Alzheimer’s Brains Can Surprise You

The aging brain is unpredictable. Some people are cognitively sharp and productive well into their nineties. Others become afflicted with Alzheimer’s and other dementias. Not many people realize that the brain can compensate for some of its decline. Consumer Reports On-Health asserts in its cover article for July that the brain has the potential to build up a “mental reserve.”

Dr. Paul Nussbaum from the University of Pittsburgh School of Medicine cites the example of autopsies of brains riddled with the distinctive Alzheimer’s plaques and tangles did not manifest any evidence of the disease in the patients when they were alive. This is possible, Nussbaum explains, because of cognitive reserve, extra brain structures and networks created during a lifetime of learning and growing.

I have read the same studies which he cites, specifically research which traced women who wrote complex essays during their college and graduate school years, yet when they aged, never evinced Alzheimer’s symptoms while their brains clearly showed signs that they had been damaged by the disease. Also, there was a well-known study of nuns’ brains which when autopsied, had significant signs of Alzheimer’s disease, yet never had any symptoms. These nuns were the creative and innovative ones in the convent – the ones who didn’t dot their i’s or cross their t’s.

Therefore it’s not too late if you are worried about getting Alzheimer’s because of the aging process, or due to a genetic link in your family:
