Abstract: In some embodiments herein, methods, compositions, and uses for countering the effects of aberrant meningeal lymphatic drainage and/or modulating lymphatic vessels of the central nervous system are described. In some embodiments, methods, compositions, or uses for treating, preventing, or ameliorating symptoms of a neurodegenerative disease associated with aberrant meningeal lymphatic drainage are described. Modulating lymphatic vessels, or countering the effects of aberrant meningeal lymphatic drainage, in accordance with some embodiments, are used to diagnose, treat, prevent, or ameliorate symptoms of neurodegenerative diseases such as Alzheimer's disease (AD) and dementia. Methods of diagnosing and monitoring the progression of neurological diseases are also provided.
