Current Diabetes Reports Aims and scope Submit manuscript

Abstract

The DCCT/EDIC (Diabetes Control and Complications Trial/ Epidemiology of Diabetes Interventions and Complications) provides a comprehensive characterization of the natural history of diabetic neuropathy in patients with type 1 diabetes and provides insight into the impact of intensive insulin therapy in disease progression. The lessons learned about the natural history of distal symmetrical polyneuropathy and cardiovascular autonomic neuropathy and the impact of glycemic control on neuropathy are discussed in this review.
