It goes over the connection between mitochondrial damage and peripheral neuropathy.
As an explanation as to how dysfunctional mitochondrial lead to peripheral neuropathy, the article notes that:
“He and his colleagues suspected that the reason (for peripheral neuropathy) might lie within mitochondria, the parts of cells that generate energy. While mitochondria for most cells in the body have a relatively quick turnover — replacing themselves every month or so — those in nerve cells often live much longer to accommodate the sometimes long journey from where a cell starts growing to where it ends. The nerve cells that supply the feet are about 3 to 4 feet long in a person of average height, Hoke explains. Consequently, the mitochondria in these nerve cells take about two to three years to travel from where the nerve originates near the spine to where it ends in the foot.”
