Says, "I want to go home" (whether home or not)
When it happens
Why it happens
As language skills decline, it may become harder to express complicated feelings. When the person is upset, scared, or feeling insecure, "home" represents a place of security and happiness.
What you can do
Don't necessarily take it literally. "Home" is often more of a concept of warmth than the person's current home. Often people with dementia refer to a childhood or past home as if it's where they live now.
Don't necessarily take it as a condemnation of current living quarters. Someone in a nursing facility may not literally mean they want to leave with you, but rather that they're upset about something that can be fixed: a brusque aide, being cold, feeling hungry.
Soothe by inviting, "You really miss home. Tell me about home."
If you think the person is still verbal enough to want to revisit a particular home, you can try this -- but be prepared for the possibility that even a favorite former home will not be remembered
