A study published in Brain shows that fragmented sleep damages brain blood vessels by affecting pericytes, which may increase the risk of dementia and cognitive decline, highlighting the importance of sleep health for brain vascular integrity.
A 75-year-old woman experienced her first seizure, with tests showing no tumors or aneurysms, and her doctor suggests age-related small blood vessel disease as a possible cause, possibly linked to past severe flu or blood pressure issues. Further evaluation by a neurologist is recommended to determine the cause and appropriate treatment, with many cases in older adults being due to blood vessel changes.
A lab study suggests that erythritol, a common zero-calorie sweetener found in many sugar-free products, may impair brain blood vessel cell function by increasing oxidative stress and disrupting protective pathways, potentially raising stroke risk. However, the research was conducted in cells over a short period and does not prove causation in humans, highlighting the need for further studies.
Research indicates that erythritol, a common sugar substitute, may impair brain blood vessel cell function by increasing oxidative stress and disrupting nitric oxide signaling, potentially elevating stroke risk, though further studies are needed.
Researchers have discovered that blood vessels in the brain develop under unique rules, involving a specific enzyme crucial for their invasion into the brain and the establishment of the blood-brain barrier. This finding challenges previous beliefs about vascular formation and offers new possibilities for targeted treatments of neurological diseases by manipulating the mechanisms governing cerebral blood vessels. The study sheds light on brain-specific angiogenesis and the role of Wnt7a/b ligands in controlling this process, providing insights into organ-specific angiogenesis mechanisms.
