Abstract:
Vestibular-related problems (dizziness, vertigo, and imbalance) are common sequelae following concussion and blast exposures that result in mild traumatic brain injury (mTBI). However, the anatomical substrate connected to these dysfunctions is not well understood. To provide a better understanding of this area, we used voxel-based morphometry (VBM) as a platform for studying vestibular-related mTBI in the human brain. Briefly, VBM is a group comparison study which evaluates structural differences in magnetic resonance (MR) images between agematched groups of individuals (11 vestibular TBI patients and 10 controls). Using the VBM-8 Toolbox and statistical probability mapping (SPM), MRI images were segmented into gray matter, white matter, and cerebrospinal fluid, normalized into a standardized anatomical space, and then analyzed statistically for significant anatomical differences between groups. Based on the VBM analysis, most notable differences in brain anatomy were characterized by reductions in gray matter volume observed in the middle frontal gyrus, mesial frontal lobe, and in the insular area in the left mesial temporal lobe. These findings provide a preliminary analysis of distributed gray matter changes in key frontal and temporal areas of the brain associated with mTBI related vestibular dysfunction.
