The space between the arachnoid and pia meningeal layers encasing the brain is a landscape of connective tissue, blood vessels, and cerebrospinal fluid. Scientists debate how that fluid moves within ...

Throughout the day and night, cerebrospinal fluid (CSF) pulses through small fluid-filled channels surrounding blood vessels in the brain, called perivascular spaces, to flush out neuroinflammation ...

Researchers have found that enlarged perivascular spaces in the brains of babies, caused by an accumulation of excess cerebrospinal fluid, have a 2.2 times greater chance of developing autism later in ...

The fluid-filled spaces around the brain's blood vessels need proper waste "clearance" every few hours. When that fails to happen, a baby's risk for autism appears to rise, new research shows. It's ...
