Onset of neuropsychiatric symptoms after psychological trauma may result in erroneous diagnostic bias

Abstract

We report a case of neuroacanthocytosis, which was misdiagnosed as conversion disorder. Because the onset was after a psychologically stressful physical trauma, the patient's symptoms were interpreted in terms of psychological regression. The case clearly points out the defects of descriptive psychiatric diagnosis, especially in the area of somatoformal disorders. It also reminds the clinicians to keep in mind rare neurological disorders as possible causes for psychiatric symptoms.
