Schizophrenia is a chronic and severe mental disorder that often occurs in adolescence or early adulthood, with a lifetime prevalence of 1%. More than half of patients experience mental disabilities, which have varying degrees of impact on themselves, their families, and society. Cognitive impairment is one of the core symptoms of schizophrenia and an important cause of mental disability, which has adverse effects on the daily functioning and overall clinical outcomes of schizophrenia patients. In recent years, cognitive impairment has become a research hot spot in the field of schizophrenia. More and more evidences suggest that cognitive impairment already exists in patients' childhood and continues to affect their condition and social functioning. Most treatment interventions for cognitive impairment in schizophrenia, including the use of medication and non-medication therapies, have varying effects and lack precise and effective intervention methods. In this article, we provide a descriptive review of the treatment measures for cognitive impairment in schizophrenia and offer some suggestions on how future work can improve cognitive dysfunction in schizophrenia.
