According to the CDC, stroke costs the United States about $34 billion a year, including the cost of healthcare services, medicines to treat stroke, and missed work days. Annually, more than 795,000 people in the United States have a stroke.
The CDC also says that stroke is a leading cause of serious long-term disability, and that stroke reduces mobility in more than half of stroke survivors age 65 and over.

The FAST Act will be implemented in 2021.
