Examining Associations Between Environmental Exposures and Neurobehavioral Symptoms in Post-9/11 Veterans With a Probable History of TBI

Prior research has established several risk factors for poor neurobehavioral outcomes after traumatic brain injury (TBI) in Iraq/Afghanistan-era-Veterans. However, no studies have examined the impact of environmental exposures on neurobehavioral symptoms in this population....

No immediate change to audiology practice is warranted; findings are associational and the audiology-specific tinnitus data are secondary to broader neurobehavioral outcomes, but the study reinforces screening for tinnitus in TBI veterans with known environmental exposures.

Understanding environmental exposure as a compounding factor in veteran TBI and hearing-related symptoms could refine how audiologists and VA clinicians screen and prioritize this high-prevalence patient group.

1. 01Study published in J Head Trauma Rehabil focusing on post-9/11 veterans with probable TBI.
2. 02Examines links between environmental hazards (e.g., burn pits, toxins) and neurobehavioral symptoms.
3. 03Tinnitus may be among the neurobehavioral symptoms assessed, reflecting dual audiological-neurological burden.
4. 04Associational design limits causal conclusions about any specific exposure-symptom relationship.
5. 05Findings support interdisciplinary care integrating audiology within veteran TBI rehabilitation programs.
