1. Get RID of background noise! People with dementia have a lot of confusion and it is hard for them to concentrate and pay attention. If possible make sure the background noise is quiet when you want to communicate with them!
2. Give them 2 choices! Everyone likes a choice, including the loved one with Alzheimer's disease. The person still wants to feel like they have control. My mom used to let me pick vegetables (which I do not love). I had 2 choices "broccoli or string beans". I felt like I had POWER. Your loved one would like that power too!
3. Observe behavior. If your loved one always refuses to drink water, maybe they want something with a little flavor. Your family member is not able to put into words their feelings. We need to try to figure it out.
