I've been doing some hospice volunteering recently. One of my patients is a sweet lady in her eighties with dementia and other ailments. She will respond to my efforts at conversation with word salad, rarely speaking in complete sentences or making any sense. She will smile and laugh at my jokes so it seems there may be some level of comprehension, but I'm wondering how much is getting through and if the correct phrase or response is in her brain and she has just lost the ability to find the right words in response. I'd like to find some way to communicate with her but she may be too impaired. I don't know. Any thoughts out there?
