Abstract |
Persistent cognitive deficits are prevalent during all stages of bipolar disorder (BD). However, few studies have examined subjective cognitive complaints in patients with BD. This study aimed to investigate the prevalence and relevant factors of subjective cognitive functioning and its potential effects on predicting psychosocial functioning and suicidal ideation in BD. Ninety-two patients with BD type I (including 42 depressed patients and 50 euthymic patients) and 60 healthy individuals were recruited for this study. All participants were assessed with a battery of neuropsychological tests examining attention and processing speed, visual memory, working memory and executive functions, as well as the Cognitive Complaints in Bipolar Disorder Rating Assessment, the Global Assessment of Functioning scale and the Beck Scale for Suicide Ideation. Bipolar patients exhibited worse subjective cognitive dysfunction compared with healthy individuals, and depressed patients expressed more cognitive complaints than euthymic bipolar patients. In bipolar group, psychosocial functioning, suicidal ideation and occupational status were the main relevant factors of subjective cognitive functioning. Subjective cognitive functioning could also predict psychosocial functioning and suicidal ideation. Depressive symptoms moderated the associations between objective cognitive functioning and suicidal ideation, but could not moderate the correlations between cognitive functioning and psychosocial functioning. These findings suggest that subjective cognitive assessment should be further emphasized in clinical practice. Language: en |
