During which stage of Alzheimer's disease are individuals likely to have noticeable problems coming up with the right words?

In Stage 3 of Alzheimer's disease, individuals experience noticeable cognitive decline, which includes significant challenges with communication and language. This stage is characterized by individuals having trouble coming up with the right words during conversations and may struggle to recall names or follow the flow of dialogue. This ability to communicate effectively is impacted as the disease progresses, making it increasingly difficult for individuals to express themselves verbally.

In earlier stages, such as Stage 1 and Stage 2, individuals may exhibit mild memory lapses or cognitive issues, but they often retain their ability to communicate basic thoughts and feelings. By Stage 4, although there are further declines in cognitive function, the noticeable word-finding difficulties are already prominent in Stage 3 and continue to worsen. Therefore, Stage 3 is pivotal as it marks a clear and observable shift in the ability to use language effectively, making it the correct answer for this question.
