These are extremely important studies. Many medical folks working with neuropathic disorders think that many diagnosed as "idiopathic" have IGT. It is vital that anybody not yet diagnosed accurately have proper testing for IGT, ideally a five hour GT test with both glucose and insulin measured.

I am so glad to see some research that does not try to explain a disease by using genes. Turning all illness into a hunt for the "responsible" genes threatens to undermine progress in health care.

It took an awful long time to finally overthrow the idea that the brain and nervous system were not immutable and in fact have great plasticity. Hopefully there will be a renewed trend towards taking charge of our own health. Science and scientific research can help but not if it slants perspective by giving too much control to genes and such.
