Abstract
BACKGROUND Adults with bipolar disorder (BD) commonly present with cognitive deficits. Many also report subjective or perceived cognitive failures. For this study, we identified four distinct clusters of adults with BD on the basis of both BD symptoms (depression and hypo/mania) and perceived cognitive errors (i.e., forgetfulness, distractibility, false triggering). We hypothesized that participants reporting more BD symptoms and cognitive errors would report lower psychological well-being (i.e., self-efficacy, life scheme, life satisfaction). A second objective was to determine if and how clusters differed in terms of BD related factors (e.g., subtypes, sleep, medications) and sociodemographic differences such as age of participants. From the BADAS (Bipolar Affective Disorder and older Adults) Study, we identified 281adults with BD (M = 44.27 years of age, range 19-81), recruited via social media. RESULTS All clusters significantly differed across all grouping variables except symptoms of hypo/mania due to low frequency. Across clusters, perceived cognitive failures and BD symptoms increased in lockstep; that is, those reporting more cognitive errors also reported significantly higher symptoms of both depression and hypo/mania. As hypothesized, they also reported significantly lower psychological well-being. CONCLUSIONS Age did not significantly differ across clusters in contrast to existing research in which cognitive loss is objectively measured. That is, perceived cognitive errors are significantly associated with lower psychological well-being for both young and older adults with BD.

J Clin Exp Neuropsychol 2024; 46:557-569.

Abstract
OBJECTIVES Patients with Somatic Symptom and Related Disorders (SSRD) report subjective cognitive concerns, and research indicates that they show objective cognitive impairment. This study explored the value of subjective concerns flagging objective impairment. Furthermore, we investigated whether coping moderated this relationship, and the role of depressive symptomatology. METHOD In a cross-sectional design, objective impairment was measured with an extensive neuropsychological assessment; subjective concerns with the Cognitive Failure Questionnaire; coping styles with the Coping Inventory of Stressful Situations; and symptoms of depression with the Patient Health Questionnaire- 9. RESULTS The results show that subjective concerns are of limited value in signaling objective impairment in patients with SSRD. Regression analyses performed on data from 225 patients showed that symptoms of depression (β = .32) were the main predictor of subjective concerns, which were unrelated to objective impairment. Coping was not a moderator, but patients with emotion-oriented coping styles had more subjective concerns (β=.40), and conversely, patients with avoidance- and/or task-oriented coping styles had less (respectively, β=-.27 and β=-.24). CONCLUSIONS These results align with the Somatosensory Amplification Theory; patients with SSRD may amplify benign cognitive failures and experience them as intrusive, noxious, and more intense. In patients with SSRD, subjective cognitive concerns are more related to psychological constructs (symptoms of depression and coping styles) than to objective impairment.

Factors associated with the discrepancy between objective and subjective cognitive impairment in bipolar disorder. J Affect Disord 2024; 349:210-216. [PMID: 38190862 DOI: 10.1016/j.jad.2024.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 11/27/2023] [Accepted: 01/03/2024] [Indexed: 01/10/2024]
Abstract
OBJECTIVE The aim of this study is to evaluate the discrepancy between objective cognitive measures and cognitive subjective complaints in a sample of euthymic patients with bipolar disorder (BD). METHODS One hundred and sixteen participants (83 euthymic patients with BD and 33 healthy controls) were enrolled for this study. Patients were assessed with a comprehensive neuropsychological battery and they also reported their subjective cognitive complaints with the Cognitive Complaints in Bipolar Disorder Rating Scale (COBRA). The discrepancy between objective and subjective data was calculated using a novel methodology proposed in a previous study (Miskowiak, 2016). Statistical analyses included Pearson correlations and multiple linear regression. RESULTS Higher number of previous depressive episodes was identified as one variable associated with the global sensitivity composite score (Beta = 0.25; t = 2.1; p = 0.04) and with the verbal learning and memory sensitivity score (Beta = 0.26; t = 2.16; p = 0.03). That is, patients with more previous depressive episodes tend to over-report cognitive complaints. In contrast, higher number of previous hospitalizations was associated with stoicism in the global total score (Beta = -0.27; t = -2.24: p = 0.029) and in the domain of attention/processing speed (Beta = -0.34; t = -2.52; p = 0.016), indicating patients with more hospitalizations tend to report less cognitive complaints. DISCUSSION Our study identified some factors that might help to explain the discrepancy between objective and subjective cognitive measures in BD, including number of previous depressive episodes and number of previous hospitalizations. This highlights the need of the combined use of both types of cognitive measures to make an accurate assessment of cognitive dysfunctions and their effective treatment.

Abstract
Background Studies comparing objective and self-reported cognitive functioning as well as influencing factors in individuals with remitted bipolar disorder are scarce and contradictory. Methods The aim of this study was to compare executive functioning and other objective and self-reported cognitive impairment between 26 individuals with remitted bipolar disorder (15 BD I) and 24 healthy controls using a cross-sectional design. Executive functions were measured by the TAP Go/No-go subtest as well as the Stroop Task. Self-rated functioning was assessed using the Attention Deficit Experience Questionnaire. In addition, possible predictors of self-reported and objective cognitive functioning were examined to perform regression analyses. Results Individuals with remitted bipolar disorder did not differ significantly in executive functions or other objective cognitive domains from the healthy control group, but showed a significantly lower level of self-reported cognitive functioning and self-esteem. While self-esteem was the strongest predictor in healthy controls for self-reported cognitive functioning, severity of illness and subthreshold depressive mood were the most important predictors in individuals with remitted bipolar disorder. Conclusion The results once again demonstrate the cognitive heterogeneity in bipolar disorder. In the treatment of cognitive deficits, factors such as subthreshold depressive symptomatology and self-esteem should be focused on in addition to cognitive training in remitted patients.

Abstract
Cognitive Failures Questionnaire (CFQ) is a widely utilized tool to measure the frequency of everyday cognitive lapses. Here we present a validation study of the Hungarian translation of CFQ. A subsample (n = 157) filled out the questionnaire twice within a 7-21 days interval to determine test-retest reliability. Exploratory structural equation modeling (ESEM) method was run on a larger sample (n = 382) for testing a different number of potential factors. Although the multiple-factor solutions showed good fit, the one-factor solution described the data more adequately. The composite reliability of the final model (CR = .822) as well as test-retest reliability (intraclass correlation coefficient = .900) and the internal consistency (Cronbach's alpha = .920) of the CFQ were high. Higher CFQ scores (i.e., more cognitive slips) correlated positively with anxiety and depression while a negative relationship was present with well-being. Furthermore, women were characterized with higher CFQ scores compared to men. Our results are in line with previous studies, and the excellent psychometric properties make the Hungarian version of CFQ an appropriate measure of cognitive failures.

Association between baseline cognitive symptoms and the subsequent presenteeism and global function in patients with major depressive disorder. J Psychiatr Res 2022; 154:324-331.

