BackgroundCognitive dysfunction is common in major depressive disorder (MDD) and a critical determinant of health outcome. Anhedonia is a criterion item toward the diagnosis of a major depressive episode (MDE) and a well-characterized domain in MDD. We sought to determine the extent to which variability in self-reported cognitive function correlates with anhedonia.MethodA post hoc analysis was conducted using data from (N=369) participants with a Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR)-defined diagnosis of MDD who were enrolled in the International Mood Disorders Collaborative Project (IMDCP) between January 2008 and July 2013. The IMDCP is a collaborative research platform at the Mood Disorders Psychopharmacology Unit, University of Toronto, Toronto, Canada, and the Cleveland Clinic, Cleveland, Ohio. Measures of cognitive function, anhedonia, and depression severity were analyzed using linear regression equations.ResultsA total of 369 adults with DSM-IV-TR–defined MDD were included in this analysis. Self-rated cognitive impairment [ie, as measured by the Adult ADHD Self-Report Scale (ASRS)] was significantly correlated with a proxy measure of anhedonia (r=0.131, p=0.012). Moreover, total depression symptom severity, as measured by the total Montgomery–Åsberg Depression Rating Scale (MADRS) score, was also significantly correlated with self-rated measures of cognitive dysfunction (r=0.147, p=0.005). The association between anhedonia and self-rated cognitive dysfunction remained significant after adjusting for illness severity (r=0.162, p=0.007).ConclusionsThese preliminary results provide empirical data for the testable hypothesis that anhedonia and self-reported cognitive function in MDD are correlated yet dissociable domains. The foregoing observation supports the hypothesis of overlapping yet discrete neurobiological substrates for these domains.

BACKGROUND Cognitive symptoms are common in major depressive disorder, and may help to identify patients that need treatment or who are not experiencing adequate treatment response. Digital tools to provide real time data assessing cognitive function could help to support patients treatment and remediation of cognitive and mood symptoms. OBJECTIVE This study examined adherence, feasibility, and validity of a wearable high-frequency cognitive and mood assessment app over 6 weeks, corresponding to when antidepressant pharmacotherapy begins to show efficacy. METHODS Thirty patients (aged 19−63; 19 women) with mild-moderate depression participated. The new Cognition Kit application was delivered via the Apple Watch, providing a high-resolution touch screen display for task presentation and logging responses. Cognition was assessed by the n-back task up to 3 times daily and depressed mood by 3 short questions once daily. Selected tests sensitive to depression from the Cambridge Neuropsychological Test Automated Battery and validated questionnaires of depression symptom severity were administered on 4 occasions (baseline, weeks 1, 3, and 6). Adherence was defined as participants completing at least one assessment daily. RESULTS Adherence was excellent for mood and cognitive assessments (95% and 96%, respectively), did not deteriorate over time, and was not influenced by depression symptom severity or cognitive function at study onset. Daily mood assessments showed good correspondence with validated depression questionnaires (correlations range from .45 to .69 for total daily mood score) and daily cognitive assessments showed good correspondence with cognitive tests sensitive to depression (correlations ranged from .37 to .50 for mean n-back). CONCLUSIONS The study supports the feasibility and validity of high-frequency assessment of cognitive function and mood function using wearable devices over an extended period in patients with major depressive disorder.

Objective: We sought to determine whether a reported history of childhood adversity is associated with components of the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP-III)-defined metabolic syndrome in adults with mood disorders. Method: This was a cross-sectional analysis of adult outpatients ( n = 373; n = 230 female, n = 143 male; mean age [ SD]=42.86 [14.43]) from the International Mood Disorders Collaborative Project (University of Toronto and Cleveland Clinic) with DSM-IV-defined major depressive disorder and bipolar I/II disorder. Childhood adversity was measured with the Klein Trauma & Abuse-Neglect self-report scale. The groups with and without childhood adversity were compared to determine possible differences in the rates of metabolic syndrome and its components. Logistic and linear regressions adjusted for age, sex, education, employment status, and smoking were used to evaluate the association between childhood adversity and components of metabolic syndrome. Results: For the full sample, 83 subjects (22.25%) met criteria for metabolic syndrome. Individuals reporting a history of any childhood adversity had higher systolic and diastolic blood pressure (systolic: p = 0.040; diastolic: p = 0.038). Among subjects with a history of sexual abuse, a significant proportion met criteria for obesity (45.28% vs. 32.88%; p = 0.010); a trend toward overweight was found for subjects with a history of physical abuse (76.32% vs. 63.33%; p = 0.074), although this relationship did not remain significant after adjusting for potential confounders. There was no statistically significant difference in the overall rate of dyslipidemia and/or metabolic syndrome between subjects with and without childhood adversity. Conclusion: The results herein provide preliminary evidence suggesting that childhood adversity is associated with metabolic syndrome components in individuals with mood disorders.

