Abstract
Purpose To validate the five-item version of the Perceived Deficits Questionnaire for Depression (PDQ-D-5) for assessing subjective cognitive function in Japanese patients with major depressive disorder (MDD) using data from the PERFORM-J study. Patients and Methods A total of 518 Japanese outpatients diagnosed with MDD were assessed on severity of depressive symptoms, cognitive function, social and work function, and quality of life (QoL) over 6 months following initiation of antidepressant therapy. This post hoc analysis evaluated the internal consistency and convergent validity of the PDQ-D-5 in relation to the original PDQ-D-20. Correlations of scores on these measures were examined at each time point and over time. The same set of analyses was explored between PDQ-D-5 and the Patient Health Questionnaire-nine-item (PHQ-9), Montgomery-Asberg Depression Rating Scale (MADRS), Digit Symbol Substitution Test (DSST), five-level version of EQ-5D (EQ-5D-5L), Sheehan Disability Scale (SDS), and Work Productivity and Activity Impairment (WPAI) questionnaire. Results PDQ-D-5 scores showed good internal consistency. Strong positive correlations were observed between PDQ-D-5 and PDQ-D-20 at each time point (correlation coefficient: baseline, 0.94; month 1, 0.94; month 2, 0.96; month 6, 0.96) and over time (0.92) (all p < 0.0001). Longitudinally, there were positive correlations between PDQ-D-5 scores versus those on the PHQ-9, MADRS, and SDS. Similarly, negative correlations were noted between PDQ-D-5 scores and EQ-5D-5L and DSST scores to a variable degree. There were moderate positive correlations over time between PDQ-D-5 and all WPAI subscale scores except those on absenteeism. Conclusion PDQ-D-5 scores rated in Japanese patients with MDD were found to adequately represent scores on the PDQ-D-20. The short version also showed associations with several measures of functional outcome, depression severity and QoL. This validates the PDQ-D-5 as a feasible and clinically reliable tool to assess subjective experience on cognition, which is applicable to time-limited consultations.

In pursuit of full recovery in major depressive disorder. Eur Arch Psychiatry Clin Neurosci 2022:10.1007/s00406-022-01487-5. [PMID: 36085532 DOI: 10.1007/s00406-022-01487-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Accepted: 08/29/2022] [Indexed: 11/03/2022]
Abstract
Many individuals with major depression disorder (MDD) who achieve remission of depressive symptoms, do not perceive themselves as fully recovered. This study explores whether clinical remission is related to functional remission and to patient's perception of recovery, as well as, which factors are associated with their functional and subjective remission. 148 patients with MDD in partial clinical remission were included. Demographics and clinical variables were collected through semi-structured interviews. Objective cognition was evaluated through a neuropsychological battery and subjective cognition through a specific questionnaire. The patient's psychosocial functioning and the perception of their remission were also assessed. Apart from descriptive analysis, Pearson correlations and backward stepwise regression models explored the relationship between demographic, clinical, and cognitive factors with patients' functional and self-perceived remission. From the whole sample, 57 patients (38.5%) were considered to achieve full clinical remission, 38 patients (25.7%) showed functional remission, and 55 patients (37.2%) perceived themselves as remitted. Depressive symptoms and objective and subjective executive function were the factors associated with psychosocial functioning. Besides, depressive symptoms, objective and subjective attention, and subjective executive function were the significant explanatory variables for self-perception of remission. The concept of full recovery from an episode of MDD should not only include the clinician's perspective but also the patient's psychosocial functioning along with their self-perceived remission. As residual depressive symptoms and cognition (objective and subjective) are factors with great contribution to a full recovery, clinicians should specifically address them when choosing therapeutic strategies.

Abstract
Subjective cognitive decline (SCD) is considered the first stage of Alzheimer's disease (AD). Accurate diagnosis and the exploration of the pathological mechanism of SCD are extremely valuable for targeted AD prevention. However, there is little knowledge of the specific altered morphological network patterns in SCD individuals. In this present study, 36 SCD cases and 34 paired-matched normal controls (NCs) were recruited. The Jensen-Shannon distance-based similarity (JSS) method was implemented to construct and derive the attributes of multiple brain connectomes (i.e., morphological brain connections and global and nodal graph metrics) of individual morphological brain networks. A t-test was used to discriminate between the selected nodal graph metrics, while the leave-one-out cross-validation (LOOCV) was used to obtain consensus connections. Comparisons were performed to explore the altered patterns of connectome features. Further, the multiple kernel support vector machine (MK-SVM) was used for combining brain connectomes and differentiating SCD from NCs. We showed that the consensus connections and nodal graph metrics with the most discriminative ability were mostly found in the frontal, limbic, and parietal lobes, corresponding to the default mode network (DMN) and frontoparietal task control (FTC) network. Altered pattern analysis demonstrated that SCD cases had a tendency for modularity and local efficiency enhancement. Additionally, using the MK-SVM to combine the features of multiple brain connectomes was associated with optimal classification performance [area under the curve (AUC): 0.9510, sensitivity: 97.22%, specificity: 85.29%, and accuracy: 91.43%]. Therefore, our study highlighted the combination of multiple connectome attributes based on morphological brain networks and offered a valuable method for distinguishing SCD individuals from NCs. Moreover, the altered patterns of multidimensional connectome attributes provided a promising insight into the neuroimaging mechanism and early intervention in SCD subjects.