Abstract
Cognitive symptoms in major depressive disorder (MDD) contribute to impaired functional abilities and work productivity, particularly presenteeism. We investigated the association between baseline cognitive symptoms and subsequent presenteeism, and global functional impairment in Japanese patients with MDD from PERFORM-J (Prospective Epidemiological Research on Functioning Outcomes Related to Major Depressive Disorder in Japan) - a 6-month, multicenter, epidemiological study data. A total of 518 patients initiating antidepressant monotherapy (first-line or switched from another drug) were enrolled. Assessments include Perceived Deficits Questionnaire - Depression (PDQ-D) for cognitive complaints, Sheehan Disability Scale (SDS) for global function (analysed n = 318), and Work Productivity and Activity Impairment Questionnaire for presenteeism (analysed n = 122). A strong association between changes in presenteeism and changes in SDS scores (r: total = 0.636; work/school = 0.686) was observed. After adjusting for sociodemographic and MDD-related factors, patients without cognitive complaints at baseline showed lower odds of impaired presenteeism at 6 months versus patients with cognitive complaints (0.243, 95% CI: 0.079 to 0.747, p = 0.014) and also in patients with first episode of MDD against with recurrent MDD (0.327 (95% CI: 0.136 to 0.787). Similarly, patients without cognitive complaints had healthier global functioning (lower mean SDS total score) than patients with cognitive complaints (8.3 vs 11.2; 95% CI, -5.189 to -0.578; p = 0.014). First depressive episode (lower risk of presenteeism), being male, and low baseline SDS total score (better global functioning) were also associated with improved outcomes. These results highlight the potential value of baseline PDQ-D scores in predicting subsequent workplace and global functioning in patients undergoing treatment for MDD.

Abstract
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental conditions among school-age children. Early intervention and ongoing evaluation of treatment effectiveness are essential to minimize the life-long negative impact of ADHD. Neurocognitive functions have been reported to improve with pharmacological and cognitive training interventions for children with ADHD. We evaluated the value of measuring change in neurocognitive functions following ADHD interventions as a treatment outcome. We systematically reviewed randomized control trials of two distinctive types of ADHD interventions-pharmacological treatments and cognitive training-and summarized the changes in neurocognitive and clinical outcomes using a series of meta-analyses. Both pharmacological and cognitive training interventions showed positive effects on some aspects of neurocognitive functions. However, there were no significant correlations between changes in neurocognitive function (e.g., inhibition) and changes in ADHD behavioral symptoms (e.g., impulsive behavior). Although the associations between changes in neurocognitive function and clinical outcomes are not well studied, based on current findings, it is not suitable to use change in neurocognitive outcomes as a proxy for change in ADHD clinical symptom-based outcomes. There is, however, notable value in monitoring changes in neurocognitive function associated with ADHD interventions to achieve the following aims: (1) understanding full treatment effect on children with ADHD, (2) identifying ancillary indicators of subclinical changes, and (3) provision of objective and less biased measures of treatment effects. These findings are important evidence that changes in neurocognitive function could be a co-occurring objective indication that parallels the clinical effects of ADHD treatments.

Abstract
The aim is to assess whether instruments developed to measure subjective cognitive complaints (SCCs) and in neurology and aging can reliably be used in ADHD and other common psychiatric classifications. MEDLINE, PsycINFO, CINAHL and EMBASE+EMBASE CLASSIC were searched for relevant work on SCCs in psychiatric classifications (ADHD, autism, mood disorders, schizophrenia) in two phases: 1 identify instruments, 2 relevant studies. 35 studies with varying study quality were included. SCCs are most commonly studied in ADHD and mood disorders, but are found in all psychiatric classifications. SCCs show inconsistent and low associations to objective cognition across disorders, but higher and consistent relations are found with behavioral outcomes. SCCs are not qualitatively different for ADHD compared to other psychiatric classifications, and should thus not be seen as analogous to well validated measures of objective cognition. However, SCCs do reflect suffering, behavioral difficulties and problems experienced by across those with psychiatric problems in daily life.

Abstract
The determinants of metacognition are still poorly understood in bipolar disorders (BD). We aimed to examine the clinical determinants of metacognition, defined as the agreement between objective and subjective cognition in individuals with BD. The participants consisted of 281 patients with BD who underwent an extensive neuropsychological battery and clinical evaluation. To assess subjective cognition, participants provided a general rating of their estimated cognitive difficulties. Clinical characteristics of BD were also recorded, along with medication. We studied the potential moderation of the association between cognitive complaints and global objective cognitive performance by several clinical variables with ordinal logistic regressions. Depression and impulsivity were associated with greater cognitive complaints. The only variable that moderated the relationship between objective and subjective cognition in the global model was the prescription of antipsychotics. Patients taking antipsychotics had a poorer association between cognitive complaints and objective neuropsychological performance. This result suggests a role for dopamine in the modulation of metacognitive performance, and calls for the systematic control of antipsychotic medication in future studies documenting metacognitive deficits in severe and persistent mental disorders. Depression and impulsivity should be investigated as potential therapeutic targets for individuals with BD and cognitive complaints, before proposing an extensive neuropsychological evaluation.

Abstract
Nonadherence to medication regimens is frequently reported in bipolar I disorder (BDI) patients. However, little is known about the relationship between cognitive functions and adherence in BDI. To establish possible associations between medication adherence and cognitive function in patients with BDI. A total of 110 inpatients with BDI were subjected to the Structured Clinical Interview for DSM-IV Axis I Disorder, Morisky 8-Item Medication Adherence Scale, Young Mania Rating Scale, Wechsler Adult Intelligence Scale-Revised, Wechsler memory scale (WMS) and Wisconsin card sorting test (WCST). Patients were assessed on admission and followed up 6 months after discharge. Six months after discharge, (58.2%) of patients were nonadherent to their medications. The nonadherent group were younger males with less years of education, with lower mean scores in information orientation and visual memory backward domains of WMS and lower mean scores in perseveration responses, perseveration errors and learning to learn domains of WCST. In logistic regression analysis, younger age and impaired information orientation domain of WMS were putative predictors of nonadherence. Episodic memory and younger age were the strongest patients' related factors associated with nonadherence to medication. These results suggest that rehabilitation of specific cognitive skills may improve adherence in BDI.

Abstract
Background Metacognitive knowledge (MK; general awareness of cognitive functioning) and metacognitive experience (ME; awareness of cognitive performance on a specific cognitive task) represent two facets of metacognition that are critical for daily functioning, but are understudied in bipolar disorder. This study was conducted to evaluate MK and ME across multiple cognitive domains in individuals diagnosed with bipolar disorder and unaffected volunteers, and to investigate the association between metacognition and quality of life (QoL). Methods Fifty-seven euthymic participants with bipolar disorder and 55 demographically similar unaffected volunteers provided prediction and postdiction ratings of cognitive task performance across multiple cognitive domains. Self-ratings were compared to objective task performance, and indices of MK and ME accuracy were generated and compared between groups. Participants rated QoL on the Quality of Life in Bipolar Disorder Scale (QoL.BD). Results Metacognitive inaccuracies in both MK and ME were observed in participants with bipolar disorder, but only in select cognitive domains. Furthermore, most metacognitive inaccuracies involved underestimation of cognitive ability. Metacognitive indices were minimally associated with medication variables and mood symptoms, but several indices were related to QoL. Conclusions Individuals with bipolar disorder demonstrate inaccuracies in rating their cognitive functioning and in rating their online cognitive task performance, but only on select cognitive functions. The tendency to underestimate performance may reflect a negative information processing bias characteristic of mood disorders. Metacognitive variables were also predictive of QoL, indicating that further understanding of cognitive self-appraisals in persons with bipolar disorder has significant clinical relevance.

