Scientists have discovered that a common type of stroke may have a very different cause than doctors once thought. Instead of fatty plaque clogging arteries, the strongest link was found with enlarged ...

Blood vessels in the brain are highly interconnected and efficient in actively regulating blood flow. Yet, the mechanisms that regulate flow are not well studied on a holistic level. To determine how ...

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 ...

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 ...

A study recently published in Nature has identified a key factor in the age-related breakdown of the blood-brain barrier (BBB) and has demonstrated that this damage may be reversible, potentially ...

Scientists have discovered that a part of the brain may be behind high blood pressure. The lateral parafacial region sits in the brainstem – the oldest part of the brain – which controls automatic ...

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 ...
