@dailymailuk: Gary was diagnosed with dementia at just 51, and he and his wife Natasha have been using social media for around five years to raise awareness of what it's like to live with young-onset dementia ❤️ One of their latest videos has gone viral, showing Gary unexpectedly remembering the words to his favourite song during a Take That concert. The touching moment has resonated with thousands online, highlighting the powerful connection between music and memory. Gary's videos with his family and carer not only raise awareness of dementia in young people, but also have warmed the hearts of the internet with his cheeky smile and funny personality. @dementiadiaries51