Abstract
The aim of the study was to investigate changes in both subjectively and objectively measured cognitive functions as well as their discrepancy in outpatients with major depression disorder in the course of cognitive-behavioural therapy (CBT). A neuropsychological test battery with cognitive tests measuring the domains of attention, memory, and executive functions as well as a questionnaire for the self-assessment of cognitive functions (FLei) in these domains were administered to depressed outpatients (n = 46) at the beginning of CBT, post-treatment after on average 40 sessions, as well as six months after the end of treatment. We found that subjectively as well as objectively measured cognitive functions did not change. The discrepancy between subjective and objective cognitive functions found at the beginning of therapy was no longer significant at post-treatment and six months later. The results indicate, that self-perceived and neuropsychologically measured cognitive impairments show stability despite improved depression. Specific interventions such as cognitive remediation therapy should be additionally applied to depressed patients who suffer from cognitive deficits.

Abstract
BACKGROUND Older adults with bipolar disorder (BD) commonly present with cognitive deficits (e.g., attention, memory, verbal fluency). Concomitantly, older adults with BD commonly report subjective or perceived cognitive failures. For this study, we confirmed a 3-factor model of cognitive failures first validated with older adults free of mental illness (i.e., forgetfulness, distractibility, false triggering). We then computed a structural equation model (SEM) demonstrating the construct validity of perceived cognitive errors in relation to quality of life with BD. Use of SEM enabled us to measure quality of life broadly and germane to BD (i.e., well-being, life satisfaction, alcohol misuse, sleep quality). METHODS We obtained responses from an international sample of 350 older adults with BD (M = 61.26 years of age, range 50-87), recruited via micro-targeted social media advertising. Most lived in Canada, the U.S., U.K., Ireland, Australia and South Africa. RESULTS As hypothesized, perceived cognitive failures were predicted by BD symptoms (depression and hypo/mania). And cognitive failures directly and indirectly predicted quality of life. LIMITATIONS Future research is needed to replicate this QoL model over time with younger patients and those recruited using more traditional methods. CONCLUSIONS Perceived cognitive failures may not be strongly correlated with objective indices of cognitive deficits; nonetheless perceived cognitive failures are significantly associated with quality of life for older adults with BD. For both cognitive errors and BD symptoms, their indirect effect on quality of life (via suicide ideation) is greater than the direct effect.

Abstract
Background Cognitive impairments in patients with bipolar disorder (BD) have been associated with reduced functioning. Aims: To investigate the association between (1) patient-evaluated cognitive function measured daily using smartphones and stress, quality of life and functioning, respectively, and (2) patient-evaluated cognitive function and objectively measured cognitive function with neuropsychological tests. Methods Data from two randomized controlled trials were combined. Patients with BD (N = 117) and healthy controls (HC) (N = 40) evaluated their cognitive function daily for six to nine months using a smartphone. Patients completed the objective cognition screening tool, the Screen for Cognitive Impairment in Psychiatry and were rated with the Functional Assessment Short Test. Raters were blinded to smartphone data. Participants completed the Perceived Stress Scale and the WHO Quality of Life questionnaires. Data was collected at multiple time points per participant. p-values below 0.0023 were considered statistically significant. Results Patient-evaluated cognitive function was statistically significant associated with perceived stress, quality of life and functioning, respectively (all p-values < 0.0001). There was no association between patient-evaluated cognitive function and objectively measured cognitive function (B:0.0009, 95% CI 0.0017; 0.016, p = 0.015). Patients exhibited cognitive impairments in subjectively evaluated cognitive function in comparison with HC despite being in full or partly remission (B: − 0.36, 95% CI − 0.039; − 0.032, p < 0.0001). Conclusion The present association between patient-evaluated cognitive function on smartphones and perceived stress, quality of life and functional capacity suggests that smartphones can provide a valid tool to assess disability in remitted BD. Smartphone-based ratings of cognition could not provide insights into objective cognitive function.

Abstract
BACKGROUND Studies comparing objective and subjective cognition in major depressive disorder (MDD) are scarce, and available data concern different cognitive functions but not decision-making specifically. This cross-sectional study aimed to explore objective (O-DMI) and subjective decision-making impairment (S-DMI) as well as the discrepancy between both in people with MDD. Secondly, we assessed the association between S-DMI and O-DMI. Finally, we explored sociodemographic, clinical, and psychosocial factors related to decision-making impairment status. METHOD One hundred and nine people with MDD were assessed with the Iowa Gambling Task to identify "O-DMI". The item 9 of the Beck Depression Inventory was used to compose the variable "S-DMI". Psychiatric history, medication adherence, childhood trauma, physical and psychological pain, and negative life experiences were also collected. RESULTS Forty-six percent of participants have O-DMI and 65.1% S-DMI. From 49.5% showing a discrepancy between both, 68,6% have positive discrepancy and 31,4% negative (i.e. under and overestimation respectively). O-DMI and S-DMI were not associated. Binary logistic regressions showed that the number of negative life events in the past 6 months was predictor of O-DMI, while depression severity and medication adherence predicted S-DMI. Finally, medication adherence and depression severity predicted the type of discrepancy. LIMITATIONS The variable S-DMI was obtained through a single item. CONCLUSION These results confirm the lack of association between objective and subjective measures of cognition in MDD, and for the first-time concerning decision-making. This suggest that both assessments should be done in order to have a deeper knowledge of the cognitive functioning of each patient.

Abstract
Introduction: The role of acute mood states as mediating factors in cognitive impairment in patients with mania or depression is not sufficiently clear. Similarly, the extent to which cognitive impairment is trait or state-specific remains an open question. Therefore, the aim of this study was to investigate the effect of a mood-induction on attention in patients with an affective disorder.Methods: Twenty-two depressed bipolar patients, 10 manic bipolar patients, 17 with a depressive episode (MDE), and 24 healthy controls performed the Attention-Network-Test (ANT). In a within-participants design, elated and sad moods were induced by an autobiographic recall and measured on a self-report scale. Subsequently, participants performed the ANT again.Results: The modulating effect of the elated mood induction on attention was small. Only the MDE group displayed moderate improvements in selective attention and tonic alertness. Surprisingly, after the sad mood induction, patients with MDE improved moderately on phasic and tonic alertness. Phasic alertness was also enhanced in patients with mania. Finally, after the mood induction, patients with MDE showed the largest variability in attentional performance.Conclusions: Results showed only small effects of mood induction on attention. This supports the view that attention deficits reflect trait variables.

Abstract
BACKGROUND The current paper briefly summarizes the literature on the neurocognitive deficit and its treatment in BD patients. METHODS The material was chosen on the basis of previous systematic reviews the author has taken part in. RESULTS The data so far suggest that the deficit is qualitatively similar but quantitatively milder in comparison to schizophrenia, it is present already since the first episode, is weakly related to mood symptoms and somewhat stronger to psychotic symptoms, it probably determines much of the disability and treatment is problematic. This deficit is also present during periods of euthymia. The possible adverse effect of psychotropic medication is rather small if any at all and is confounded by the specific clinical symptoms, for which medication is used for their treatment. This is especially true concerning antipsychotics and psychotic symptoms. The origin and the etiopathogenesis of the core neurocognitive impairment remain elusive. The presence of a neurodegenerative and of a neurodevelopmental component has both data in favor and against and they are both the focus of debate. CONCLUSIONS Treatment of the neurocognitive deficit and restoration of functioning is problematic. The data are limited and treatment options are few and with a weak overall effect. Pharmacological treatments, ECT and rTMS present some hard data, while the literature is inconclusive concerning psychotherapeutic interventions.

