The late-stage of Alzheimer's disease, which slowly develops in three general stages, involves the inability to respond to surroundings, hold a conversation and control movement, notes the Alzheimer's Association. Patients in the final stage of the disease find it hard to express pain, but they may still utter words. Their memory and cognitive abilities steadily deteriorate, and they tend to experience personality changes.
During the late-stage of Alzheimer's disease, patients need complete assistance with normal activities, according to the Alzheimer's Association. They need 24/7 personal care as they slowly fail to grasp the events around them and their recent experiences. They find it difficult to walk and sit, and they eventually cannot swallow properly. They also become susceptible to pneumonia and other infections.
Patients in the early-stage of the disease typically have the skills to perform daily activities, such as working, driving or attending social activities, states the Alzheimer's Association. However, they notice memory lapses, particularly forgetting common words or the locations of frequently seen objects. They also experience difficulty in recalling names of new acquaintances.
During the middle-stage, patients often misuse words, easily become frustrated or show strange behaviors, such as not wanting to bathe, explains the Alzheimer's Association. They tend to forget things frequently, experience mood swings, feel confused about the time of day or their locations, and suffer problems with bladder and bowel control.
