What Is the Last Stage of Alzheimer's?

The last stage of Alzheimer's disease, also known as severe or late-stage Alzheimer's, involves severely limited cognitive and physical function, explains the Alzheimer's Association. People with late-stage Alzheimer's don't respond to environmental or conversational cues, and they often need help with basic physical activities, such as walking, bathing and eating.

Monitoring daily food intake is especially difficult for people with late-stage Alzheimer's, as they may forget to eat regularly, have trouble swallowing or lifting a fork, or lose focus halfway through chewing, notes the Alzheimer's Association.

Limited physical functioning means people with late-stage Alzheimer's need special assistance walking, sitting up and adjusting in bed to avoid bed sores. Sweat and other bodily fluids cause rashes if left unattended, explains the Alzheimer's Association. Due to their extensive daily needs, people with late-stage Alzheimer's often fare better in a care facility.