Abstract
Insight is greatly impaired in Bipolar Disorder (BD), especially during mania. Cognitive impairment is also present in BD. Despite that, few studies have investigated a possible association between these two aspects. The main goal of the current study is to compare BD affective states regarding performance in cognitive testing and investigate clinical and cognitive predictors for insight loss in BD. The study investigated a sample of 65 patients who were evaluated in one of the BD phases (mania, euthymia or depression). All the subjects underwent neuropsychological evaluation and completed the Insight Scale for Affective Disorders (ISAD). The relationship between level of insight and clinical/cognitive variables was analyzed through multiple regression models. No significant differences were found among BD phases regarding performance on cognitive testing. Insight was more impaired in mania then in depression or euthymia. Predictors for loss of insight were: severity of manic symptoms and impairments in selective attention (Symbol search test), divided attention (Trail making test) and inhibition (Stroop test). The sample size is a potential limitation of the current study. Nevertheless, the results suggest this had limited impact, with group differences being detected for a number of variables. The results found have important clinical importance, suggesting, for example, that rehabilitation of specific cognitive skills may improve insight in BD.

Abstract
BACKGROUND Patients may present cognitive deficits during all stages of bipolar disorder (BD). Few studies have examined self-reported cognitive difficulties and its relation to neurocognitive dysfunction during symptomatic periods of BD. This study aimed to compare subjective cognitive functioning and explore associations between subjective and objective cognitive functioning across different BD clinical states, and investigate the predicting and moderating roles of mood symptoms. METHODS Subjective cognitive functioning (measured by Cognitive Complaints in Bipolar Disorder Rating Assessment, COBRA) and several domains of cognitive functioning (assessed by a neuropsychological battery), including executive functions, attention and processing speed, and visual memory, were examined in 48 hypomanic or manic patients, 42 depressed bipolar patients, 50 euthymic bipolar patients and 60 healthy comparisons. RESULTS All patients exhibited subjective and objective cognitive deficits in relation to healthy comparisons. There was a significant association between subjective and objective cognitive functioning in euthymic group, but the association was not significant in acute symptomatic groups, which could be moderated by depressive or manic symptoms in depressive or manic group, respectively. Subjective cognitive functioning was significantly correlated with mood symptoms, and the best predictor of subjective cognitive functioning was depressive symptoms. LIMITATIONS This was a cross-sectional study with a mixed sample of inpatients and outpatients. The medication effect was not adjusted. CONCLUSIONS The associations between subjective and objective cognitive dysfunction varied in clinical states, and mood symptoms moderated the associations. A neuropsychological test battery is required to substantiate actual cognitive dysfunction in clinical settings, irrespective of subjective cognitive deficits.

Abstract
BACKGROUND Bipolar disorder (BD) is associated with significant neurocognitive and functional impairment, which may progress across stages. However, the potential progression of subjective cognitive complaints and quality of life (QoL) has not been addressed. Our main objective was to assess subjective cognitive complaints and QoL on euthymic patients with BD and their healthy siblings. METHODS Four groups were compared: euthymic patients with type I BD in the early (n = 25) and late (n = 23) stages, their healthy siblings (latent stage; n = 23) and healthy controls (n = 21). Cognitive complaints and QoL were assessed using the COBRA and WHO-QoLBREF questionnaires, respectively. RESULTS Late-stage patients had greater number of subjective cognitive complaints and reported a worse QoL compared to the other groups. Early-stage patients also had more cognitive complaints than controls and siblings, although differences were not significant. Siblings and controls reported similar QoL. LIMITATIONS the most important limitation of this study is the criterion used to define the early and late stages of BD, as currently there is no consensus and previous studies have used different criteria. CONCLUSIONS This is the first study to examine subjective cognition and QoL in patients with BD and siblings. Our results raise the possibility that burden of cognitive complaints increase with disorder progression, in tandem with deterioration in subjective QoL. That would support a clinical staging model of BD. This hypothesis remains to be confirmed by a longitudinal analysis.

Abstract
Objective: Cognitive symptoms in major depressive disorder (MDD) are common and may negatively impact clinical and functional outcomes. The Prospective Research Observation to Assess Cognition in Treated patients with MDD (PROACT) study aimed to assess the prevalence and course of cognitive symptoms, and their associations with clinical and functional outcomes during 6 months of antidepressant treatment, in a real-world setting among Chinese patients with MDD. Patients and methods: Outpatients (n=598) aged 18-65 years with MDD and a total score ≥17 on the Hamilton Depression Rating Scale - 17 Items (HAM-D17) were observed over 6 months after initiating new antidepressant monotherapy, with follow-up visits at months 1, 2, and 6. Cognitive symptoms were assessed using the Perceived Deficits Questionnaire - Depression (PDQ-D) and cognitive performance using the Digit Symbol Substitution Test (DSST). Results: At baseline, 76.9% of patients had indications of cognitive symptoms (PDQ-D total score ≥21); at month 6, this was reduced, but still present in 32.4%. Across the 6-month study period, patients improved across cognitive, clinical and functional assessments. High levels of cognitive symptoms (PDQ-D) consistently predicted worse clinical outcomes, ie, lower odds for remission and increased odds for relapse, as well as worse patient-reported functional outcomes and lower quality of life. In contrast, cognitive performance (DSST) predicted performance-based functioning but only a few patient-reported functional outcomes (absenteeism and quality of life), and no clinical outcomes. PDQ-D and DSST scores were uncorrelated at baseline. Conclusion: The study highlights the importance of assessing and targeting cognitive symptoms for increasing patients' chances of recovery and restoring functioning in the treatment of MDD. The results further highlight the relevance of complementary assessment methods to fully capture aspects of cognitive symptoms in patients with depression.

Abstract
OBJECTIVES Across age groups, bipolar disorder (BD) carries the greatest risk of death by suicide of all psychiatric conditions; 25%-50% of those with BD will make one or more suicide attempt. Psychometrically sound instruments are required to reliably measure suicide ideation and risk of self-harm for older adults with BD. For this study, we validate the geriatric suicide ideation scale (GSIS) with adults 50+ years with BD. METHODS We recruited a global sample of 220 older adults with BD (M = 58.50 years of age) over 19 days using socio-demographically targeted, social media advertising and online data collection. To demonstrate the construct validation of GSIS responses by older adults with BD, we computed correlations and performed regression analyses to identify predictors of suicide ideation. RESULTS Our analyses support a four-factor model of responses to the GSIS (ideation, death ideation, loss of personal and social worth, and perceived meaning in life) measuring a higher order latent construct. Older adults with BD reporting low satisfaction with life and current depressive symptoms, and who misuse alcohol, report significantly higher levels of suicide ideation. Sleep quality and cognitive failures are also correlated with GSIS responses. CONCLUSIONS Results support the factorial validity of the GSIS with older adults with BD. Similar to other populations, the GSIS measures a four-factor structure of suicide ideation. Across BD subtypes, the GSIS appears to reliably measure suicide ideation among older adults with BD.

