“A member of the world’s largest family to suffer from Alzheimer’s, she, like generations of her relatives, was born with a gene mutation that causes people to begin having memory and thinking problems in their 40s and deteriorate rapidly toward death around age 60. But remarkably, she experienced no cognitive decline at all until her 70s, nearly three decades later than expected.” Can one woman’s ultra rare genetic mutation set researchers off on a new (and hopefully, more fruitful) path towards finding a way to slow or even prevent Alzheimers? From the NYT: Why Didn’t She Get Alzheimer’s? The Answer Could Hold a Key to Fighting the Disease.
