Vestibular symptoms are persistent and problematic sequelae of blast exposure.
Several lines of evidence suggest that these symptoms often stem from injury to
the central nervous system. Current methods of assessing the vestibular system
have described vestibular deficits that follow traumatic brain injury and
differentiate blunt and blast trauma but have not examined the full range of
vestibular functions that depend on the cerebral structures above the midbrain.
Damage to the central vestibular circuits can lead to deficits in vital processes
of spatial perception and navigation, in addition to dizziness and
disequilibrium, and may also affect emotional functioning, particularly
noradrenergically modulated states of anxiety. Perceptual functions can be assessed to determine the extent of central nervous system involvement in vestibular symptoms and to provide greater confidence when vestibular dysfunction
is to be excluded. The ability to detect central vestibular dysfunction will significantly enhance our response to the dizziness and balance symptoms that are a common source of distress for Veterans.
