Your brain is your career, your relationships, your independence. When brain health declines — brain fog, memory lapses, mental fatigue — everything collapses with it. You underperform at work. You're irritable at home. You feel like you're losing yourself. For millions, these early signs quietly progress toward Alzheimer's, Parkinson's, and other neurodegenerative diseases. The science is clear: early detection and intervention can dramatically reduce that risk. But today, the only tools that exist — MRIs, neurologists, clinical assessments — are designed for diagnosis, not prevention. They're expensive, inaccessible, and by the time you get there, it's often too late to change course.
