A&D: caffeine consumption can reduce the risk of Alzheimer's disease

Researchers from the University of Lille conducted a study that revealed an interesting link between caffeine consumption and the risk of developing Alzheimer's disease. The findings were presented in Alzheimer's & Dementia, drawing the attention of the scientific community to the potential role of caffeine in the prevention of neurodegenerative diseases.

The study focused on patients over the age of 70 who already had mild cognitive impairment or early stages of Alzheimer's disease. Participants were divided into two groups based on the amount of caffeine they consumed. Analysis of the data showed that people who consumed less caffeine had a higher risk of cognitive and memory impairment. Moreover, the probability of developing Alzheimer's disease in this group was about 2.5 times higher compared to those who consumed more caffeine. The French scientists did not limit themselves to observing cognitive function alone. They carefully analyzed the proteins in the participants' cerebrospinal fluid. This study revealed significant differences in the ratios and amounts of certain forms of beta-amyloid proteins between the groups. People with lower caffeine intake had lower concentrations of these proteins in their cerebrospinal fluid, which may indicate that they are higher in the brain. This finding is considered a biological marker of neurodegeneration characteristic of Alzheimer's disease.

While the study emphasizes the potential benefits of caffeine for older adults, it is important to note that it does not establish a direct causal link between coffee consumption in middle age and the risks of developing Alzheimer's disease in old age. Nevertheless, this study adds an important touch to the growing body of scientific work suggesting that moderate consumption of coffee and other caffeine-containing products may help preserve cognitive function and increase longevity.
