Consider treating acute blast-related concussion patients with N-acetyl cysteine (NAC) when starting within 72 hours after injury. For more chronic issues, in addition to family members, the best collateral source may be another service member with whom the patient has served. Evaluate carefully for post-traumatic stress disorder (PTSD), chronic pain, sleep disorders, balance, and hearing loss given that these are especially common in military personnel with concussion. Maintain confidentiality; if the patient has been using drugs and/or alcohol, it may be wise to refer them for rehabilitation discretely, because active duty military personnel do not have the same privacy protections that civilians have, and this can jeopardize their future careers. Return-to-duty decision-making is best done in collaboration with military physicians and occupational therapists. Refer to community resources specifically dedicated to wounded warriors.
