Caffeine, Not Coffee, Shields Mouse Brains From Chronic Stress
A new study in mice shows that caffeinated coffee protects against stress-induced memory loss and mood deterioration, while decaffeinated coffee offers no such benefits. Published in Neurobiology of Stress, the research suggests caffeine is the primary active ingredient responsible for these protective effects. Mice drinking regular coffee maintained normal brain function and behavior despite chronic stress, whereas those drinking decaf exhibited significant deficits similar to those drinking plain water. These findings clarify the role of caffeine in mental health resilience, distinguishing it from other coffee compounds.
