Mood-congruent and mood-incongruent psychotic symptoms in major depression: The role of severity and personality
Background: Whether psychotic symptoms in major depression (MD) are better explained by a severity model or by a vulnerability model, with personality as a predisposing factor, is still debated. The aim of the present study was to evaluate in MD the relationship between the content of psychotic features (mood congruent (MC) or mood incongruent (MI)) and severity of depression or personality traits. Methods: 62 inpatients affected by MD with psychotic features were divided into three groups on the basis of the content of psychotic symptoms: MC, MI, mixed MC-MI. All subjects completed the SCID-IV, the Structured Clinical Interview for DSM-IV Personality Disorders and the Hamilton Rating Scale for Depression. Personality was assessed after MD remission. Results: MI psychotic symptoms were positively associated with schizotypal traits, whereas MC symptoms were positively related to obsessive-compulsive traits and severity of depression. Patients with both MC and MI psychotic symptoms were characterized by a personality profile and depression severity standing in a middle position between the MC and MI groups. Limitations: The main limitations of the study are represented by the small sample size, the time of assessment of personality and the inclusion of only unipolar depression. Conclusions: Our findings suggest that both depression severity and personality profile, independently from each other, model the content of psychotic symptoms, confirming the validity of subgrouping psychotic depression into two distinct MC and MI types and supporting the inclusion of a third mixed MC-MI type because of its intermediate position in personality profile and severity between the MC or MI group. © 2012 Elsevier B.V
The TAS-20 more likely measures negative affects rather than alexithymia itself in patients with major depression, panic disorder, eating disorders and substance use disorders
Background This study evaluates whether the difference in Toronto Alexithymia Scale-20 item (TAS-20) between patients with major depression (MD), panic disorder (PD), eating disorders (ED), and substance use disorders (SUD) and healthy controls persisted after controlling for the severity of anxiety and depression. Methods Thirty-eight patients with MD, 58 with PD, 52 with ED, and 30 with SUD and 78 healthy controls (C) completed the TAS-20, the Hamilton Rating Scale for Anxiety (Ham-A), the Hamilton Rating Scale for Depression (Ham-D). Results The differences in TAS-20 scores observed between patient groups, regardless of the type of their disorders, and controls disappeared after controlling for the effect of anxiety and depression severity. In contrast, the differences in severity of anxiety and depression between patients and controls were still present, after excluding the effect of alexithymic levels. Conclusions Our data suggest that alexithymic levels, as measured by the TAS-20, are modulated by the severity of symptoms, supporting the view that alexithymia can represent a state phenomenon in patients with MD, PD, ED and SUD, because the TAS-20 seems overly sensitive to a general distress syndrome, and it is more likely to measure negative affects rather than alexithymia itself. \ua9 2014 Elsevier Inc
The effect of severity and personality on the psychotic presentation of major depression
The aim of the present study was to evaluate whether symptom severity or personality traits are associated with psychotic symptoms in major depression (MD), since it is still debated whether psychotic depression represents the most severe form of depression or the effect of personality structure. The study included 163 patients affected by MD who were divided into four groups on the basis of the presence/absence of melancholic features and psychotic symptoms. All subjects completed the Structured Clinical Interview for DSM-IV Disorders (SCID-IV), the Structured Clinical Interview for DSM-IV Personality Disorders (SIDP-IV) and the Hamilton Rating Scale for Depression (Ham-D). Personality was assessed after MD remission (absence of DSM-IV criteria and Ham-D score lower than 7 for at least 2 months). Psychotic symptoms were positively associated with symptom severity (higher Ham-D total score) and with paranoid and schizotypal traits and negatively related to histrionic traits. Our data support the view that the effect of paranoid-schizotypal traits and symptom severity on the presence of psychotic symptoms in MD occurs separately and they are independent of each other. © 2011 Elsevier Ltd
Late-onset obsessive-compulsive disorder associated with left cerebellar lesion
The onset of obsessive-compulsive disorder (OCD) after age 50 is rare and generally related to an organic etiology. An involvement of fronto-striatal circuits has been strongly suggested, whereas cerebellum remains so far scarcely explored. We present here the description of a "pure" late-onset OCD associated with a cerebellar lesion, neither comorbid with other mental disorders nor with neurological syndromes. To our knowledge, this condition was not previously described in literature. The patient is a 62-year-old woman who developed a late-onset OCD associated with a left cerebellar lesion due to an arachnoid cyst in the left posterior fossa. We debate the possible role of the cerebellar lesion in favoring a transition from a predisposing liability (namely an obsessive-compulsive personality disorder and a depressive status) to the onset of OCD in this woman. \ua9 2014 Springer Science+Business Media
Obsessive-compulsive symptoms interact with disorganization in influencing social functioning in schizophrenia
