Psychosis and pseudo dementia associated with hemodialysis.

A patient treated with hemodialysis developed psychotic episodes, including visual hallucinations and delusions, as well as symptoms similar to the fatal dialysis dementia. His hospital course seems to demonstrate an original organic dysfunction with behavioral sequelae that were perpetuated by psychological difficulties. His tendency to overdramatize his disability and to adopt an excessively helpless and passive role made treatment difficult. A one-year followup is provided along with a discussion of the relationship of his case to dialysis dementia.
