What's the difference between assisted living and memory care in Illinois?

Memory care is a specialized form of assisted living for residents living with Alzheimer's or dementia, and adds 24/7 secured environments, dementia-trained staff, and structured routines designed to reduce confusion and wandering.

What's the difference between assisted living and a nursing home in Illinois?

Nursing homes (skilled nursing facilities) provide 24/7 medical care from licensed nurses for residents with significant health needs, and are regulated more strictly under both state and federal CMS rules.

Does Illinois Medicaid cover assisted living?

Illinois Medicaid does not directly pay room-and-board for assisted living, but most states (including Illinois) offer Home and Community-Based Services (HCBS) waivers that can offset the cost of care services delivered inside a licensed community. Eligibility, waitlists, and covered services vary — check directly with the state Medicaid agency.
