This review asks the research question, “is the centripetal theory of concussion still valid today?” and works to answer the hypothesis that yes it is. To do so the methods include:​ 1) a review of the concept of CTC, 2) a review the pertinent literature, 3) applying the CTC to current biomechanics and pathophysiology and 4) proposing new concepts of concussion to deal with the changing nature of the contemporary definitions of concussion. The conclusion is that, although the concepts of the CTC remain valid after 40 years, the broadening of the definition of concussion requires that a wider perspective be taken regarding the term “concussion.” Currently, the term “cerebral” concussion for which the CTC was originally construed is being replaced by virtually any symptom arising after head motion whether it arises from the cerebrum or not. Thus, a Symptomcentric Concept of the Concussions is proposed whereby symptoms from various sites arise in response to a mechanical stimulation of the brain or other individual anatomic sources.
