Pain and sleep in post-concussion/mild traumatic brain injury
Bibliographic record
Abstract
Concussion after a force to the head is called mild traumatic brain injury (mTBI). Approximately 1 in 5 patients with mTBI will develop chronic pain (headache and widespread pain, possibly of central origin) and/or sleep problems (insomnia, disordered breathing, periodic limb movements). However, the predisposing mechanisms for chronic pain in patients with mTBI are unknown. Mild traumatic brain injury is a rare model to prospectively assess the risk factors and mechanisms for pain chronification from the injury onset in the absence of pretrauma comorbidity or medication. In the acute phase, headaches and sleep disturbances seem to predict the poorest long-term cognitive and mood outcomes. Although recent studies suggest that certain brain biomarkers and mood alterations (eg, anxiety, depression) contribute, the causality of chronic pain remains unclear. In mTBI patients with pain, poor sleep quality was correlated with fast beta and gamma electroencephalographic activity in frontal, central, and occipital electroencephalographic (EEG) derivations in all sleep stages. Sleep recuperative function seems to be disturbed by persistent wake EEG activity, corroborating patient complaints such as feeling awake when asleep. Pain and sleep management in mTBI is not yet evidence-based. Treatments include cognitive behavioral and light therapies, medications, and continuous positive airway pressure (CPAP) or oral appliances for disordered sleep breathing. Customized approaches are indicated for mTBI, pain, and sleep complaints. Further studies in pediatric, sport, and transportation populations are needed to prevent TBI chronification. Improvements are emerging in biomarker sensitivity and specificity and management strategies for TBI, pain, and sleep comorbidities.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
