In most cases, it is preceded by extreme stress and followed by amnesia for the period of psychosis. In addition to approximate answers, other symptoms include a clouding of consciousness, somatic conversion disorder symptoms, confusion, stress, loss of personal identity, echolalia, and echopraxia. Cause
To date, no definitive cause or reason of the disorder has been established. The sources that classify the syndrome as a dissociative disorder or a factitious disorder conflict in their proposed aetiologies. As a result, there are differing theories as to why the syndrome develops. Ganser syndrome was previously classified as a factitious disorder, explaining the symptoms as mimicking of what patients who do not experience psychosis believe is typical of the experience. However, the DSM-IV placed the syndrome under "Dissociative Disorders Not Otherwise Specified". There has been evidence of a strong correlation between approximate answers and amnesia, suggesting that these have an underlying dissociative mechanism.Both Gansers syndrome and the broader category of dissociative disorders have been linked to histories of hysteria, psychosis, conversion, multiple personality and possible feigning. Despite this, the conditions aetiology remains under question due to associations with established psychiatric disorders, as well as organic states. According to Stern and Whiles (1942), Ganser syndrome is a fundamentally psychotic illness.
These include effort-based tests such as grip and pinch strength, diagnostic tests such as Finkelsteins test for De Quervains tendinitis, Phalens contortion, Tinels percussion for carpal tunnel syndrome, and nerve conduction velocity tests that show nerve compression in the wrist. Various imaging techniques can also be used to show nerve compression such as x-ray for the wrist, and MRI for the thoracic outlet and cervico-brachial areas. Utilization of routine imaging  is useful in early detection and treatment of overuse injuries in at risk populations, which is important in preventing long term adverse effects. Treatment
There are no quick fixes for RSI. Early diagnosis is critical to limiting damage. For Upper Limb Repetitive Strain Injury (RSI), Occupational Therapists create interventions that include education to facilitate ergonomics. This will minimize the possibility of an upper limb strain injury by learning the correct approach during facilitating functional task movements. The RICE treatment is used as the first treatment for many muscle strains, ligament sprains, or other bruises and injuries. RICE is used immediately after an injury happens and for the first 24 to 48 hours after the injury. These modalities can help reduce the swelling and pain. Commonly prescribed treatments for early-stage RSIs include analgesics, myofeedback, biofeedback, physical therapy, relaxation, and ultrasound therapy. Low-grade RSIs can sometimes resolve themselves if treatments begin shortly after the onset of symptoms. However, some RSIs may require more aggressive intervention including surgery and can persist for years.Although there are no "quick fixes" for RSI, there are effective approaches to its treatment and prevention.