Abstract
BACKGROUND It is well established that patients with either bipolar disorder (BD) or attention-deficit/hyperactivity disorder (ADHD) present functional impairment even when in remission. Nevertheless, research on functional impairment with adult patients with bipolar disorder comorbid to ADHD (BD+ADHD) is very scarce. The main objective of the current report was to evaluate the overall and specific domains of functioning, in patients with BD+ADHD compared to patients with pure bipolar disorder (pBD) and healthy controls (HCs). METHOD 162 subjects from 3 groups were compared: 63 pBD, 23 BD+ADHD and 76 HCs. All the patients with BD had been euthymic for at least 6 months and they were recruited at the Hospital Clinic of Barcelona. All the participants were assessed with the 17-item Hamilton Depression Rating Scale (HAM-D), the Young Mania Rating Scale (YMRS) and the Functioning Assessment Short Test (FAST). Clinical, and sociodemographic data were also recorded. RESULTS Clinical groups, pBD and BD+ADHD, showed lower overall functioning (p < 0.001) in each domain of the FAST scale compared to the HCs. Moreover, the Tukey post hoc test revealed that the BD+ADHD group showed a worse score than pBD in the cognitive domain of the FAST. However, after controlling for potential confounding variables, only the HDRS scores (p < 0.026) remained significant for the cognitive domain of the FAST. LIMITATIONS The small sample size of the comorbid BD+ADHD group. CONCLUSIONS Adult patients with BD+ADHD showed the worst scores in functioning compared with the HCs, but did not show more severe functional impairment than the pBD group except for the cognitive domain. Therefore our findings suggest that depressive symptoms in adults with BD+ADHD may negatively influence cognitive functioning. Further studies are needed to confirm our findings for the management of BD+ADHD.

Abstract
BACKGROUND Conflict findings of the impact of inhalational anesthetics on postoperative cognitive function are reported. No systematic review has been performed to solve the problem. The aim of the study was to assess the effect of different inhalational anesthetics on postoperative cognitive function in a network meta-analysis. METHODS We will search MEDLINE, EMBASE, the Central Register of Controlled Trials in the Cochrane library, and CINAHL for randomized controlled trials or cohort studies assessing the short-term or long-term cognitive function of elderly patients (over 60 years) receiving major surgeries and inhalational anesthetics (desflurane, isoflurane, sevoflurane, halothane, and nitrous oxide) during surgery. Two reviewers will independently screen study eligibility, extract information from eligible studies, and appraise study quality. The impact of inhalational anesthetics will be assessed through: incidence of postoperative cognitive dysfunction at 1 week, 3 months, 1 year, and over 1 year after surgery; incidence of post-operative delirium; test of postoperative cognitive function. RESULTS The results of this systematic review and meta-analysis will be published in a peer-reviewed journal. CONCLUSION To our knowledge, this systematic review will be the first to evaluate existing research on the incidence of postoperative cognitive function after inhalational anesthetics. Our study will assess the effect of different inhalational anesthetics on postoperative cognitive function. ETHICS AND DISSEMINATION The review will be finished in December 2017, and the result will be published in a peer-reviewed journal or disseminated through conference posters or abstracts.

Abstract
OBJECTIVES Bipolar disorder (BD) carries the greatest risk of death by suicide of all psychiatric conditions as 25%-50% of those with BD will make one or more suicide attempt, and about 15% will intentionally end their lives. Among young adults with BD, substance misuse, medication non-adherence, age at onset, and comorbid psychiatric conditions each predict self-harm. It is currently unclear if these same factors or others predict suicide ideation among older adults with BD. METHODS We recruited a global sample of 220 older adults with BD over 19 days using socio-demographically targeted, social media advertising and online data collection (Mean = 58.50, SD = 5.42; range 50 to 81 years). Path analyses allowed us to identify direct and indirect predictors of suicide ideation among older adults with BD. RESULTS Cognitive failures (perception, memory, and motor function), depressive symptoms, alcohol misuse, and dissatisfaction with life as direct predictors of suicide ideation; duration of BD symptoms and medication non-adherence emerged as indirect predictors. Of note, the significant impact of sleep on suicide ideation is indirect via depressive symptoms, cognitive failures, medication non-adherence and life dissatisfaction. CONCLUSIONS As with young adults with BD, alcohol misuse and medication non-adherence emerged as significant predictors of suicide ideation. In addition, cognitive failures directly and indirectly predict suicide ideation in this sample of older adults with BD. Population aging and treatment efficacy are leading to ever growing numbers of older adults with BD. Both direct and indirect predictors of suicide ideation need to be considered in future BD research and treatment planning.

Abstract
In Japan, there are currently no reliable rating scales for the evaluation of subjective cognitive impairment in patients with bipolar disorder. We studied the relationship between the Japanese version of the Cognitive Complaints in Bipolar Disorder Rating Assessment (COBRA) and objective cognitive assessments in patients with bipolar disorder. We further assessed the reliability and validity of the COBRA. Forty-one patients, aged 16-64, in a remission period of bipolar disorder were recruited from Hokkaido University Hospital in Sapporo, Japan. The COBRA (Japanese version) and Frankfurt Complaint Questionnaire (FCQ), the gold standard in subjective cognitive assessment, were administered. A battery of neuropsychological tests was employed to measure objective cognitive impairment. Correlations among the COBRA, FCQ, and neuropsychological tests were determined using Spearman's correlation coefficient. The Japanese version of the COBRA had high internal consistency, good retest reliability, and concurrent validity-as indicated by a strong correlation with the FCQ. A significant correlation was also observed between the COBRA and objective cognitive measurements of processing speed. These findings are the first to demonstrate that the Japanese version of the COBRA may be clinically useful as a subjective cognitive impairment rating scale in Japanese patients with bipolar disorder.

Abstract
Many patients with bipolar disorder (BD) experience debilitating cognitive deficits, with risk of impaired occupational and psychosocial functioning. However, knowledge of how these deficits impact the patients' ability to perform Activities of Daily Living (ADL), tasks related to self-care and domestic life is limited. We explored the relation between impaired cognitive function and the ability to perform ADL in patients with BD. A total of 42 outpatients (mean age 36 years (range 19.0-58.0 years), 69% women) with BD in remission and with subjective cognitive complaints (≥ 13 on the Cognitive Complaints in Bipolar Disorder Rating Assessment questionnaire (COBRA)) were included. Objective neurocognitive function was evaluated with a short comprehensive cognitive test battery and ADL ability was evaluated with the performance-based Assessment of Motor and Process Skills (AMPS) in the homes of the patients. Our findings indicate that low processing speed correlated with decreased ADL ability, and processing speed as measured by the cognitive test battery thus seems to be significantly related to patients' ability to live independently in the community. Overall, adding a performance based test to assess ADL ability in patients with BD home-surroundings seems to provide new insights regarding the effect of cognitive impairment in patients with BD.

