Neurologist Michael S. Jaffee, MD, pens an article for The Conversation about sleep deprivation.
Newer research has suggested another important aspect of sleep for our brain: There is a system for the elimination of possibly harmful proteins such as abnormal variants of amyloid. This waste removal process, using what is known as the glymphatic system, relies on sleep to effectively eliminate these proteins from the brain. These are the same proteins found to be elevated in patients with Alzheimer’s disease. Studies show that older adults with less sleep have greater accumulations of these proteins in their brains.
