What is Which of the following is related to Ganser syndrome in a patient who is apparently healthy physically? and explain in detail?
Ganser syndrome (hysterical pseudodementia) is a condition in which the patient exhibits symptoms of an apparent dementia or psychosis that are too exaggerated or inconsistent to fit such a diagnosis. The patient may exhibit vorbeireden, a phenomenon in which the patient's incorrect answers imply knowledge of the correct answer. It is usually associated with global amnesia for a crime and a dissociative shut-down of intellectual processes, producing apparent dementia. Ref: Nurcombe B. (2008). Chapter 24.
