Texas requires any facility marketing memory care to file an Alzheimer's/dementia Disclosure Statement with HHSC under 26 TAC Section 553.264, covering staffing, training and physical design -- standard assisted living carries no such requirement.
What physically differs
Memory care units typically add secured egress with door alarms, staff trained specifically in redirection and de-escalation, and a physical layout designed to reduce disorientation. Ask to see the disclosure statement by name -- it must describe exactly these elements.
On cost
There is no published memory-care cost median anywhere, in Texas or any other state. Get quotes in writing from each community rather than relying on an average.
