Obsessive Compulsive Disorder Symptoms and their Association with Trichotilomania, Tic and Body Dysmorphic Disorders

Background: Obsessive-compulsive disorder (OCD) symptoms and the related disorders are subsumed under chronic psychiatric disorders which are of psychosocial and therapeutic importance. In most studies, the mean age of onset of significant OCD symptoms is adolescence period. The aim of this study was to evaluate OCD symptoms, Tic disorder, Body Dysmorphic Disorder (BDD) and Trichotilomania amon...

Tic disorders and obsessive compulsive disorder: where is the link?

Over the last years evidence on the overlap between tic-disorders (TD) and obsessive compulsive behavior/disorder (OCB/OCD) has increased. The main focus of research have been the phenomenological and epidemiological similarities and differences in samples of different age, primary diagnosis (TD vs. OCD) including the co-occurrence of both. Unfortunately, only a minority of studies included all...

The relationship of body dysmorphic disorder and eating disorders to obsessive-compulsive disorder.

Body dysmorphic disorder (BDD) and eating disorders are body image disorders that have long been hypothesized to be related to obsessive-compulsive disorder (OCD). Available data suggest that BDD and eating disorders are often comorbid with OCD. Data from a variety of domains suggest that both BDD and eating disorders have many similarities with OCD and seem related to OCD. However, these disor...

Treating obsessive-compulsive and tic disorders.

Obsessive-compulsive disorder versus body dysmorphic disorder: a comparison study of two possibly related disorders.

The relationship between obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD) is unclear. BDD has been proposed to be an OCD-spectrum disorder or even a type of OCD. However, few studies have directly compared these disorders' clinical features. We compared characteristics of subjects with OCD (n=210), BDD (n=45), and comorbid BDD/OCD (n=40). OCD and BDD did not significantly ...

Cross-Disorder Genetic Analysis of Tic Disorders, Obsessive–Compulsive, and Hoarding Symptoms

Hoarding, obsessive-compulsive disorder (OCD), and Tourette's disorder (TD) are psychiatric disorders that share symptom overlap, which might partly be the result of shared genetic variation. Population-based twin studies have found significant genetic correlations between hoarding and OCD symptoms, with genetic correlations varying between 0.1 and 0.45. For tic disorders, studies examining the...
