First, earlier studies have linked coffee consumption with a decreased risk of type 2 diabetes, which in turn has been associated with a greater risk of dementia. In animal studies, caffeine has been shown to reduce the formation of amyloid plaques in the brain, one of the hallmarks of Alzheimer’s disease. Finally, coffee may have an antioxidant effect in the bloodstream, reducing vascular risk factors for dementia.
Dr. Kivipelto noted that previous studies have shown that coffee drinking may also be linked to a reduced risk of Parkinson’s disease.
