The role of traumatic experiences in the genesis of obsessive-compulsive disorder

This paper discusses the role of traumatic stress in the genesis of obsessi ve-compulsive disorder. While the early classical conditioning theory of th e onset of obsessive-compulsive disorder has only limited empirical support , authorities have always recognised the role of stress in precipitating th is disorder, and in triggering relapse in those who have been successfully treated. Here, clinical cases are cited that show a causal link between sev ere trauma and the onset of obsessive-compulsive disorder. The nature of th e traumatic reaction and the possible mechanisms by which it leads to frank obsessive compulsive disorder are discussed. The apparent links between th is and posttraumatic stress disorder are also explored. Finally, implicatio ns for therapy are considered. (C) 1999 Elsevier Science Ltd. All rights re served.
