Boozing really does rot your brain: "Middle-aged adults who binge drink may face a heightened risk of dementia later in life, a study has suggested. Researchers found even among adults who usually drank moderately, those who occasionally binged were more likely than their peers to develop dementia over the next 25 years. Overall, middle-aged adults who binged at least once a month - downing, for instance, five bottles of beer or a bottle of wine in one sitting - had a three times greater risk of developing dementia, including Alzheimer's disease. The findings were published in the medical journal, Epidemiology. Study co-author Jaakko Kaprio of the University of Helsinki, Finland, said it was not surprising binge drinking was related to a higher dementia risk. But the risk had not been well documented before, he said".
