Why do some people have the biological signs and damage of Alzheimer's disease, but their memory and intellectual abilities do not decline? Scientists have discovered the answer to this question. According to researchers at the Netherlands Institute for Neuroscience , a rare and special type of immature cells in the brains of such people manage to survive and fight off the damage of the disease, so they do not show symptoms of Alzheimer's. The discovery, published in the journal Cell Stem Cell , raises hopes for the development of completely new treatments to slow the progression of dementia and preserve memory. Why does Alzheimer's disease affect people differently? This has always been a great myst...
