Abstract
Introduction: This study explores using Neural Ordinary Differential Equations (NODEs) to analyze hormone dynamics in the hypothalamicpituitary-adrenal (HPA) axis during Trier Social Stress Tests (TSST) to classify patients with Major Depressive Disorder (MDD). Methods: Data from TSST were used, measuring plasma ACTH and cortisol concentrations. NODE models replicated hormone changes without prior knowledge of the stressor. The derived vector fields from NODEs were input into a Convolutional Neural Network (CNN) for patient classification, validated through cross-validation (CV) procedures. Results: NODE models effectively captured system dynamics, embedding stress effects in the vector fields. The classification procedure yielded promising results, with the 1x1 CV achieving an AUROC score that correctly identified 83% of Atypical MDD patients and 53% of healthy controls. The 2x2 CV produced similar outcomes, supporting model robustness. Discussion: Our results demonstrate the potential of combining NODEs and CNNs to classify patients based on disease state, providing a preliminary step towards further research using the HPA axis stress response as an objective biomarker for MDD.

A case series and literature review. Front Psychiatry 2024; 15:1372136. [PMID: 38571997 PMCID: PMC10987948 DOI: 10.3389/fpsyt.2024.1372136] [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: 01/17/2024] [Accepted: 02/27/2024] [Indexed: 04/05/2024] Open
Abstract
Background Catatonia has been increasingly associated with mood disorders and is recognized as a specifier in the DSM-5 and DSM-5-TR. The DSM-5-TR recognizes melancholia as a specifier for depressive episodes in major depressive disorder and bipolar disorder. It is characterized by severe anhedonia, lack of reactivity, excessive or delusional guilt, and significant vegetative symptoms. As the conceptualization of melancholia expanded beyond its mood components to include psychomotor disturbances, its overlap with psychomotor symptoms or catatonia becomes evident. This overlap was also described in Kahlbaum's original literature, where he describes the transition between states of melancholia, mania, and catatonia. Method Case summary of six patients with major depressive disorder or depressed phase of bipolar disorder who were admitted for severe depression, anhedonia, intense anxiety, psychomotor agitation or retardation, indecisiveness, perseveration, and vegetative symptoms such as poor sleep, appetite, and significant weight loss. Results All patients demonstrated rapid and complete resolution of their mood and psychomotor symptoms, indecisiveness, perseveration, as well as psychosis shortly after administration of lorazepam, with recurrence of the above symptoms upon lorazepam discontinuation and resolution upon resumption, in an on-and-off manner. Conclusion The present study argues for a closer relationship between melancholia and catatonia based on our case series, historical review, overlap in phenomenology, and response to treatment. We propose provisional [Mahgoub] criteria for patients with severe depression and melancholia. The role of GABA agonists, such as lorazepam, can be explored as an option for patients with treatment-resistant depression who meet these criteria for melancholia. Limitations Absence of a standardized, systematic assessment tool and a small sample size.

Abstract
Based on the seminal publications of Paul Broca and Carl Wernicke who established that aphasic syndromes (disorders of the verbal-linguistic aspects of communication) were predominantly the result of focal left-hemisphere lesions, "language" is traditionally viewed as a lateralized function of the left hemisphere. This, in turn, has diminished and delayed the acceptance that the right hemisphere also has a vital role in language, specifically in modulating affective prosody, which is essential for communication competency and psychosocial well-being. Focal lesions of the right hemisphere may result in disorders of affective prosody (aprosodic syndromes) that are functionally and anatomically analogous to the aphasic syndromes that occur following focal left-hemisphere lesions. This paper will review the deductive research published over the last four decades that has elucidated the neurology of affective prosody which, in turn, has led to a more complete and nuanced understanding of the neurology of language, depression, emotions and memory. In addition, the paper will also present the serendipitous clinical observations (inductive research) and fortuitous inter-disciplinary collaborations that were crucial in guiding and developing the deductive research processes that culminated in the concept that primary emotions and related display behaviors are a lateralized function of the right hemisphere and social emotions, and related display behaviors are a lateralized function of the left hemisphere.

Front Psychiatry 2023; 14:1216431. [PMID: 37599865 PMCID: PMC10437052 DOI: 10.3389/fpsyt.2023.1216431] [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: 05/03/2023] [Accepted: 07/10/2023] [Indexed: 08/22/2023] Open
Abstract
Introduction Whether melancholia is a distinct syndrome has long been debated. One aspect of a valid syndrome is whether it allows for determination of a prognosis. The aim of this study is to investigate the course of melancholic depression versus non-melancholic depression with a focus on: (i) time to and probability of recovery from the first depressive episode, (ii) time to and risk of the first recurrence, (iii) rate of recurrence, (iv) time with depression or antidepressant medication, and (v) suicide risk. Methods The Lundby Study is a longitudinal community study on mental health that followed a geographically defined population (N = 3,563) for up to 50 years, 1947-1997. Subjects with first onset depression were assessed as melancholic (N = 46) or non-melancholic (N = 381) using the DSM-IV melancholic specifier. These diagnoses were made in retrospect using all available information from semi-structured interviews by psychiatrists, key informants, registers, and patient records. Results We found no significant difference between melancholic- and non-melancholic depression in time to and probability of recovery from the first depressive episode. The time to first recurrence was shorter in melancholic than in non-melancholic depression and the risk of first recurrence for the melancholic group was 2.77 (95% confidence interval [CI] 1.83-4.20) times the risk in the non-melancholic group. The median rate of recurrence was higher in the melancholic group, at 0.19 recurrences per year at risk (interquartile range [IQR] 0.08-0.47), compared to the non-melancholic group, at 0.10 recurrences per year at risk (IQR 0.05-0.21) (p < 0.03). The median percentage of time being depressed or on antidepressant medication was higher in the melancholic group, 17% (IQR 3-20%), compared to the non-melancholic group, 8% (IQR 7-33%) (p < 0.001). The risk of suicide was higher in the melancholic group, hazard ratio 4.13 (95% CI 1.49-11.48, p < 0.01). Discussion To conclude, melancholic depression had a more recurrent, chronic, and severe course with a higher suicide risk than did non-melancholic depression in the Lundby population. Although our use of retrospective diagnosis might limit interpretation of results, the findings indicate that melancholia may be useful in determining prognosis and may be a valid psychopathological syndrome.

