Can Coffee Consumption Slow Down Cognitive Decline?
Good news for those who start their day with a cup of coffee: a recent study has shown that regular coffee consumption has been linked to a reduced risk of Alzheimer’s disease.
Research from a team at Edith Cowan University in Australia suggests that coffee drinking lowers the risk of developing Alzheimer’s disease. The long-term data collected as part of the research project “Australian Imaging, Biomarkers and Lifestyle Study of Aging” shows that people who drink coffee regularly are less likely to develop Alzheimer’s than people who do not drink coffee. The study results were recently presented in the renowned journal “Frontiers in Aging Neuroscience”.
Can Coffee Drink Slow Down Cognitive Decline?
Among other things, it has been observed for over a decade whether coffee consumption affects the rate of cognitive decline. According to the head of the study, Dr. Samantha Gardener found a link between coffee and several key markers in Alzheimer’s disease.
“We found that participants without memory impairments and who consumed more coffee had a lower risk of developing mild cognitive impairment – which often precedes Alzheimer’s disease – or of developing Alzheimer’s disease in the course of the study,” summarizes Dr. Gardener summarized the key results.
Better cognitive functions from coffee
Higher coffee consumption was associated with better cognitive functions in the participants, especially in the area of executive functions, which among other things have an impact on a person’s planning, self-control and attention.
Less amyloid deposits in the brain
The working group also found indications that higher coffee consumption slows down the accumulation of amyloid proteins in the brain. Amyloid deposits in the brain have been linked to the development of Alzheimer’s disease in numerous studies.
The results are encouraging, as drinking coffee could be a way to lower the risk of Alzheimer’s and “it’s a simple thing that people can change,” said Dr. Gardener.
Limitation of the study results
The head of the study points out, however, that further investigations are required to confirm the observations. In addition, the cohort examined was relatively small with around 200 people. Nevertheless, a clear connection between coffee consumption and Alzheimer’s risk could be observed.
Two cups of coffee are better than one
The study did not determine the optimal amount of coffee, but the results suggest that consuming two cups of coffee a day has a more pronounced effect than one cup a day.
The increase in coffee consumption from one cup (approx. 240 milliliters) to two was associated with an eight percent slower decline in cognitive decline after 18 months. In addition, after increasing the coffee quota, an average of five percent fewer amyloid deposits accumulated.
More extensive research needs to be done
“We need to investigate more closely whether coffee consumption can be recommended as a lifestyle factor in order to delay the onset of Alzheimer’s disease,” sums up Dr. Gardener. In addition, it has to be determined which components of the coffee are responsible for the apparently positive effects. In addition to caffeine, other ingredients in coffee can also be used, such as cafestol, kahweol and eicosanoyl-5-hydroxytryptamide.
Coffee and tea seem to reduce the risk of stroke
Another recent study by researchers at Tianjin Medical University in China has also shown that regular drinking of tea and / or coffee is associated with a reduced risk of stroke and dementia. For more information, read the article “Coffee and Tea Reduce the Risk of Stroke and Dementia”. (vb)
