Delayed-Onset Neuropathological Complications From a Foramen Magnum and Occipital Crest Focused TBI of the Vietnam War and Other Conflicts: Part III, Critique of Existing TBI Criteria and Their Operational Controversies.

Introduction: In this report, we discuss the controversy of the diverse traumatic brain injury (TBI) categorization and taxonomy and the need to develop a new multidimensional and multidisciplinary categorization system that can be an aid in improved diagnostic and prognostic outcomes. Of interest, the heterogeneity of TBI marks the major obstacle to develop effective therapeutic interventions. Currently, the Glasgow Coma Scale has been utilized to guide in the prognosis and clinical management of TBI; it does not encompass the pathophysiological mechanisms leading to neurological deficits that can impede therapeutic interventions and consequently the failure of clinical trials.

Delayed-Onset Neuropathological Complications From a Foramen Magnum and Occipital Crest Focused Traumatic Brain Injury of the Vietnam War and Other Conflicts: Part I, Case Report.

Introduction: The diagnosis of traumatic brain injuries is typically based on hemispheric blasts resulting in degrees of unconsciousness and associated cerebral injuries. This case report describes a Vietnam War era setting in which a traumatic blast wave struck the posterior cranium in the region of the foramen magnum, occipital crest, and other skull openings (orbit, oronasal, and ear) and the unique secondary clinical signs and symptoms experienced over time.

Materials And Methods: This case report describes secondary delayed-onset clinical signs and symptoms consistent with progressive decades-long physical and functional complications.

Delayed-Onset Neuropathological Complications From a Foramen Magnum and Occipital Crest-Focused Traumatic Brain Injury of the Vietnam War and Other Conflicts: Part II, Research Analysis.

Introduction: Much of the research impacting diagnosis, outcome, and treatment of traumatic brain injuries (TBIs) has favored time of consciousness criteria indicative of hemispheric blast focus alone. However, recent animal-based research has widely expanded the diagnostic knowledge base and potential treatment options.

Methods: Recent animal-based research findings of foramen magnum and occipital crest-focused blast injuries in laboratory rats were reviewed and compared to the Part I human case report.
