Individuals who drink three to five cups of coffee in middle age have lower risks for dementia and Alzheimer's later in life than those who drink more, or steer clear of the brew altogether. That's a conclusion made in a study appearing in the January issue of the Journal of Alzheimer's Disease.

"Given the large amount of coffee consumption globally, the results might have important implications for the prevention of or delaying the onset of dementia/AD,” said lead researcher Miia Kivipelto an associate professor at the University of Kuopio in Finland and Karolinska Institute in Sweden. “The finding needs to be confirmed by other studies, but it opens the possibility that dietary interventions could modify the risk of dementia/AD. Also, identification of mechanisms of how coffee exerts its protection against dementia/AD might help in the development of new therapies for these diseases."

Tea drinking among the 1,400 study subjects was not common, or associated with Alzheimer's or other forms of dementia, according to an adjunct finding of the Finnish Cardiovascular Risk Factors, Aging and Dementia Study.
