A new study of US adults suggests that drinking moderate amounts of caffeinated coffee may be a key factor in reducing the risk of dementia and promoting better cognitive health as people age. The research involved lengthy follow-up periods, up to 43 years, allowing scientists to examine how daily habits affect brain health over time. The study found that individuals who regularly consumed higher amounts of caffeinated coffee were less likely to develop dementia compared to those who rarely or never drank it. The strongest associations between coffee consumption and lower dementia risk emerged among people who drank two to three cups of caffeinated coffee per day. Interestingly, tea consumption was also linked to improved cognitive outcomes, but the amount associated with the greatest benefit was slightly lower than that for caffeinated coffee. While decaffeinated coffee did not show the same benefits as its caffeinated counterpart, this raises questions about whether caffeine itself plays a role in reducing dementia risk. The findings suggest that even small amounts of caffeine may have a significant impact on brain health over time. The study's data revealed striking differences in dementia rates between regular coffee drinkers and those who consumed little or no coffee. For example, among US adults who drank higher amounts of caffeinated coffee, researchers recorded 141 dementia cases annually for every 100,000 people, compared to 330 cases per 100,000 among those who rarely or never drank caffeinated coffee. Dementia is a complex condition characterized by progressive interference with memory, thinking, reasoning, and everyday activities. Alzheimer's disease is the most common cause of dementia, but several other brain disorders can also lead to it. As people age, occasional forgetfulness can become more noticeable. However, when cognitive difficulties severely disrupt daily life, they are considered a sign of dementia. Researchers are keenly interested in identifying lifestyle habits that may lower dementia risk, given the growing older population worldwide. The study suggests that regular consumption of caffeinated coffee may be one such habit linked to lower dementia risk. It's essential to note, though, that these findings indicate an association rather than a direct cause-and-effect relationship between coffee and dementia prevention. Other factors not yet explored could also contribute to the observed results. In addition to its potential impact on dementia risk, the study found that caffeinated coffee consumption was linked to better cognitive health overall. Specifically, participants who drank more caffeinated coffee were less likely to report subjective cognitive decline. Subjective cognitive decline refers to noticeable changes in memory or thinking abilities, even if not confirmed by formal testing. This can manifest as difficulty remembering information, concentrating, or finding the right words. Research has shown that people often notice changes in their cognitive abilities as they age, which can manifest as difficulty remembering information, concentrating, or finding the right words. These complaints do not necessarily indicate dementia, but they can provide valuable insights into how individuals perceive their own brain health. The study's findings suggest that participants who reported such difficulties may have been more likely to seek medical attention and participate in cognitive assessments. The data revealed a lower percentage of people with dementia risk among those who consumed caffeinated coffee regularly. This adds to the existing evidence linking moderate coffee consumption to healthier cognitive aging. To determine whether the amount of coffee consumed affects its benefits, researchers examined the relationship between coffee intake and dementia risk. They found that drinking two to three cups of caffeinated coffee per day was associated with the most favorable outcomes for brain health. The study's results also showed that the protective effects of moderate coffee consumption persisted even among individuals with a higher genetic risk of developing dementia. This suggests that genetics is only one factor influencing dementia, and that lifestyle choices like coffee consumption can play a significant role in mitigating its risks. Researchers found that drinking tea was also linked to lower dementia risk and better cognitive functioning, although the strongest associations appeared among participants who consumed one to two cups per day. The study did not distinguish between caffeinated and noncaffeinated tea, making it impossible to determine whether caffeine was responsible for the observed association among tea drinkers. This limitation underscores the complexity of studying the relationship between specific compounds and disease outcomes. In contrast, the results for coffee offered a clearer picture: regular caffeinated coffee was associated with lower dementia risk and better cognitive outcomes, but decaffeinated coffee did not demonstrate the same benefits. This difference raises questions about whether caffeine is the key factor driving the observed effects of moderate coffee consumption. Caffeine is a naturally occurring stimulant found in various plants, including coffee, tea, and certain others. It acts on the central nervous system to increase alertness and reduce feelings of tiredness, at least temporarily. The findings suggest that moderate consumption of caffeinated beverages like coffee and tea may be associated with healthier brain aging. Notably, two to three cups of coffee per day appeared to offer the strongest association, while one to two cups of tea showed more favorable results among tea drinkers. The study's findings suggest that moderate consumption of coffee and tea may have a beneficial effect on dementia risk. Notably, the research indicates that people who drink two to three cups of coffee per day are at lower risk for developing dementia, with similar results observed among tea drinkers consuming one to two cups daily. --- Source: [ScienceDaily Health](https://www.sciencedaily.com/releases/2026/11/261105224550.htm) Published by Noti Group: https://noti.group/coffee-consumption-linked-to-lower-dementia-risk/
