Too much copper in the system damages the cells of the liver and leads to cirrhosis. Neurological damage primarily occurs in the putamen and globus pallidus, collectively known as the lenticular nucleus. Symptoms of the disease include a peculiar type of tremor in the upper extremities, slowness of movement and changes in temperament. Persons may become exceptionally argumentative, overly emotional or may experience a decrease in mental capabilities. The disease first affects the liver, and if treatment is administered early enough, damage to the nervous system is dramatically reduced.
Treatment includes the elimination of copper containing foods such as chocolate and mushrooms.
Patients are also given drugs to chelate excess copper and eliminate it from the body.
