Nervous system abnormality and nervous disease in diabetes.
Symptomatic diabetic neuropathy is present only in a few percent of the total diabetic population. In contrast abnormalities of the various parts of the nervous system can be demonstrated very early using neurophysiological techniques. These abnormalities are reversible at first, but progressive with duration of diabetes. Similar nervous abnormalities are present in experimental diabetes in the rat. The earliest structural changes have been demonstrated to be a decreased calibre of the myelinated axons. An abnormality in the axonal transport of proteins is possibly the very first change to appear. These recent results have enabled us to propose a hypothesis concerning the sequence of events in the development of the peripheral nerve abnormalities.
