When a parent receives a dementia diagnosis, the shadow it casts over a child's future can feel like prophecy — but neuroscience suggests it is closer to a warning than a sentence. Researchers and clinicians increasingly agree that while family history shapes susceptibility, the daily architecture of a life — how one sleeps, moves, eats, listens, and connects — does much of the actual deciding. The brain, it turns out, is less a fixed inheritance than a living record of choices, and the record is still being written.
