Which of the following is NOT a symptom of Alzheimer's disease?

Visual hallucinations are not typically associated with Alzheimer's disease, making this answer correct. Alzheimer's disease primarily presents with a gradual decline in cognitive functions, including memory loss, confusion regarding time and place, and difficulties with language. These symptoms align with the progressive nature of Alzheimer's, where patients may forget recent events, become disoriented, and struggle to find the right words during conversations.

In contrast, visual hallucinations are more commonly associated with other types of dementia, such as Lewy body dementia or certain psychiatric conditions. While individuals with Alzheimer's may experience varied symptoms, the presence of visual hallucinations is not a hallmark feature and usually indicates a different underlying issue.
