Our brain is an extremely complex and delicate organ. Our body fiercely protects it by holding onto things that help it and keeping harmful things out, such as bugs that can cause infection and toxins ...

Peter Searson is leading a Johns Hopkins University team that is unravelling how Alzheimer's and other diseases disrupt the blood-brain barrier, the complex interface that allows or blocks the passage ...

When a person first exhibits signs of having a stroke, the timing of treatment is critical to restore blood flow to the brain ...

The central nerve system (CNS) plays a crucial central regulatory role in mammalian life, and the blood-brain barrier is the most selective physical barrier protecting the brain by strictly ...

The right approaches are demonstrating that it is possible to breach the defensively designed blood-brain barrier despite its ...

Major advance promises to accelerate the understanding and improved treatment of a wide range of brain disorders, including stroke, cerebral vascular disorders, brain cancer, Alzheimer's disease, ...

The cells that line the blood vessels in our brains are highly selective. By deciding which molecules are allowed in and out of our most important organ, the barrier these cells form is critical for ...

Leakiness in the brain could explain the memory and concentration problems linked to long COVID. In patients with brain fog, MRI scans revealed signs of damaged blood vessels in their brains, ...

Exercise may sharpen the mind by repairing the brain’s protective shield. Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the ...

A model of a membrane called the blood–brain barrier could transform how scientists study drug delivery to the brain, as well as diseases of the brain’s vascular network. The model combines two ...

Repeated head knocks cause long-term damage to the delicate blood-brain barrier, potentially driving chronic traumatic encephalopathy (CTE), a neurodegenerative condition that affects some former ...

A new study shows exercise releases a liver enzyme that repairs aging brain blood vessels and restores memory.