Abstract
In order for mathematical models to make credible contributions, it is essential for them to be verified and validated. Currently, verification and validation (V&V) of these models does not meet the expectations of the system biology and systems pharmacology communities. Partially as a result of this shortfall, systemic V&V of existing models currently requires a lot of time and effort. In order to facilitate systemic V&V of chosen hypothalamic-pituitary-adrenal (HPA) axis models, we have developed a computational framework named VeVaPy-taking care to follow the recommended best practices regarding the development of mathematical models. VeVaPy includes four functional modules coded in Python, and the source code is publicly available. We demonstrate that VeVaPy can help us efficiently verify and validate the five HPA axis models we have chosen. Supplied with new and independent data, VeVaPy outputs objective V&V benchmarks for each model. We believe that VeVaPy will help future researchers with basic modeling and programming experience to efficiently verify and validate mathematical models from the fields of systems biology and systems pharmacology.

Abstract
Whether melancholic depression is a distinct syndrome or not has long been debated. There are few studies providing information about the epidemiology of melancholic depression. In this study, we investigate the incidence rates, overall as well as by gender and age of onset of melancholic depression according to Taylor and Fink and corresponding DSM-IV disorders: major depressive disorder (MDD) with melancholic specifier, MDD with psychotic features, MDD with postpartum debut and bipolar depression in the Lundby population. Incidence rates with 95% confidence intervals were calculated. The incidence rate of melancholic depression was 0.48 (CI 0.36-0.61) per 1000 person-years under risk. The rates of the corresponding DSM-IV disorders were as follows: MDD with melancholic specifier 0.38 (CI 0.27-0.49), MDD with psychotic features 0.13 (CI 0.07-0.21), MDD with postpartum debut 0.02 (CI 0.00-0.06) and bipolar depression 0.04 (CI 0.01-0.10). Females had a significantly higher incidence rate, with a peak in age group 40-49, in melancholic depression according to Taylor and Fink and MDD with melancholic specifier. There was no gender difference in incidence rates of MDD with psychotic features or bipolar depression. The diagnoses were set in retrospect and the number of subjects with MDD with postpartum debut and bipolar depression was low. Incidence of melancholia was low in the Lundby Study. There was a female preponderance to become melancholically depressed in line with research on undifferentiated depression.

Abstract
OBJECTIVE The aim of this exploratory study was to compare the neurocognitive performance of patients undergoing melancholic and non-melancholic major depressive episodes. Considering potential limitations of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) specifier, we employed an additional tool that has proven useful in identifying melancholia (the Sydney Melancholia Prototype Index). METHODS One hundred forty-one depressed inpatients were classified as melancholic or non-melancholic according to the Sydney Melancholia Prototype Index and the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) criteria and compared on a neurocognitive battery selected to assess attention and processing speed, verbal memory, working memory and executive functions. Results were controlled for several potential confounders. RESULTS Patients diagnosed as melancholic by the two diagnostic systems displayed lower scores in executive measures, semantic verbal fluency and phonological verbal fluency. On attention and processing speed, patients with melancholia underperformed those with non-melancholic depression only when diagnosed by the Sydney Melancholia Prototype Index. After controlling for confounders, associations between melancholic status and executive dysfunction remained significant for the Sydney Melancholia Prototype Index but not for the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) diagnosis. CONCLUSION In this study, melancholia diagnosed by the Sydney Melancholia Prototype Index (but not by the Diagnostic and Statistical Manual of Mental Disorders [5th ed.] criteria) was characterized by a greater compromise of tests assessing executive functions than non-melancholic depressions, even after controlling for depressive severity. These preliminary results might contribute to generating hypotheses about differences in the cognitive profile and pathophysiological substrate between melancholic and non-melancholic depressions. Likewise, the pattern of findings supports the hypothesis that the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) melancholia specifier might identify more severe forms of depressive episodes rather than a qualitatively different subtype.

Abstract
My book From Melancholia to Depression: Disordered Mood in Nineteenth-Century Psychiatry charts how melancholia was reconceptualized in the nineteenth century as a modern mood disorder and a precursor to clinical depression. The book shows how this occurred chiefly in two ways. First, the idea of disordered mood as a medical concept was created through the appropriation of language from experimental physiology into the realm of psychopathology. Second, the interplay of statistical and diagnostic practices formed the basis for modern psychiatric classification and facilitated the standardization of melancholia as a psychiatric diagnosis. These developments were key to the reconceptualization of melancholia and the subsequent emergence of clinical depression, and were foundational to modern psychiatric theory and practice.

Abstract
PURPOSE Melancholia has recently been re-evaluated, because patients with major depressive disorder (MDD) were found to be heterogeneous. However, the DSM-5 criteria for melancholia (DSM-MEL) have been criticized, because of the difficulty in clearly distinguishing between melancholic and non-melancholic depression using DSM-MEL. Psychomotor disturbance (PMD) is one of the most important, as well as one of the only measurable symptoms of melancholia. Parker et al developed the CORE measure, which assesses PMD as a behavioral characteristic. The aim of our study was to objectively identify the subjective symptoms of melancholia by analyzing the symptoms associated with PMD. PATIENTS AND METHODS A total of 106 participants with MDD were examined by psychiatrists. Multiple regression analysis was performed in which the total CORE score was the dependent variable, and items of the DSM-MEL and historically suggested melancholic features were independent variables. RESULTS The following five independent variables were able to predict the total CORE score: 1) feelings of having lost feeling, 2) depressive delusions, 3) perplexity, 4) indecisiveness, and 5) no aggression against others. These five variables were more strongly associated with the total CORE score than the DSM-MEL. LIMITATION The major limitation of this study was that when choosing non-DSM melancholic signs and symptoms, we did not comprehensively evaluate and select the symptoms but chose items that are clinically important. CONCLUSION We identified five subjective symptoms that were associated with PMD. These five symptoms may be clinically useful as diagnostic criteria for melancholia.

