OBJECTIVE This study examined whether d-cycloserine, a partial agonist at the N-methyl-D-aspartate (NMDA) glutamatergic receptor, enhances the efficacy of behavior therapy for obsessive-compulsive disorder (OCD). METHOD A randomized, double-blind, placebo-controlled trial investigating D-cycloserine versus placebo augmentation of behavior therapy was(More)
Evidence suggests that the antibiotic d-cycloserine (DCS) enhances the treatment effects of exposure and response prevention (ERP) for Obsessive-Compulsive Disorder (OCD).

BACKGROUND Body dysmorphic disorder (BDD) is a highly distressing and impairing disorder characterized by a preoccupation with imagined or slight physical defects in appearance. Well designed studies on its prevalence and on base rates for diagnostic criteria are rare. Therefore this study aimed to reveal prevalence rates of BDD in the general population(More)
Individuals with obsessive-compulsive disorder (OCD) have difficulties in organizing information during encoding associated with subsequent memory impairments. This study was designed to investigate whether impairments in organization in individuals with OCD can be alleviated with cognitive training. Thirty-five OCD subjects and 36 controls copied and(More)
Tourette syndrome (TS) is characterized by chronic motor and vocal tics. Habit reversal therapy (HR) is a behavioral treatment for tics which has received recent empirical support. The present study compared the efficacy of HRT in reducing tics, improving life-satisfaction and psychosocial functioning in comparison with supportive psychotherapy (SP) in(More)
