Study: Rare genetic mutation appears to have protected second person from early Alzheimer’s
For the second time in one extended family, researchers have identified a person who seemed genetically destined to develop early Alzheimer’s, but remained cognitively sound for several more decades.
For the second time in one extended family, researchers have identified a person who seemed genetically destined to develop early Alzheimer’s, but remained cognitively sound for several more decades.
Like with the first case, the scientists zeroed in on another genetic variant that seemed to be protective, overcoming the impact of the mutation that would have otherwise set this man on the course for dementia in his 40s. Notably, it was in a different gene than in the first case, signaling there are multiple pathways that appear to stave off cognitive decline.
