In light of Rational-Emotive Theory, this study was undertaken to determine the pattern of irrational beliefs underlying Major Depressive Disorder (MDD). A total of 126 subjects (50 males, 76 females) volunteered to participate. Patients clinically diagnosed with MDD (unipolar type) and a control group of non-depressed patients were solicited from the inpatient and outpatient facilities of several Ottawa and Montreal hospitals; the normal control group comprised students and civil servants. The subjects completed questionnaires to measure irrational belief endorsement (IBT, RBI) and symptom severity (STAI, BDI) and to verify the depression diganosis (IDD). Multivariate statistics were used to determine the pattern of beliefs which best discriminates between the MDD group, the psychiatric control group, and the normal controls. Discriminant analysis of the IBT revealed a pattern of four irrational beliefs generally known as demand for approval, frustration reactivity, anxious overconcern, and helplessness over past. The implications of such findings for RET theory are discussed.

Objective: Improving future thinking may be one means to reduce anhedonia, particularly in Major Depressive Disorder (MDD) in which future thinking is impaired. The current study therefore examined whether enhancing future thinking is a viable method of reducing anhedonia in MDD. Methods: Participants (N=177; 80.8% women; M age=43.7, SD=11.8) with a current depressive episode including anhedonia and high symptom severity were randomized to a Future Event Specificity Training (FEST) program or wait-list control. Future thinking characteristics, anhedonia-related variables, and other clinical outcomes were assessed at baseline, one- and three-month follow-up. Results: The FEST group showed significantly improved future thinking characteristics compared to the control group, as expected. Relative to the control group, FEST was also associated with a reduced likelihood of anhedonia (35.1% vs 61.1%, p = .015), improvements on other anhedonia-related variables such as anticipatory (d = 0.63, p = .004) and anticipated pleasure (d = 0.77, p < .001), and desirable clinical outcomes such as less people meeting criteria for MDD (37.8% vs 64.8%, p = .011), lower symptom severity (d = 0.41, p = .048), higher behavioural activation (d = 0.71, p = .001) and improved global functioning (d = 0.52, p = .017). Changes in future thinking characteristics were found to mediate the effect of FEST on anhedonia.Conclusions: Future thinking can be enhanced in MDD, and this leads to a substantially reduced likelihood of anhedonia, other significant clinical effects and functional gains. Future research might examine FEST’s effects on other diagnostic groups with anhedonia and the utility of FEST as an adjunct to other treatments.

The Relationship

BackgroundWhite matter abnormalities have been implicated in the aetiology of major depressive disorder; however, the relationship between the severity of symptoms and white matter integrity is currently unclear.AimsTo investigate white matter integrity in people with major depression and healthy controls, and to assess its relationship with depressive symptom severity.MethodDiffusion tensor imaging data were acquired from 66 patients with recurrent major depression and a control group of 66 healthy individuals matched for age, gender and IQ score, and analysed with tract-based spatial statistics. The relationship between white matter integrity and severity of depression as measured by the Beck Depression Inventory was examined.ResultsDepressive illness was associated with widespread regions of decreased white matter integrity, including regions in the corpus callosum, superior longitudinal fasciculus and anterior corona radiata, compared with the control group. Increasing symptom severity was negatively correlated with white matter integrity, predominantly in the corpus callosum.ConclusionsWidespread alterations in white matter integrity are evident in major depressive disorder. These abnormalities are heightened with increasing severity of depressive symptoms.

The Impact

Objectives: Major depressive disorder (MDD) is associated with impairments in both cognition and functioning. However, whether cognitive deficits significantly contribute to impaired psychosocial and occupational functioning, independent of other depressive symptoms, is not well established. We examined the relationship between cognitive performance and functioning in depressed patients before and after antidepressant treatment using secondary data from the first Canadian Biomarker Integration Network in Depression-1 study. Methods: Cognition was assessed at baseline in unmedicated, depressed participants with MDD ( n = 207) using the Central Nervous System Vital Signs computerized battery, psychosocial functioning with the Sheehan Disability Scale (SDS), and occupational functioning with the Lam Employment Absence and Productivity Scale (LEAPS). Cognition ( n = 181), SDS ( n = 175), and LEAPS ( n = 118) were reassessed after participants received 8 weeks of open-label escitalopram monotherapy. A series of linear regressions were conducted to determine (1) whether cognitive functioning was associated with psychosocial and occupational functioning prior to treatment, after adjusting for overall depressive symptom severity and (2) whether changes in cognitive functioning after an 8-week treatment phase were associated with changes in psychosocial and occupational functioning, after adjusting for changes in overall symptom severity. Results: Baseline global cognitive functioning, after adjusting for depression symptom severity and demographic variables, was associated with the SDS work/study subscale (β = −0.17; P = 0.03) and LEAPS productivity subscale (β = −0.17; P = 0.05), but not SDS total (β = 0.19; P = 0.12) or LEAPS total (β = 0.41; P = 0.17) scores. Although LEAPS and SDS scores showed significant improvements after 8 weeks of treatment ( P < 0.001), there were no significant associations between changes in cognitive domain scores and functional improvements. Conclusion: Cognition was associated with occupational functioning at baseline, but changes in cognition were not associated with psychosocial or occupational functional improvements following escitalopram treatment. We recommend the use of more comprehensive functional assessments to determine the impact of cognitive change on functional outcomes in future research.

