Why don’t we all get Alzheimer’s?

Conventional wisdom has it that people who develop Alzheimer’s disease have certain characteristics in their brains that causes cognitive deterioration. But, according to researchers at the University of California, San Diego, we all have the building blocks of the disease in our brains. It just takes a chain of events to occur within the brain to trigger the condition.

The researchers found that when a specific protein and enzyme combine, progressive cell generation and death occurs--common characteristics of Alzheimer’s.  The process was described as being like keeping gunpowder and a match separate--when combined, there’s an explosion.

The researchers hope the discovery of this key to the development of Alzheimer’s can provide more insight into how the disease progresses and how it can be treated and, hopefully prevented. Currently, more than 5 million Americans have Alzheimer’s and that number is expected to triple by 2050.
