Families with rare gene mutations that cause Alzheimer's in middle age are giving scientists a unique window on the disease, and a quick way to test potential treatments.

Engaging in diverse hobbies like socializing, exercising and reading may boost midlife brain health. Managing conditions like depression, diabetes and high blood pressure supports long-term brain function. Building cognitive reserve through stimulating activities may help reduce Alzheimer’s risk later in life.
