Dementia is typically diagnosed in older adults, but the biological groundwork for the disease is often laid as early as conception. Physical changes in the brain can begin up to two decades before the first symptoms appear. This highlights a crucial truth: maintaining brain health isn't something to start in old age; it is a lifelong process. The best time to prevent dementia is years, even decades, before it manifests.
Nearly 40–50% of dementia cases are considered preventable through lifestyle modifications. Here is how you can protect your brain at every stage of life.

1. Early Life: The Foundation (Conception to Young Adulthood)
• Prenatal Care: While we cannot control our own experience in the womb, intending parents can protect their future children. A healthy lifestyle—avoiding alcohol and smoking, and managing conditions like hypertension and diabetes during pregnancy—builds a resilient foundation for a child's brain.
• Quality Education: Education strengthens the connections between brain cells. A well-developed "cognitive reserve" helps the brain resist the damage that leads to dementia. If you are a young person, prioritize learning and mental stimulation. Keep your brain in "school mode" through reading, puzzles, or learning a trade. A curious brain is a protected brain.
