Dementia
Late

People with late-stage dementia typically turn increasingly inward and need assistance with most or all of their personal care. People with dementia in the late stages usually need 24-hour supervision to ensure their personal safety, and meeting of basic needs. If left unsupervised, they may wander or fall; may not recognize common dangers such as a hot stove; or may not realize that they need to use the bathroom and become incontinent. They may not want to get out of bed, or may need assistance doing so. Commonly, the person no longer recognizes familiar faces. They may have significant changes in sleeping habits or have trouble sleeping at all.

Changes in eating frequently occur. Cognitive awareness is needed for eating and swallowing and progressive cognitive decline results in eating and swallowing difficulties. This can cause food to be refused, or choked on, and help with feeding will often be required. For ease of feeding, food may be liquidized into a thick purée. They may also struggle to walk, particularly among those with Alzheimer's disease. In some cases, terminal lucidity, a form of paradoxical lucidity, occurs immediately before death; in this phenomenon, there is an unexpected recovery of mental clarity.
