| Summary: | Among the cognitive abilities more studied recently are the executive functions(EF), that are essential in the execution of new tasks and able the individual commitment in goal directed actions. Executive dysfunctions are recognized in diverse psychiatric conditions, including the Obsessive-compulsive Disorder (OCD) and the Tourette Syndrome (TS). This theoretical revision aimed to extend the knowledge about the relation between EF damages and these mentioned disorders. In the greater part, the scientific studies in the area have presented a near association between the EF damage, the OCD, and the TS. However, there are researches that refute these findings, showing that there is still not a determinant theory about this relationship. Beyond that, even among the researches that share the relation between EF, OCD, and TS, is not possible affirm which specific executive abilities are injured in each case. Then, the study concludes that, even with the increase of the number of researches carried out, many questionings persist about the EF damage in psychiatric disorders. These data reveal the need of more researches about the subject,what can improve considerably the quality of the diagnoses,prognostics and treatments carried out.
