TL;DR
Researchers at Monash University and Yale School of Medicine are collaborating to create non-invasive devices intended to increase pumping of neck lymphatic vessels to accelerate clearance of waste from the brain after ischemic stroke. The effort builds on Yale findings linking improved brain lymphatic function to better recovery and highlights potential relevance to Alzheimer’s and other neurodegenerative conditions.
What happened
Monash University researchers, working with colleagues at Yale School of Medicine, announced a joint effort to design high-tech, non-invasive devices aimed at enhancing the brain’s natural drainage pathways following ischemic stroke. The project focuses on the set of lymphatic routes that remove excess fluid and toxic waste from the brain; dysfunction in this system has been associated with Alzheimer’s disease and other neurological and neurodegenerative diseases. Yale investigators originally reported that boosting the function of those brain-draining lymphatics can improve recovery after ischemic stroke. Monash’s Institute of Pharmaceutical Sciences (MIPS) and Yale faculty — including Anne Eichmann, Lindsay McAlpine and Jean-Leon Thomas — are developing devices intended to help lymphatic vessels in the neck pump more effectively, with the goal of increasing waste clearance in the immediate period after a stroke, when interventions are most time-sensitive. The announcement was posted by Monash on 2 December 2025.
Why it matters
- Faster removal of excess fluid and toxic metabolites after stroke could influence acute recovery pathways and outcomes.
- The approach targets a physiological drainage system implicated in Alzheimer’s and other neurodegenerative diseases, suggesting possible broader applications.
- Non-invasive devices could be deployed quickly after stroke onset, a period when treatments must act rapidly to be effective.
- If validated, enhancing lymphatic clearance offers a mechanistically distinct strategy from therapies that target neurons or blood flow directly.
Key facts

Quick glossary
- Brain-draining lymphatics: A network of vessels and pathways that help remove fluid and metabolic waste from brain tissue.
- Ischemic stroke: A type of stroke caused by a blood clot blocking an artery that supplies blood to part of the brain.
- Neurodegenerative disease: A disorder characterized by progressive loss of structure or function of neurons, such as Alzheimer’s disease.
- Non-invasive device: A medical device intended to affect physiological function without surgery or entry into the body.
- Lymphatic vessel: A tubular structure that transports lymph, a fluid containing immune cells and metabolic byproducts, through the lymphatic system.
