Abstract

Shared obsessions and compulsions are a very rare disorder known to be represented by very few case reports in the literature. We report a case of two sisters displaying similar obsessions and compulsions. Knowledge about clinical features, treatments and prognosis in shared obsessive-compulsive disorder is limited to a few cases. New cases need to be reported in order to provide new information and experience about the shared disorder.

Key words: Obsessive-compulsive disorder, shared disorders, shared psychotic disorder
