How does caffeine influence human behavior when tasks seem impossible? A new study suggests it may help people persist during stressful situations. The research bridges animal models of coping with human motivation and performance.

Despite concerns about caffeine's effects on young brains, researchers found no evidence that recent or regular consumption influences the relationship between two brain networks linked to attention in early adolescents.

Seniors who regularly consume caffeine may be less prone to cognitive decline, according to a new study. The findings reveal a dose-dependent relationship, with higher caffeine intake linked to significantly lower odds of poor cognitive performance.

Think you can sleep fine after a late coffee? A new study suggests otherwise. Researchers found that while caffeine may not prevent sleep, it creates a "shallower" rest by increasing brain complexity and pushing it toward a more wake-like state.

Caffeine may help prevent stress-induced depression-like symptoms in mice by protecting gut health and reducing inflammation. While more research is needed, the findings raise the possibility that everyday dietary habits could play a meaningful role in mental health

Drinking coffee might wake you up even without the caffeine. Researchers found that habitual coffee drinkers responded similarly to both regular and decaf coffee, pointing to the influence of expectation and ritual on alertness and brain activity.

Caffeinated coffee improved strength and sprint performance in trained men, regardless of chronotype or time of day.

New evidence suggests 1-MX, derived from caffeine, may enhance learning and protect the brain from age-related decline.

A new study finds drinking caffeinated coffee slightly changes how older adults maintain balance but does not significantly affect stability or physical function. A strong cup of coffee is unlikely to increase fall risk.

Slow caffeine metabolizers excel in emotion recognition with high caffeine intake, while fast metabolizers perform better in executive function tasks with moderate caffeine consumption.

Consuming unsweetened caffeinated coffee is linked to a lower risk of Alzheimer’s, Parkinson’s, and related mortality, while sweetened or artificially sweetened coffee showed no such benefits.

A Spanish study found that 6 mg/kg of caffeine improved reaction time but caused nervousness and increased energy, while 3 mg/kg had no effect.