Objective: Recent research has suggested a dual impact of obsessive-compulsive dimension on functioning in schizophrenia with a gradual transition from an improving to a worsening effect depending on obsessive-compulsive symptoms (OCS) severity (from mild to moderate-severe). Aim of the present study was to investigate whether this varying effect of OCS on functioning might be mediated or moderated by schizophrenia symptom dimensions or occur independently. Method: Seventy-five patients affected by schizophrenia were administered the Structured Clinical Interview for DSM-IV Disorders, the Positive and Negative Syndrome Scale, the Yale-Brown Obsessive-Compulsive Scale and the Social and Occupational Functioning Assessment.The sample was divided into two groups according to the severity of OCS (absent/mild and moderate/high OCS group). Results: In both groups, the effect of OCS on functioning was not mediated by their effect on positive, negative or disorganization symptoms. Conversely, a significant interaction between OCS and disorganization dimension was found: the dual effect of OCS on functioning occurred only among patients with low disorganization symptoms while it was no more apparent at high levels of disorganization. Conclusion: Data suggest that in patients with schizophrenia, functioning at least in part depends on the interaction between disorganization and OCS
Obsessive–compulsive symptom severity in schizophrenia: a Janus Bifrons effect on functioning
The impact of obsessive–compulsive symptoms on functioning in schizophrenia is still debated. This study investigated the relationship between OC symptoms and functioning along a severity gradient of obsessive–compulsive dimension. Sixty patients affected by schizophrenia completed the SCID-IV, the Positive and Negative Syndrome Scale, the Yale-Brown Obsessive–Compulsive Scale and the Social and Occupational Functioning Assessment Scale. The relationship between functioning and obsessive–compulsive dimension was described by a reverse U-shaped curve; functioning was positively related to the presence of mild obsessive–compulsive symptoms and inversely related to moderate and severe symptoms, after controlling for the severity of positive, negative, disorganization and general psychopathological symptoms. The role of obsessive–compulsive symptoms on social functioning in schizophrenia occurs along a severity continuum with a gradual transition from a positive correlation (from absent to mild symptoms) to an inverse correlation (for symptoms ranging from moderate to severe) and independently from schizophrenia symptom dimensions
Delusional disorder: The role of personality and emotions on delusional ideation
The relationship between personality and Delusional Disorder in still debated. The present study aimed to evaluate the role of personality features and emotional dispositions on the proneness to delusional beliefs, through the lens of a dimensional approach. 91 outpatients were administered the Structured Interview for DSM-IV Personality Disorders, the Pathological Narcissism Inventory, the Positive and Negative Affect Schedule and the Peters et al. Delusions Inventory. Delusion proneness was positively related to the "Hiding the Self" domain of narcissistic vulnerability and to paranoid traits and negatively related to "Positive Affect". Paranoid traits and "Hiding the Self" significantly interacted in influencing delusion ideation. These data suggest that proneness to delusion depends, at least in part, on a complex interplay between specific emotional and paranoid dispositions within personality
Predictors of symptomatic remission in patients with first-episode schizophrenia: A 16 years follow-up study
Objective Recent views on schizophrenia outcome and treatment suggest that symptomatic remission is possible, and a definition of remission has been proposed by the Remission in Schizophrenia Working Group (RSWG). This study evaluated whether patients who achieved remission after several years of illness (R) showed psychopathological differences at the onset of their disorder compared to non-remitted (NR) patients. Method Forty-eight patients with first-episode schizophrenia were evaluated with the Positive and Negative Symptoms Scale (PANSS) both at the onset of illness and after a mean period of 16 years. Patients were defined as R or NR according to the RSWG criteria. Results Eighteen patients (37.5%) were classified as R at follow-up. At onset, R patients showed a lower illness severity, less severe negative and general psychopathology symptoms compared to NR. Furthermore, they underwent fewer psychotic episodes than NR over the course of follow-up. Remission was predicted by lower severity of negative and general psychopathology symptoms at onset and by lesser number of psychotic episodes during follow-up. Conclusions The symptomatic remission may be a viable outcome in schizophrenia, particularly for patients with a mild illness and less severe negative symptoms at onset and with few psychotic episodes over time. \ua9 2014 Elsevier Inc
The role of alexithymia in predicting incident depression in patients at first acute coronary syndrome
Objective Alexithymia has been considered both to predispose to depression and to worsen cardiac prognosis after an acute coronary syndrome. Nonetheless, no studies have evaluated its role as a risk factor for incident depression, in patients with acute coronary syndrome. Methods In 251 consecutive patients, the presence of a first-ever depressive episode was evaluated with the Primary Care Evaluation of Mental Disorders at baseline and 1, 2, 4, 6, 9, 12 and 24 months after their first acute coronary syndrome. At baseline, patients completed the Toronto Alexithymia Scale (TAS-20) and the Hospital Anxiety and Depression Scale. Results Out of 251 subjects (80.9% males), a first-ever depressive episode was diagnosed in 66 patients. Depressed and never-depressed patients differed in female gender, living status, alexithymic scores at TAS-20 and depressive symptoms. Nonetheless, nor the TAS-20 factors nor its total score were predictive of developing a depressive episode in a Cox regression. Moreover, baseline differences in TAS-20 scores between the two groups, disappeared after controlling for anhedonic symptoms. Conclusion Our results do not support the hypothesis that alexithymia at TAS-20 is a risk factor for incident depression after acute coronary syndrome
