A new study conducted by Scandinavian researchers suggests that drinking coffee may dramatically decrease Alzheimer's disease and other forms of dementia. The Cardiovascular Risk Factors, Aging and Dementia (CAIDE) study, begun in 1972, has recently found that individuals who drank between three to five cups of coffee each day when they were middle aged were 65% less likely to develop dementia and Alzheimer's in later life. Over 26 million people worldwide are afflicted with Alzheimer's, and that figure could grow four-fold in the next forty years, leaving 1 out of every 85 people on the planet affected. The direct and indirect care costs for Alzheimer's, the most common form of dementia, is currently well over $100 billion dollars in the US alone.
"We aimed to study the association between coffee and tea consumption at midlife and dementia/AD risk in late-life, because the long-term impact of caffeine on the central nervous system was still unknown, and as the pathologic processes leading to Alzheimer's disease may start decades before the clinical manifestation of the disease," said lead researcher, Miia Kivipelto.
While drinking coffee produced a dramatically lessened risk, tea consumption has not yet shown a significant effect on dementia risks. Previous studies have noted that coffee consumption may help reduce dementia, as in the case of Parkinson's disease.
“[These findings need] to be confirmed by other studies, but it opens the possibility that dietary interventions could modify the risk of dementia/Alzheimer's Disease. Also, identification of mechanisms of how coffee exerts its protection against dementia/AD might help in the development of new therapies for these diseases," said Kivipelto.
