MADISON, Wis. -

The state's new Silver Alert System is online as of Aug. 1. About 60 percent of people with dementia will at some point wander off, according to the Alzheimer's & Dementia Alliance of Wisconsin. The organization said they pushed to get this bill enacted before winter.

Rob Gunderman is the public policy director for Alzheimer's & Dementia Alliance of Wisconsin.

"If you don't find a person who wanders when they have dementia within 24 hours, statistically, the probability is that you won't have a positive outcome. You aren't going to find them alive," said Gunderman.

Gunderman said the key to finding people when they are missing is having many people looking for them. The new Silver Alert system is modeled after the Amber Alert system for missing kids. Silver alerts will be provided to radio and television broadcasters for free. That increases the likelihood of finding the missing senior exponentially.
