The Obsessive-Compulsive Spectrum Disorders are a group of entities related to the Obsessive-Compulsive Disorder having similarities with it and also differences that are characteristic of each disorder. Nowadays, they are published in different chapters of current diagnosis manuals. On the one hand, entities of the impulsive spectrum can be found, and on the other hand, entities of the compulsive pole can also be found. However, these entities will soon be included in the same chapter for a better analysis and debate. The present article aims at analyzing the clinical and epidemiological characteristics and the therapeutic management of the three most important disorders of the impulsive spectrum: the pathological gambling, the trichotillomania and the self-injury behaviour.
