Cumulative effect of concussion

TL;DR: To the Editor: The authors would like to comment on the review article by Shuttleworth-Edwards et al.

TL;DR: It is argued that preoccupation with symptomatology and emotional distress are not unique to mild brain trauma but also occur after severe head injury and back injury and relate more to personal interpretation than to objective indicators of injury severity or the injury to the brain itself.

TL;DR: La adecuada valoración and tratamiento de la concusión en el deporte es crucial porque las repetidas concusiones pueden provocar una disminución of the función neurocognitiva, un aumento of los síntomas and, in ocasiones, unos resultados catastróficos.

TL;DR: A prospective epidemiological study followed a national sample of high school and college players for two seasons and found that concussion is the second (high school) or third (college) most frequent injury, is 9 to 10 times more likely to occur in games than in practices, and more than half are the results of helmet-to-helmet contact.

TL;DR: Siegel et al. as mentioned in this paper introduced nonparametric statistics for the behavioral sciences and proposed a statistical test theory for behavioral sciences, which is based on the non-parametric test theory.

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.
