The Brain Injury Alliance of Kentucky hosted its annual Walk and Roll for Brain Health Saturday morning.WLKY's Jennifer Baileys was the emcee for the event, which was hosted at E. P. Tom Sawyer Park.The mission of the event was to provide resources and support, while advocating for Kentuckians affected by brain injuries."I've seen a lot of people today, or several anyway, that last year when they were at the event, they were in a wheelchair to be rolled through the event. Today they were actually walking the event, so that's very inspiring," said the executive director of BIAK, Bobby Paisley.The first 200 children at the event received a free helmet as part of BIAK’s ongoing injury prevention efforts.
