Tarafder S, Bhattacharya P, Paul D, Bandyopadhyay G, Mukhopadhyay P - Indian J Psychiatry (2006)

Bottom Line: To study the relationship of neuropsychological disposition with the executive functions and cognitive style in patients with OCD.Subcortical-cerebellar-spinal domain of ANQ was found to be associated with cognitive style and executive functions.The impairment of executive functions and poor activation of specific neurological circuitry in OCD patients affirms the neurobiological basis of the disorder.

ABSTRACT

Background: Recent brain imaging and electrophysiological studies have consistently shown dysfunction of the fronto-striatal thalamic pathways in patients with obsessive-compulsive disorder (OCD).

Aim: To study the relationship of neuropsychological disposition with the executive functions and cognitive style in patients with OCD.

Methods: Twenty OCD patients (14 males, 6 females) and 20 normal control subjects, matched for all relevant variables including age, sex and education, were studied. Neuropsychological disposition was assessed on the Adult Neuropsychological Questionnaire (ANQ), the executive functions were assessed through Wisconsin Card Sorting Test (WCST), and the cognitive style was assessed by employing the Embedded Figure Test (EFT).

Results: Subcortical-cerebellar-spinal domain of ANQ was found to be associated with cognitive style and executive functions.

Conclusion: The impairment of executive functions and poor activation of specific neurological circuitry in OCD patients affirms the neurobiological basis of the disorder.

Figure 0001: Comparative status of the patients with OCD and normal controls on Adult Neuropsychological Questionnaire

Mentions: The data obtained on 8 domains of ANQ have been given in Table 1 and graphically represented in Fig. 1. Table 1 shows that the patients with OCD obtained significantly higher scores, denoting a deficit with respect to their neuro-psychological status on all the variables of ANQ except in the domains of SA and S/P. The failure of the domain of SA to distinguish the two groups may be owing to the criteria of exclusion of substance abusers from the study. As expected, the OCD being an anxiety disorder with intact judgement and insight, showed no difference on the domains of S/P function from their normal counterparts.
