With mental disability that sometimes comes with age in the form of dementia, you are confronted with a condition that progresses. Because of this you can be certain that the level of care you need is going to change as the condition gets worse.
It was difficult enough getting my mother to leave her home to go to the assisted living home the first time. I knew she would eventually need more care in the form of an assisted living nursing home and I didn't want to have to go through the stress of another move.
Fortunately, I was able to find a facility that offered different levels of care. They have different wings so that residents can be housed with other residents with the same challenges.
When my mother got to the point she needed more care, she simply changed rooms and she hardly notice since she was still around the same caregivers.
