The Dementia Time Bomb

The Human Brain: dangerously susceptible to the effects of degenerative cognitive symptoms. Source: J E Theriot, Flickr There is no doubt that people are living longer lives, and even in recent years the global life expectancy has continued to increase; between 1990 and 2011 life expectancy for both sexes has climbed from 64 years to 70 years. This is a pattern seen across the world with the majority of nations seeing an increase in life expectancy. However, this spike in life expectancy has some less happy ramifications. The most acute of these is a spike in diseases associated with old age particularly in neurodegenerative diseases like dementia.
