A major international study has uncovered a new biological clue that could help predict dementia long before memory problems arise. Researchers from the University of Cambridge and Zhejiang University ...

Sleep helps the brain to cleanse itself—and now this process can be measured in humans entirely noninvasively. Researchers at ...

Dementia has long been framed as a slow, irreversible loss of neurons, but a new line of research is shifting attention to the blood vessels that feed the brain. Scientists are now testing whether ...

How does the brain clean itself during sleep? A new ultrafast MRI method tracks cerebrospinal fluid flow without contrast ...

This Collection welcomes studies of the dynamics of cerebrospinal fluid and cerebral circulation in health and disease. In addition to protecting the brain, and spinal cord, from impact and injury, ...

The clinical syndrome produced by a stroke is determined by the artery or arteries that are occluded. Blood is supplied to the brain by two major sets of arteries, the anterior and posterior ...

A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation ...
