Longman Dictionary of Contemporary English
Residential care refers to long-term care given to adults or children who stay in a residential setting rather than in their own home or family home.
There are various residential care options available, depending on the needs of the individual. People with disabilities, mental health problems, learning difficulties, Alzheimers, dementia or who are frail aged are often cared for at home by paid or voluntary caregivers, such as family and friends, with additional support from home care agencies. However, if home-based care is not available or not appropriate for the individual, residential care may be required.
