Final answer:
Excessive amounts of dopamine in the brain have been proposed as a cause of schizophrenia. Treatment for the disease usually requires antipsychotic medications that work by blocking dopamine receptors and decreasing dopamine neurotransmission in the brain.
Step-by-step explanation:
Excessive amounts of dopamine in the brain have been proposed as a cause of schizophrenia. Schizophrenia is a serious mental illness characterized by symptoms such as hallucinations, delusions, and problems with social situations. The development of schizophrenia is thought to involve malfunctioning dopaminergic neurons and may also involve problems with glutamate signaling. Treatment for the disease usually requires antipsychotic medications that work by blocking dopamine receptors and decreasing dopamine neurotransmission in the brain.
