Obsessive compulsive disorder (OCD) is associated with a moderate degree of underperformance on cognitive tests, including deficient processing speed. However, despite little research focusing on Intelligence Quotient (IQ) in OCD, it has long been speculated that the disorder is associated with elevated intellectual capacity. The present meta-analytic study was, therefore, conducted to quantitatively summarize the literature on IQ in OCD systematically. We identified 98 studies containing IQ… 
Impaired test performance yet spared neurocognitive functioning in individuals with obsessive-compulsive disorder: the role of performance mediators
Neurocognitive impairment in OCD is likely exaggerated and researchers should report the percentage of participants displaying performance deficits rather than mean group differences alone; the latter obscures the high percentage of patients without impairment and thus may unduly foster stigma in this population.
Neurocognitive risk markers in pediatric obsessive-compulsive disorder.
Investigating longitudinal trajectories and predictive significance of neurocognition in those affected by, and at risk for, early-onset OCD is warranted and will enhance individualized risk stratification and inform future prevention and early intervention strategies.
Executive functions and insight in OCD: a comparative study
Differences suggest that the neuropsychological profile of poor-insights patients is different from their good-insight counterparts, emphasize the role played by the executive functions in insight and highlights the need for more accurate neurocognitive research and treatment.
Prevalence and correlates of cognitive impairment among OCD patients
Assessing the cognition in OCD and its relation with CRP, ESR levels found cognitive function in OCD patient was correlated with ESR,CRP, YBOCS and BDI scores, and patients with OCD appear to have cognitive deficits.
Neurocognitive deficits in obsessive–compulsive disorder: A selective review
Overall, neuropsychological deficits further support the role of frontostriatal circuits in the neurobiology of OCD and emerging literature also suggests the important role of other areas, in particular parietal cortex.

Toward identifying reproducible brain signatures of obsessive-compulsive profiles: rationale and methods for a new global initiative
By recruiting a large, ethno-culturally diverse sample, this research will test whether there are robust biosignatures of core OCD features that transcend countries and cultures and can be used to reveal trans-diagnostic disease dimensions, chart when these signatures arise during development, and identify treatments that target these circuit abnormalities directly.


The neuropsychology of adult obsessive-compulsive disorder: a meta-analysis.
Differences in Neuropsychological Performance Between Subtypes of Obsessive–Compulsive Disorder
Overall the results suggested greater impairments in performance on neuropsychological tasks in checkers relative to other subtypes of OCD, although the observed effects were small and the conclusions limited by the small subtype samples.
Cognitive functioning in obsessive-compulsive disorder: a meta-analysis
Patients with OCD appear to have wide-ranging cognitive deficits, although their impairment is not so large in general, indicating the need to select carefully the test forms and methods of testing used in future research.
Neurocognitive profile analysis in obsessive-compulsive disorder
Findings of specific abnormalities on tasks of motor and processing speed are consistent with a hypothesized role of thalamocortical and basal ganglia regions in the pathogenesis of OCD.
Inhibitory control and psychopathology: A meta-analysis of studies using the stop signal task
An inhibition deficit in ADHD is confirmed, and it is suggested that comorbid ADHD has different effects on inhibition in patients with ANX, ODD/CD, and RD.
Executive function and nonverbal memory in obsessive-compulsive disorder
Meta-analysis of intellectual and neuropsychological test performance in attention-deficit/hyperactivity disorder.
Findings indicate that overall cognitive ability is significantly lower among persons with ADHD and that FSIQ may show as large a difference between ADHD and control participants as most other measures.
Prospective, longitudinal study of tic, obsessive-compulsive, and attention-deficit/hyperactivity disorders in an epidemiological sample.
Tics and OCD were significantly associated in this sample, as were OCD and ADHD, and these findings are in general consistent with those from family studies, and they help to define the natural history, comorbid illnesses, and interrelatedness of these conditions.
Executive functions and the obsessive-compulsive disorder: on the importance of subclinical symptoms and other concomitant factors.
Confirming the main hypothesis, few neuropsychological differences emerged between the OCD and healthy participants when concomitant factors were controlled and subclinical symptoms appeared to play a different and independent role on the cognitive results.