Abstract
BACKGROUND Many patients with bipolar disorder (BD) experience residual symptoms during their inter-episodic periods. The study aimed to analyse the relationship between residual depressive symptoms, sleep disturbances and self-reported cognitive impairment as determinants of psychosocial functioning in a large sample of euthymic BD patients. METHODS This was a cross-sectional study of 468 euthymic BD outpatients. We evaluated the residual depressive symptoms with the Bipolar Depression Rating Scale, the sleep disturbances with the Pittsburgh Sleep Quality Index, the perceived cognitive performance using visual analogic scales and functioning with the Functioning Assessment Short Test. Structural equation modelling (SEM) was used to describe the relationships among the residual depressive symptoms, sleep disturbances, perceived cognitive performance and functioning. RESULTS SEM showed good fit with normed chi square=2.46, comparative fit index=0.94, root mean square error of approximation=0.05 and standardized root mean square residuals=0.06. This model revealed that residual depressive symptoms (path coefficient =0.37) and perceived cognitive performance (path coefficient=0.27) were the most important features significantly related to psychosocial functioning. Sleep disturbances were indirectly associated with functioning via residual depressive symptoms and perceived cognitive performance (path coefficient=0.23). CONCLUSIONS This study contributes to a better understanding of the determinants of psychosocial functioning during the inter-episodic periods of BD patients. These findings should facilitate decision-making in therapeutics to improve the functional outcomes of BD during this period.

Abstract
Several studies on cognition in bipolar disorder (BD) have been developed on the last decade. Neuropsychological evaluation of attention in BD patients is fundamental since alterations in attention affect other cognitive functions. Evaluate if performance of BD patients in attention tests varies according to each phase of the disease and verify if there are differences in attention when comparing BD patients with normal controls. The study included 101 BD patients, with ages between 18 and 65 years, being 52 euthymic, 22 manic and 27 depressive, besides 30 normal controls. All subjects were evaluated though Hamilton Depression Scale, Young Mania Rating Scale and Global Assessment of Functioning, bipolar version (CGI-BP). Attention was evaluated through a neuropsychological battery. Normal controls had a better performance in selective attention tests than BD patients. No differences were found among manic, depressive and euthymic phases. Attention is markedly impaired in BD. Nevertheless, the results of this study do not imply that the severity of the attention deficit in BD patients varies according to decease phase.

Abstract
This study aimed to identify the relationship between cognitive function and quality of life (QOL) in Chinese patients with bipolar disorder (BD) in the remission stage, by adopting disease-specific instruments. The remission stage was assessed using the Hamilton Depression Rating Scale (HAMD) and the Bech-Rafaelsen Mania Rating Scale (BRMS). One hundred euthymic bipolar patients and 115 healthy controls completed the "cognitive complaints in bipolar disorder rating assessment"(COBRA), Montreal Cognitive Assessment scale (MoCA), and "Brief version of Quality of Life in Bipolar Disorder" (Bref QOL.BD), which were used to assess the subjective cognitive function, objective cognitive function, and QOL, respectively. Compared to the healthy controls, the patient group had significantly lower total scores on both MoCA and Brief QOL.BD, and higher total score of COBRA. After controlling the influence of mood symptoms (HAMD and BRMS), both objective (MoCA) and subjective (COBRA) cognitive function could predict QOL significantly when entered either separately or simultaneously into hierarchical multiple regression models. When entered simultaneously, cognitive function explained 21% of the variance in QOL. The findings indicated that both objective and subjective cognitive function could influence QOL in euthymic bipolar patients, so continuous cognitive-improving interventions could help euthymic bipolar patients improve their QOL.

Abstract
OBJECTIVE The poor relationship between subjective and objective cognitive impairment in bipolar disorder (BD) is well-established. However, beyond simple correlation, this has not been explored further using a methodology that quantifies the degree and direction of the discrepancy. This study aimed to develop such a methodology to explore clinical characteristics predictive of subjective-objective discrepancy in a large BD patient cohort. METHODS Data from 109 remitted BD patients and 110 healthy controls were pooled from previous studies, including neuropsychological test scores, self-reported cognitive difficulties, and ratings of mood, stress, socio-occupational capacity, and quality of life. Cognitive symptom 'sensitivity' scores were calculated using a novel methodology, with positive scores reflecting disproportionately more subjective complaints than objective impairment and negative values reflecting disproportionately more objective than subjective impairment ('stoicism'). RESULTS More subsyndromal depressive and manic symptoms, hospitalizations, BD type II, and being male positively predicted 'sensitivity', while higher verbal IQ predicted more 'stoicism'. 'Sensitive' patients were characterized by greater socio-occupational difficulties, more perceived stress, and lower quality of life. CONCLUSION Objective neuropsychological assessment seems especially warranted in patients with (residual) mood symptoms, BD type II, chronic illness, and/or high IQ for correct identification of cognitive deficits before commencement of treatments targeting cognition.

Abstract
OBJECTIVE Although many studies showed the negative impact of residual symptoms on the course of bipolar disorder (BD), there is a need to examine potential differences in residual symptoms according to the duration of euthymia in remitted BD patients. METHOD This was a large cross-sectional study of 525 euthymic BD out-patients. A multivariate analysis of covariance was conducted to compare depressive and manic residual symptoms, sleep disturbances and cognitive complaints among three patient groups on the basis of duration of euthymia (A. 6 months to <1 year; B. 1 year to <3 years; C. 3 years to ≤5 years). RESULTS A significant difference between the three groups was found in residual symptoms [Pillai's Trace: F(8942) = 4.659, P < 0.001]. Tukey post hoc analysis indicated that patients from Group C presented lower residual depressive symptoms, higher sleep quality and better perceived cognitive performance compared with Group A. Group B also presented better sleep and cognitive outcomes than Group A. In addition, Group C showed the lowest incidence of functional impairment. CONCLUSION This study suggests that the intensity of residual symptoms and functional impairment in remitted BD patients is negatively related to the duration of euthymia.

Abstract
INTRODUCTION Metacognition, which refers to an individual's ability to assess their own cognitive ability or performance, is poorly understood in bipolar disorder. This study was conducted to evaluate two aspects of metacognitive ability in recently diagnosed patients with bipolar disorder: (a) metacognitive knowledge, pertaining to awareness of one's own general cognitive functioning; and (b) metacognitive experience, referring to awareness of one's cognitive performance on a specific, online cognitive task. METHOD Participants consisted of 50 clinically euthymic patients recently diagnosed with Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV) bipolar I disorder who were within three months of resolution of their first manic episode, and a comparison group of 38 demographically similar healthy volunteers. To assess metacognitive knowledge, participants provided a general rating of their estimated cognitive ability prior to completing a neuropsychological battery, and self-ratings were compared to actual ability based on a composite score of overall cognitive functioning. To assess metacognitive experience, subjects provided a postdiction rating of their perceived memory performance after completing a list learning verbal memory test, and self-ratings were compared to actual memory performance. Measures of both relative and absolute accuracy of ratings were obtained. RESULTS Results indicated that patients showed diminished accuracy in rating their general cognitive ability, implying deficits in metacognitive knowledge. In contrast, patients were accurate in rating their online memory performance, suggesting intact metacognitive experience. CONCLUSIONS Findings suggest that in patients with bipolar disorder, intact task-specific cognitive self-appraisals may fail to generalize to or to modify inaccurate global cognitive self-appraisals. Further research using more comprehensive metacognitive tasks is warranted in bipolar disorder.

