If you have an interest in learning about dementia and Alzheimer's, and are not familiar with Teepa Snow, I recommend her highly. Below are a few of her videos that I selected randomly but if you search on her name on YouTube, you'll find many more. Or you can visit her website at teepasnow.com.
In the past 20 years I have had the pleasant opportunity to attend at least 7 of Teepa's seminars on Alzheimer's and Dementia. Once we sat quietly and had coffee, meanwhile chatting about a specific topic related to her expertise, that was on the intermission of the class though. A very kind informative woman with loads of insight and forthcoming. Once I participated in a 'skit' on stage and in front of the attending audience. That was enlightening and interesting. I also highly recommend her, she has an abundance of things to teach, share and educate on.