<b><i>Introduction:</i></b> The hippocampus is relevant to cognitive function in schizophrenia (SCZ) and mood disorder patients. Although not anatomically uniform, it is clearly divided into subfields. This study aimed to elucidate the relationship between hippocampal subfield volume and cognitive function in patients with SCZ, bipolar disorder (BP), and major depressive disorder (MDD). <b><i>Methods:</i></b> The study included 21 patients with SCZ, 22 with BP, and 21 with MDD and 25 healthy controls (HCs). Neurocognitive function was assessed using the Brief Assessment of Cognition in Schizophrenia. We obtained hippocampal subfield volumes using FreeSurfer 6.0. We compared the volumes of the hippocampal subfield between the 4 groups and ascertained correlation between the cognitive composite score and hippocampal subfield volume in each group. <b><i>Results:</i></b> The SCZ group had significantly lower cognitive composite score than the BP, MDD, and HC groups. In the SCZ group, the left and right hippocampus-amygdala transition area and right subiculum and right presubiculum volumes were significantly reduced compared to those in the HC group. The left presubiculum volumes in the SCZ group were significantly reduced compared to those in the MDD group. Subfield volumes did not significantly differ between the BP, MDD, and HC groups. Interestingly, in the SCZ group, volumes of the right CA1, right molecular layer of the hippocampus, and right granule cell and molecular layer of the dentate gyrus were significantly correlated with the cognitive composite score. <b><i>Conclusion:</i></b> Patients with SCZ had poorer cognitive function, which is related to their hippocampal pathology, than those with mood disorders.

Cognitive dysfunction is a symptomatic domain identified across many mental disorders. Cognitive deficits in individuals with major depressive disorder (MDD) contribute significantly to occupational and functional disability. Notably, cognitive subdomains such as learning and memory, executive functioning, processing speed, and attention and concentration are significantly impaired during, and between, episodes in individuals with MDD. Most antidepressants have not been developed and/or evaluated for their ability to directly and independently ameliorate cognitive deficits. Multiple interacting neurobiological mechanisms (eg, neuroinflammation) are implicated as subserving cognitive deficits in MDD. A testable hypothesis, with preliminary support, posits that improving performance across cognitive domains in individuals with MDD may improve psychosocial function, workplace function, quality of life, and other patient-reported outcomes, independent of effects on core mood symptoms. Herein we aim to (1) provide a rationale for prioritizing cognitive deficits as a therapeutic target, (2) briefly discuss the neurobiological substrates subserving cognitive dysfunction, and (3) provide an update on current and future treatment avenues.

IntroductionSeveral studies have explored the vulnerability to mood disorders that constitute some personality traits.AimsTo study the potential relationship between mood disorders and personality disorders.ObjectiveWe hypothesized that personality disorders can be related to severe mood disorders.MethodsThis was a retrospective study including the period from January 2000 till September 2015 and related to patients in whom the diagnosis of mood disorder and personality one were retained according to the criteria of the DSM-IV TR while the sociodemographic and clinical were collected by a pre-established railing.ResultsWe included 28 patients (15 ♂, 13 ♀). The average age was 38 years. Eighteen (64.3%) patients (7 ♂, 11 ♀) are unemployed. Fifteen patients (10 ♂, 5 ♀) were schooled until secondary level. Seventeen patients (60.7%) were married. The bipolar I disorder (BD I) was most frequently founded (50%), followed by the major depressive disorder in 25% (n = 7) then by the bipolar II disorder in 21.4% (n = 6). A case of dysthymia was also noted. Half of the personality disorders were the borderline type, followed by the histrionic type in 28.6% (n = 8) then by the antisocial in 17.9% (n = 5) and finally one patient presented a paranoiac personality. The antisocial personality was significantly associated with the BD I (P = 0.011) and half of the patients with a pathological personality, presented a depressive symptomatology.ConclusionThe personality disruption is a factor of severity of the thymic disorders. Consequences on the management of patients and their response to treatments remain available.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Exploratory analyses examined the relationship between mood and cognitive measures acquired in low- and high-frequency assessment. Results Adherence was excellent for mood and cognitive assessments (95% and 96%, respectively), did not deteriorate over time, and was not influenced by depression symptom severity or cognitive function at study onset. Analyses examining the relationship between high-frequency cognitive and mood assessment and validated measures showed good correspondence. Daily mood assessments correlated moderately with validated depression questionnaires (r=0.45-0.69 for total daily mood score), and daily cognitive assessments correlated moderately with validated cognitive tests sensitive to depression (r=0.37-0.50 for mean n-back). Conclusions This study supports the feasibility and validity of high-frequency assessment of cognition and mood using wearable devices over an extended period in patients with major depressive disorder.

Patient self-report health measures have received increasing recognition as supplementar y outcome parameters in multiple sclerosis (MS). G iven the high prevalence of cognitive problems in this population, reliability and validity of self-report instruments in patient groups with cognitive impairment is essential, especially when using such scales longitudinally. A sample of 80 MS patients with cognitive dysfunction according to Symbol Digit Modalities Test (SDMT) score and 107 unimpaired patients were included in the analyses. Data was available from the Hamburg Q uality of Life Q uestionnaire in Multiple Sclerosis (HAQ UA MS), the Hospital A nxiety and Depression Scale (HA DS), clinical rating scores [Expanded Disability Status Scale (EDSS) and FS (Functio nal Status) scales, C A MBS (Cambridge MS Basic Score)] and objective tests of upper and lower limb function [Timed 8 Meter Walk (T8) and Nine Hole Peg Test (9HPT)). Both self-report questionnaires showed satisfactory internal consistencies and retest reliability. Pattern and magnitude of correlations with other health status measures supported the validity of both instruments. However, there was a marked discrepancy between subjective and objective measures of cognitive function. C ognitively impaired patients furthermore showed significantly higher depression and anxiety as well as lower quality of life (Q oL). The report provides evidence that Q oL and affective symptomatology can be reliably assessed in MS patients with cognitive dysfunction. The common pattern of poor correlation between self-rated and objective cognitive function thus appears to be a result of the patients’ (adaptive or maladaptive) coping mechanisms rather than being due to inaccurate measurement.
