Background
Traumatic brain injury (TBI) has substantial negative implications for the post-deployment adjustment of Veterans who served in Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF); however, most research on Veterans has focused on males. This study investigated gender differences in psychiatric diagnoses and neurobehavioral symptom severity among OEF/OIF Veterans with deployment-related TBI.
Methods
This population-based study examined psychiatric diagnoses and self-reported neurobehavioral symptom severity from administrative records for 12,605 United States OEF/OIF Veterans evaluated as having deployment-related TBI. Men (n = 11,951) and women (n = 654) who were evaluated to have deployment-related TBI during a standardized comprehensive TBI evaluation in Department of Veterans Affairs (VA) facilities were compared on the presence of psychiatric diagnoses and severity of neurobehavioral symptoms.
Findings
Posttraumatic stress disorder (PTSD) was the most common psychiatric condition for both genders, although women were less likely than men to have a PTSD diagnosis. In contrast, relative to men, women were 2 times more likely to have a depression diagnosis, 1.3 times more likely to have a non-PTSD anxiety disorder, and 1.5 times more likely to have PTSD with comorbid depression. Multivariate analyses indicated that blast exposure during deployment may account for some of these differences. Additionally, women reported significantly more severe symptoms across a range of neurobehavioral domains.
Conclusions
Although PTSD was the most common condition for both men and women, it is also critical for providers to identify and treat other conditions, especially depression and neurobehavioral symptoms, among women Veterans with deployment-related TBI.
Abstract-The frequencies of hearing impairment (HI), vision impairment (VI), or dual (hearing and vision) sensory impairment (DSI) in patients with blast-related traumatic brain injury (TBI) and their effects on functional recovery are not well documented. In this preliminary study of 175 patients admitted to a Polytrauma Rehabilitation Center, we completed hearing and vision examinations and obtained Functional Independence Measure (FIM) scores at admission and discharge for 62 patients with blast-related TBI. We diagnosed HI only, VI only, and DSI in 19%, 34%, and 32% of patients, respectively. Only 15% of the patients had no sensory impairment in either auditory or visual modality. An analysis of variance showed a group difference for the total and motor FIM scores at discharge (p < 0.04). Regression model analyses demonstrated that DSI significantly contributed to reduced gain in total (t = -2.25) and motor (t = -2.50) FIM scores (p < 0.05). Understanding the long-term consequences of sensory impairments in the functional recovery of patients with blast-related TBI requires further research.
Our preliminary results showed that posttraumatic stress disorder and pain significantly contributed to sleep disturbance. When traumatic brain injury or pain coexisted with posttraumatic stress disorder, sleep problems worsened. In this clinical population, where the majority of traumatic brain injury diagnoses tend to be in the mild category, traumatic brain injury alone did not predict sleep disturbance. Through increased awareness of pain, posttraumatic stress disorder, and traumatic brain injury, clinicians can work collaboratively to maximize rehabilitation outcomes.
