Ganser syndrome
From Wikipedia, the free encyclopedia
Ganser syndrome is a rare psychiatric disorder known as a factitious disorder. It is characterised by the individual mimicking behaviour they think is typical of a psychosis; usually by providing nonsensical or wrong answers to questions, and doing things incorrectly. It is also sometimes called nonsense syndrome, balderdash syndrome, syndrome of approximate answers, pseudodementia or prison psychosis. This last name, prison psychosis, is sometimes used because the syndrome occurs most frequently in prison inmates, where it may represent an attempt to gain leniency from prison or court officials.
Ganser is an extremely rare variation of factitious disorder. It is a reaction to extreme stress and the patient thereby suffers from approximation or giving absurd answers to simple questions. The syndrome can sometimes be diagnosed as merely malingering, however, it is more often defined as FD.
Symptoms include a clouding of consciousness, somatic conversion symptoms, confusion, stress, loss of personal identity, Echolalia, and Echopraxia. Individuals also give approximate answers to simple questions. For example, "How many legs are on a cat?", to which the subject may respond '3'.
[edit] Overview
The original description by Sigbert Josef Maria Ganser in 1898 pointed out their hysterical twilight state. They may also describe hallucinations which are usually more florid than those in schizophrenia. They may also have disorders of sensation similar to those in conversion disorder. They may be inattentive or drowsy.
Some workers believe there is a genuine psychosis underlying this, others believe it is a dissociative disorder, while still others believe it is the result of malingering. Over the years, opinions have seemed to move from the first view more towards the last.
[edit] Diagnosis
Diagnosing Ganser syndrome is very challenging, not only because some measure of dishonesty is involved but also because it is very rare.
Usually when giving wrong answers they are only slightly off showing that the individual understood the question. For instance, when asked how many legs a horse has they might say, "five." Also, although subjects appear confused in their answers, in other respects they appear to understand their surroundings.
[edit] Prevelance
The disorder is extrodinarily rare with less than 100 recorded cases. While individuals of all racial backgrounds have been reported with the disorder, there is a higher inclination towards males (75% or more). The average age of those with Ganser syndrome is 32 and it stretches from ages 15-62 years old.