Abstract
OBJECTIVES Clinically useful predictors of response to electroconvulsive therapy (ECT) are warranted, especially in the case of bipolar depression. The aim of this study was to explore the associations between response and its known and putative correlates. METHODS Six hundred seventy bipolar depressive patients treated with ECT were included in the study. The association between response (CGI-I ≤ 2) and mean seizure duration, number of treatments, age, sex, bipolar subtype, episode duration, HAM-D and YMRS scores, psychomotor disturbances and psychotic symptoms assessed through BPRS-EV were evaluated by means of univariate and multivariate logistic regression models, including quadratic and/or linear effects of continuous variables. RESULTS Four hundred eighty three patients (72%) were responders. Among known correlates of response, significant quadratic effects were found for seizure duration and number of treatments, while a linear association was confirmed for episode duration. Among putative correlates, severe motor retardation, tension or agitation, hyperactivity and delusions of guilt were significantly associated with response (p<.01) and a significant quadratic effect was found for YMRS score (p<.01). CONCLUSION Bipolar depressive patients with severe psychomotor disturbances, mood-congruent delusions and severe mixed features are highly responsive to ECT. A significant improvement in response prediction is expected when considering those clinical characteristics.

Abstract
BACKGROUND Six melancholic features (MFs) of the Hamilton Depression Rating Scale (HAM-D6) represent the construct of melancholia along a continuum of severity (from least to most severe: depressed mood, work and activities, somatic symptoms, psychic anxiety, guilty feelings, psychomotor retardation). We aimed to evaluate the association between these MFs and inflammatory cytokines (IC) in the blood. METHODS Each IC [interferon gamma (IFN-γ), tumor necrosis factor alpha (TNF-α), interleukin 2 (IL-2), IL-4, IL-6, IL-10, and IL-17] was associated with the HAM-D6 MFs of 139 severely depressed inpatients, using multiple linear regressions adjusted for covariates. Levels were compared with those of 100 healthy controls. RESULTS Depressed mood was associated with higher levels of IL-4 (β = 0.167; p = 0.041). Psychic anxiety: lower IL-17 levels (β = -0.173; p = 0.039). Guilt feelings: lower IL-2 levels (β = -0.168; p = 0.041) Psychomotor retardation: higher IL-6 levels (β = 0.195; p = 0.017). Depressed patients' TNF-α, INF-γ, and IL-4 levels were not significantly different from controls. Depressed patients' IL-2, IL-6, IL-10, and IL-17 levels were higher than those of controls (p <0.001). CONCLUSION Less severe MFs (depressed mood, psychic anxiety, and guilt feelings) were associated with an anti-inflammatory pattern (higher IL-4, lower IL-17 and lower IL-2, respectively). The presence of the most severe MF, psychomotor retardation, was associated with a higher pro-inflammatory response (higher IL-6).

Abstract
Objectives: Incident depression, occurring after an acute coronary syndrome (ACS) in never depressed patients, exerts a negative effect on the cardiac prognosis. Nonetheless only a few studies have evaluated the risk factor for incident depression and, particularly, no study have investigated the role of personality disorders. Therefore, the aim of this study is to verify if personality disorders represent a risk for incident depression in patients at their first ACS.Method: The study sample was selected among never depressed patients who were consecutively admitted to the Coronary Intensive Care Unit, from January 2009 to March 2012, for the first ACS. The study sample included 262 patients. The presence of depressive disorder was assessed with the Primary Care Evaluation of Mental Disorders (DSM-IV criteria), whereas its severity was evaluated with the Hospital Anxiety and Depression Scale. Evaluations were collected at baseline and at 1, 2, 4, 6, 9, 12 and 24 months of follow-up. Moreover, at baseline personality disorders were investigated with the Structured Clinical Interview for DSM-IV Axis II disorders.Results: Out of 262 subjects, a depressive disorder was diagnosed in 56 patients (21%). At baseline risk factors for incident depression were being widowed, having a distress reaction and narcissistic personality traits.Conclusion: Clinicians should keep in mind these characteristics when facing patients at their first ACS, given the detrimental effect of depression on cardiac prognosis. A psychological support should prevent the onset of incident depression in these patients.

Abstract
BACKGROUND The concept of melancholia has been associated with psychiatric nosology for centuries. Nevertheless, its definition, relationship to the contemporary concept of Major Depressive Disorder, and clinical implications remain uncertain. METHODS In a total sample of 3211 closely evaluated patient-subjects diagnosed with DSM-5 Major Depressive or Bipolar Disorder and meeting DSM-5 criteria for major depression with melancholic features or not at a European mood disorder center, we matched 1833 for depression severity (baseline HDRS21 score ≥18) and compared rates and ratings of characteristics of interest between the subgroups, using bivariate and multivariate methods. RESULTS Observed prevalence of melancholic features was 35.2% in the 1833 subjects matched for severity, and 21.0% among all 3211 subjects. Diagnosis was highly dependent on depression-severity measured three ways. Very few clinical characteristics differed between melancholic and nonmelancholic subjects matched for illness-severity; more suicidal ideation with melancholic features was a notable exception. CONCLUSIONS Study findings leave the distinction of melancholic features from depression-severity unclear and the potential clinical value of diagnosing melancholic features uncertain.

