LOS ANGELES (KTLA) – Amid the devastating wildfires in Southern California, Bruce Willis took time to thank first responders in a rare public appearance since his dementia diagnosis. The actor's wife, Emma Heming Willis, posted a heartwarming video on Instagram on Thursday showing him shaking hands with members of the Los Angeles Police Department. "Spotting a first responder, Bruce never missed a chance to show his gratitude with a heartfelt handshake and a 'thank you for your service," she wrote in the post's caption.

In 2023, his family revealed he was diagnosed with frontotemporal dementia (FTD). According to Johns Hopkins Medicine, FTD is a common cause of dementia that occurs when nerve cells in the frontal and temporal lobes of the brain are lost, causing the lobes to shrink. Since his diagnosis, Willis's family has given regular updates on his condition. Favorable weather conditions this week have allowed firefighters to keep the Los Angeles-area blazes from growing, but they remain at tens of thousands of acres, with windy weather expected to return over the weekend.
