Women Make Up 2/3 of Alzheimer's Cases—and Half Are Preventable
New research confirms Maria Shriver's decades-old hunch: women represent two-thirds of Alzheimer's diagnoses, but scientists now say nearly half of all cases can be prevented. After her father's diagnosis, Shriver founded the Women's Alzheimer's Movement and is empowering people to take charge of their brain health early.
When Maria Shriver's father couldn't recognize a fork or his own daughter, she started asking questions that doctors said didn't matter. Decades later, those questions changed what we know about Alzheimer's disease.
Shriver's father, Sargent Shriver, created the Peace Corps and Job Corps before Alzheimer's took his memory in 2003. Watching a brilliant mind fade, Maria noticed something curious: the disease seemed to hit women harder than men.
Doctors told her she was wrong. She kept asking anyway.
Fast forward to today, and the numbers prove her right. Two-thirds of people diagnosed with Alzheimer's are women, confirmed by her work with the Women's Alzheimer's Movement at Cleveland Clinic.
A recent study analyzing over 17,000 adults found that heart and metabolic health problems hit women's brain function harder than men's. Scientists still can't fully explain why women face higher risk, but knowing this fact alone represents huge progress.
Here's the really good news: nearly half of all Alzheimer's cases are preventable. Research from the Alzheimer's Association shows that exercise, brain games, nutrition, and whole-body health monitoring significantly protect your brain.
The medical journal The Lancet lists 14 modifiable risk factors that together could reduce dementia risk by 45 percent. "That's an empowering place to be, as opposed to a powerless place," Shriver says.
The shift is already happening in how we approach brain health. Experts now recommend discussing brain health during annual checkups starting at age 55, though it's never too early to start.
Simple changes make a real difference. A daily 30-minute walk, weekly lunch dates with friends, getting seven to eight hours of sleep, and learning new things all strengthen your brain.
Why This Inspires
Seven million Americans live with Alzheimer's, yet the conversation is just beginning. By speaking up about brain health with friends, family, and doctors, we're breaking down stigma and opening doors to early intervention.
At 70, Shriver lifts weights four times weekly and protects her sleep schedule fiercely. She's living proof that taking charge of brain health isn't about fear—it's about hope and action.
What doctors once dismissed as impossible is now within reach: real, measurable ways to protect the organ that makes us who we are.