Abstract
BACKGROUND Subanesthetic ketamine infusions can elicit rapid and sustained antidepressant effects, yet the potential cognitive impact of ketamine has not been thoroughly examined. This study measured changes in objective and subjective cognitive function following repeated ketamine treatment. METHODS Thirty-eight patients with treatment-resistant depression were administered cognitive assessments before and after undergoing 7 i.v. ketamine infusions (0.5 mg/kg over 40 minutes) within a clinical trial examining the efficacy of single and repeated administrations. Depression severity and perceived concentration were evaluated with the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Quick Inventory of Depressive Symptoms Self-Report. RESULTS Twenty-three participants (60.5%) responded after repeated infusions (≥50% decrease in MADRS total scores). We measured significant improvements in several cognitive domains, including attention, working memory, verbal, and visuospatial memory (effect sizes ranging from Cohen d = 0.37-0.79). Cognitive changes were attributed to reduction in depressive symptoms except for improvement in verbal memory, which remained significant after adjustment for change in MADRS total score (P = .029, η p2 = 0.13). Only responders reported improvement in subjective cognitive function with repeated ketamine administration (MADRS item 6, P < .001, d = 2.00; Quick Inventory of Depressive Symptoms Self-Report item 10, P < .001, d = 1.36). CONCLUSION A short course of repeated ketamine infusions did not impair neurocognitive function in patients with treatment-resistant depression. Further research is required to understand the potential mediating role of response and remission on improved cognitive function accompanying ketamine treatment as well as to examine longer-term safety outcomes.

Abstract
OBJECTIVE This study aimed to compare the efficacy and safety of escitalopram, vortioxetine, and desvenlafaxine for acute treatment of major depressive disorder (MDD) with cognitive complaint (CC). METHODS A total of 129 patients with MDD who also complained of CC were randomized evenly to either escitalopram, vortioxetine, or desvenlafaxine group and underwent a multi-center, six-week, rater-blinded, and head-to-head comparative trial. Differences in depressive symptoms following treatment were measured using the Hamilton Depression Rating Scale (HAMD) and the Montgomery-Åsberg Depression Rating Scale (MADRS). Subjective cognitive function and the presence of adverse events were assessed. RESULTS The three antidepressant treatment groups did not show significant differences in the improvement of depressive symptoms as measured by HAMD and MADRS. Desvenlafaxine treatment was associated with a superior treatment response rate in depressive symptoms compared to vortioxetine or escitalopram treatment. However, no significant differences were found in the remission rate of depressive symptoms. The three antidepressant treatment groups did not show significant differences in the improvement of CC. Adverse profiles of each treatment group were tolerable, with no significant differences. CONCLUSION In acute antidepressant treatment for MDD with CC, escitalopram, vortioxetine, and desvenlafaxine presented similar efficacy in relief of depressive symptoms; however, desvenlafaxine was associated with a superior treatment. Further studies are needed to confirm these results by investigating the therapeutic efficacy and safety profile of long-term antidepressant treatment of MDD with CC (Clinical Trial Registry, http://cris.nih.go.kr/cris/en/: KCT0002173).

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.

Prediction of residual cognitive disturbances by early response of depressive symptoms to antidepressant treatments in patients with major depressive disorder. J Affect Disord 2022; 296:95-102.

Abstract
BACKGROUND Patients with major depressive disorder (MDD) frequently retain cognitive disturbances after recovery from mood symptoms. We investigated the relationship between early response of mood symptoms and/or remission, and residual cognitive disturbances after 6 months of antidepressant treatment. METHODS 518 patients with MDD were followed up for 6 months after antidepressant treatment initiation (first-line or switch from a previous drug). Subjective and objective cognitive disturbances were assessed by the Perceived Deficits Questionnaire - Depression (PDQ-D) and digit symbol substitution test (DSST), respectively. Depressive symptoms, as well as remission and early response to treatment, were assessed using the Montgomery-Asberg Depression Rating Scale (MADRS). Multivariable linear and logistic regression models were used to adjust for confounders. RESULTS Early response of depressive mood (≥50% reduction in MADRS score at month 1) was related with fewer residual subjective cognitive symptoms, as evaluated by the PDQ-D at month 6 (p<0.001). Likewise, early remission status at month 2 was inversely associated with PDQ-D scores at month 6 (p<0.001). Among patients with baseline DSST scores of ≥1 standard deviation below the norm, early response/remission was associated with better performance on the DSST at month 6 (p<0.05). LIMITATIONS The cohort may not be representative of the general MDD patient population, and the possible influence of concomitant medications was not evaluated. CONCLUSIONS These findings suggest that early improvements in depressive symptoms predict better cognitive outcomes in patients with MDD. Grouping of patients by mood and cognition status in early stages of antidepressant treatments may facilitate efforts to improve long-term functional outcomes.

