TL;DR: This article reviews, analyses and provides commentary on the most recent literature concerning recurrent traumatic brain injury case histories, revealing that a significant proportion of TBI sufferers survive and recover most of the functions of daily living.

TL;DR: Findings indicate that exercise capacity is unaffected in concussed athletes who are asymptomatic at rest, however, their heart rate response to submaximal exercise is increased.

TL;DR: Two differing operational definitions of concussion are in the current use, involving the presence vs. absence of posttraumatic amnesia (PTA) and not clinically similar, although they are currently being widely treated as such.

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.
