Stress Undermines Brain Circulation, Increases Dementia Risk
Summary: Researchers found that a rare class of neurons—type-one nNOS neurons—plays a central role in regulating brain blood flow and coordinating neural activity in mice. Removing these stress-vulnerable cells caused…
Low Choline Could Be a Hidden Driver of Anxiety
Summary: A large meta-analysis of 25 studies found that people with anxiety disorders have significantly lower levels of choline, a vital brain nutrient, compared to individuals without anxiety. This reduction…
