More than 5-million Americans are living with Alzheimer's.
And, with an aging baby boomer population, it's becoming more and more of an issue.
That's why people came together Saturday morning at Elmwood Park in Roanoke.
The Alzheimer's Association's Walk to End Alzheimer's took hundreds of people on a two-mile loop around the city.
Alzheimer's is a type of dementia that causes problems with memory, thinking and behavior
The group hopes to raise awareness and put an end to the disease.
"I think people come back because the work isn't done. The fight is still very much a big fight. There are more and more individuals being impacted by Alzheimer's until we get real treatments, a cure and prevention, we need everyone to come and join us," explains Sue Friedman, President of the Central and Western VA chapter of the Alzheimer's Association.
Friedman say this walk has been taking place for more than 20-years.
A similar Alzheimer's walk also took place in Blacksburg.
