Memory Care Costs in O'Fallon: What Metro East Families Should Know
When a parent is living with Alzheimer's disease or another dementia, there often comes a time when home, or even standard assisted living, no longer feels safe. Memory care is designed for that stage, with more supervision, structured routines, and a secure environment. It is also one of the hardest costs to research, because most published surveys do not report memory care on its own. This guide explains what the data shows for O'Fallon and the St. Louis area, how Illinois regulates dementia care programs, and how families can compare options.
Why there is no single local figure
The CareScout Cost of Care Survey reports assisted living costs by metro area but does not publish a separate memory care figure. For the St. Louis metro area, which includes O'Fallon, CareScout's 2025 survey reports a median of $6,050 a month for assisted living (CareScout Cost of Care tool). Memory care is generally priced above that, because it involves more staff time and supervision.
For a national reference, the National Investment Center for Seniors Housing and Care (NIC) reported that in the third quarter of 2025, average asking rents in rental continuing care retirement communities were $6,459 a month for assisted living and $8,238 for memory care, about 28 percent higher (NIC, CCRC performance 3Q 2025). That national figure from one type of community shows the general gap between the two levels of care. It is not an O'Fallon price. The reliable way to know local memory care costs is to ask each program for a written quote.
How Illinois regulates dementia care programs
Illinois' Alzheimer's Disease and Related Dementias Special Care Disclosure Act applies to any facility that offers care for people with Alzheimer's disease and related dementias through a special care unit or center. Such a facility must disclose in writing, both to the state agency that licenses it and to potential clients or their representatives (210 ILCS 4/15):
- The form of care or treatment that makes it suitable for people with dementia
- Its philosophy of dementia care
- Pre-admission, admission, and discharge procedures
- Assessment, care planning, and implementation guidelines
- Minimum and maximum staffing ratios
- The physical environment
- Activities available to clients
- The role of family members in care
- The costs of care and treatment under the program
This written disclosure is one of the best tools a family has. Ask every memory care program for it, and compare them side by side, especially the staffing ratios and the costs.
Illinois' Assisted Living and Shared Housing Act also matters. It sets residency limits for assisted living and shared housing, such as not accepting a person who requires total assistance with two or more activities of daily living, and it specifically notes that its exclusion for severe mental illness does not include Alzheimer's disease and other dementias (210 ILCS 9/75).
What shapes the price of memory care
Staffing and supervision
People living with dementia often need frequent check-ins, step-by-step help with daily tasks, and someone available at night. More staff time means a higher price.
Programming
Memory care programs usually include structured routines and activities adapted to cognitive needs, such as music, reminiscence, simple tasks, and time outdoors in a secure space.
Environment
Secure exits, easy-to-follow layouts, calm lighting, and familiar, homelike spaces all affect cost. Smaller residential settings can feel less overwhelming for some people with dementia.
Pricing structure
Some programs charge one inclusive rate. Others charge a base rate plus care levels. The Illinois disclosure must describe costs, so ask for it in writing.
Comparing memory care with other options
CareScout's 2025 survey reports these St. Louis-area medians:
| Type of care (St. Louis area, 2025) | Median cost |
|---|---|
| Home health aide, 44 hours a week | $6,673 a month |
| Assisted living | $6,050 a month |
| Nursing home, semi-private room | $8,060 a month |
| Nursing home, private room | $9,247 a month |
Dementia care at home often requires far more than 44 hours a week of help, especially when someone is awake at night or at risk of wandering. Nursing homes provide round-the-clock nursing care, which some people with advanced dementia need. Many people living with dementia do not need that level of medical care, but do benefit from the supervision and structure of memory care. Our guide to assisted living vs. nursing home costs in O'Fallon compares those settings.
How families pay for memory care
Most families pay privately, using income, savings, home equity, and long-term care insurance. Other options include:
VA Aid and Attendance. Wartime veterans and surviving spouses who meet income, asset, and care-need requirements may receive an enhanced pension. From December 1, 2025, through November 30, 2026, the maximum annual pension with Aid and Attendance is $29,093 for a veteran with no dependents and $34,488 for a veteran with one dependent, with a net worth limit of $163,699 (VA, Veterans Pension rates). This is relevant for many families near Scott Air Force Base.
Illinois Supportive Living Program. At certified sites, Medicaid covers services while residents pay room and board; certified Dementia Care Settings are part of the program. Our guide to paying for assisted living in O'Fallon explains it.
Adult day and respite. For families still caring for a parent at home, adult day services and short respite stays can bridge the gap. See our guide to adult day care in O'Fallon.
