Choroid Plexus Enlargement in Patients with Chronic Migraine: Implications for Glymphatic System Dysfunction
Bibliographic record
Abstract
ABSTRACT Objectives: The choroid plexus produces cerebrospinal fluid, which is crucial for glymphatic system function. Evidence suggests that changes in the volume of the choroid plexus may be associated with glymphatic system function. Therefore, this study aimed to investigate alterations in choroid plexus volume in patients with migraines compared with healthy controls. Methods: We enrolled 59 patients with migraines (39 and 20 with episodic and chronic migraines, respectively) and 61 healthy controls. All participants underwent brain magnetic resonance imaging, including three-dimensional T1-weighted imaging. We analyzed and compared choroid plexus volumes between patients with episodic migraines, those with chronic migraines and healthy controls. Additionally, we evaluated the association between choroid plexus volume and the clinical characteristics of patients with migraine. Results: The choroid plexus volume in patients with chronic migraines was higher than that in healthy controls (2.018 vs. 1.698%, p = 0.002) and patients with episodic migraines (2.018 vs. 1.680%, p = 0.010). However, no differences were observed in choroid plexus volumes between patients with episodic migraine and healthy controls. Choroid plexus volume was positively correlated with age in patients with migraines (r = 0.301, p = 0.020) and in healthy controls (r = 0.382, p = 0.002). Conclusion: We demonstrated significant enlargement of the choroid plexus in patients with chronic migraine compared with healthy controls and those with episodic migraine. This finding suggests that chronic migraine may be associated with glymphatic system dysfunction.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
