ABSTRACT Introduction: Research suggests that obsessive-compulsive disorder (OCD) is not a unitary entity, but rather a highly heterogeneous condition, with complex and variable clinical manifestations. Objective: The aims of this study were to compare clinical and demographic characteristics of OCD patients with early and late age of onset of obsessive-compulsive symptoms (OCS); and to compare the same features in early onset OCD with and without tics. The independent impact of age at onset and presence ...

The main goal of this study is to contribute to the understanding of the trajectory of comorbid disorders associated with obsessive-compulsive disorder (OCD) according to the first manifested psychiatric disorder and its impact in the clinical course of OCD and subsequent psychiatric comorbidities. One thousand and one OCD patients were evaluated at a single time point. Standardized instruments were used to determine the current and lifetime psychiatric diagnoses (Structured Clinical Interview for ...

Although obsessions and compulsions comprise the main features of obsessive-compulsive disorder (OCD), many patients report that their compulsions are preceded by a sense of "incompleteness" or other unpleasant feelings such as premonitory urges or a need perform actions until feeling "just right." These manifestations have been characterized as Sensory Phenomena (SP). The current study presents initial psychometric data for a new scale designed to measure SP.Seventy-six adult OCD subjects were probed ...

This study investigates the influence of age at onset of OCS on psychiatric comorbidities, and tries to establish a cut-off point for age at onset.Three hundred and thirty OCD patients were consecutively recruited and interviewed using the following structured interviews: Yale-Brown Obsessive Compulsive Scale; Yale Global Tic Severity Scale and the Structured Clinical Interview for DSM-IV. Data were analyzed with regression and cluster analysis.Lower age at onset was associated with a higher probability ...

Background: Recent studies using magnetic resonance spectroscopy ( 1 H-MRS) indicate that patients with obsessive–compulsive disorder (OCD) present abnormal levels of glutamate (Glu) and gamma aminobutyric acid (GABA) in the frontal and striatal regions of the brain. These abnormalities could be related to the hyperactivation observed in cortico-striatal circuits of patients with OCD. However, most of the previous 1 H-MRS studies were not capable of differentiating the signal from metabolites that overlap ...

Obsessive-compulsive disorder patients who do not improve sufficiently after treatment with a selective serotonin reuptake inhibitor might improve further if other drugs were added to the treatment regimen. The authors present a double-blind, placebo-controlled trial comparing the efficacy of adding quetiapine or clomipramine to a treatment regimen consisting of fluoxetine. Between May 2007 and March 2010, a total of 54 patients with a primary diagnosis of obsessive-compulsive disorder, as defined ...

Background Obsessive-compulsive spectrum disorders (OCSDs) are more frequent in patients with active or prior rheumatic fever (RF), suggesting that OCSD and RF may share underlying etiologic mechanisms. Our objective was to estimate the frequency of OCSD in first-degree relatives (FDRs) of RF patients and controls to determine whether there is a familial relationship between OCSD and RF. Methods This is a case-control family study. Of the 98 probands included in this study, 31 had RF without Sydenham' ...

Clinical and sociodemographic findings have supported that OCD is heterogeneous and composed of multiple potentially overlapping and stable symptom dimensions. Previous neuroimaging investigations have correlated different patterns of OCD dimension scores and gray matter (GM) volumes. Despite their relevant contribution, some methodological limitations, such as patient's previous medication intake, may have contributed to inconsistent findings.Voxel-based morphometry was used to investigate correlations ...

Obsessive-compulsive disorder (OCD) is a frequent, disabling disorder with high rates of treatment resistance. Transcranial direct current stimulation (tDCS) is a safe, tolerable noninvasive neuromodulation therapy with scarce evidence for OCD.

This study aimed to identify the factors associated with a delay in treatment-seeking among patients with obsessive-compulsive disorder (OCD), a disabling neuropsychiatric disorder. To achieve this purpose, we conducted a cross-sectional study examining latency to treatment (LTT) and its associated correlates in 863 patients with OCD. We defined LTT as the time lag between the awareness of discomfort and/or impairment caused by symptoms and the beginning of OCD-specific treatment. To determine the ...
