Drinking coffee has been tipped as a possible way of delaying and even preventing Alzheimer's disease in previous research. However these studies have only ever involved a small number of people and were reliant on participants remembering how much tea and coffee they drank earlier in their lives.
This latest study showed that cognitive decline was significantly less among people who drank three cups of coffee every day. These findings add weight to the body of existing evidence suggesting long-term caffeine intake may have a protective effect against the onset of Alzheimer's disease.
It is too soon to say our morning coffee or afternoon cup of tea is anything more than a pleasant pick-me-up. It is important to now research further how caffeine consumption impacts on dementia risk.
