Copper in health test tubes that damaged DNA in the cells of a Menkes patient can be repaired. In time, the procedures needed to repair damaged genes in the human body may be found. Wilson's disease is a rare autosomal (chromosome 13) recessive genetic disorder of copper transport that causes an excess of copper to build up in the liver. This results in liver toxicity, among other symptoms. The disease is now treatable. Wilson's disease is produced by mutational defects of a protein that transports copper from the liver to the bile for excretion. The disease involves poor incorporation of copper into ceruloplasmin
Brain damage neuroregeneration can occur in the peripheral nervous system but is much rarer and more difficult to assist in the central nervous system (brain or spinal cord). However, in neural development in humans, areas of the brain can learn to compensate for other damaged areas, and may increase in size and complexity and even change function, just as someone who loses a sense may gain increased acuity in another sense - a process termed neuroplasticity. There are many misconceptions that revolve around brain injuries and brain damage. One misconception is that if someone has brain damage then they cannot fully recover.
