Copper toxicity, though sharing some similarities with Wilson's Disease, is different in that the latter is an inherited & rare genetic disorder which, like copper toxicity, causes copper to collect in the liver, brain and other body tissues, but has a more dire prognosis than copper toxicity, and for which a different treatment approach is .
