BackgroundExisting neuropsychological studies of obsessive–compulsive disorder (OCD) are cross-sectional and do not provide evidence of whether deficits are trait-related (antecedent and independent of symptomatology) or state-related (a consequence, dependent on symptomatology).AimsTo investigate whether there are premorbid neuropsychological deficits associated with adult OCD.MethodLongitudinal data were collected from participants of the Dunedin Multidisciplinary Health and Developmental study. Neuropsychological data collected at age 13 were linked with age 32 diagnosis of OCD.ResultsThe group who had OCD at age 32 differed significantly from the control group with no OCD on their performance at age 13 on neuropsychological tests of visuospatial, visuoconstructive and visuomotor skills, controlling for gender and socioeconomic status, but did not differ on tests of general IQ or verbal ability. Performance of the group with OCD on tests of executive functioning was mixed.ConclusionsIndividuals with OCD have premorbid impairment in visuospatial abilities and some forms of executive functioning, consistent with biological models of OCD.

Leibler Divergence

AbstractThe symptoms of obsessive–compulsive disorder (OCD) are largely related to impaired executive functioning due to frontostriatal dysfunction. To better treat OCD, the development of biomarkers to bridge the gap between the symptomatic-cognitive phenotype and brain abnormalities is warranted. Therefore, we aimed to identify biomarkers of impaired organizational strategies during visual encoding processes in OCD patients by developing an eye tracking-based Rey–Osterrieth complex figure test (RCFT). In 104 OCD patients and 114 healthy controls (HCs), eye movements were recorded during memorization of the RCFT figure, and organizational scores were evaluated. Kullback–Leibler divergence (KLD) scores were calculated to evaluate the distance between a participant’s eye gaze distribution and a hypothetical uniform distribution within the RCFT figure. Narrower gaze distributions within the RCFT figure, which yielded higher KLD scores, indicated that the participant was more obsessed with detail and had less organizational strategy. The OCD patients showed lower organizational scores than the HCs. Although no group differences in KLD scores were noted, KLD scores were significantly associated with organization T scores in the OCD group. The current study findings suggest that eye tracking biomarkers of visual memory encoding provide a rapidly determined index of executive functioning, such as organizational strategies, in OCD patients.

Competing Interest

Despite the neuropsychology literature provide reliable evidence of impaired executive functions in obsessive-compulsive disorder (OCD), it has not been determined whether these deficits are prior to onset of the disorder or they begin to appear as consequence. To investigate whether recent onset of OCD in adolescence is characterized by executive functioning difficulties in behavioral inhibition, attentional flexibility, and decision-making. Executive functions were compared in adolescents with recent (past year) appearance of OCD symptoms (n = 40) and control group (n = 40). Three computerized tests within the CANTAB battery were completed by all subjects (the Affective Go/No Go task, the Intra-Dimensional, Extra-Dimensional Set-Shifting task, and the Decision-Making task). Using one-way ANOVA showed that compared with control group, the OCD adolescents displayed a bias towards negative stimuli with less errors on sad and hopeless words on the Affective Go/No Go task. They also made faster decisions while they bet more of their available points compared to controls, in the Decision-Making task. Adolescents with recent OCD diagnosis (less than one year) showed greater attention towards sad and hopeless stimuli and more impulsive behavior when making decisions. However, they were able to switch attentional set to neutral stimuli. These findings suggest that executive functioning impairments can characterize adolescence OCD from early beginning of the disorder.Disclosure of interestThe author has not supplied his/her declaration of competing interest.

Performance Differences

Introduction: Studies have shown that patients with obsessive compulsive disorder (OCD) often perform more poorly than healthy control (HC) participants on cognitive tasks involving executive functions. Most studies, however, have been performed in Western countries and societies, making it uncertain whether impaired executive functions can also be observed among non-Western patients with OCD. To address this gap in the literature, we evaluated several executive functions in Chinese patients with OCD and HCs.Methods: Participants included consisted of 46 Chinese patients with OCD (25 men, 21 women), ranging in age from 19 to 56 years, and 45 matched HCs without any self-reported lifetime psychiatric disorder. They all lived in Shanghai or the surrounding area. Five tests of the Cambridge Neuropsychological Test Automated Battery (CANTAB) were used to evaluate several executive functions (response inhibition, spatial working memory, planning, and cognitive flexibility) along with testing basic learning and visual recognition memory. Statistical tests using a Bonferroni-corrected significance level of p = 0.003 were performed to assess overall patient-control group differences in cognitive performance. Additionally, we explored performance differences between patients classified as having either relatively mild symptoms or severe symptoms based on the individual total scores on the Yale-Brown Obsessive-Compulsive Scale.Results: There were no significant performance differences between patients with OCD and HC in any of the cognitive tests. Similarly, cognitive performance of patients with relatively mild OCD symptoms did not differ significantly from that of patients with severe symptoms.Conclusions: These results do not seem to support the view that impaired executive functioning represents a basic cognitive and pathophysiological feature of Chinese patients with OCD. However, due to study limitations, additional research is required before this conclusion can be well accepted.
