South Korean researchers have, for the first time globally, identified the central pathway through which waste products exit the brain, proposing a new method for treating dementia. Jeong Eun-joo has the details. When we use our brains, a kind of waste product is generated. If this waste is not expelled from the brain and accumulates, it can damage nerve cells, leading to brain disorders including dementia. The problem has been that the major pathways for waste, including cerebrospinal fluid, to exit the brain were a mystery. South Korean researchers, however, have found the central pathway through which cerebrospinal fluid exits the brain. Cerebrospinal fluid collects in the lymphatic netw
