Which of the following is a common behavioral symptom of Alzheimer's disease?

• A. Aggression
• B. Forgetfulness
• C. Weight change
• D. Hunger

Answer: (A)

Alzheimer's disease often brings behavioral and neuropsychiatric changes as the condition progresses. These changes reflect how the brain regions that regulate emotion and behavior are affected, not just memory problems. Aggression is a behavior that can emerge as patients struggle with communication, frustration, or confusion, making it a recognizable behavioral symptom of the disease.

Forgetfulness, by contrast, points to memory impairment, which is a cognitive symptom rather than a behavior. Weight change and hunger aren’t defining behavioral features of Alzheimer's and can arise from many unrelated factors. In practice, if aggression appears, addressing triggers, ensuring safety, and seeking medical guidance for management are important steps, alongside strategies to support the person’s communication and routine.
