Severe Post-MVA Injuries That Can Be Challenging to Diagnose (Pt. 4)

This article focuses on the clinical progression from post-concussion syndrome (PCS) to post-traumatic stress disorder (PTSD) following a motor-vehicle accident (MVA). It explains that PCS, a form of mild traumatic brain injury (mTBI), can result from blunt-force trauma or acceleration-deceleration forces causing diffuse axonal injury, often without visible head trauma. PCS is diagnosed when concussion symptoms like headache, dizziness, and fatigue persist beyond two weeks, potentially accompanied by issues like photophobia, memory impairment, and irritability. The author emphasizes the significant symptom overlap between PCS and PTSD, including hyperarousal, sleep disturbances, and poor concentration, noting that the two conditions can co-occur and exacerbate one another. The prolonged recovery from physical MVA injuries can reinforce the "trauma memory" that contributes to PTSD. To aid in diagnosis and documentation, the article recommends clinical tools like the Acute Concussion Evaluation (ACE) and post-concussion questionnaires. It concludes by stressing the need for early identification and interprofessional co-management with neurologists and psychotherapists to address both the physical and psychosocial aspects of the patient's recovery, which is critical for achieving an effective outcome.