Abstract
BACKGROUND Early symptomatic improvement with monoamine-based antidepressants is predictive of treatment response. The objective of this study was to determine if early symptomatic improvements with intravenous (IV) ketamine predicted treatment response to an acute course of four infusions. METHOD 134 adults with treatment resistant depression (TRD) received four ketamine infusions over one to two weeks. Depressive symptoms were measured using the Quick Inventory for Depressive Symptomatology Self-Report16 (QIDS-SR16) at baseline and post-infusions 1, 2, 3, and 4. Early improvement was defined as ≥20% reduction in QIDS-SR16 scores after the first or second infusion. Linear models were used to determine whether early improvement was associated with post-infusion 4 QIDS-SR16 scores after controlling for baseline characteristics. RESULTS Early improvement post-infusion 1 (β = -3.52, 95% BCa CI [-5.40, -1.78]) and 2 (β = -3.16, 95% BCa CI [-5.75, -1.59]) both significantly predicted QIDS-SR16 scores post-infusion 4. Early improvers had significantly lower QIDS-SR16 scores at post-infusion 4 (post-infusion 1 improvers: M = 9.8, SD = 4.5; post-infusion 2 improvers: M = 10.6, SD = 5.7) compared to non-early improvers (post-infusion 1 non-improvers: M = 13.7, SD = 5.8; post-infusion 2 non-improvers: M = 14.1, SD = 5.3) when controlling for baseline characteristics. The majority (58%) of individuals who did not improve post-infusions 1 or 2 still experienced an antidepressant response or partial response (≥20% reduction in QIDS-SR16) post-infusion 4. LIMITATIONS This is a post-hoc analysis of an open-label study. CONCLUSION Early improvement was associated with greater antidepressant effects following a course of four ketamine infusions. However, individuals who did not show early improvements still had a high likelihood of experiencing clinically significant symptom reduction after the fourth infusion, suggesting that completing four infusions, regardless of early symptom changes, is appropriate and merited.

Abstract
Subjective cognitive decline (SCD) is considered the earliest preclinical stage of Alzheimer’s disease (AD) that precedes mild cognitive impairment (MCI). Effective and accurate diagnosis of SCD is crucial for early detection of and timely intervention in AD. In this study, brain functional connectome (i.e., functional connections and graph theory metrics) based on the resting-state functional magnetic resonance imaging (rs-fMRI) provided multiple information about brain networks and has been used to distinguish individuals with SCD from normal controls (NCs). The consensus connections and the discriminative nodal graph metrics selected by group least absolute shrinkage and selection operator (LASSO) mainly distributed in the prefrontal and frontal cortices and the subcortical regions corresponded to default mode network (DMN) and frontoparietal task control network. Nodal efficiency and nodal shortest path showed the most significant discriminative ability among the selected nodal graph metrics. Furthermore, the comparison results of topological attributes suggested that the brain network integration function was weakened and network segregation function was enhanced in SCD patients. Moreover, the combination of brain connectome information based on multiple kernel-support vector machine (MK-SVM) achieved the best classification performance with 83.33% accuracy, 90.00% sensitivity, and an area under the curve (AUC) of 0.927. The findings of this study provided a new perspective to combine machine learning methods with exploration of brain pathophysiological mechanisms in SCD and offered potential neuroimaging biomarkers for diagnosis of early-stage AD.

Abstract
Cognitive impairments in depression contribute to disability. According to prevailing cognitive theories, one's perception related to cognitive ability can cause and maintain depression, and related outcomes. Here, we investigate the degree to which perceived cognitive impairment predicts functional impairment above and beyond objective neurocognition. A sample of young adults (n = 123) completed a battery of tests measuring objective cognitive ability, perceived cognitive function (e.g., Perceived Deficits Questionnaire), disability (e.g., World Health Organization Disability Assessment Schedule) and depressive symptoms (Beck Depression Inventory-2). Hierarchical multiple regression analyses tested the incremental variance that perceived cognitive impairment accounts for above and beyond neuropsychological test measures and disability related to depression. Results show that perceived cognitive impairment accounts for significant incremental variance in depressive symptoms beyond neuropsychological test scores; disability measures were significantly associated with depressive symptoms, as was perceived cognitive impairment. Individuals with depression and related disorders are more likely to report cognitive impairments and experience diminished cognitive ability - relative to healthy controls - regardless of objective impairments, highlighting the importance of considering, measuring, and treating this perceived cognitive impairment, that is, Cognitive Impairment Bias (Dhillon and Zakzanis, 2019).
