Loss of Glymphatic Drainage of Cerebrospinal Fluid Correlates with Alzheimer's Disease Progression

A magnetic resonance imaging (MRI) approach known as diffusion tensor image analysis along the perivascular space (DTI-ALPS) can be used to measure the flow of cerebrospinal fluid leaving the brain via the glymphatic system, a network of vessels that parallels blood vessels passing out of the brain. This drainage of cerebrospinal fluid allows metabolic waste...
