases. However, the focality of the p-tau cortical findings in particular, and the regional distribution, are believed to be unique to CTE. The described clinical features in recent cases are very similar to how depression manifests in middle-aged men and with frontotemporal dementia as the diseas...

A decrease in the proportion of head injury among emergency department (ED) presentations for hurling-related injury has coincided with voluntary use of helmet and face protection since 2003. A similar decrease in proportions has not occurred in hand injury. We aim to quantify hurling-related ED presentations and examine variables associated with injury. In particular, we were interested in comparing the occurrence of hand injury in those using head and face protection versus those who did not. This study utilised a retrospective cross-sectional study design. This study took place at a university hospital ED over a 3-month period. A follow-up telephone interview was performed with 163 players aged ≥16 years to reflect voluntary versus obligatory helmet use. The hand was most often injured (n=85, 52.1%). Hand injury most commonly occurred from a blow of a hurley (n=104, 65%), and frac...
