Neck cancer surgery research article examining how removing cervical lymph nodes might affect brain fluid drainage and cognitive health; a clinical and mechanistic investigation inviting readers to learn about the study design and implications.

Key Takeaways
- In a retrospective cohort of 1,035 patients, 18% under age 65 developed cognitive impairment within two years after neck lymphadenectomy without chemo or radiation.
- Longitudinal MRI from 59 patients showed accelerated enlargement of the temporal horn ventricles after cervical lymph node resection, especially after bilateral dissection.
- Preclinical models found acute cervical lymphatic blockage caused oxidative stress, neuroinflammation, and synapsin protein aggregation distinct from amyloid or tau pathology.
