Coffee debate update
So the coffee debate continues. Today’s headline in The Telegraph shouts an enthusiastic message that drinking coffee could reverse the signs of Alzhiemer’s disease. The trial led by Dr Gary Arendash, an American neuroscientist presents evidence that indicates that caffeine not only helps to stave off the disease, but can actually treat it. The defining hallmark of Alzheimer’s disease is the accumulation of β-amyloid protein plaques in the the areas of the brain responsible for memory (the cortex and hippocampus). These ‘sticky’ deposits are known to damage nerve cells, interfere with nerve signalling and therefore memory. Caffeine, it appears, actually reduces the production of β-amyloid protein and therefore would reduce the production of plaques. So that’s the good news folks. The bad news is that this groundbreaking research was conducted using mice. Not bad news as such if you’re a coffee drinking mouse who can’t remember where you’ve left your cheese. These findings do however support an earlier study published in January this year. Led by Marjo H. Eskelinen the study found that among 1,400 Finnish adults followed for 20 years, those who drank three to five cups of coffee per day in middle-age were two-thirds less likely than non-drinkers to develop dementia, including Alzheimer’s disease. So for the time being I shall continue to enjoy my morning cafetière, not only because I enjoy the ritual and the taste but because it may, just may help me retain my memory in years to come.
