The evidence on this question is mixed and depends heavily on the quality of the care home and the circumstances of the move. Some studies suggest that people admitted to care homes in a crisis may appear to decline quickly, but this often reflects deterioration that was already underway before admission. A well-run dementia care home with trained staff, therapeutic activities, good nutrition, and consistent routines can slow functional decline and improve quality of life. Poorly run homes with high staff turnover and limited stimulation are associated with worse outcomes. Careful, well-planned admission with familiar objects and consistent staff involvement helps minimise disruption.
