It seems that caffeine may finish up as a treatment for people with memory problems and/or dementia issues. Something that people obviously realised a long time ago, since coffee has always been a high valued luxury food.
The article states that caffeine improved memory in mice which have been bred to be prone to Alzheimer's, and that it reduced amyloids in the brain and blood by almost one half in both human patients and the mice.
What seems strange to me is that a percentage of people already do drink the required number of cups of coffee (five, if you're wondering, is the dose mentioned in the article) and a percentage of people get Alzheimer's. Maybe there's already survey/research results out there that can be used to support or disprove the efficacy of caffeine?
Me, I can't wait until coffee is covered by a PBS subsidy... %)