Introduction and Objective. Despite the effectiveness of electroconvulsive therapy (ECT) in treating major depressive disorder (MDD), its cognitive side effects make it less popular. This study investigated the impact of liothyronine on ECT-induced memory deficit in patients with MDD.Methodology. This is a double-blind clinical trial, in which 60 patients with MDD who were referred for ECT were selected. The diagnosis was based on the criteria of DSM-IV-TR. Patients were divided randomly into two groups to receive either liothyronine (50 mcg every morning) or placebo. After the assessment with Wechsler Memory Scale-Revised (WMS-R) before first session of ECT, posttests were repeated again, two months after the completion of ECT.Findings. By controlling the pretest scores, the mean scores of the experimental group were higher than the control group in delayed recall, verbal memory, visual memory, general memory, and attention/concentration scales (P<0.05).Conclusion. Liothyronine may prevent ECT-induced memory impairment in patients with MDD. This study has been registered in IRCT underIRCT201401122660N2.

Abstract Background Major depressive disorder (MDD) is a common psychiatric disorder that affects nearly 11.1-14.6 % of the population in their lifetime. Pathophysiology and brain imaging findings show that degenerative and inflammatory processes may play a role. Meta-analysis of voxel-based morphometry studies in MDD demonstrated significant gray matter loss. From anatomical and embryological perspectives, the retina can be considered a unique extension of the brain and is able to reflect axonal histopathology. Being unmyelinated, it can provide insight into the pathophysiological processes of diseases with a neurodegenerative element. Aim to compare retinal optical coherence tomography (OCT) parameters in a group of MDD patients with a healthy control group and to correlate OCT parameters with pattern electroretinography (PERG) parameters. Method a controlled cross sectional study was conducted on 30 MDD patients and 28 age and sex matched controls. Both groups had a full ophthalmological examination, OCT imaging and 7 patients and 11 controls have PERG recorded. Results Thinning of the superior retinal nerve fiber layer, thinning of most of the ganglion cell inner plexiform (GCIP) layer, thinning of most of the macular thickness and thinning of macular volume in both eyes were detected. There was a statistically significant positive correlation between the left GCIP layer and the amplitude of the N95 wave. Also a statistically significant negative correlation existed between MDD duration in years with the left eye's average volume of the outer ring of the macula. Conclusion Significant retinal changes were detected by OCT in MDD patients supporting the theory of neurodegeneration as a pathophysiology of MDD.

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.

SummaryThe prevalence of an abnormal response to the dexamethasone suppression test (DST) was examined in 119 in-patients suffering from a major depressive disorder and in 79 normal controls. Only 11 per cent of controls showed an abnormal DST as against 70 per cent of depressed patients. The specificity of the DST was examined by testing patients with other psychiatric disorders. Abnormal responses were found in one-fifth of a sample of schizophrenics, over one-quarter of abstinent alcoholics, two-fifths of neurotics (including neurotic depressives) and almost half of senile dements. Abnormal DST was also found in 33 per cent of patients receiving prophylactic lithium for recurrent affective disorders.

Introduction: Major depressive disorder (MDD) is a common affective disorder. Currently established pharmacotherapies lack rapid clinical response, thereby limiting their ability to bring instant relief to patients. A series of clinical trials has demonstrated the antidepressant effects of scopolamine, yet few have studied the effects of add-on scopolamine to currently available antidepressants. It is not known whether conventional antidepressant treatment with a 3-day scopolamine injection could speed up oral antidepressant efficacy. The main focus of this study is to detect the capacity of the rapid-onset efficacy of such a treatment option. Methods and analysis: This study consisted of a single-centre, double-blind, three-arm randomized trial with a 4-week follow-up period. Sixty-six participants meeting entry criteria were randomly allocated to three treatment groups: a high-dose group, a low-dose group and a placebo control group. Psychiatric rating scales were administered at baseline and seven viewing points following the administration of intramuscular injections. The primary outcome measure was length of time from randomization (baseline) to early improvement. Results: Both primary and secondary outcome measures consistently showed no differences among the three groups. The cumulative response rate and the remission rate were 72.7% (48/66) and 47.0% (31/66). Intramuscular scopolamine treatment was relatively well tolerated. Two subjects with high-dose injections dropped out because of a drug-related side effect. Conclusion: Contrary to our prediction, we found that, compared to placebo (0.9% saline i.m.), scopolamine was not associated with a significantly faster antidepressant response rate. Trial registration: ClinicalTrials.gov, NCT03131050. Registered on 18 April 2017.

ObjectivesTo examine employment and earnings trajectories before and after the first sickness absence period due to major depressive disorder (MDD).MethodsAll individuals (n=158 813) in Finland who had a first sickness absence period (lasting longer than 9 days) due to MDD between 2005 and 2015 were matched with one randomly selected individual of the same age and gender with no history of MDD. Employment status and earnings were measured using register-based data annually from 2005 to 2015. Generalised estimating equations were used to examine the trajectories of employment and earnings before and after MDD diagnosis in men and women separately.ResultsSickness absence due to MDD was associated with increased probability of non-employment during and after the year of the first sickness absence period. In men, but not in women, the probability of being employed was lower 5 years before the sickness absence period due to MDD. When compared with the individuals in the control group, men had around 34% and women 15% lower earnings 1 year, and 40% and 23%, respectively, 5 years, after the first sickness absence period due to MDD. More severe MDD and longer duration of sickness absence period were associated with lower probability of being employed.ConclusionsSickness absence due to MDD was associated with considerable reduction in employment and earnings losses. For men and individuals with more severe MDD, this reduction was before the first sickness period. This supports a reciprocal association between employment and earnings with MDD.