Abstract
Examining clinical features of depressive episodes may help elucidating the nature of association between depression and obesity, related to specific symptoms such as appetite and weight changes. This meta-analysis of observational studies evaluated whether subtypes of depression are associated with specific anthropometric profiles in adults. We searched MEDLINE, LILACS, PsycINFO, Scopus, Web of Science databases, and Grey Literature for articles published up to October 2016 that examined depressive subtypes and adiposity measures among adults. The pooled effect size was estimated with random effects models. The PRISMA guidelines were adopted to reporting results, and this review was registered in PROSPERO (CRD42016035685). A total of 22 articles were included in this systematic review, of which eight had data included in the meta-analysis, assessing 14 757 individuals with depression. Patients with atypical depression presented a 2.55 higher BMI score compared with those with melancholic depression. Subgroup analysis identified a differential distribution of anthropometric measures in studies conducted with Chinese populations. Among the remainder studies, only one reported discrepant results, possibly due to the exclusion of "weight change" in defining subtypes of depression. Atypical depression was significantly associated with elevated BMI compared with melancholic depression, deserving particular attention due to its clinical importance.

Abstract
OBJECTIVES Melancholic depression is a type of depression which is closely related to biological variables than are other types of depression. Its clinical features can be assessed using six items on the Hamilton Depression Rating Scale (HAM-D6 ). Previous studies have shown, using item response theory, that the symptom depressed mood is the least severe melancholic feature; work and activities, somatic symptoms and psychic anxiety are of moderate severity; and feelings of guilt and psychomotor retardation are the most severe. We aimed to evaluate whether the more severe melancholic signs or symptoms were associated with decreases in brain-derived neurotrophic factor (BDNF) levels. METHODS A total of 151 severely depressed inpatients had their BDNF levels analyzed by comparing those who presented with each HAM-D6 melancholic feature to those for whom the HAM-D6 feature was absent, using multiple linear regressions. The levels of BDNF of patients who presented with each melancholic feature were also compared with those of 100 healthy controls. RESULTS Depressed patients' median BDNF level was 44.06 ng/mL (interquartile range [IQR]: 33.99-62.4 ng/mL), and controls' median BDNF level was 65.22 ng/mL (IQR: 49.87-76.08 ng/mL) (P < .001). The presence of depressed mood, work and activities, somatic symptoms, psychic anxiety, and guilty feelings was not associated with BDNF levels. However, the presence of psychomotor retardation was associated with reduced BDNF (median reduction -10.07 ng/mL; 95% confidence interval [CI]: -19.43 to -0.71; P = .03). CONCLUSIONS To the best of our knowledge, this study is the first to associate BDNF levels with melancholic features in a sample of severely depressed inpatients. The main finding of this study was that severely depressed inpatients who presented the most severe melancholic feature, psychomotor retardation, had significantly reduced BDNF levels in the blood.

Abstract
The aim of this study was to explore outcome to antidepressants profile in melancholic unipolar depression. We conducted a systematic review of electronic databases and meta-analysis of randomized and nonrandomized trials comparing: 1) outcome to antidepressants and placebo between melancholic and non-melancholic depression; 2) outcome to different antidepressant classes in melancholic depression. Two outcomes were considered: clinical remission and response. Significant lower odds of remission to antidepressants in melancholic than in non-melancholic depressions were found. Although no significant differences were observed in the response to antidepressants between both subtypes of depression, those with melancholic features had lower odds of response to placebo. Finally, treatment of melancholic depression with serotonin reuptake inhibitors was associated with lower odds of remission compared with tricyclic antidepressants, and similar outcome compared with venlafaxine. Melancholia seems to show a differential pattern of outcome to antidepressants, which could be clinically valuable for a better implementation of personalized medicine of depression. Due to several limitations, further research is needed to support these preliminary findings.

Abstract
BACKGROUND The link between the abnormalities of the Hypothalamic-pituitary-adrenal (HPA) axis and depression has been one of the most consistently reported findings in psychiatry. At the same time, multiple studies have demonstrated a stronger association between the increased activation of HPA-axis and melancholic, or endogenous depression subtype. This association has not been confirmed for the atypical subtype, and some researchers have suggested that as an antinomic depressive subtype, it may be associated with the opposite type, i.e. hypo-function, of the HPA-axis, similarly to PTSD. The purpose of this systematic review is to summarise existing studies addressing the abnormalities of the HPA-axis in melancholic and/or atypical depression. METHOD We conducted a systematic review in the literature by searching MEDLINE, PsycINFO, OvidSP and Embase databases until June 2017. The following search items were used: "hypothalamic-pituitary-adrenal" OR "HPA" OR "cortisol" OR "corticotropin releasing hormone" OR "corticotropin releasing factor" OR "glucocorticoid*" OR "adrenocorticotropic hormone" OR "ACTH" AND "atypical depression" OR "non-atypical depression" OR "melancholic depression" OR "non-melancholic depression" OR "endogenous depression" OR "endogenomorphic depression" OR "non-endogenous depression". Search limits were set to include papers in English or German language published in peer-reviewed journals at any period. All studies were scrutinized to determine the main methodological characteristics, and particularly possible sources of bias influencing the results reported. RESULTS We selected 48 relevant studies. Detailed analysis of the methodologies used in the studies revealed significant variability especially regarding the samples' definition comparing the HPA axis activity of melancholic patients to atypical depression, including healthy controls. The results were subdivided into 4 sections: (1) 27 studies which compared melancholic OR endogenous depression vs. non-melancholic or non-endogenous depression or controls; (2) 9 studies which compared atypical depression or atypical traits vs. non-atypical depression or controls; (3) 7 studies which compared melancholic or endogenous and atypical depression subtypes and (4) 5 studies which used a longitudinal design, comparing the measures of HPA-axis across two or more time points. While the majority of studies did confirm the association between melancholic depression and increased post-challenge cortisol levels, the association with increases in basal cortisol and basal ACTH were less consistent. Some studies, particularly those focusing on reversed vegetative symptoms, demonstrated a decrease in the activity of the HPA axis in atypical depression compared to controls, but the majority did not distinguish it from healthy controls. CONCLUSIONS In conclusion, our findings indicate that there is a difference in the activity of the HPA-axis between melancholic and atypical depressive subtypes. However, these are more likely explained by hypercortisolism in melancholia; and most often normal than decreased function in atypical depression. Further research should seek to distinguish a particular subtype of depression linked to HPA-axis abnormalities, based on symptom profile, with a focus on vegetative symptoms, neuroendocrine probes, and the history of adverse childhood events. New insights into the dichotomy addressed in this review might be obtained from genetic and epigenetic studies of HPA-axis related genes in both subtypes, with an emphasis on the presence of vegetative symptoms.

