Differential effect of benzodiazepine sedation in high and low anxious patients in a "real life" stress setting.

abstract：RATIONALE:In recent years, an increasing body of evidence points to the involvement of the glutamatergic system and specifically the glutamatergic ionotropic N-methyl-D-aspartate (NMDA) receptor in the pathophysiology of obsessive-compulsive disorder (OCD). OBJECTIVES:To test the role of NMDA receptors in compulsive b...
