Negative symptoms of schizophrenia have generally been found in association with ventricular enlargement and prefrontal abnormalities. These relationships, however, have not been observed consistently, most probably because negative symptoms are heterogeneous and result from different pathophysiological mechanisms. The concept of deficit schizophrenia (DS)(More)
A literature search, supplemented by an expert survey and selected reanalyses of existing data from epidemiological studies was performed to determine the prevalence and associated burden of bipolar I and II disorder in EU countries. Only studies using established diagnostic instruments based on DSM-III-R or DSM-IV, or ICD-10 criteria were considered.(More)
BACKGROUND The evolutionary consequences of love are so important that there must be some long-established biological process regulating it. Recent findings suggest that the serotonin (5-HT) transporter might be linked to both neuroticism and sexual behaviour as well as to obsessive-compulsive disorder (OCD). The similarities between an overvalued idea,(More)
CONTEXT Diagnostic criteria for eating disorders influence how we recognize, research, and treat eating disorders, and empirically valid phenotypes are required for revealing their genetic bases. OBJECTIVE To empirically define eating disorder phenotypes. DESIGN Data regarding eating disorder symptoms and features from 1179 individuals with clinically(More)
Previous studies on the comorbidity of Obsessive-Compulsive Disorder (OCD) have largely focused on comorbidity with major depressive and anxiety disorders. The present investigation deals with a more complex pattern of comorbidity involving bipolarity. Indeed, in a consecutive series of 315 OCD outpatients, 15.7% had such comorbidity (mostly with bipolar II(More)
OBJECTIVE This multicenter study aimed to verify whether the historical and psychopathological characteristics of a large group of patients with deficit schizophrenia were consistent with those reported in previous studies. The authors also tested the hypothesis that neurological and neuropsychological indices sensitive to frontoparietal dysfunction, but(More)
BACKGROUND Eating disorders and alcohol use disorders (AUDs) commonly co-occur, although the patterns of comorbidity differ by eating disorder subtype. Our aim was to explore the nature of the co-morbid relation between AUDs and eating disorders in a large and phenotypically well-characterized group of individuals. METHOD We compared diagnostic and(More)
Failure to recognize subthreshold expressions of mania contributes to the frequent under-diagnosis of bipolar disorder. There are several reasons for the lower rate of recognition of subthreshold manic symptoms, when compared to the analogous pure depressive ones. These include the lack of subjective suffering, enhanced productivity, ego-syntonicity, and(More)
In this report, which is an update of a guideline published in 2002 (Bandelow et al. 2002, World J Biol Psychiatry 3:171), recommendations for the pharmacological treatment of anxiety disorder, obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) are presented. Since the publication of the first version of this guideline, a(More)
Much evidence of an association between specific attachment styles and depression prompted us to investigate, in depressive disorders, the potential role of polymorphisms within the gene encoding the receptor of the main neurohormone involved in attachment processes, oxytocin. For this purpose, two single nucleotide polymorphisms (SNPs), 6930G>A (rs53576)(More)
