Discovery of Human Brain Lymph Vessels Offers Alzheimer’s Researchers New Possibilities
In a discovery that might provide an entirely new angle to Alzheimer’s disease research, scientists have mapped lymphatic vessels to the outside of the brains of living humans. Because these vessels are the main route traveled by immune cells, the finding, described in the journal eLife, may allow scientists to study if, and how, immune processes are involved in the neurodegenerative condition. But lymphatic vessels also are used for removing waste, a process that may have implications for Alzheimer's. Until a few years ago, it was a generally accepted notion that the brain lacked lymphatic vessels. In fact, the brain was long considered “immune-privileged,” meaning that immune processes did not take place there as they did in the rest of the body. But in 2015, two independent research groups reported that lymph vessels, indeed, were present in the membranes surrounding the brain in rodents. The study, “Human and nonhuman primate meninges harbor lymphatic vessels that can be visualized noninvasively by MRI,” took this knowledge one step further, showing that these vessels also exist in monkeys and humans. They also described imaging methods, commonly used for other purposes, which could allow researchers to study the vessels in living people. To visualize the vessels, the team at the National Institute of Neurological Disorders and Stroke (NINDS) at the National Institutes of Health used magnetic resonance imaging (MRI) together with different dyes. One of these dyes could leak out from blood vessels in a brai

    The discovery also suggests that lymph nodes may be used to drain fluid from the brain in the same way they do in other organs.
    “For years we knew how fluid entered the brain. Now we may finally see that, like other organs in the body, brain fluid can drain out through the lymphatic system,” Reich said.
    And with this comes the possibility that the vessels are used to transport waste out of the brain.

    why would it be any different?….the waste is hanging up in the neck and shoulders …break it up there and NO MORE ALZ.
    It’s a mechanical problem !!!
