What neurotransmitter was first believed to be the cause of schizophrenia?

  • A. GABA
  • B. Serotonin
  • C. Epinephrine
  • D. Dopamine
Correct Answer: D

Rationale: The correct answer is Dopamine. Dopamine was initially thought to be the primary cause of schizophrenia. This neurotransmitter hypothesis was based on the observation that drugs that increase dopamine activity can worsen symptoms of schizophrenia, while drugs that decrease dopamine activity can improve symptoms. Choices A, B, and C are incorrect because GABA, serotonin, and epinephrine were not the neurotransmitters initially believed to be the cause of schizophrenia.