Abstract
Currently, the diagnosis of major depressive disorder (MDD) mainly relies on clinical examination and subjective evaluation of depressive symptoms. There is no non-invasive, quantitative test available today for the diagnosis of MDD. In MDD, exploration of biomarkers will be helpful in diagnosing the disorder as well as in choosing a treatment, and predicting the treatment response. In this article, it is aimed to review the findings of suggested biomarkers such as growth factors, cytokines and other inflammatory markers, oxidative stress markers, endocrine markers, energy balance hormones, genetic and epigenetic features, and neuroimaging in MDD and to evaluate how these findings contribute to the pathophysiology of MDD, the prediction of treatment response, severity of the disorder, and identification of subtypes. Among these, the findings related to the brain-derived neurotrophic factor, the hypothalamo-pituitary-adrenal axis, cytokines, and neuroimaging may be strong candidates for being biomarkers MDD, and may provide critical information in understanding biological etiology of depression. Although the findings are not sufficient yet, we think that the results of epigenetic studies will also provide very important contributions to the biomarker research in MDD. The availability of biomarkers in MDD will be an advancement that will facilitate the diagnosis of the disorder, treatment choices in the early stages, and prediction of the course of the disorder.

Abstract
BACKGROUND Depression is a common disorder in both men and women, and the recurrence rate is high. The aim of this study was to identify risk factors for recurrence in depression in the Lundby Study. METHODS The Lundby Study is a community-based longitudinal study with focus on mental health. The study started in 1947 and three follow-ups have been carried out since, the last one in 1997. The population consists of 3563 subjects. Data from 508 subjects afflicted by depression was gathered. Premorbid factors (gender, socioeconomic status, marital status, personality and heredity) and factors related to the first depressive episode (age, degree of impairment and melancholic depression) were investigated regarding their influence on the risk for recurrence in depression. Multiple logistic regression was used in the calculations. RESULTS Risk factors associated with recurrent depression were melancholic depression at first onset (OR 3.52 [95% CI 1.62-7.66, p < 0.001]), young age as compared to old age at first onset (OR 0.51 [95% CI 0.28-0.92, p = 0.03]) and a premorbid nervous/tense personality (OR 1.77 [95% CI 1.22-2.56, p < 0.01]). Demographic factors, including gender, had no effect on the odds of recurrence. LIMITATIONS The Lundby Study spans over 50 years, making the results vulnerable to changes in diagnostic regimes and recall bias. CONCLUSION Melancholia at onset, regardless of severity of symptoms, had the greatest impact on the risk of recurrence in depression in the Lundby Study. Information about risk factors for recurrence in depression are useful in offering effective preventive measures in the form of psychotropic drugs and psychotherapy, and deciding the length of follow-up.

Abstract
OBJECTIVES Melancholic features of depression (MFD) seem to be a unidimensional group of signs and symptoms. However, little importance has been given to the evaluation of what features are related to a more severe disorder. That is, what are the MFD that appear only in the most depressed patients. We aim to demonstrate how each MFD is related to the severity of the major depressive disorder. METHODS We evaluated both the Hamilton depression rating scale (HDRS-17) and its 6-item melancholic subscale (HAM-D6) in 291 depressed inpatients using Rasch analysis, which computes the severity of each MFD. Overall measures of model fit were mean (±SD) of items and persons residual = 0 (±1); low χ2 value; p>0.01. RESULTS For the HDRS-17 model fit, mean (±SD) of item residuals = 0.35 (±1.4); mean (±SD) of person residuals = -0.15 (±1.09); χ2 = 309.74; p<0.00001. For the HAM-D6 model fit, mean (±SD) of item residuals = 0.5 (±0.86); mean (±SD) of person residuals = 0.15 (±0.91); χ2 = 56.13; p = 0.196. MFD ordered by crescent severity were depressed mood, work and activities, somatic symptoms, psychic anxiety, guilt feelings, and psychomotor retardation. CONCLUSIONS Depressed mood is less severe, while guilt feelings and psychomotor retardation are more severe MFD in a psychiatric hospitalization. Understanding depression as a continuum of symptoms can improve the understanding of the disorder and may improve its perspective of treatment.

Abstract
Here we consider interpersonal experience in schizophrenia, melancholia, and mania. Our goal is to improve understanding of similarities and differences in how other people can be experienced in these disorders, through a review of first-person accounts and case examples and of contemporary and classic literature on the phenomenology of these disorders. We adopt a tripartite/dialectical structure: first we explore main differences as traditionally described; next we consider how the disorders may resemble each other; finally we discuss more subtle but perhaps foundational ways in which the phenomenology of these disorders may nonetheless be differentiated. These involve disruptions of common sense and conventionality, abnormalities of empathy, distinct forms of paranoia and the sense of personal centrality, and altered perceptions of intentionality, deadness, and artificiality. We end by considering some neurocognitive research relevant to these abnormal forms of subjectivity, including work on theory of mind, experience of human movement, and perception of faces.

