"When he was just 30 years old, Daniel received a diagnosis... a rare form of Alzheimer's disease..."

"... a condition most common in over-65s, but which can affect much younger people too. 'Certain things happen every day, me forgetting what I've done, and also what I have to do,' Daniel says. 'It gets a bit overwhelming. Generally it's quite hard to be in social environments.' It was only when Daniel was diagnosed that he realised his father, who died at the age of 36, must have had the same condition. The news came just after the first birthdays of his own children, twins Lola and Jasper... There's a 50:50 chance, doctors say, that the faulty gene Daniel inherited will have been passed on to them too.... 'For someone of Dan's age, their lifespan is about four years from diagnosis. It's pretty scary to hear that, you just feel hopeless,' says his partner Jordan.... Daniel has joined a choir of people with dementia... The 18-strong choir is made up of people living in and around Nottingham, where McClure grew up, all of whom are living with dementia in one form or another."
