This heart-warming footage shows how a dad struck down with devastating Alzheimer’s comes “back to life” when he hears his favourite songs. Eddie O’Brien, 74, was diagnosed with the crushing illness three years ago after his family noticed he was forgetting names and getting lost on his way home. The debilitating condition can leave him struggling to verbally communicate with his family. But when his daughter Rebecca, 30, began playing his old tunes and bought him some headphones, she watched as his mood transformed before her eyes. As soon as he hears music, his feet start tapping and he is up dancing. Although the retired decorator is especially fond of Elvis, Rebecca says Eddie is quite happy to bust out his “crazy moves” to any music – from rap to country and western. And she said its fantastic to see her dad “loving life” despite his disease - and become “so happy” when listening to a thumping beat. Rebecca, of Warrington, Cheshire, said: “It’s just a breath of fresh air to be honest, because it can be so heart-breaking. “A lot of the time, it makes people become angrier and more agitated and frustrated because they don’t know what’s going on. “But with my Dad, he just doesn’t seem to care, and I think that’s the best way to be - he’s absolutely loving life now. “And he just has these crazy moves - you can just tell he’s just so happy, and it just really brings him back to life.”
