EPA-0589 - Toc and Psychosis: when Obsessions Become Delusions

Abstract

For many years it has raised a possible association between obsessive and psychotic disorders.

To enter in this topic, we present the case of a 6 year old's patient who presented tics, coprolalia, obsessive-compulsive symptoms (contamination, symmetry, accumulation) and behavioral disorders being diagnosed of Tourette's disorder. With the use of specific treatment remained stable until age 12 when obsessive thoughts changed from absurds ranges to delusional ranges causing behavioral disorganization.

Furthermore, delirious humor, depersonalization and delusions were added. This led to increase the dose of antidepressants with a partial response of obsessives symptoms and persistance of psychotics symptoms; so it was Aripiprazole treatment required.

Subsequently it was attempted to remove the antipsychotic drug, but it was not achieved because delirious symptoms reappeared. Finally, the patient was diagnosed of Tourette's disorder and undifferentiated schizophrenia.

Thus, We might consider that exist a link between the obsessives and psychotics symptom?. We present a review of the literature in order to elucidate the association between the two entities.
