This was a very moving episode which revealed "how personalised playlists can re-awaken the brains of people with dementia".
A woman with dementia was able to conduct a perfectly intelligible and intelligent conversation after listening to her favourite music. A man with Parkinsons Disease who shuffled and stumbled uncontrollably when he walked was able to dance faultlessly with a partner while listening to the music.
Truly amazing.
