A new analysis of a standard brain test may help predict dementia
...er analysis of the EEG, which measures the brain's electrical
activity, accurately predicted healthy people in their 60s and 70s who would develop dementia over the next 7 to 10 years. It also identified individuals who would remain virtually unchanged over the same time span. The EEGs were almost 95 percent ac...
New insights into cost-effectiveness of implanted heart device
