Introduction and objective: Diagnostic criteria of the Gilles de la Tourette syndrome hasn't changed in many years. Lately, associated symptoms have became very important. In this study, we want to stress the relationship between precocious diagnostic criteria, proposed by us, and the associated symptomatology, specially the obsessive-compulsive disorder.
Patients and methods: We have studied 30 patients with the diagnosis of Gilles de la Tourette syndrome with associated obsessive-compulsive disorder by means of our criteria, evaluating their fiability when confronted to the Shapiro et al and DSM III-R criteria.
Conclusions: New criteria, that we have named Muñoz-Gómez, were useful for the precocious diagnosis of this syndrome and for evaluation of the associated symptomatology.