Abstract
OBJECTIVES The aims of the present study were to confirm the impact of residual symptoms on overall functioning in a large sample of euthymic patients with bipolar disorder in real-life conditions and to explore the relationship between residual symptoms and specific areas of functional impairment. METHODS This was a multicenter, cross-sectional, non-interventional study of euthymic outpatients with bipolar disorder. The Functioning Assessment Short Test was used to assess overall and specific domains of functioning (autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relationships, and leisure time). Various residual symptoms were assessed (residual mood symptoms, emotional dysregulation, sleep and sexual disorders, stigma, and perceived cognitive impairment). Logistic regression was used to determine the best model of association between functional domains and residual symptoms. RESULTS Almost half of the 468 patients included (42%) had poor overall functioning. Residual depressive symptoms appeared to have an impact on overall functioning and in nearly all areas of functioning. In addition, specific residual symptoms had significantly more negative effects on some domains of functioning in euthymic patients with bipolar disorder (residual manic symptoms and occupational stigma on autonomy, emotional inhibition on occupational functioning, residual manic symptoms on financial issues, family stigma on interpersonal relationships, and sexual function and occupational stigma on leisure time). CONCLUSIONS Our findings highlight the importance of evaluating overall functioning in clinical practice as well as functional domains. They also indicate that some residuals symptoms in patients with bipolar disorder should be targeted in personalized treatment plans, in order to improve functioning in the domains in which the patient is most impaired.

Abstract
INTRODUCTION Cognitive impairment is common in bipolar disorder and contributes to socio-occupational difficulties. The objective was to validate and evaluate instruments to screen for and monitor cognitive impairments, and improve the understanding of the association between cognitive measures and socio-occupational capacity. METHODS Patients with bipolar disorder in partial or full remission (n=84) and healthy controls (n=68) were assessed with the Screen for Cognitive Impairment in Psychiatry (SCIP), Cognitive Complaints in Bipolar Disorder Rating Scale (COBRA), and established neuropsychological tests and subjective rating scales. Socio-occupational function and affective symptoms were evaluated with the Functional Assessment Short Test, and the Hamilton Depression Rating Scale 17-items and Young Mania Rating Scale, respectively. Concurrent validity of the SCIP and COBRA were assessed by correlation with established objective and subjective cognitive measures, and decision validity was determined with Receiver-Operating-Characteristic analyses. Correlations and linear regression analyses were conducted to determine the associations between objective and subjective cognitive impairment, and socio-occupational difficulties. RESULTS The SCIP and COBRA correlated strongly with established objective and subjective cognitive measures, respectively. The SCIP yielded higher sensitivity and specificity for detection of cognitive dysfunction than the COBRA or a combined SCIP-COBRA measure. Correlations between objective and subjective cognitive impairment were weak but both were associated with socio-occupational difficulties. LIMITATIONS Influence of ageing was not investigated. CONCLUSIONS The SCIP and COBRA are valid for detection of objective and subjective cognitive impairment in bipolar disorder. Screening for cognitive dysfunction should be conducted with an objective measure like the SCIP.

Abstract
Cognitive dysfunction is prevalent in bipolar disorder (BD). However, the evidence regarding the association between subjective cognitive complaints, objective cognitive performance and psychosocial function is sparse and inconsistent. Seventy seven patients with bipolar disorder who presented cognitive complaints underwent assessment of objective and subjective cognitive function and psychosocial functioning as part of their participation in two clinical trials. We investigated the association between global and domain-specific objective and subjective cognitive function and between global cognitive function and psychosocial function. We also identified clinical variables that predicted objective and subjective cognitive function and psychosocial functioning. There was a correlation between global subjective and objective measures of cognitive dysfunction but not within the individual cognitive domains. However, the correlation was weak, suggesting that cognitive complaints are not an assay of cognition per se. Self-rated psychosocial difficulties were associated with subjective (but not objective) cognitive impairment and both subjective cognitive and psychosocial difficulties were predicted by depressive symptoms. Our findings indicate that adequate assessment of cognition in the clinical treatment of BD and in drug trials targeting cognition requires implementation of not only subjective measures but also of objective neuropsychological tests.

Abstract
The science of Human Factors and Ergonomics (HF/E) often relies on self-report. This is a cause for concern because subjective methods are inherently susceptible to bias. Here, we present, examine and discuss a puzzling association between age and self-reported cognitive failures as assessed with Broadbent's Cognitive Failures Questionnaire (CFQ). Despite many well-established age-associated forms of cognitive decline, older persons actually report almost equivalent, or even less, cognitive failures on the CFQ than younger persons. Our present analysis indicates that this paradox may be resolved through the fact that people show age-related learning/adaptation/compensation and by the observation that the CFQ measures peoples' beliefs with respect to an individually idiosyncratic reference. Yet, at the heart of the paradox may be the idea that people cannot remember their own cognitive failures, pointing to even greater concerns with all forms of subjective self-report and its use in HF/E. Practitioner Summary: Scientists and practitioners often try to understand and improve human performance with the help of self-report questionnaires. Our paper discusses the validity of self-reported errors measured with the Cognitive Failures Questionnaire (CFQ). We look to resolve the curious paradox that older persons tend to report fewer failures than younger persons do.

Abstract
BACKGROUND Studies in cancer and noncancer populations demonstrate lower than expected correlations between subjective cognitive symptoms and cognitive functioning as determined by standardized neuropsychological tests. This paper systematically examines the association between subjective and objective cognitive functioning in patients with low-grade glioma and the associations of these indicators of cognitive function with clusters of sociodemographic, clinical, and self-reported physical and mental health factors. METHODS Multiple regression analyses with the subjective and 2 objective indicators of cognitive functioning as dependent variables and 4 clusters of predictor variables were conducted in 169 patients with predominantly low-grade glioma. RESULTS Correlations between the subjective and the 2 objective cognitive indicators were negligible (0.04) to low (0.24). Objective cognitive deficits were predominantly associated with sociodemographic (older age, lower education, male sex) and clinical (left hemisphere tumor) variables, while lower ratings of subjective cognitive function were more closely related to self-reported mental health symptoms (fatigue, lower mental well-being), physical (motor) dysfunction and female sex. Self-reported communication deficits were associated significantly with both subjective and objective dysfunction. CONCLUSIONS We recommend that both subjective and objective measures of cognitive functioning, together with a measure of psychological distress, be used for comprehensive neuropsychological assessments of patients with glioma to determine which areas are most affected and which specific intervention strategies are most appropriate.

