Memory care is a subset of assisted living where the services are designed specifically for residents suffering from dementia or Alzheimer's. Memory care is often provided in a secure neighborhood (to prevent wandering) with unique design features and requirements for staff training. Since memory care residents require more assistance than assisted living residents, memory care is often more expensive. In addition, memory care apartments tend to be smaller (250 sf - 600 sf) versus assisted living apartments (250 sf - 1,200. sf). Occasionally, memory care is provided in a nursing home, but this is usually the most expensive solution.
