Even when someone can no longer talk, music can become an avenue for communication and engagement. It seems to access parts of the brain that remain unaffected by dementia. People with dementia can have a special ability to remember songs. Even if people with dementia can’t talk, they may be able to sing, whistle, clap or tap their feet. It can help them, and their carers, to feel life is worthwhile. Listening to music can also have strong effects on people's moods. It can lift the spirit and trigger feelings of nostalgia.
