alzheimer s and coffee

Summary

Regular and moderate coffee consumption may be associated with a lower risk of developing Alzheimer's and delaying its onset, potentially due to the caffeine, antioxidants, and other compounds in coffee that can benefit memory, mood, and cognitive function. 1 2 3 However, heavy coffee consumption may increase the risk of dementia. 2 Caffeine and dementia have been studied many times, with some finding that people who do not develop dementia have twice as much caffeine in their blood as those who do. 3 Research has suggested that caffeine can counter dementia by blocking the cells' ability to recognize adenosine, and that decaffeinated coffee increases production of granulocyte-colony stimulating factor. 3

Summary Caffeine and dementia have been studied many times, with some finding that people who do not develop dementia have twice as much caffeine in their blood as those who do. Research has suggested that caffeine can counter dementia by blocking the cells' ability to recognize adenosine, and that decaffeinated coffee increases production of granulocyte-colony stimulating factor. However, this effect is not seen with caffeine alone or decaffeinated coffee, suggesting that there could be a combination effect between caffeine and an unknown compound in coffee.
