Researchers have made a shocking finding about vessels that connect the brain to the immune system. Previously thought not to exist, the discovery of these vessels may be related to diseases including autism, Alzheimer’s and multiple sclerosis. Until now, there has never been a lymphatic system for the central nervous system, which will alter the way that the central nervous system relates to the immune system. The discovery of the lymphatic vessels begs numerous questions regarding brain functioning and diseases that affect it, such as Alzheimer’s disease where scientists may be able to look at the role these vessels play in aging as another area to explore and find answers. Aside from that, there are a multitude of neurological diseases, from autism to multiple sclerosis, that need take into consideration the new discovery as something that scientists previously did not know were present.
