Tuesday, August 07, 2007"Caffeine is a psychostimulant which appears to reduce cognitive decline in women." Using tests of memory and thinking skills, Ritchie and colleagues showed that cognitive decline was slower in women aged 65 and over who drank more than three cups of caffeinated coffee or tea a day compared with women who drank one cup or less. The results were unaffected by potential confounding factors such as age, education, disability, depression, medication, hypertension (high blood pressure), cardiovascular disease and other chronic conditions. However, until more is discovered about how and why this is so, the authors are not suggesting older women should start drinking more coffee.... Awww, how come? Maybe because of this: Caffeine consumption did not reduce dementia risk over 4 years. The abstract only describes the findings in terms of risks rather than absolute numbers, so it's impossible evaluate how truly significant the differences between the coffee drinkers and non-drinkers were, but that last sentence in the results section pretty much says it all. Drinking coffee doesn't preserve the mind. posted by Sydney on 8/07/2007 07:59:00 AM 0 comments 0 Comments: |
