Cognitive impairment is one of the major health problems facing elderly people in the new millennium. This does not only refer to dementia, but also to lesser degrees of cognitive deficit that are associated with a decreased quality of life and, in many cases, progress to dementia. Some studies suggest that delaying the emergence of dementia for a few years would result in a considerable decrease in the human and economic burden related to the condition.
