Psychiatric treatment for the elderly mainly includes pharmacotherapy and psychotherapy. Pharmacotherapy mainly involves the application of atypical antipsychotic drugs, such as olanzapine, quetiapine, risperidone, aripiprazole, etc. Because elderly people usually have underlying physical diseases, their metabolic ability is also reduced, and their liver and kidney functions are weaker, so they should apply atypical antipsychotic drugs with fewer side effects, and the starting dose of the drugs should be smaller than normal, and the dosage should be increased more slowly, and some physiological indicators, such as blood biochemistry and electrocardiogram, should be checked regularly during the medication period. Within the limits of the elderly’s health, we should try to treat them with a full course and dose. At the same time, psychotherapy, including supportive psychotherapy, can be carried out, and family members should be instructed to care for and accompany the elderly and take good care of their diet and living.
