Very good advice
1. Diminish distractions.
2. Converse one-on-one.
3. Keep things simple.
4. Avoid arguments (this should be number 1).
5. Just keep talking.
I would also like to add:
6. Walk in their shoes.
7. Step into their world and speak their “language” (even if it makes no sense………………… my mom was only able to articulate herself using the words, “despierta America” and “la fruta”).
8. Take a deep breath if you get frustrated (because you probably will).
9. Talk to other family and friends about how to best communicate with your loved one. They might keep visiting if they feel like they’re actually helping or supporting the person with dementia.
