Alzheimer’s Genes Work Like a Countdown Clock

Wild new study says certain gene mutations can actually predict when Alzheimer’s will hit—almost down to the year. Scientists found that changes in three specific genes (PSEN1, PSEN2, APP) tweak the brain’s chemistry, basically setting a timer for when symptoms start. Some mutations speed things up, others delay it, and even tiny shifts can mean years gained or lost. This could totally change how doctors spot and treat early-onset Alzheimer’s! #Alzheimers #Genetics #ScienceNews #BrainHealth #Health
