Researchers found that caffeine blocks alcohol’s ability to increase dopamine in brain reward areas, potentially reducing alcohol's rewarding effects. This suggests caffeine could play a role in preventing or treating alcohol addiction.

Research found no causal link between moderate coffee intake during pregnancy and children’s neurodevelopmental issues, supporting guidelines that low to moderate caffeine consumption (under 200mg daily) is safe for expectant mothers and their babies.

Adding coffee polyphenols to the diets of male mice exposed to early-life stress improved cognitive function and increased microglia survival, suggesting a potential nutritional intervention for mitigating stress-induced cognitive deficits.

Caffeine may worsen brain grey matter loss during sleep deprivation, potentially hindering recovery and exacerbating the negative effects of chronic sleep restriction, new research reveals.

A new study has found that coffee consumption is heritable, with specific genes influencing how much coffee people drink and its association with other substance use behaviors.

A recent study found that a combination of creatine nitrate and caffeine significantly improves cognitive function in resistance-trained males.

Coffee drinkers have a significantly lower risk of developing Parkinson’s disease, with the highest consumers nearly 40% less likely to develop the condition compared to non-drinkers.

A study has found that adding caffeine to the drinking water of rats exposed to social isolation stress can protect them from developing memory impairments.

Researchers discovered that while a single dose of caffeine can improve attention in sleep-deprived individuals, regular high consumption of caffeine leads to diminished attentional performance, as well as alterations in brain activity.

Chronic caffeine use may reduce brain plasticity, key to learning and memory, according to a study. This contrasts with expectations of caffeine enhancing cognitive abilities.

Drinking moderate amounts of coffee or tea can decrease the risk of cognitive disorders such as dementia, according to a recent study published in Nutrition Reviews.

Regular consumption of tea and coffee containing caffeine could lower the risk of Parkinson's disease in Asians with specific LRRK2 gene variants. This finding, from a study involving 4,488 participants, points to potential preventative strategies for at-risk populations.

Recent research in Scientific Reports suggests that daily caffeine intake might impair rather than improve working memory. While previous studies highlighted caffeine's acute benefits for attention and alertness, this research focused on the long-term effects of sustained caffeine consumption on...