Abstract
BACKGROUND There is no specific instrument available to measure cognitive deficits as reported by bipolar patients in China. Therefore, if discrepancies between bipolar patients' reports and the results of neuropsychological tests which have been described in other countries existing or not in Chinese bipolar disorder patients have not been known yet. And it is completely blank about the subjective cognition of these Chinese bipolar patients. OBJECTIVES The aim of the study is to revise and validate a specific, user-friendly, brief instrument named the "cognitive complaints in bipolar disorder rating assessment" (COBRA) into Chinese version. METHODS The total sample (N=255) included 125 bipolar disorder patients and 130 healthy controls. The psychometric properties of the COBRA (e.g. internal consistency, retest reliability, discriminative validity, concurrent validity, content validity, item analysis, confirmatory factor analysis, ROC curve and feasibility) were analyzed. RESULTS The Chinese version of the COBRA had very high internal consistency (Cronbach's alpha=0.905) and retest reliability (ICC=0.902). Confirmatory factor analysis validated the one-factor model and the cut-off value to discriminate the patients and controls was 11.Bipolar patients experienced greater cognitive complaints compared to control group suggesting a discriminative validity of the instrument. No significant correlation was found between the COBRA and the total Montreal Cognitive Assessment Scale (MoCA), except for single measures related to executive function (phonemic fluency, p=0.045), verbal memory (delayed recall, p=0.004). LIMITATIONS Cross-sectional design, no specific or unspecific but reliable instrument in Chinese to assess subjective cognitive difficulties in mental disorders for criterion validity or convergent validity analysis. CONCLUSIONS The Chinese version of the COBRA showed to be a simple and reliable instrument to assess subjective cognitive complaints in Chinese bipolar patients.

Abstract
BACKGROUND During the last decades, there have been many different opinions concerning the neurocognitive function in Bipolar disorder (BD). The aim of the current study was to perform a systematic review of the literature and to synthesize the data in a comprehensive picture of the neurocognitive dysfunction in BD. METHODS Papers were located with searches in PubMed/MEDLINE, through June 1st 2015. The review followed a modified version of the recommendations of the Preferred Items for Reporting of Systematic Reviews and Meta-Analyses statement. RESULTS The initial search returned 110,403 papers. After the deletion of duplicates, 11,771 papers remained for further evaluation. Eventually, 250 were included in the analysis. CONCLUSION The current review supports the presence of a neurocognitive deficit in BD, in almost all neurocognitive domains. This deficit is qualitative similar to that observed in schizophrenia but it is less severe. There are no differences between BD subtypes. Its origin is unclear. It seems it is an enduring component and represents a core primary characteristic of the illness, rather than being secondary to the mood state or medication. This core deficit is confounded (either increased or attenuated) by the disease phase, specific personal characteristics of the patients (age, gender, education, etc.), current symptomatology and its treatment (especially psychotic features) and long-term course and long-term exposure to medication, psychiatric and somatic comorbidity and alcohol and/or substance abuse.

Abstract
OBJECTIVE Whether subjective cognitive complaints are suggestive of depression or concurrent cognitive impairment in older adults without dementia remains unclear. The current study examined this question in a large (N = 1000), randomly selected, community-based sample of adults aged 51 to 99 years without a formal diagnosis of dementia (Successful AGing Evaluation [SAGE] study). METHODS The modified Telephone Interview for Cognitive Status (TICS-m) measured objective cognitive function, the Cognitive Failures Questionnaire (CFQ) measured subjective cognitive complaints, and the 9-item Patient Health Questionnaire (PHQ-9) measured depression. Spearman ρ correlations and linear regression models were conducted to examine the relationship among variables in the baseline SAGE sample. RESULTS There was a weak association between TICS-m and CFQ scores (ρ = -.12); however, a moderate to large association was observed for CFQ and PHQ-9 (ρ = .44). Scores on the CFQ were not associated with TICS-m scores (β = -.03, P = .42) after controlling for PHQ-9 and variables of interest, such as age, gender, ethnicity, and physical functioning, while PHQ-9 was significantly associated with CFQ scores (β = .46, P < .001) after controlling for variables of interest. CONCLUSIONS Subjective cognitive complaints are more likely related to symptoms of depression rather than concurrent cognitive impairment in a large cross-section of community-dwelling adults without a formal diagnosis of dementia.

Validity and reliability of a rating scale on subjective cognitive deficits in bipolar disorder (COBRA). J Affect Disord 2013; 150:29-36. [PMID: 23497792 DOI: 10.1016/j.jad.2013.02.022] [Citation(s) in RCA: 109] [Impact Index Per Article: 9.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2012] [Revised: 02/07/2013] [Accepted: 02/07/2013] [Indexed: 11/28/2022]
Abstract
BACKGROUND Discrepancies between bipolar patients' reports and neuropsychological testing have been described and replicated. Unfortunately, no valid, specific, user-friendly, brief instrument is available to measure cognitive deficits as reported by these patients. The main aim of this study was to validate a novel instrument named the "cognitive complaints in bipolar disorder rating assessment" (COBRA). Second, we investigated the relationship between the COBRA, objective cognitive measures and illness course variables. METHOD The total sample (N=215) included 91 bipolar disorder patients and 124 healthy controls. The psychometric properties of the COBRA (e.g. internal consistency, concurrent validity, discriminative validity, factorial analyses, ROC curve and feasibility) were analyzed. A complete neuropsychological battery was used as objective cognitive assessment. RESULTS The COBRA had one-factor structure with very high internal consistency (Cronbach's alpha=0.913). A high convergent validity was indicated by a strong correlation with the Frankfurt Complaint Questionnaire (ro=0.888, p<0.001). Bipolar patients experienced greater cognitive complaints compared to control group suggesting a discriminative validity of the instrument. Significant correlations were found between the COBRA and some objective cognitive measures. Furthermore, higher COBRA scores were associated with bipolar II subtype, residual depressive symptoms, hypomanic episodes and total episodes. LIMITATIONS The cross-sectional design of the study, the influence of medication and severity of patients included. CONCLUSIONS The COBRA showed to be a useful instrument to assess overall cognitive complaints in bipolar disorder with very satisfactory psychometric properties. Cognitive complaints were partially correlated with memory and executive function measures and with issues that may increase the subjective perception of cognitive deficits, such as subthreshold depressive symptoms and number of episodes.

Abstract
BACKGROUND Patients with affective disorders experience cognitive dysfunction in addition to their affective symptoms. The relationship between subjectively experienced and objectively measured cognitive function is controversial with several studies reporting no correlation between subjective and objective deficits. AIMS To investigate whether there is a correlation between subjectively reported and objectively measured cognitive function in patients with affective disorders, and whether subjective complaints predict objectively measured dysfunction. METHODS The study included 45 participants; 15 with bipolar disorder (BD), 15 with unipolar disorder (UD) and 15 healthy individuals. Participants' subjectively experienced cognitive function and objective cognitive function were assessed with the Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire (CPFQ) and the Screen for Cognitive Impairment in Psychiatry (SCIP), respectively. Patients were rated for affective symptoms with Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS). RESULTS Patients demonstrated subjective and objective cognitive dysfunction relative to controls (P-values ≤ 0.01) but there were no differences between patient groups (P > 0.1). We found no correlation between subjectively experienced and objectively measured cognitive dysfunction in BD (P = 0.7), and a non-significant trend towards a correlation in UD (P = 0.06), which disappeared when controlling for gender (P = 0.1). CONCLUSION Our results suggest that it is not necessarily patients who have cognitive complaints that are most impaired. If confirmed in a larger sample, our findings suggest that neuropsychological assessment is warranted to elucidate the potential role of cognitive dysfunction in patients' everyday lives and to inform treatment strategies targeting these difficulties.
