Alzheimer’s disease is the most common neurodegenerative disease and the leading cause of dementia worldwide. Unfortunately, there is no known cure. Because of this, it is a big topic of focus for researchers.
Several studies show that coffee drinkers have up to a 65% lower risk of getting Alzheimer’s disease. While coffee and caffeine are known to enhance short-term memory and cognition, new research also suggests that long-term use may protect against cognitive decline or dementia. This may be mediated by caffeine and/or other mechanisms like antioxidant capacity and increased insulin sensitivity.
Given the enormous economic and emotional toll threatened by the current epidemic of Alzheimer's disease and other dementias, it is critically important to validate potential prevention strategies such as coffee and caffeine.
