Losing memory to Alzheimer’s is a big fear for many, but staying mentally active can change the outcome. Doctors found that "cognitive enrichment"—which just means simple habits like reading, playing games, or learning a language—helps protect the brain. By keeping your mind busy from a young age into old age, you build a "brain reserve." This lowers the risk of Alzheimer’s by 38% and can delay memory loss by five years, helping people enjoy healthier and more independent lives.
