Golden Carers is just wonderful. An amazing resource shared all over the world. I use Golden carers on a daily basis and added with Pinterest, it just makes my job that little bit easier on those days when inspiration doesn't come easy. I love that there is always something new every time I look.
Use the words, "Let's" So instead of asking a "Yes" or "No" question, use the words "Let's"
"Let's get cleaned up" instead of "Do you want to get a shower"
"Let's go check out..." instead of "Do you want to try this activity"
"Let's go for a walk!"
Anytime a person with cognitive impairment is asked a "Yes" or "No" question, the answer is always NO and there will be some hesitation.
Check out Teepa Snow on youtube. She is a great instructor for Dementia Care.
If your patient previously enjoyed music, you could engage him in looking at record sleeves - talking about the performer. If he was a nature lover, suggest a walk, saying "would you like to see if we can find a squirrel or would you rather look for a rose" for example. No options for no there - it will make him think a little and may spark a memory.
Good luck and bless you for caring so much.
