Interestingly, the conclusions of related studies are not consistent: some have found that drinking coffee can slow cognitive decline, while others suggest that excessive consumption may shrink brain volume and increase dementia risk. This article reviews several representative cohort studies from around 2021, involving findings from Edith Cowan University in Australia, Tianjin Medical University, and the University of South Australia, attempting to clarify the complex associations between coffee intake and Alzheimer's disease and stroke, and to explore the relationship between the number of cups consumed daily and the safe upper limit of caffeine.
