A growing group of Al researchers think they know where the field went wrong.

[单项选择]In the 1950s, the development of antipsychotic drugs called neuroleptics(抑制精神病药物 )radically changed the clinical outlook for patients in mental institutions who had previously been considered hopelessly psychotic. Daily medication controlled delusions and made psychotherapy possible. Many who otherwise might never have left institutions returned to society. Now physicians have learned that there is a price to be paid for these benefits. Approximately 10 to 15 percent of patients who undergo long-term treatment with antipsychotic drugs develop a cluster of symptoms called tardive dyskinesia (迟发性运动障碍), the most common symptoms of which are involuntary repetitive movement of the tongue, mouth, and face, and sometimes the limbs and trunk.
Neuroleptic drugs interfere with the action of dopamine (多巴胺) , an important neurotransmitter in the brain, by binding to the dopamine receptors of nerve cells, and dopamine is a prime suspect in the pathophysiology of schizophrenia. Large doses of d
A. psychological effect on the patient
B. long-term therapeutic use of drugs
C. addiction of a patient to dopamine
D. physical injuries caused by violent muscle spasms
