Final answer:
Alzheimer's disease is a neurodegenerative disorder that affects the brain and generally follows a predictable route, although the rate and symptoms can vary among individuals.
Step-by-step explanation:
Altzheimer's disease is a neurodegenerative disorder that affects the brain. It is characterized by a gradual decline in cognitive abilities, memory loss, and changes in behavior. While the progression of the disease can vary from person to person, it generally follows a predictable route. The disease typically begins with mild memory problems and confusion, which then worsen over time. As the disease progresses, individuals may experience difficulty with language and speech, as well as problems with judgment and thinking. In the later stages, individuals may lose the ability to carry out daily activities and require assistance with their care. However, it is important to note that while there is a general pattern to the progression of Altzheimer's disease, the exact rate and symptoms can vary among individuals.
