Stage 7: Very Severe Cognitive Decline (Late-stage of Alzheimer’s Disease)
This is the last stage of Alzheimer’s disease, in which the patient loses the ability to respond to the environment, talk, and eventually control body movements. Even at this stage, words and sentences may still be spoken.
Patients at this stage require almost general routine care, including diet and toilet use. They may not be able to smile, sit without help, or keep head facing forward, abnormal reflex reaction, muscles become stiff, difficulty swallowing, amongst others.
