Selective cognitive deficits in obsessive‐compulsive disorder compared to panic disorder with agoraphobia

Abstract

OBJECTIVE: Visual-spatial and executive functions deficits have been reported in obsessive-compulsive disorder (OCD). We investigated their specificity comparing cognitive function in OCD, panic disorder with agoraphobia (PD/A) and controls by a comprehensive neuropsychological battery. METHOD: Fifty-five subjects (25 OCD, 15 PD/A, 15 controls) without current depressive episode underwent structured clinical interview for DSM-IV, Yale-Brown Obsessive Compulsive Scale, Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale. Neuropsychological battery assessed: executive functions, visual discrimination, spatial memory and learning, verbal memory, general intellectual functioning. RESULTS: OCD showed controlled fluency, visual-spatial construction, learning and memory deficits; PD/A spatial learning impairment. OCD was discriminated from PD/A and controls by three tests scores, predicting group membership for 76.4% of the cases. CONCLUSION: Visual-constructive and controlled fluency deficits seem specific in OCD, while the spatial learning deficit, shared with PD patients, may not be disorder-specific, but anxiety-related. Results support the proposed ventral frontal-striatal circuit involvement in OCD.
