Comparison of working memory capacity of obsessive-compulsive patients with control group

Abstract

Background: The memory deficit or forgetfulness hypothesis of obsessive-compulsive disorder (OCD) has been used to explain the maintenance of repetitive behaviors in patients, yet the majority of studies focusing on memory show inconsistent results.
