- More than 7 million Americans live with Alzheimer's today, and researchers project that number will rise to 13 million by 2050, doubling the burden on families
- Researchers at the Jackson Laboratory (JAX) discovered twisted, narrowed retinal vessels in mice carrying a common gene mutation, showing changes that resemble early Alzheimer's signs years before memory decline begins
- They also found disrupted protein activity in both brain and retina, weakening energy production and vessel support, creating the conditions for Alzheimer's long before symptoms appear
- Visual sensitivity testing in over 8,000 adults predicted dementia risk up to 12 years ahead, showing how everyday vision struggles may signal hidden brain changes
- Regular eye exams, better sleep, balanced carbohydrates, healthy fats, sunlight exposure, and methylene blue support offer practical steps to strengthen vessel health and protect your brain
