Patients with bipolar disorder (BD) have a wide range of neurocognitive dysfunction, which lead to impaired psychosocial function and reduced quality of life. Therefore, improving neurocognitive function has become an important goal of BD treatment. Aiming at this, some clinical studies have been performed but failed to illustrate significant positive efficacies of pharmacological therapy or non-pharmacological therapy, which could attribute in part to insufficient understanding on the risk factors that affect the neurocognitive function of BD patients. Delayed diagnosis of BD is so common that a lot of patients receive long-term antidepressant treatment before of diagnosis of unipolar depression. There is controversy about whether antidepressant treatment in early stage would affect the neurocognitive function of BD patients. In view of the high prevalence of delayed diagnosis and the use of antidepressants, it is of great scientific significance and clinical value to clarify this matter and other factors that may potentially affect the neurocognitive function of BD patients.
