The limbic system helps regulate emotional and social processing, as well as learning, motivation, and memory. It consists of structures that lie beneath the outer, wrinkly part of the brain and above ...

Impaired glymphatic function — the brain’s waste clearance system — could help explain how cardiovascular disease (CVD) risk factors may drive dementia. In a large UK Biobank study, MRI markers of ...

It’s been known for millennia that the human body accumulates waste as a result of day-to-day functioning, but it’s now recognized that the awake, active brain also builds up waste that negatively ...

Aging compromises the lymphatic vessels surrounding the brain, disabling waste drainage from the brain and impacting cognitive function. Researchers boosted lymphatic vessel integrity in old mice and ...

As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer's disease and ...

Scientists have restored the brain's waste-clearing process in aging mice, offering potential new treatment for Alzheimer's and Parkinson's using existing drugs. Alzheimer's, Parkinson's, and other ...

Our bodies rely on their lymphatic system to drain excessive fluids and remove waste from tissues, feeding those back into the blood stream. It’s a complex yet efficient cleaning mechanism that works ...
