Atypical antipsychotics, also known as the second generation of new antipsychotics, have fewer side effects, better efficacy on patients’ psychiatric symptoms, and unique cognitive improvement compared to typical antipsychotics. Olanzapine, quetiapine, aripiprazole, ziprasidone, clozapine, paliperidone, etc. are often used, which have broader effects, better efficacy, and better safety than traditional antipsychotics, and are currently the drugs of choice in clinical practice.
