A paramount review of concussions and their “long-term” effects has been published (or soon will) in Nature Reviews Neurology that I certainly hope does not slip past the masses. Not only is the information somewhat of a “where we stand”-moment of clarity, it is authored by a very underrated and proficient researcher; Dr. Barry D. Jordan.
Acute and chronic sports-related traumatic brain injuries (TBIs) are a substantial public health concern. Various types of acute TBI can occur in sport, but detection and management of cerebral concussion is of greatest importance as mismanagement of this syndrome can lead to persistent or chronic postconcussion syndrome (CPCS) or diffuse cerebral swelling. Chronic TBI encompasses a spectrum of disorders that are associated with long-term consequences of brain injury, including chronic traumatic encephalopathy (CTE), dementia pugilistica, post-traumatic parkinsonism, post-traumatic dementia and CPCS.
Dr. Jordan also discussed CTE in further detail including the limitations of possible antemortem detection; including imaging and categorization.
In this Review, the spectrum of acute and chronic sport-related TBI is discussed, highlighting how examination of athletes involved in high-impact sports has advanced our understanding of pathology of brain injury and enabled improvements in detection and diagnosis of sport-related TBI.
The overriding theme I gathered from this review article is one that I have been hammering home for a very long time: the mismanagement of the original sequale may be the largest factor in discussion the multiple faces of “chronic TBI” that result from concussion. This paper is also very succinct in demonstrating the massive amount of work that still needs to be done.
I urge you to find a copy or pay for a subscription for this article, it should be one that we look back on in 5 years as the “where have we come from” moment in this issue, regarding chronic issues from sports related concussion.
