Lester Holt, Anchor, NBC Nightly News: There is promising news tonight in the fight against dementia. While it's been expected to skyrocket in the coming years as America ages, there are signs the trend could be stopped, especially with the second most common kind of dementia after Alzheimer's. And as NBC's Joe Fryer reports, doctors say the reason has as much to do with the heart as it does with the brain.
Joe Fryer, Reporter, NBC News: For Cynthia Huling Hummel, dementia is a family battle. Five years ago, she was diagnosed with mild cognitive impairment, and nearly two years ago, her mother Claire died from Alzheimer's.
Cynthia Huling Hummel: She loved music and she loved the arts and she loved to read and she lost that all, little by little.
JF: Following her own diagnosis, Cynthia made major lifestyle changes, becoming more physically active, and engaging her brain by taking college classes.
CHH: I'm trying to push off this disease, to run as fast as I can from it.
JF: The benefits of such healthy steps are reflected in a study published in The New England Journal of Medicine (NEJM). It finds the kind of dementia caused by vascular problems appears to be on the decline, down on average 29% per decade since 1977. The trend's especially strong for those with at least a high school diploma. The study says better treatment of stroke and heart disease might be a reason.
Dr. Keith Fargo, Director of Scientific Programs and Outreach, Alzheimer's Association: What it does do is give us further evidence that controlling your heart-health risk factors can reduce your likelihood of developing dementia as you age.
JF: Vascular dementia accounts for 10% of all dementia cases, but experts say everyone can benefit from this research. Numerous studies find you can reduce your risk of dementia by exercising regularly, anything that raises your heart rate, pumping more blood to the brain. It's worked for Cynthia. Her memory has not declined.
CHH: It's a fight for my memory. It's a fight for my family. It's a fight for others who are diagnosed. And so, I'm in it to win it!
JF: She knows the battle for her brain is fought with her entire body. Joe Fryer, NBC News.
