An emotional Stroop task with four word types (panic threat, obsessive-compulsive threat, general threat, and neutral) and two presentation conditions (supraliminal, subliminal) was used in two experiments. The first experiment involved 21 panic disorder (PD) patients and 20 normal controls; the second experiment 20 PD patients and 20 obsessive-compulsive patients. PD patients, obsessive-compulsive patients, and normal controls did not differ in Stroop interferences. In addition, there were no significant correlations between reduction of PD symptoms and differences between pre- and post-treatment Stroop response latencies.

Background: Obsessive-compulsive disorder (OCD) is a complex condition marked by persistent distressing thoughts and repetitive behaviours. Despite its prevalence, the mechanisms behind OCD remain elusive, and current treatments are limited. This protocol outlines an investigative study for individuals with OCD, exploring the potential of psilocybin to improve key components of cognition implicated in the disorder.

Background: Cross-sectional studies have reported neurocognitive performance deficits in obsessive-compulsive disorder (OCD), particularly on tasks assessing response inhibition and proactive control over stimulus-driven behaviors (task control). However, it is not clear whether these deficits represent trait-like markers of OCD or are state-dependent.
Methods: This study examined performance on two neurocognitive tasks in OCD patients (N = 26) before and after cognitive behavioral therapy (CBT) and matched healthy controls (HCs, N = 19).

Background: Clomipramine, a Tricyclic Antidepressant (TCA), is known for its efficacy in treating Obsessive-compulsive Disorder (OCD). However, it is associated with several side effects, including urinary retention. This case report discusses the case of a 20-year-old male with OCD who developed urinary retention following clomipramine administration.

Anorexia nervosa (AN) and obsessive-compulsive disorder (OCD) often share multiple similar symptoms and are highly comorbid; however, the common and distinct brain neuroanatomy of these two diseases are unclear. The current study attempted to identify the overlapping and different gray matter volume (GMV) between AN and OCD. We conducted a voxel-wise meta-analysis of GMV using the latest Seed-based d Mapping with Permutation of Subject Images Toolbox (SDM-PSI) software.

Objective: Obsessive compulsive disorder (OCD) and anorexia nervosa (AN) are conditions associated with poor cognitive flexibility, a factor considered to interfere with treatment, but research into the relationship between cognitive flexibility and treatment outcome is limited. This study explores whether baseline measures of cognitive flexibility predict outcomes in OCD and AN, evaluates whether changes in these measures contribute to treatment outcome, and evaluates the effectiveness of adjunctive cognitive remediation therapy (CRT) in improving cognitive flexibility.
Methods: This secondary analysis utilized linear mixed model analysis on data from a randomized controlled multicenter clinical trial involving adult participants with OCD (n=71) AND AN (n=61).
