Yet, there is no successful alternative but to accept whatever the dementia person claims as their reality - no matter how untrue it is to us. AND ONLY IF we accept this dementia world on the terms of the person with dementia. If you are not their spouse, you are not. It is Sunday. You are 85.
Emotions are also very different in the dementia universe.
First, consider that the dementia person's reasoning abilities are very limited or perhaps gone completely. There are actual changes in the brain that affect a dementia person's ability to think. So, they are somewhat like a pre-schooler in their ability to assess, judge, make decisions, etc. Most dementia folks have some difficulty in understanding the spoken language. It is very true that in the dementia universe, it is NOT so much what you say, but HOW you say it.
