Since the 1940s, dizziness, vertigo, and imbalance have been well documented and commonly reported sequelae of traumatic brain injury (TBI) (Maskell et al. 2006). While long recognized, the complex relationship between dizziness and TBI remains incompletely understood. "Dizziness" in itself is a nonspecific term that may encompass a wide variety of symptoms, including vertigo, imbalance, disequilibrium, light-headedness, altered coordination, and disorientation. Entangled and often inseparable, these symptoms represent a complex continuum of sequelae that cross vestibular, cognitive, and psychosocial domains. This broad spectrum of symptomatology gives some insight into the diversity of pathology present in the TBI patient. It is both the diversity and complexity of injuries that pose unique diagnostic and treatment challenges to the clinician.
