It's amazing what stays in there. I remember a lady with advanced dementia we looked after and in 5 years, she never said a word. She barked, growled and bit- but never actually said anything. One day I was talking to someone by the door of the lounge and she just called out my name. Everyone was amazed that not only had she known it and got the right person, but she had recognised me just from my voice. You never can tell...
