Ganser

Ganser syndrome is a rare type of mental disorder characterized by nonsensical or wrong answers to questions and other dissociative symptoms. It is also known as nonsense syndrome, balderdash syndrome, syndrome of approximate answers, hysterical pseudodementia or prison psychosis. The syndrome is classified by the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) as a dissociative disorder not otherwise specified.

Symptoms

The most notable symptom of Ganser syndrome is giving approximate answers to simple questions that should be known, a symptom known as vorbeigehen. Other symptoms may include hallucinations, conversion disorder, hysteria, and amnesia.

Causes

The exact cause of Ganser syndrome is unknown. However, it is often associated with severe stress and is more common in males. It is also often seen in prisoners, which is why it is sometimes referred to as prison psychosis.

Diagnosis

Diagnosis of Ganser syndrome is based on the patient's symptoms. The DSM-IV criteria for diagnosis include the presence of approximate answers, the presence of other dissociative symptoms, and significant distress or impairment.

Treatment

Treatment for Ganser syndrome typically involves psychotherapy and, in some cases, medication. The prognosis is generally good, with most patients recovering fully with treatment.
