Question

Manny has been diagnosed with schizophrenia. His psychiatrist believes that Manny's hallucinations and perceptual distortions may be caused, in part, by _____ amounts of the neurotransmitter _____.

a) Excessive; dopamine
b) Deficient; serotonin
c) Abnormal; acetylcholine
d) Elevated; norepinephrine

Answer 1

Excessive amounts of dopamine may contribute to Manny's hallucinations and perceptual distortions in schizophrenia. Antipsychotic medications that block dopamine receptors are often used to treat the disease.

Step-by-step explanation:

Manny's hallucinations and perceptual distortions may be caused, in part, by excessive amounts of the neurotransmitter dopamine. Schizophrenia is a mental illness characterized by symptoms such as hallucinations, delusions, and problems with social situations. Research suggests that dopamine dysfunction plays a role in the development of schizophrenia. Treatment for the disease involves antipsychotic medications that work by blocking dopamine receptors and decreasing dopamine neurotransmission in the brain.
