Psychiatric Times has posted a case description by Jeremy Matuszak and Matthew Parra (University of Nevada, Reno School of Medicine) involving a 40 year-old woman apparently suffering from Capgras syndrome.  While not recognized in the DSM-IV-TR as a discrete diagnosis, Capgras syndrome refers to a “delusion (or fixed false belief) in which the affected individual believes that another person, generally a family member or close acquaintance, has been replaced by a look-alike imposter.” As Matuszak and Parra note, the syndrome was first described by Joseph Capgras and Jean Reboul-Lachaux in 1923 and has historically been interpreted from both neuropsychological and psychodynamic vantage points.
