Background: Mild traumatic brain injury (mTBI), or concussion, is the most common presentation of TBI in the emergency department (ED), but a diagnosis of mTBI may be missed in patients presenting with other acute injuries after a motor vehicle collision (MVC).
Objective: To estimate the frequency of missed diagnoses of mTBI in patients seen in the ED after MVC who later developed chronic pain syndromes.
Study Design: Retrospective cohort study.
Article Synopsis
- Mild traumatic brain injury can significantly alter brain activity, leading to distinct changes in neurotransmission and oscillations in patients with post-concussive syndrome and chronic pain.
- A study involving 57 affected patients and 54 controls utilized advanced electroencephalography and machine learning techniques to analyze brain wave patterns and identify differences.
- Results showed that patients had increased delta and theta power and decreased alpha power, with findings strongly correlating with symptom duration and offering a high predictive classification accuracy for distinguishing between patient and control groups.
Background: Transcranial direct current stimulation (tDCS) is a safe, tolerable, and acceptable technique in adults. However, there is limited evidence for its safety in youth. Although limited, there are a handful of important empirical articles that have evaluated safety and tolerability outcomes in youth.

The paper by Bennabi and Haffen ( , ) was an important step towards the formal acceptance of transcranial direct current stimulation (tDCS) as a possible form of therapy. Their review demonstrated favourable support for the beneficial effects of tDCS for MD, coupled with necessary practical considerations, such as its relatively low cost, portability/ease of use in clinical settings, non-invasiveness, and good tolerability.

To facilitate translation into clinical practice, we interviewed parents of children who have experienced experimental tDCS. A grounded theory approach using open, axial, and selective coding provided seven emergent themes for acceptability: tDCS provides hope for parents, safety tolerability and side effects of tDCS versus medication, burden of treatment, education and trust with care providers, cost and coverage, unestablished tDCS efficacy versus established medication effectiveness, perceived compliance of tDCS versus medication.
View Article and Find Full Text PDFBackground: The polytrauma clinical triad (PCT) is a complex disorder composed of three comorbid diagnoses of chronic pain, post-traumatic stress disorder (PTSD), and postconcussion syndrome (PCS). PCT has been documented in veterans returning from deployment, but this is the first report on PCT prevalence in nonmilitary personnel after a motor vehicle collision (MVC).
Methods: Data were drawn from routine intake assessments completed by 71 patients referred to a community-based clinic for chronic pain management.
