Neuropsychological disposition and its impact on the executive functions and cognitive style in patients with obsessive-compulsive disorder.

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.
