Nicole Petrie knows the power of familiar tunes for people living with dementia.<br /><br />This deeply personal and powerful clip shows Nicole's mom, Cheryl in a moment of anxiety. When Nicole plays Fleetwood Mac's song "Rhiannon," her mom becomes visibly uplifted, laughing and clicking her fingers.<br /><br />Nicole told Newsflare: "My mother has Frontotemporal Dementia (FTD), and when she is having a bad day or moment of confusion, music can almost instantly improve her mood.<br /><br />"She started showing signs around 2012 when she was 48. It took a couple years after that to get the official diagnosis because the doctors didn’t consider dementia at first because she was so young still.<br /><br />"My dad thinks there might have been signs of something wrong as early as 2010, but it's hard to be sure because it was very unexpected around that age."<br /><br />Model and activist, Nicole, aged 25, documents the close bond she shares with her mom on TikTok (@nicolepetrie).