Abstract
BACKGROUND Depression research has been trying to improve the response rates to treatments by identifying a valid set of differential predictor variables. Potential candidates have been proposed, one of which were different subtypes of depression. However, the results on the predictive quality of subtypes on treatment are conflicting. METHODS The analyzed data consisted of Hamilton Depression Rating Scales (HAM-D17) of 879 depressive inpatients, which were recruited in a naturalistic multicenter study. Mean length of stay was 9.9 weeks. In a first step, a Latent Class Analysis (LCA) was conducted to classify the patients into smaller groups. In a second step, the class variable was included in a Linear Mixed Effects model to predict the same patients' response to treatment. RESULTS Five classes were obtained from LCA, showing substantially different symptom profiles. One of the classes, with a symptom profile similar to melancholic depression, showed substantially slower response to treatment (i.e., estimated time to remission; 11.3 weeks) than the remaining classes in the study (6.6-8.6 weeks). LIMITATIONS The applied measurement instrument, the HAM-D17, did not include items for two additional, frequently found subtypes of depression: psychotic and atypical depression. Thus, these subtypes could not emerge in the LCA. Furthermore, there was no systematic variation of treatment in the data. Thus, a differential effect of the classes on treatment could not be measured. CONCLUSIONS The classification of patients according to their symptom profiles seems to be a potent predictor for treatment response. However, the obtained symptom patterns are not completely congruent with the theoretically proposed subgroups. Against the background of the results, dividing melancholic depression in a rather cognitive and vegetative subtype may be promising.

Abstract
BACKGROUND The CORE measure has proved useful in rating observed psychomotor disturbance (PMD), which has been held to be a key feature of melancholic depression. However, studies have shown a substantial percentage of subjects fulfilling DSM criteria for melancholia do not have observable PMD. METHODS A semi-structured interview schedule was used in assessing and diagnosing depressed older patients. DSM-IV diagnoses were made, and the CORE measure was used to rate PMD. Comparisons were made between melancholia inpatients who scored low and those scoring high on the CORE in relation to presentation and pattern of symptoms. RESULTS Of 32 inpatients with melancholia, 10 scored 0-7, 8 scored 8-10, and 14 scored 15 or more on the CORE. Thirty-two inpatients with psychotic depression scored 13 or more. High-CORE participants manifested unvarying depression more often than did low-CORE participants, and were less likely to state that stress precipitated their depressive episode. CONCLUSIONS High-CORE melancholia cases appear to have more in common with psychotic depression than do low-CORE cases. Designation of observable PMD as an essential criterion in making a diagnosis of melancholia could increase the utility of the DSM classification in relation to treatment planning.

Abstract
High community prevalence estimates of DSM-defined major depressive disorder (MDD) have led to proposals to raise MDD's diagnostic threshold to more validly distinguish pathology from normal-range distress. However, such proposals lack empirical validation. We used MDD recurrence rates in the longitudinal 2-wave Epidemiologic Catchment Area Study to test the predictive validity of three proposals to narrow MDD diagnosis: a) excluding "uncomplicated" episodes (i.e., episodes that last no longer than 2 months and do not include suicidal ideation, psychotic ideation, psychomotor retardation, or feelings of worthlessness); b) excluding mild episodes (i.e., episodes with only five to six symptoms); and c) excluding nonmelancholic episodes. For each proposal, we used lifetime MDD diagnoses at wave 1 to distinguish the group proposed for exclusion, other MDD, and those with no MDD history. We then compared these groups' 1-year MDD rates at wave 2. A proposal was considered strongly supported if at wave 2 the excluded group's MDD rate was not only significantly lower than the rate for other MDD but also not significantly greater than the no-MDD-history group. Results indicated that all three excluded groups had significantly lower recurrence rates than other MDD (uncomplicated vs. complicated, 3.4% vs. 14.6%; mild vs. severe, 9.6% vs. 20.7%; nonmelancholic vs. melancholic, 10.6% vs. 19.2%, respectively). However, only uncomplicated MDD's recurrence rate was also not significantly greater than the MDD occurrence rate for the no-MDD-history group (3.4% vs. 1.7%, respectively). This low recurrence rate resulted from an interaction between uncomplicated duration and symptom criteria. Multiple-episode uncomplicated MDD did not entail significantly elevated recurrence over single-episode cases (3.7% vs. 3.0%, respectively). Uncomplicated MDD's general-distress symptoms, transient duration, and lack of elevated recurrence suggest it may generally represent nonpathologic intense sadness that should be addressed in treatment guidelines and considered for exclusion from MDD diagnosis to increase the validity of the MDD/normal sadness boundary.

Abstract
BACKGROUND Patients with depression display neurobiological changes of the hypothalamic-pituitary axis as well as cognitive disturbances. AIMS To assess any association between hypothalamus-pituitary-adrenal (HPA) axis reactivity and memory-related cognitive functions. METHODS Depressed outpatients (n = 83, ICD-10) were group-matched to healthy controls (n = 33), and tested on a number of cognitive domains. Salivary samples were collected at awakening, 30 min later and at 22:00 h. At 23:00 h, the participants ingested 1.0 mg of dexamethasone, and three saliva samples were collected the following day at the same times. RESULTS Patients and controls did not differ on any memory-related cognitive skills. After dexamethasone the cortisol level was 1.7 nmol/l higher (95% CI 0.0-2.8, P = 0.05) in depressed patients compared with controls. In the control group, but not in the patients, a positive association between post-DST cortisol and Rey's Complex figure test (1.3; 95% CI 0.3-3.6; P = 0.02) was found. We found no significant associations between other memory functions and cortisol measures. CONCLUSIONS Contrary to our hypothesis, we found a positive association between cortisol levels after dexamethasone and visuo-spatial memory primarily driven by the healthy controls. Otherwise, no association were found between HPA axis reactivity and memory-related cognitive function.

