Carey Mulligan on dementia and music

As part of her guest editorship of Today, Carey Mulligan explores the stigma associated with dementia and asks if more can be done to widen understanding of the disease.

She is joined by Michael Parkinson, whose mother suffered from dementia, and Michael Palin, whose good friend and comedian-in-arms Terry Jones has frontotemporal dementia. They all say music is something their loved ones still react to.
