Aliria Rosa Piedrahita de Villegas carried a rare genetic mutation that had all but guaranteed she would develop Alzheimer’s disease in her 40s. But only at age 72 did she experience the first symptoms of it.
Now researchers are studying Aliria’s donated brain to try and unlock the genetic secrets that may have delayed the disease’s onset.
