Shoplifting associated with normal-pressure hydrocephalus: report of a case.

A 52-year-old woman who had been apprehended for shoplifting was found to have normal-pressure hydrocephalus due to aqueduct stenosis. We ascribe the shoplifting to impairment of social judgment, which was one of the observed features of a dementia. Cerebrospinal fluid diversion by means of a ventriculo-peritoneal shunt resulted in resolution of her symptoms.
