Risperidone generally does not affect the brain’s thinking. If abnormal thinking occurs, it is usually due to disease symptoms, and whether the drug can be discontinued should be judged by a medical professional. Risperidone is a second-generation antipsychotic, and the main adverse effects of this drug are agitation, insomnia and hyperprolactinemia. Extrapyramidal reactions, such as acute dystonia, sedentary inability, and Parkinson’s-like disorder, can occur at higher doses of the drug and do not usually affect the brain. If side effects of these drugs occur, symptomatic management with other drugs is usually recommended. In addition, the timing of discontinuation of risperidone needs to be determined by a physician based on the patient’s specific condition and should be gradual, but most patients require long-term medication due to the recurring nature of the disease. After the patient stops taking risperidone as prescribed by the doctor, family members should pay attention to the patient’s sleep, diet, mood and other changes at night, and if they find any relapse, they should immediately consult the doctor.
