Case studies in neuropsychiatry II: Conversion pseudodementia
A patient is described who experienced pseudodementia as a conversion reaction. The patient was considered to be demented originally because of the evidence for profound cognitive impairment elicited on mental state examination. Careful analysis of the patient's verbal production in unstructured situations and of her behavior in the hospital permitted a clinical diagnosis of pseudodementia to be made, a diagnosis confirmed by response to treatment and long term followup. Evidence is presented to support the interpretation of her pseudodementia as a conversion reaction.
