Abstract
Obsessive compulsive disorders (OCD) may be encountered after basal ganglia lesions of various aetiologies. These lesions are usually bilateral. We report here the case of a 24 years old man who developed a pure compulsive behavior after a unilateral left-sided caudate nucleus hemorrhage due to a cavernoma. The pathophysiology of this compulsive disorder probably reflects a frontal cortex deafferentation mechanism. Behavioral, psychological and medical (serotoninergic) treatments are usually proposed but the efficacy of such therapy remains to be investigated in secondary OCD.
