Which of the following is a symptom of caffeine intoxication?

• A. Restlessness
• B. Hearing voices
• C. Loss of appetite
• D. Memory deficit

Answer: (A)

Caffeine is a stimulant, and intoxication arises after consuming a high dose that leads to marked CNS arousal and autonomic symptoms. Restlessness is a classic manifestation of this stimulant effect, reflecting the heightened nervous system activity and need for movement or agitation that caffeine can provoke. Among the given options, restlessness best fits the pattern of caffeine intoxication.

Hearing voices would be hallucinations, which are not typical of caffeine intoxication. Loss of appetite and memory deficit aren’t defining features of caffeine intoxication; caffeine can influence appetite or transient cognitive performance, but these are not core diagnostic symptoms.
