Which symptom is most likely displayed by individuals with Stage 3 Alzheimer's disease?

Individuals with Stage 3 Alzheimer's disease commonly exhibit confusion and disorientation as their cognitive decline progresses. At this stage, individuals often struggle with recognizing familiar places and people, leading to increased confusion about their surroundings or situation. This disorientation can manifest in various ways, such as getting lost in familiar environments or having difficulty following conversations.

While memory loss is a symptom observed throughout all stages of Alzheimer's, it becomes more pronounced and impactful in earlier stages rather than being the hallmark of Stage 3. Difficulty in speaking and altered sleep patterns can also occur, but they are typically more prominent in later stages or are not as defining as confusion and disorientation at this specific stage. Thus, confusion and disorientation serve as key indicators of the challenges faced by individuals in Stage 3 of the disease, highlighting the cognitive disturbances associated with this phase.
