How does the brain clean itself during sleep? A new ultrafast MRI method tracks cerebrospinal fluid flow without contrast ...

Vascular dementia is a type of dementia that causes changes in memory, thinking, and behavior that result from conditions that affect the blood vessels in the brain. A person’s cognition and brain ...

A recent study found wearing a necktie could reduce blood flow to the brain. Researchers in Germany compared MRI results of a group of men wearing a necktie to those not wearing one. They found that ...

Sleep helps the brain to cleanse itself—and now this process can be measured in humans entirely noninvasively. Researchers at ...

Findings from Mass General Brigham investigators highlight the intricate interplay of diverse physiological processes as the brain shifts from wakefulness to sleep. A new study by investigators from ...

New neuroimaging research shows that when sleep-deprived people lose focus, the brain briefly shifts toward sleep-like physiology, offering fresh insight into why cognitive performance declines ...

Subtle changes in brain blood flow and oxygen use are closely linked to hallmark signs of Alzheimer’s, including amyloid plaques and memory-related brain shrinkage. Simple, noninvasive scans may one ...

Measuring blood flow in the brain is critical for responding to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. But existing techniques, ...

A negative mindset is known to trigger or heighten stress and anxiety — and new research has revealed other trickle-down effects on mental and physical health. Researchers from Amen Clinics, a ...

Restoring blood flow after an ischemic stroke can trigger secondary brain injury, causing inflammation, neuronal death, and long-term disability that current treatments do not address. Researchers ...

In a new study, people who followed a moderate-to-vigorous aerobic exercise routine for a year had a noticeable drop in brain age, while those who stuck to their usual fitness routine saw a slight ...

Now is the right time to outsmart age-related brain decline.