Abstract
OBJECTIVE To assess sociodemographic, clinical and treatment factors as well as depression outcome in a large representative clinical sample of psychiatric depressive outpatients and to determine if melancholic and atypical depression can be differentiated from residual non-melancholic depressive conditions. SUBJECTS/MATERIALS AND METHOD A prospective, naturalistic, multicentre, nationwide epidemiological study of 1455 depressive outpatients was undertaken. Severity of depressive symptoms was assessed by the Hamilton Depression Rating Scale (HDRS) and the Self Rated Inventory of Depressive Symptomatology (IDS-SR(30)). IDS-SR(30) defines melancholic and atypical depression according to DSM-IV criteria. Assessments were carried out after 6-8 weeks of antidepressant treatment and after 14-20 weeks of continuation treatment. RESULTS Melancholic patients (16.2%) were more severely depressed, had more depressive episodes and shorter episode duration than atypical (24.7%) and non-melancholic patients. Atypical depressive patients showed higher rates of co-morbid anxiety disorders and substance abuse. Melancholic patients showed lower rates of remission. CONCLUSION Our study supports a different clinical pattern and treatment outcome for melancholic and atypical depression subtypes.

Abstract
Theoretischer Hintergrund: Das BDI-II deckt mit 21 Depressionssymptomen die Breite der Depression ab und ist geeignet, die Symptomstruktur der Depression zu erforschen. Eine Vielzahl an faktorenanalytischen Studien erbrachte aber bislang keinen Konsens. Fragestellung: Nonmetrische Multidimensionale Skalierung (NMDS) soll daher die divergierenden Resultate einordnen und ein Modell der Symptomstruktur schaffen. Methode: Mittels NMDS wird die Symptomstruktur des BDI‐II (N = 266 Depressive) in einen 2‐dimensionalen Raum abgebildet. Ergebnisse: Die NMDS‐Lösung legt eine Facettenstruktur nahe, welche von den faktorenanalytischen Modellen bislang unzulänglich erfasst wird. Schlussfolgerungen: Neben einem generellen Kernsyndrom finden sich fünf spezifische Facetten (verminderte Aktivierung, psychovegetative Symptome, gesteigerte Aktivierung, Hoffnungslosigkeit und negative Einstellung zum Selbst), die die Heterogenität der Symptomatik innerhalb der Depression aufzeigen und damit die Existenz von Subtypen in der Depression nahelegen.

Abstract
Major depressive disorder (MDD) is a heterogeneous illness for which there are currently no effective methods to objectively assess severity, endophenotypes, or response to treatment. Increasing evidence suggests that circulating levels of peripheral/serum growth factors and cytokines are altered in patients with MDD, and that antidepressant treatments reverse or normalize these effects. Furthermore, there is a large body of literature demonstrating that MDD is associated with changes in endocrine and metabolic factors. Here we provide a brief overview of the evidence that peripheral growth factors, pro-inflammatory cytokines, endocrine factors, and metabolic markers contribute to the pathophysiology of MDD and antidepressant response. Recent preclinical studies demonstrating that peripheral growth factors and cytokines influence brain function and behavior are also discussed along with their implications for diagnosing and treating patients with MDD. Together, these studies highlight the need to develop a biomarker panel for depression that aims to profile diverse peripheral factors that together provide a biological signature of MDD subtypes as well as treatment response.

Abstract
Current gold standard approaches to the treatment of depression include pharmacotherapeutic and psychotherapeutic interventions with social support. Due to current controversies concerning the efficacy of antidepressants in randomized controlled trials, the generalizability of study findings to wider clinical practice and the increasing importance of socioeconomic considerations, it seems timely to address the uncertainty of concerned patients and relatives, and their treating psychiatrists and general practitioners. We therefore discuss both the efficacy and clinical effectiveness of antidepressants in the treatment of depressive disorders. We explain and clarify useful measures for assessing clinically meaningful antidepressant treatment effects and the types of studies that are useful for addressing uncertainties. This includes considerations of methodological issues in randomized controlled studies, meta-analyses, and effectiveness studies. Furthermore, we summarize the differential efficacy and effectiveness of antidepressants with distinct pharmacodynamic properties, and differences between studies using antidepressants and/or psychotherapy. We also address the differential effectiveness of antidepressant drugs with differing modes of action and in varying subtypes of depressive disorder. After highlighting the clinical usefulness of treatment algorithms and the divergent biological, psychological, and clinical efforts to predict the effectiveness of antidepressant treatments, we conclude that the spectrum of different antidepressant treatments has broadened over the last few decades. The efficacy and clinical effectiveness of antidepressants is statistically significant, clinically relevant, and proven repeatedly. Further optimization of treatment can be helped by clearly structured treatment algorithms and the implementation of psychotherapeutic interventions. Modern individualized antidepressant treatment is in most cases a well-tolerated and efficacious approach to minimize the negative impact of otherwise potentially devastating and life-threatening outcomes in depressive disorders.

Abstract
OBJECTIVE Several studies have reported clinical and biological differences between early- and late-onset(EO and LO) depression, which suggest different underlying aetiological processes. The aim of the present study is to examine whether there are differences between EO and LO depressed patients with melancholy, controlling for current age, with regard to clinical variables, vascular risk factors and family history of affective disorders or suicide. METHODS One hundred and twenty-one melancholic patients were divided into three groups: patients with current age and onset earlier than 60 (N = 60), patients aged 60 or over and with onset at 60 or later(N = 30) and patients aged 60 or over and with onset before the age of 60 (N = 31). Systematic clinical data were collected with the structured interview ’The Schedule for Affective Disorders and Schizophrenia’. Symptom ratings at admission and at discharge were assessed by means of the 21-item Hamilton Depression Rating Scale, the Hamilton Anxiety Scale and the Widlöcher Depression Retardation Scale. Family history of affective disorders or suicide was obtained using the Family History Research Diagnostic Criteria. Vascular risk factors were also recorded. RESULTS The only symptoms that differed across the groups were feelings of anger and irritability, which scored lower in the LO older group. No other significant differences were found in the variables studied. CONCLUSION According to this study, LO depression with melancholia should not be considered as a distinct entity. Further studies on EO and LO-depression should consider this diagnostic subtype, among others, as a key variable.

