A team of scientists has discovered the second case of a person resistant to Alzheimer's. They confirmed that he had genes that delayed the disease.

They say it opens the door for the development of new therapies. Both people studied were "condemned" by nature with a gene that causes Alzheimer's and, at the same time, "endowed" with another gene that protected them from the symptoms of the disease for more than two decades. The solution would be to "imitate nature by developing therapies that mimic the protective mechanism of these genetic variants"
