Influence of bodily injuries on symptom reporting following uncomplicated mild traumatic brain injury in US military service members.
: To examine the relations among bodily injuries, traumatic stress, and postconcussion symptoms in a sample of combat-injured US service members who sustained a mild traumatic brain injury. ⋯ : While it might be expected that greater comorbid physical injuries would be associated with greater symptom burden, in this study as the severity of bodily injuries increased, symptom burden decreased. Hypothesized explanations include: underreporting of symptoms; increased peer support; disruption of fear conditioning due to acute morphine use; or delayed expression of symptoms.