Abstract
BACKGROUND The recognition and assessment of psychomotor retardation may have implications for better definition of the clinical phenotypes of depression. The aim of this study was to assess the clinical correlates of psychomotor retardation endorsed at any time during the patients' lifetime (LPR). METHODS The study sample included 291 patients with non-psychotic major depressive disorder (MDD) participating in the clinical trial, "Depression: The Search for Treatment-Relevant Phenotypes." Psychomotor retardation was measured using a factor derived from the Mood Spectrum Self-Report (MOODS-SR) assessment. Using a pre-defined cut-off score on the lifetime psychomotor retardation (LPR) factor of the MOODS-SR, participants were classified into high and low scorers. Logistic regression analysis was used to evaluate the relationship between LPR and subthreshold bipolarity. RESULTS Compared to low scorers, participants with high scores on the LPR factor had greater severity of depression and more bipolarity indicators. CONCLUSIONS The MOODS-SR appears to be helpful to identify clinical phenotypes of unipolar depression and to highlight the usefulness of a lifetime approach to the assessment of psychopathology in the characterisation of patients with unipolar depression.

Abstract
Longitudinal high-risk research has provided convergent evidence that major mood and psychotic disorders often develop from nonspecific antecedents in predisposed people over time and development. For example, bipolar disorder (BD) appears to evolve from nonspecific childhood antecedents, including anxiety and sleep problems, followed by adjustment and minor mood disturbances through early adolescence, culminating in major mood episodes in later adolescence and early adulthood. Therefore, the current cross-sectional symptom-based diagnostic approach requires rethinking: it considers neither the familial risk nor the longitudinal clinical course, with the consequence that the early stages of illness are not recognized as belonging to the end-stage disorder. Emerging evidence of identifiable clinical stages in the development of BD has tremendous potential for early identification, development of stage-specific treatments, and advancing our understanding of the pathophysiology associated with illness onset and progression. The clinical staging model also has direct implications for the optimal organization of clinical services for high-risk youth. Specifically, specialty psychiatric programs are needed that break down traditional institutional barriers to provide surveillance and timely comprehensive psychiatric assessment during the entire risk period, from childhood through to early adulthood. In this regard, the development of specialty psychiatric programs aiming to identify youth in the early stages of evolving psychosis are substantially ahead of services for youth in the early stages of evolving major mood disorders.

Abstract
To evaluate the role of severe depression, i.e., depression with melancholic and/or psychotic features and alcohol dependence in suicide and undetermined death. The Lundby Study is a prospective, longitudinal study of a population consisting of 3563 subjects. In a long-term follow up 1947-2006 there were 66 suicide cases, including 19 undetermined deaths. Depression and alcoholism were as expected the major contributors to suicide (44% and 23% respectively). Severe depression with psychotic and/or melancholic features was diagnosed in 66% of all depressions and in 29% of all suicide cases, as compared to 15% for major depression only. Alcohol dependence was related to undetermined death. Major depressive disorder with melancholic and/or psychotic features appears to be an important contributor to accomplished suicide in the depression group, and alcohol dependence appears to be related to undetermined death.

Abstract
Previous research has shown that psychotic major depression (PMD) is often associated with higher rates of nonsuppression on the dexamethasone suppression test (DST) compared with nonpsychotic major depression (NMD), suggesting the potential importance of cortisol hypersecretion in the psychotic subtype of the disorder. However, these patient groups also are known to differ from one another on a variety of other clinical variables, and there are numerous factors independent of diagnostic status known to affect the DST. Thus, we investigated possible confounds that could help account for the apparent DST abnormalities in PMD sometimes reported in past research. Hospitalized patients with PMD (n = 11) and NMD (n = 58) were compared on the DST and other clinical variables. As expected, PMD patients showed significantly higher rates of DST nonsuppression (55% vs. 24%; p = 0.04). However, PMD patients also had significantly higher levels of anxiety severity (p = 0.01). The higher rates of nonsuppression in the PMD group were attenuated when these patients were compared with a subsample of NMD patients matched on anxiety severity (55% vs. 55%). Implications for future research on biological markers of PMD are discussed.

Abstract
Core symptoms of depression are a combination of psychological and somatic symptoms, often combined with psychomotor and cognitive disturbances. Diagnostic classification of depression including the concepts of melancholic, endogenous, or severe depression describe severely depressed patients suffering from most of the core symptoms, together with clinical characteristics of a cyclic unipolar or bipolar course, lower placebo response rates, higher response rates to electroconvulsive therapy, to antidepressant treatments with dually or mixed modes of action, or to lithium augmentation. Higher rates ofhypothalamic-pituitary-adrenal axis hyperactivity and specific electroencephalograph patterns have also been shown in this patient group. Summarizing the symptomatology of depression in these patients, a broad overlap between the abovementioned subgroups can be suggested. Because the positive diagnosis of those core symptoms of depression may include clinical consequences, it would be of use to integrate all the mentioned concepts in the upcoming new versions of the diagnostic systems DSM-V and ICD-11.

Abstract
OBJECTIVE The long-term suicide risk of depression was evaluated in a community sample by severity and gender. METHOD The Lundby study is a prospective, longitudinal cohort study on a population consisting of 3563 subjects. In 1947-1997 medium or severe depression according to the Lundby diagnostic system were registered in 503 subjects. The same subjects were also diagnosed according to DSM-IV showing major depressive disorder (MDD) in 293 and depressive disorder not otherwise specified (DDNOS) in 131 subjects. RESULTS The overall long-term suicide risk varied from 5.6% to 6.8%. The long-term suicide risk was 3.1% for medium and 11.4% for severe 'Lundby depression', 3.7% for medium and 13.8% for severe MDD + DDNOS, 3.1% for medium and 13.7% for severe MDD. Severity and male sex were risk factors for suicide. CONCLUSION Males with a severe depression showed a high long-term risk for suicide, around 20%.
