Three Women, Three Legacies: How They Shaped the Way We Understand Dementia

Written by Team Vallige

In honor of Women’s History Month

Women’s History Month is a time to celebrate trailblazers, barriers broken, and lives that changed the world.

But some of the most meaningful history isn’t only written in awards, headlines, or textbooks. Sometimes, it’s written in hospital rooms, family living rooms, research labs, and quiet moments of care. Dementia and Alzheimer’s have been shaped not only by science—but by stories, courage, and the people who made the invisible visible.

This month, we’re honoring three very different women—a scientist, a celebrity, and a civil rights icon—whose lives helped move dementia out of the shadows and into greater understanding, research, and compassion.

Their paths were different. Their impact is deeply connected.

Dr. Rita Levi-Montalcini: The Scientist Who Taught the Brain How to Survive

Rita Levi-Montalcini’s life reads like something out of a novel. Barred from working in universities in Italy during World War II because she was Jewish, she refused to stop doing science. Instead, she built a tiny laboratory in her bedroom and kept experimenting anyway.

That determination led her to one of the most important discoveries in neuroscience: nerve growth factor (NGF)—a molecule that helps brain cells grow, survive, and stay healthy. Her work later earned her a Nobel Prize and helped lay the foundation for modern brain science.

Alzheimer’s and other dementias involve the gradual damage and loss of brain cells. Levi-Montalcini’s discovery helped scientists understand how neurons stay alive, what happens when their support systems break down, and why protecting and supporting brain cells is such a major focus of research and treatment.

Today, when you hear about therapies aimed at slowing progression, supporting brain health, or protecting neurons, you’re seeing the ripple effects of her work. It’s a reminder that there is real biology behind what’s happening in dementia—and real science working to protect what can be protected.

Rita Hayworth: The Star Who Changed Public Awareness

In the 1940s and 50s, Rita Hayworth was one of the most famous actresses in the world—glamorous, magnetic, unforgettable. But later in life, her behavior began to change. She became forgetful, disoriented, and emotionally unpredictable.

For years, people assumed it was stress, burnout, or alcoholism.

It wasn’t.

Rita Hayworth was living with Alzheimer’s disease—at a time when most people barely understood what that meant. When her diagnosis became public, her daughter, Princess Yasmin Aga Khan, became a powerful advocate for Alzheimer’s awareness and research.

Before stories like Hayworth’s were widely known, many people believed memory loss was just “normal aging,” or that confusion and personality changes were personal or behavioral failings. Her story helped shift public understanding toward the truth: Alzheimer’s is a disease of the brain, not a failure of character, effort, or love.

That shift still matters today—especially for families who find themselves explaining, again and again, that what they’re seeing isn’t something their loved one can simply control.

Rosa Parks: Dignity, Even When Memory Fades

Most of us know Rosa Parks as the woman who refused to give up her seat and helped change the course of history. What’s less widely known is that in her later years, she lived with dementia.

As her memory and independence declined, she needed care, protection, and support—just like millions of people and families today. Even in this chapter of her life, her story sparked important conversations about elder care, legal protections, and dignity for people living with cognitive decline.

Her life is a powerful reminder that dementia does not erase a person’s worth or legacy. The need for care does not diminish who someone is. Dignity isn’t something you lose when abilities change—it’s something that deserves to be protected even more fiercely.

The Thread That Connects Them All

These three women changed the dementia story in different ways—through science, visibility, and lived experience. Together, they show us something essential: dementia is not just a medical condition. It’s a human journey—one that touches memory, identity, relationships, and care.

And that journey isn’t only shaped by researchers or public figures. It’s shaped every day by families and caregivers in ordinary, extraordinary acts of patience, love, and persistence.

At Vallige, we believe care works best when the whole village is supported—when families have simple tools to stay connected, notice changes early, share the emotional load, and protect both the person living with dementia and the people who love them. Whether it’s capturing moments, tracking wellbeing, or helping caregivers feel less alone, our goal is to make this journey a little more supported, a little more human, and a little less heavy.

If you’re caring for someone with dementia—or you’re part of the village supporting them—we’d love to walk alongside you.

Because progress doesn’t just come from history-makers.

It comes from everyday care, shared moments, and people showing up—just like you.
