A group of nursing students is reviewing the various theories related to the etiology of schizophrenia. The students demonstrate understanding of the information when they identify which neurotransmitter as being responsible for hallucinations and delusio
A) Dopamine
B) Serotonin
C) Norepinephrine
D) Gamma-aminobutyric acid (GABA)
Ans: A
Although research is demonstrating that schizophrenia does not result from dysregulation of a single neurotransmitter or biogenic amine (such as serotonin, norepinephrine, or dopamine), positive symptoms of schizophrenia, specifically hallucinations and delusions, are thought to be caused by dopamine hyperactivity in the mesolimbic tract. Researchers are also hypothesizing a role for GABA but have yet to identify any specific information.
