Introduction And Objective:
Neuropsychological performance in obsessive compulsive disorder (OCD) and its association with disfunctions in neuroanatomic structures and clinical symptoms of disorder has been reviewed.
Development:
OCD symptoms and different aspects between children and adult psychopatology are presented. Briefly neurobiologic studies related with the etiology and patophisiology of OCD has been revised. This article summarizes some last studies about OCD cognitive functioning and its impairment.
Conclusion:
The more impaired cognitive functions in OCD are executive functions and visual abilities, specially non verbal memory. In addition, other studies have identified verbal memory deficits. These deficits are consistent with neurodevelopmental models, which hypothesizes that abnormalities of ventral prefrontal striatal and thalamic circuits may be involved in the etiology and patophisiology of OCD. The cognitive deficits could be functioning as a intermediate variable between neurobiological abnormalities and OCD symptoms. More studies are needed to analize the OCD cognitive impairment.
