31. Lymph And Mind: A New Perspective on Cognitive Dysfunction in Lymphedema
Bibliographic record
Abstract
PURPOSE: Lymphedema and cognitive impairment were once thought to be unrelated. However, recent discoveries of brain lymphatics and the systemic nature of primary lymphedema suggest a possible connection. Given frequent patient reports of cognitive impairment, this study investigates the relationship between primary lymphedema and cognitive dysfunction. METHODS: We assessed cognitive function in 81 patients with primary lymphedema (67 females, 14 males; mean age 45) using the Montreal Cognitive Assessment (MoCA) and Brain Fog Scale (BFS). A comparative analysis was conducted against a historical control group of 1,046 healthy individuals. A subgroup analysis compared cognitive scores of patients who underwent lymphatic reconstruction (n=12) with those who did not (n=69). Statistical differences between groups were evaluated using independent t-tests. RESULTS: Primary lymphedema patients had an average BFS score of 28.10±18.92 and a mean MoCA score of 27.92±2.28. Compared to controls, they showed significantly higher brain fog symptoms, including mental fatigue (10.58±5.44 vs. 8.62±4.63, p=0.0022), impaired cognitive acuity (10.57±8.44 vs. 7.81±6.18, p=0.0050), and confusion (6.95±6.56 vs. 5.18±5.71, p=0.0203). Patients with subjective cognitive complaints (n=21) had significantly higher BFS scores across all domains than those without (p<0.0001). Furthermore, patients who underwent lymphatic surgery reported lower brain fog symptoms, particularly in cognitive acuity (6.25±5.22 vs. 11.32±8.69, p=0.011) and total BFS score (19.75±11.87 vs. 29.55±19.59, p=0.027). CONCLUSION: This study identifies a significant correlation between primary lymphedema and cognitive impairment. Post-surgical cognitive improvements suggest a mechanistic link between lymphatic function and cognitive performance, emphasizing the systemic nature of lymphedema and the necessity for cognitive assessments in affected patients.

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.
