The increased size of, and lesser blood supply to, a key brain structure in patients with Long COVID tracks with known blood markers of Alzheimer's disease and greater levels of dementia, a new study ...

A choroid plexus cyst is a buildup of fluid found in the choroid section of an unborn baby’s brain. It’s estimated that choroid plexus cysts happen in about 2% of pregnancies, usually during the ...

Choroid plexus tumors are growths in the area of the brain that produces cerebrospinal fluid (CSF). They may be cancerous or noncancerous. Choroid plexus tumors are rare. They develop in the choroid ...

OAK BROOK, Ill. – Increased volume of an important structure in the brain called the choroid plexus is linked to greater cognitive impairment and Alzheimer’s disease, according to a new study ...

New work offers an unprecedented real-time view of the choroid plexus in a mouse model, providing a glimpse of how disturbances of the mother's immune system during pregnancy disrupt the developing ...

Once viewed merely as a producer of the cerebrospinal fluid (CSF) bathing the brain and spinal cord, the choroid plexus is now known to be a key player in brain development and immunity. These fronds ...

Deep in the brain, sheets of tissue known as the choroid plexus produce cerebrospinal fluid (CSF) and act as a protective barrier between the brain and CSF. But the lab of Maria Lehtinen, Ph.D., at ...

A longitudinal, observational study found that the choroid plexus, a network of blood vessels in each ventricle of the brain, plays a potential role in the neurodegenerative and chronic inflammatory ...

Floating in fluid deep in the brain are small, little understood fronds of tissue. Two new studies reveal that these miniature organs are a hotbed of immune system activity. This activity may protect ...
