Replacing a missing brain lipid may calm overactive blood vessels and restore healthy blood flow—opening a new path toward treating dementia.

Healthy brain function relies on a steady supply of blood. Disruptions in blood flow are linked to major neurological conditions like stroke, Alzheimer's disease (AD), and traumatic brain injuries.

A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a ...

For the first time, scientists have used real-time imaging to track tiny pieces of microplastics as they moved through the brain blood vessels of mice. In experiments, the international team of ...

A new study identifies molecular factors that promote small vessel disease—and an active drug that can restore impaired ...

Reduced levels of a critical protein are linked to devastating brain diseases like Alzheimer's, frontotemporal dementia, and amyotrophic lateral sclerosis (ALS). Surprisingly, the protein shortage ...

As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer’s disease and ...
