What Researchers Did
Researchers compared neuropsychological assessments between U.S. military service members with mild traumatic brain injury (mTBI) only (n=36) and those with mTBI plus post-traumatic stress disorder (PTSD) (n=35) from a randomized interventional study.
What They Found
The mTBI group reported worse symptoms than published norms, with over 50% showing abnormal scores on PCS, PTSD, and pain scales. The mTBI+PTSD group exhibited significantly worse symptom reporting (mean NSI total score 39.9 vs. 27.5, p<0.001) and performed worse on cognitive tasks like digit span (mean difference -1.5, p=0.04) and Grooved Pegboard (dominant hand mean difference -7.0, p=0.003) compared to the mTBI-only group.
What This Means for Canadian Patients
Canadian patients experiencing mTBI with co-occurring PTSD may face more severe symptoms and cognitive challenges, underscoring the need for comprehensive evaluation. Early identification of PTSD in mTBI patients could enable tailored interventions, potentially improving treatment outcomes and overall quality of life.
Canadian Relevance
This study was conducted with U.S. military service members and does not have a direct Canadian connection.
Study Limitations
The findings are based on a specific population of U.S. military personnel, which may limit their generalizability to broader patient populations.
