What memory care includes in Missouri
Memory care is a secured, structured setting with dementia-trained staff for residents who wander, need extra cueing, or are no longer safe in standard assisted living.
Missouri has no separate memory-care license; dementia care is delivered within an Assisted Living Facility (occasionally an RCF II) under Chapter 198 RSMo and 19 CSR 30-86's Alzheimer's Special Care Disclosure rules, which require disclosure of the specific dementia-care services offered. A typical monthly range is $4,400 to $6,400 a month.
Before you tour, know what actually predicts quality:
- that the specific secured unit is disclosed and staffed as a dementia-care setting
- how many dementia-training hours staff have completed, and how recently
- the awake-overnight ratio in the secured unit specifically
